Design Statement

The Cambridge Biomedical Campus will provide an ideal location for

developing innovation-driven businesses and will also allow the expansion

of existing businesses operating from constrained sites elsewhere in the

region. In addition, it is anticipated that inward investment will be attracted

to the scheme from beyond the region’s current catchment potential.

Sustainable development is at the forefront of planning in Cambridge.

The aim of these proposals is a development that will provide a positive

contribution to the sustainable development of the City through balancing

the economic well-being of the City with the protection and enhancement of

the wider environment.

The development of the clinical and biomedical research campus and the

consequent employment generation should be considered in the context

of the proposed residential developments in the Southern Fringe which

will provide homes for many of the staff at the Cambridge Biomedical

Campus.

It is recognised that the needs of the city’s economy must be balanced with

a range of other factors to safeguard the quality of Cambridge’s unique

character and environment. These include:

• The need to reduce reliance on the private car by encouraging

more sustainable modes of transport i.e. walking, cycling and public

transport.

• The protection of the City’s historic character and setting.

• Nature conservation.

• Promotion and protection of public open space.

• Ensuring future occupiers of sites are adequately protected from issues

such as flood risk.

• The creation of contemporary, attractive environments, making sure that

existing environmental quality is enhanced through good urban design

in all areas.

Cambridge Local Plan Policy 9/5

The outline application for the expansion of Cambrige Biomedical Campus

is being submitted pursuant to Policy 9/5 of the Cambridge Local Plan 2006.

The principle land uses for this part of the Southern Fringe are as follows:

• ‘up to 10.3hectares for NHS and private clinical development. 2.2hectares

of this area is reserved for the possible relocation of Papworth hospital.

In the event of it not being needed for this use it would be available for

other clinical, higher education, or sui-generis medical research institute

uses.

• up to 14.4 hectares of employment land for commercial development,

comprising biomedical and biotechnology research and development

activities within Use Class B1(b), related support activities, related

higher education and sui-generis medical research institutes.

• up to 10.28 hectares of land will be safeguarded until after 2016 for

future clinical development and research uses’.

These areas relate to net developable land and exclude strategic

infrastructure such as the two spine roads, strategic landscaping, public

realm and the Cambridgeshire Guided Bus (CGB) route.

The application proposals conform to the agreed land allocations as detailed

above, although there is flexibility within certain areas to reflect the differing

requirements of potential end users, particularly in relation to the relocation

of Papworth Hospital.

Design Statement

Planning Context contd

Key Development Principles (extract from Cambridge Southern Fringe

Area Development Framework 2006)

• Development must not exceed 5 commercial storeys (plus associated

plant) along the western and southern boundaries in order to minimise

the impact on the adjoining countryside. Elsewhere on the site it may

be acceptable to go up to 6 commercial storeys (plus associated plant)

subject to detailed masterplanning. These heights represent maximum

overall building heights and will only be acceptable providing they do

not cause an unacceptable visual impact on the green corridor and the

countryside beyond.

• Development should be oriented to create ‘active frontages’ which

define streets and spaces.

• ‘Through traffic’ passing along the Addenbrooke’s Access Road should

not be allowed to exit on to Hills Road/ Babraham Road to the east. A

means of enforcing this control will need to be provided.• Buildings proposed for the northern part of the site should be organised

to form a clear ‘Central Hub’ for the development.

• The Cambridgeshire Guided Bus will enter the site from the western

boundary and a stop should be provided in the Central Hub as well as at

other agreed locations through the Addenbrooke’s site. The aim should

be to make public transport an attractive and viable alternative to the

private car.

• Land to the south is safeguarded until after 2016 for future clinical

development and research uses.

• Connections across the Green Corridor for all modes to Trumpington

should be maximised.

• Proposals should seek to integrate new and old development through a

comprehensive design approach.

Figure 5 - Location plan

Location

The application site is located immediately to the west of the existing

Addenbrooke’s campus on the southern fringe of Cambridge.

Boundaries

The western boundary of the main development site (excluding the new

primary substation) is defined by the main London - Cambridge rail line,

beyond which lies open agricultural land and the eastern perimeter of

Trumpington and the proposed Clay Farm residential development.

The northern boundary is defined by the southern perimeter of Long Road

Sixth Form College, whose playing fields separate the site boundary from

the school buildings.

The eastern boundary is defined by Robinson Way. Immediately to the

east of Robinson Way is the existing Addenbrooke’s campus, and the new

Elective Care Centre in particular. Robinson Way, a private road serving

the existing campus, runs down part of the eastern boundary before it turns

eastwards.

The southern boundary is defined by an open ditch that drains westwards

towards Hobson’s Brook, which lies to the west of the rail lines.

An area of land to the west of the railway line has been included in the

application for the provision of a new electricity substation. Whilst this will

be located beside the proposed CGB embankment and is likely to comprise

a built area of around 40x40 metres, a wider application boundary has

been included to reflect the vehicular access along farm tracks to the public

highway. The substation is essential to serve the development.

An area of agricultural land to the south is safeguarded until after 2016 for

future clinical development and research uses.

Design Statement

Site Context contd

Topography

The main development site covers a surface area of 23.7 hectares and is

approximately 700m long by 400m wide.

The site is largely flat, rising slightly to the southeast, and lies at approximately

15m above sea level. The London - Cambridge railway line runs at roughly

the same level as the site and is separated from the site by a low post and

wire fence and shallow ditch. The line has overhead power lines supported

on steel gantries.

A surface water drainage ditch and adjacent public footpath runs east -

west across the middle of the site and the path continues across the railway

line via an unmaned crossing.

To the south of the site the land rises to 40-45m forming the northeastern

promontory of the chalk Gog Magog hills further to the southeast.

The Hobson’s Brook corridor runs north - south in the agricultural lands

between the railway line and Trumpington to the west.

Climate

Sunlight

Cambridgeshire is a sunny county and the average hours of daily sunshine

in July 2005 were 4.7hrs, varying from 0 to a maximum of 15hrs. For

January the average was 2.5hrs varying from 0 - 6hrs.

In January 2005 average sunrise was 0810hr and sunset 1600hr. In July

2005 average sunrise was 0445hr and sunset 2120hr.

Temperature

Cambridgeshire, in comparison to other parts of the UK is cooler in winter

and warmer in summer. Temperatures in 2005 varied between -5 and 10C

in February and 12 and 32C in July.

Relative humidity

Relative humidity in 2005 varied from 23% in June to a maximum of 100%

in January 2005.

Rainfall

Rainfall in Cambridgeshire is relatively low generally and lowest through

November to August. The daily highest rainfall is in autumn with an average

for October 2005 of 5.6mm, varying from 0 - 45mm maximum.

Wind

Cambridgeshire can be windy and the highest wind speeds occur in

January. For 2005 daily recorded speeds varied from a minimum of 0 to

31 knots, with gusts up to 65 knots. The calmest month is July where 2005

wind speeds did not exceed 15 knots, with gusts of 40 knots maximum.

Design Statement

Landscape Context

The main development site lies within an immediate context, to its west

and south, of low lying expanses of arable fields with few hedges and

occasional copses and small woodlands adjacent to existing watercourses,

ditches and field boundaries.

To the west is the Hobson’s Brook and green corridor which sits within the

Green Belt. The Brook is not a natural watercourse and was created in 1614

to carry drinking water from the chalk springs at Nine Wells into Cambridge.

The Brook is an important ecological feature and wildlife corridor and is

designated as a City Wildlife Site.

The development site is presently cultivated as arable agricultural land.

The northern boundary is defined by a row of mature tall trees that screen

the school complex from view. Immediately beyond this tree belt are the

grassed external recreational spaces of the school. A long tree belt partially

screens the school from the railway.

A row of mature trees runs southwards along the western edge of Robinson

Way as far as the new Elective Care Centre.

There is low vegetation on the southern boundary, allowing open views to

the south - southwest. Beyond this boundary to the south is the Nine Wells

Local Nature Reserve.

A drainage ditch presently bisects the site from west to east. This ditch

is approximately 1.5m deep with banked sides and collects the main

surface water outfall from the existing Addenbrooke’s hospital campus and

discharges to Hobson’s Brook.

Objectives

• To develop world leading clinical research and treatment facilities that

stimulate and support patient treatment and recovery.

• To offer a unique and high quality destination for businesses with the

emphasis on research and development.

• To present a range of building sizes and configurations, ensuring

maximum flexibility for local/ regional occupiers with the potential to

attract significant inward investors.

• To create a high quality setting that is compatible with its surroundings.

• To deliver a development that follows the principles of sustainable

development within commercial parameters.

• To produce a high quality landscape within which the proposed new

buildings are to be set, with a high degree of accessibility and an

integrated solution for stormwater runoff.

• To offer on-site management and ancillary retail and cafe facilities as

amenities for the use and enjoyment of occupiers and their visitors.

• To provide employment opportunities to the wider area.

6.0 The Brief

Plot and Building Sizes

It is a central requirement of the scheme that as wide a range as possible

of clinical, research & development applications should be accommodated

within a group of buildings whose treatment, orientation and organisation

evolve from a coherent masterplan approach. The infrastructure and public

realm should be capable of being planned to offer a number of different plot

configurations and building sizes.

It is anticipated that the Medical Research Council will develop a new

facility on a plot at the northwest of the development for a new Laboratory

of Molecular Biology. Papworth NHS Foundation Trust, the specialist

cardiothoracic hospital have also recently announced plans to construct

a new facility within the development, although funding and the exact

requirements in terms of size and location have still to be finalised.

The remaining areas of the main development should be flexible to

accommodate a wide range of size and configuration options to meet the

requirements of future users.

It is envisaged that building will range in size from 3,000 sqm to in excess

of 30,000 sqm reflecting the bespoke nature of the proposed buildings.

A range of masterplan solutions have been considered to ensure these

building sizes can be satisfactorily accommodated.



25

Design Statement

Building Forms

The planned uses of the buildings will influence the building forms and

it is important to understand the impact on floorplate depth and building

heights at this outline masterplanning stage. The following building form

characteristics will inform the Masterplan layout:

• Clinical space will be designed in accordance with operational need.

• For research and development facilities, 18 to 27m deep modular

floorplates, with a combination of laboratory and write-up functions.

Benching layouts and the need for disabled access often determine a

laboratory module of 3.3m and a potential structural grid of 6.6m. Typical

laboratory plans are illustrated opposite. Presently there is a trend in

laboratory planning away from rigid enclosed structures to more flexible

open-plan layouts for less intense or sensitive/containment laboratory

activities.

Floorplates may - as suggested opposite - be planned around central

atria which can house break-out and social interaction spaces.

• R&D and clinical facilities will have enhanced servicing requirements

accommodated in deeper floor zones or possibly dedicated interstitial

service floors. Central plantrooms will also be large whether located on

the roof or elsewhere in the buildings. Floor to floor heights are likely to

be of the order of 4 to 7 metres depending on the specific nature ot theuser.

• R&D facilities will have greater security requirements when compared

with more traditional employment environments.

• The new developments will also accommodate administrative and office

based functions that support biotech R&D activities. These may be

planned in floorplate depths of 15 to 18m and may also be organised

around central atria.

Design Statement

The Brief contd

Land Use Allocation

The location of land uses has been determined by a combination of factors

including the neighbouring uses and the approved wording within the Local

Plan. Key factors have included:

• The need for clinical research and treatment buildings to be located

close to the Elective Care Centre so that they can readily connect viaa 3 level link to the existing hospital campus.

• The Papworth Hospital requirement is not yet confirmed but

may be as much as 45,000sqm of gross floor space. The Land Use

Allocation strategy will need to be flexible to accommodate such a

significant requirement, and a central zone has been identified on the

diagram opposite that could be developed for research or clinical

facilities, depending on Papworth’s operational requirements.

• MRC’s preference to locate on a self contained site.

• The need to include a significant amount of public realm.

• The desire to include a limited amount of ancillary amenity space

within the development to accommodate such uses as retail/

restaurant facilities and a management suite.

• The requirement for a new primary substation located in close

proximity to the new buildings.

These factors have informed the land use allocation as set out opposite.




28

7.0 Development Opportunities

Proposed Movement Axes

The principal future access points for vehicles and guided bus suggest two

primary on-site public realm routes or axes:

1. South - North

Connecting the proposed Addenbrooke’s Access Road with a link from

Robinson Way

2. West - East

Along the line of the proposed CGB route connecting the development

with Keith Day Road. It is proposed that this axis will be developed to

provide an important and contiguous public realm link between the CBC

expansion site and the existing hospital. A second west-east link along

the southern boundary will also provide a further link into the existing

campus.

Landscape

There are opportunities to protect, draw example from and extend the

immediate landscape context into the Site, to help assimilate the new

Development into it’s surroundings. These include opportunities to:

• Create a landscaped tree belt along the railway line boundary

• Protect and enhance the landscape/tree belt to the north and northeast of

the site along the Long Road College and Robinson Way boundaries.• Extention of the landscape belt/ buffer treatment to help assimilate

and mitigate the effect of the embankments of the proposed CGB and

Addenbrooke’s Access Road. The embankments will be up to 8m in

height and will have a significant spatial impact on the site.

• Strengthen existing connections with public realm spaces, such as Keith

Day Road, with formal landscape treatment to link the existing campus

and new development and create appealing external spaces that are

enjoyable to use at all times of year.

• Provide more open and lower level landscape treatment to the southern

boundary in order to maximise the pleasant views to the Nine Wells

Nature Reserve and Gog Magog Hills to the south.

• Mitigate the visual impact of the proposed substation.

10.0 Masterplan Options

Figure 22 - Illustrative Masterplan A

Figure 22 shows the masterplan concept which has been selected for

appraisal developed into an Illustrative Masterplan Layout. This layout

demonstrates how the expansion of the Cambridge Biomedical Campus

may be planned to provide a mix of building sizes - accommodating

biomedical research and clinical activities - coherently organised around

the key public realm spaces.

The Layout illustrates only one planning permutation. The central masterplan

concept of a robust framework of key public realm spaces allows flexibility

for different building and plot options (to suit specific research or clinical

requirements) within a single, legible, robust urban solution.

The Masterplan layout addresses a number of key relationships:

• Between private development plots and the common public realm.

• Between the scheme and its immediate context.

• Between the new development and existing campus.

• Between new clinical developments and the existing internal hospital

link corridor.

• Between proposed and existing modes of travel.

Design Statement

Flexibility

The scope for flexibility within the masterplan allows for a wide degree of

variation within later stages of development on the site. In order to explore

this, a Masterplan Variant (B) has been prepared, looking at how fewer,

larger buildings could be accommodated if end user needs - either clinical

or R&D - require this.

In essence, the plan shows the potential for substantial flexibility within the

parameters and demonstrates the potential to accommodate significantly

larger complexes without disturbing the central urban concept of the

campus.

Importantly, key elements, notably the boulevard, circus, piazza and set-

backs will be retained in any variant of the masterplan.

Figure 24 - Il lustrative area schedule for Masterplan A Figure 25 - Il lustrat ive Plot Layout for Masterplan A

The illustrative Development Areas diagram adjacent indicates the individual

development plots that are available after provision for access infrastructure

and structural landscape.

It is important to recognise that boundaries between plots are flexible, in

order to allow for specific user requirements to be taken up without creating

dead areas within the emerging scheme.

The key features of the plot development strategy are summarised as

follows:

Plot 1 is reserved for Clinical applications that relate directly to the existing

hospital clinical facilities. The intention is for the existing internal circulation

spine that connects existing facilities to be extended into this plot on 3

levels.

Plot 2 is anticipated to be the first plot to be developed, accommodating a

building of 32,000sqm gross floor area. It is currently proposed that this site

will be occupied by the Medical Research Council.

Plot 3 is located adjacent to the existing campus allowing it to accommodate

denser development. This may require decked parking. It will attract additional

design controls to ensure a positive relationship between buildings and the

key public realm space to the south.

Plots 4 to 14 could be combined into larger development sites if necessary

or alternatively could follow different configurations, depending on specific

user requirements. With this in mind, the inter-plot boundaries are considered

to be flexible.

‘R’ on the diagram adjacent refers to restaurant/retail/management suite

amenity facilities.

The southernmost plots will attract buildings requiring particular architectural

merit in their design.

39

Design Statement

12.0 Massing Strategy

The Massing Strategy sets out the overall principles which will deternine the

building configuration and orientation of the scheme.

The following features have contributed to the formation of the urban

proposal:

• The new MRC development will form a key early component of the

proposals, presenting a focus to views along the ‘Boulevard’.

• The height of development is to be graded up in scale towards the 5

-storey Elective Care Centre and existing hospital main buildings.

• Buildings fronting the central Circus and the Piazza are to be increased

in height and density to create a character of urban containment to

these key public realm spaces. This increase in height and containment

with a facade ribbon is echoed in proposals by the Hospital Trust for a

Learning and Development Centre on the north side of the Piazza.

• Building frontages and entrances onto the ‘Boulevard’ are proposed to

be organised in a consistent urban rhythm.

• Buildings in the western part of the site are to be oriented to highlight

the frontage of the scheme to rail users. Building volumes are not

continuous - in order to create permeability and openness.

• Buildings along the southern boundary are to respond sensitively to

potential views from the Gog Magog Hills.

• The central amenity and management Centre, possibly with a small

retail and restaurant element, is proposed to be developed as an

independent single storey pavilion located in the Circus.

Figure 26 - View from northwest - Illustrative Masterplan A





40

Infrastructure and on-plot drainage systems are to be developed in line with

the ideals of sustainable development. Wherever possible, combinations

of drainage features will be employed to provide a Sustainable Drainage

System (SuDS) for the scheme.

For reasons of sustainability, it is not recommended that extensive

ornamental water bodies are introduced. Smaller, optional features at

plot entrances and possibly in the Circus and Piazza public realm may be

considered.

Surface water drainage methods should take account of quantity, quality

and amenity issues and in particular:

▪ Manage run-off flow rates, reducing the impact of urbanisation on

flooding

▪ Protect or enhance water quality

▪ Be sympathetic to the environmental setting and the needs of the

local community

▪ Provide a habitat for wildlife in urban watercourses

▪ Encourage natural groundwater recharge

The requirement for SuDS extends to both the common areas and on

plot development in a total system approach. An integrated surface water

strategy that could be utilised is set-out in the diagram opposite.

The primary means of storm water attenuation will be through on plot water

storage and slow infiltration features with a discharge rate that should not

exceed 3 litres per second per developed hectare. A storm event of 1 in 100

years plus climate change is to be used for the storage design.

13.0 Surface Water Strategy

Figure 28 - Illustrative option for surface water strategy

Design Statement



41

Design Statement

Attenuation of surface water run off from infrastructure roads and hard

surfaces is to be acheived through the introduction of a system of channels

or ditches alongside the Boulevard. Pipes from kerb drains will discharge

to existing watercourses that will allow limited local infiltration of rainwater

into the subsoil (depending upon seasonal water table fluctuations) and

discharge remaining water along their course to balancing ponds at the

north and south of the Site. The overflow from these ponds discharges to

watercourses that eventually discharge into Hobson’s Brook.

In addition to these ponds, further basins will be provided for surface water

attenuation from the Access Road, to attenuate surface water run-off from

the CGB embankments (these may take the form of widened ditches) and

may also attenuate water run-off from the MRC roofs and hard external

surfaces.

Balancing ponds are to be located adjacent to the CGB embankment in

the north and the Access Road embankment in the south, as indicated on

the diagram opposite. These basins/ponds will store water at the ground

surface, either as temporary flooding of dry basins or permanent ponds.

On-plot surface water attenuation measures may include a high proportion of

permeable paving surfaces combined with an infiltration, or lined retention,

sub-base to parking and pedestrian areas, with overflow to a perimeter ditch

that discharges to the existing outfall ditches. Alternatively a proprietary

perimeter ‘Permachannel’ kerb may be considered in combination with a

lined ‘Permavoid’ tank sub-base below (impermeable) paving with overflow

as above.

The water channels and balancing ponds offer many landscape design

benefits and add value as a recreational amenity. Opportunities for the

provision of wildlife habitats around these features should be developed.

The principle aim of the public realm and landscape strategy is to create a

high quality public setting for development that creates an identifiable sense

of place and presents a positive impression of the site at all stages of the

development process. This will be supported by a commitment to provide

a high quality, well-connected public realm, characterised by contemporary

hardscape finishes and furniture, mature planting and a programme of

public art for international, national and local artists.

A combination of landform, planting and water will divide the site into

individual environments linked by pedestrian and cycle routes.

The attenuation of surface water will be a defining element in the landscape

of the Biomedical Campus and the surface water strategy outlined on the

previous pages will inform the landscape strategy in the public realm.

The elements and objectives of the Landscape Strategy are set out in the

diagram opposite and described below.

Overview

Boulevard

The main spine road through the R&D quarter, presented as a high quality

frontage to buildings through the use of upgraded hardscape materials,

semi-mature trees, sensitive lighting and a gabion retained swale surface

water course.

Circus and Piazza

A major new sequence of public spaces, framed by buildings with active

frontages and forming the key link between the existing and new parts of

the campus. It will be a route for pedestrians, cyclists and the CGB with only

limited vehicular access. The Circus will be a contained, landscaped space

for relaxation and interaction at the heart of the Development. The Piazza

will form an important link between the existing and proposed development

14.0 Public Realm and Landscape Strategy




44

and is intended to extend into the existing campus when the new learning

centre is developed.

Southern Spine Road

The southern spine road linking clinical plots to the new Addenbrooke’s

Access Road and the existing hospital campus. Landscape treatment will

need to anticipate the future development of the ‘Safeguarded Land’ (see

p9). The Southern Spine road will have a swale on its northern edge as

shown in Figure 34.

CGB Embankment

In general the CGB Embankment will consist of grassed banks. Details of

the landscape proposals are contained in the CGB Transport and Work

Acts Order. See also Figure 32.

Boundary to railway line

It is proposed that the boundary be planted as described below. Theboundary will include security fencing and a Sustainable Urban Drainage

System, such as a Swale, in order to accommodate surface water run-off.

as shown in Figure 33.

Planting

The landscape strategy envisages the creation of a broad framework of

native planting that is compatible with its context whilst contributing to the

reduction of visual impact.

Boundary planting treatment will help to establish the character of the

development, as well as accommodating storm water management devices

and providing a visual amenity to be enjoyed by staff, patients, occupiers

and the local community.

The buffer planting to the boundaries of the Development, will consist of

Illustrative example of buffer treatment to railway line

Illustrative example of planting to car park areas




45

small native trees (45cm - 60cm high at time of planting) planted at 1 per

metre. The perimeter planting will consist of mixed deciduous species with

the long-term intention of creating an oak, ash, beech mix which is the

natural vegetation of the region. 50% of this mix will be feathered trees

to give variety in height and form whilst the planting develops. Additional

species will be planted in the under storey and at the edge of the plantation.

This type of planting forms a mass, which will provide shelter to pedestrian

routes as well as acting as a background setting to the main development

areas, without compromising safety. Where good quality existing trees occur

on the perimeter of the site, they will be integrated into woodland structure

blocks. Generally structure planting will be carried out during development

so that the landscape setting is provided both in a timely and cost-effective

manner. Mounding and/or planting may be utilised to guide pedestrian

movement and create visual variety within the Development site.

Hardscape

A key consideration in the creation of a high quality campus environmentis the provision of a pallette of consistent and well designed hardscape

products. These extend from the choice of paving materials for roads,

cycleways and pedestrian routes to the lighting, signing and site furniture

products that will animate the proposed environment.

Illustrative examples of swale treatment

Key public realm spaces

The Boulevard

A number of visual, ecological and security considerations have informed

the design for the Boulevard.

This main circulation spine is planned to present the appearance of a

generous, high quality, formal Boulevard.The design provides an atypical

approach to the landscape treatment of new development and aims to unify

and harmonise the proposed buildings, SuDs, pedestrian and vehicular

access treatments whilst offering ecological potential.

A double tree lined space is proposed, providing a sense of continuity, uniting

the different elements within the site and connecting the new development

with the existing hospital.

SuDs and Swale design

A formed swale or channel is planned either side of the Boulevard. This

will receive and conduit surface water run off from the road and footpath

surfaces to attenuation basins at the north and south of the Site. A naturalised

vegetated treatment is proposed for the swale which connects the site to

it’s surrounding context. The swale feature mimics the ditches and brooks

(such as Hobson’s Brook) that are characteristic of the local landscape.

The plot side of the swale channel is to be retained in a vertical incline with a

stone filled gabion cage system. This provides a cost effective, naturalistic

method of clearly delineating the transition between private and public

space. This transition is further defined by a hedge which acts as a visual

and physical barrier.




48

The gabion cage can be filled with stone that is sourced from the locality

and reflects the local vernacular.

The swale slope on the road side will be planted with low maintenance

naturalistic, marginal vegetation to accommodate changing water levels.

The flat sections of grass adjacent to the road and footpaths will be close

mown grass.

In accordance with Health and Safety guidance the slopes of the swale are

no steeper than a gradient of 1:2.5 to allow for ease of maintenance and

egress. The hedge also provides a protected edge by preventing access to

the swale from the plot side.

Planting

The double tree lined avenue of semi mature trees (20-25cm girth on

planting) will create continuity, provide aesthetic appeal, shade, shelter and

habitat for wildlife. Indigenous, hardy and rapid growing species offeringvisual interest such as Alnus spaethii (Alder) will be used.

Height at time of planting approx 5-6m.

Height after 10 years approx 15m.

Hedges will be trimmed to 1m in height to afford unobstructed views from

within the buildings.

The swale slope will be planted with low maintenance naturalistic, marginal

vegetation to accommodate changing water levels. The flat sections of

grass adjacent to the road and footpaths will be close mown grass.

The Southern Spine Road

The Southern Spine Road forms the principal access to the clinical areas

and is proposed to have a similar landscape form to the Boulevard (see

section p44). A swale channel and avenue of trees is proposed along

it’s northern edge. The grass verge and hedgerow to the southern edge

anticipates future development in the Safeguarded Land to the south.

The Circus and Piazza

The design for the circus and Piazza aims to provide connected, areas of

Public Realm that will:

• Create a high quality centre to the development.

• Accommodate a variety of uses including areas for relaxation, bus stop

for the CGB and an amenity building.

• Reflect the microclimate and seasonal fluctuations.

• Facilitate movement between buildings.

• Provide a route for the CGB.

• Create a safe, attractive and pedestrian friendly environment.

The Circus

The Circus is envisaged as a large circulation space that facilitates the

movement of people between buildings, the Boulevard and the CGB. It is

designed to provide an attractive, high quality outdoor environment where

people can stop, eat and relax. The flexible landscape design provides the

opportunity for outdoor seating arrangements and the promotion of café

culture.

A variety of landscape features and visual stimuli are proposed. These

could include water features which can act as striking and stimulating focal

points. The Circus also provides a natural focus for the provision of public

art.

Sculptural elevated grassed areas could be used to add variety and providean alternative space in which to relax.

Surface detailing such as the choice of pavers, their colour, texture and

design layout serve to unify the elements and direct movement within the

Circus and connect with the Piazza and Boulevard.

The Piazza

The Piazza will form a key element of the public realm, connecting the new

and existing developments. The intention is to adopt a shared strategy for

the new development with that proposed by the Hospital Trust for the area

outside the proposed learning centre and hotel.

The Piazza is defined by a bold design of simple forms to provide a strong

sense of identity, whilst remaining cohesive. There are strong design and

detail references to the Circus and Boulevard, for example double linear

avenues of trees, choice and pattern of surface materials and style of street

furniture.

As per the Circus, the Piazza is designed to facilitate the flow of pedestrians

in an aesthetically pleasing environment. The double tree avenues are

located on the sunnier northern side offering a degree of shading to ground

floor levels. The trees are arranged in blocks with seating. This provides

a mix of sheltered and non sheltered spaces; full sun or dappled shadeand the opportunity to spend time within the spaces. The southern more

shaded side of the Piazza is narrower, serving a more directional purpose

incorporating the route of the CGB.

It is proposed that the surfaces are at a continuous level to allow for un-

interrupted movement. Again, surface detailing such as the choice of

pavers, their colour, texture and design layout serve to unify the buildings

either side of the Piazza, delineate space and direct movement.

53


The Circus & Piazza

Hardscape

To ensure the Circus and Piazza are visually connected, similar materials

are to be used throughout their design. Definition of spaces and delineation

occurs through colour and texture change. High quality materials are

used throughout the design that relate to the choice of building materials

proposed and the style and function of the architecture. Crossover, rumble

strips and entrance areas would be surfaced with conservation cobbles or

block pavers.

Furniture and lighting

The design aims to integrate street furniture and lighting within the overall

structure and layout of the space;

• to reduce un-necessary street clutter

• to provide multi-functional items

• provide pedestrian friendly level lighting

• allow the Circus and Piazza to be functional spaces at night

Planting

The bold blocks of trees that utilise the sunny side of the site connect the

length of the Piazza with the Circus and mimic the planting of the Boulevard.

The trees are arranged in regular, sculptural blocks, which cast a dappled

shade onto the paving and reflect light back onto the ground. The blocks of

trees provide a vertical element that unifies the different scales of the tall

building forms with that of the Piazza pedestrian level.

Trees well suited to the local soil type would be used with a preference for

species which require little moisture and with shallow rooting, to enable

planting near buildings.The Betula utilis Jacquemontii (Himalayan Birch)

would be a good example of the type of tree that could be used

The trees of the Circus and Piazza will form part of a series of green corridors

that permeate the site and benefit wildlife.

Figure 40 - Parameter Plan - Road access strategy

15.0 Access Strategy

An important part of the development’s success will be providing a

coherent and effective transport strategy. Further information is provided

within the Transport Assessment which has been included in the planning

applications.

Roads

Vehicular access to Addenbrooke’s will be improved through the provision

of the Addenbrooke’s Access Road that will link the campus with Hauxton

Road to the west and provide access to the strategic road network to the

south and east, including the M11 & A10. This road, which will cross the

rail tracks to the south of the proposed development site, will be delivered

following a programme that will relate to the opening of the new R&D

campus.

The proposed road will connect with the existing road network serving the

Addenbrooke’s campus via the new Boulevard.

Whilst vehicular access to the proposed campus will be permitted from

the north and east, via Robinson Way and through the existing campus,

measures are to be introduced which will prevent rat-running and congestion

by vehicles that are not accessing the wider campus.

The proposed new roads are to be built to adoptable standards and will

be a maximum of 7.3 metres in width. Where appropriate, and where road

speeds are restricted, cycleways will be brought onto the road surface for

local access.

It is proposed that the Boulevard through the R&D element of the scheme

should be finished in upgraded materials, such as specialist kerbs, block

paving and proprietary street lighting, in order to produce a high quality

public realm.

Design Statement



55

Cycleways

Cycle access will be a key feature of the future movement strategy and

cycle lanes will be provided in association with the proposed Addenbrooke’s

Access Road and adjacent to the proposed CGB route. Cycle movement

on the site itself is to be achieved through the on-site distributors except

where a dedicated cycleway is provided. Improvements will be made to

the broader cycling network and the scheme aims to advance opportunities

for safe on-site cycle movement with the provision of dedicated cycleways

associated with the CGB route and the Access Road that connect with the

adjacent cycle network.

In particular, links with the National Cycle Route 11 from Great Shelford

adjacent to the railway tracks will be delivered.

On-site provision for cyclists will link with the existing and future off-site

provision, with the aim of endorsing the scheme’s sustainable development

credentials and ensuring that a safe, year-round solution is delivered asearly as possible in the implementation process. The future marketing

strategy for the scheme will emphasise the opportunity presented by the

cycle access solution.

Cycle storage will be provided in close proximity with the entrances of the

proposed buildings. Provision is to be made on each development plot with

a target ratio of 1 space per 120sqm of development for staff parking and

an additional 1 space per 600sqm for visitor parking.

Figure 41 - Parameter Plan - Cycle access strategy




56

Figure 42 - Parameter Plan - Pedestrian access strategy

Footpaths

This diagram shows the proposed pedestrian movement strategy. High

quality pedestrian access is an important objective and the aim at the

Cambridge Biomedical Campus is to provide an attractive, accessible and

safe environment. Pavements on either side of the principal on-site road

will be supplemented with independent links to the west and east, giving

access to the leisure and retail facilities located in Trumpington and at the

heart of the existing campus, and to the south, where permissive footpaths

link into the broader countryside.

The Circus core of the site will be developed as a recreation resource in the

form of a central public space. This will serve as an attractive destination for

staff, patients and visitors, particularly in the summer months, and a primary

and safe link with the existing campus for everyone.

The following key features are included in the footpath access strategy:

• Existing perimeter pavements on Robinson Way will continue to functionas elements of the highway network.

• On-site footpaths associated with proposed new roads are to be

developed to adoptable standards.

• The potential for legible east - west connections between the core of the

scheme and the proposed housing to the west will be exploited.

• The creation of a pedestrian oriented environment linking into the

existing campus primarily through the Circus and Piazza.

• The proposed Circus will be developed as a leisure resource which will

be accessible to all occupiers and visitors.

• The footpath network will be easily accessible to everyone including

those with disabilities

Public Transport

A key principle for the design of the Biomedical campus is the creation of

an inclusive environment that can be used and enjoyed by all, regardless

of gender, disability, age or special need. Well connected, accessible public

transport is a key aspect of inclusive design.

The diagram right shows the Public Transport Access Strategy for the

proposed campus and its linkages with the strategic and local networks.

The scheme will be supported by a spur from the planned CGB route that

will link Trumpington Park & Ride and the centre of Cambridge with the

campus. This will provide a dedicated and regular service to link with rail,

bus and parking services and a CGB stop is proposed to be located in the

central Circus space.

The CGB will be routed through the development and the existing clinical

campus. A stop will be provided on the Piazza, the CGB will then continue

to the Addenbrooke’s bus station, the exact route on the site will be agreedbetween the Trust and the CGB operators. Wherever possible within the

development, the CGB route will use traffic free or lightly trafficked routes.

In addition, existing bus services along Robinson Way will be diverted

through the extended Campus to the on-site bus station at the Hills Road

entrance, stopping at existing and additional bus stops on the campus.

It is currently envisaged that there will be three bus stops within the new

development, two additional and one to replace an existing stop. Additional

services will be developed to cater for demand as part of the Travel Plan.

Access Strategy contd

Figure 43 - Parameter Plan - Public transport access strategy

Vehicle Parking

The parking strategy for the Biomedical Campus has been developed in

line with Cambridge City Council’s current parking standards as set out in

Appendix C of the Cambridge Local Plan and to reflect the overall aims of

the Travel Plan ‘Access to Addenbrooke’s’.

The parking strategies for the Campus are set out in the ‘Parking Strategy’

incorporated in the separate Transport Assessment prepared by Faber

Maunsell.

Broadly, parking for staff working in the biomedical and biotech research

facilities is to be planned to the rear - screened by buildings from the public

realm spaces. Generally, parking for these facilities is to be planned at

grade, although more densely developed plots may require decked parking

solutions. Up to 10% of the parking spaces - principally for disabled people

and visitors - may be located to the f ront of buildings along the Boulevard.

Provision of spaces for disabled people and access from these spaces to

the buildings is to be in accordance with the Disability Discrimination Act.

In accordance with Cambridge City Council’s parking standards, 5% of the

total number of parking spaces should be provided for disabled people.

Patient, visitor and staff parking for clinical buildings is likely to require

some multi level decked areas and will be located to provide safe and easy

access to the facilities.

16.0 Parking Strategy

Cycle Parking

Cycle parking will wherever possible be covered and located close to

building access points to the rear of buildings. Short stay cycle parking for

visitors should be provided at the fronts of buildings and within the Circus

and Piazza.

Delivery Vehicles

Delivery areas and ancillary refuse enclosures for buildings will be planned

to the rear of buildings screened from the public realm spaces

It is an inherent feature of the masterplan concept that there should be a

number of ways in which the scheme could evolve. This will ensure that,

for as long as possible, there is scope to accomodate as wide a range of

building sizes as possible. This includes the potential for a major complex

and/or user. The phasing strategy, shown right, is therefore only an indica-

tive solution.

The phasing of the biomedical and biotechnology research buildings will

follow market demand but the general aim will be to locate new development

adjacent to previous phases. The scheme is expected to be initiated in the

northern part of the site with the new MRC facility likely to form the first

phase of development.

It is intended that the north - south Boulevard and associated infrastructure

and planting will be constructed in the first phase.

The construction of the clinical buildings in the southeast section of the

Development will be phased according to clinical needs.

Where appropriate, consideration will be given in plot and building design to

address possible future expansion. Expansion or extension designs should

blend with the original plot design concept in terms of layout, massing and

materials.

A high quality landscape setting is to be provided in association with each

phase of development. This will occur in close association with the building,

access road and infrastructure that is to be delivered with each phase.

Generally, parking will be provided concurrently with the phase they are

to serve, although some additional shared parking may be provided in the

short term.

Set Backs and Building Orientation

The diagram opposite sets out the desired building orientations, building

lines and key accent points within the Masterplan. Buildings on individual

plots are to be orientated and aligned to reinforce the urban spaces and are

to comply with the following guidance:

▪ Buildings on plots either side of the Boulevard are to be set-out with their

principal volumes parallel or perpendicular to the line of the Piazza.

▪ A notional building line is established set-back 16m from the Boulevard

kerb. Part of building frontages should be set-out on this line.

▪ Principal volumes of buildings either side of the northern swept section

of the Boulevard, may be set out radially, or parallel/perpendicular to the

southern section of the Avenue.

▪ Buildings on plots around the Circus are to be set-out to establish an

urban containment to this space.

▪ Clinical and research buildings on plots to the east of the Circus are

likely to be set-out with their principal volumes parallel or perpendicular

to the Boulevard and - in part - aligned with adjacent buildings to the

east. Exact orientation and set-out of clinical buildings will depend upon

operational requirements.

▪ Clinical buildings along the southern boundary are to be set-out with

their principal volumes parallel or perpendicular to the Southern Spine

Road. A notional building line is established set-back 28m from this

road kerb. If buildings are to be constructed close to this boundary, then

building frontages should be orientated to this line.

The following set-back guidelines relating to the perimeter of plots are also

to be incorporated:

▪ 5m landscape screening zone to west and north boundary of the

Development site.

▪ 15m building set-back from west and north boundary. Note that some

plots may need to accommodate infrastructure services routings. Where

possible these will be located within this 15m set-back zone. The 10m

zone between the landscape screening and building set-back may be

used for surface car parking.

▪ Buildings are to be set back from inter-plot boundaries by a minimum

of 8m. Link structures - for example between clinical buildings - can

bridge plot boundaries to improve access. There is scope for buildings

with associated uses to be located more closely together if there are

particular reasons for doing so.

Vistas and Urban Accents

Buildings are to respond both to views into the Development and vistas

along infrastructure roads within the Development. The following guidelines

are to be incorporated in on-plot design:

▪ The west facing elevations of plots to the west of the Boulevard should

present a frontage to the London - Cambridge rail line that projects the

status of the Development as an international centre of research and

clinical excellence. Building volumes should be configured to create an

interrupted and permeable facade line.

▪ The building on the plot to the extreme south of the Development - visible

from the London - Cambridge rail line and new Addenbrooke’s Access

Road - is to be architecturally expressed as a gateway building.

▪ The building on the plot to the north of the swept section of the Boulevard

is to create a termination for the vista from south to north along the

Boulevard.

Figure 46 - Illustrative setbacks, building orientation and urban accents




66

Figure 47 - Parameter Plan - Maximum building heights and

maximum envelope

Building Massing and Height

Building heights will be graded across the site, with generally lower buildings

located towards the western and southern boundaries and higher buildings

located towards the eastern boundary and the existing Addenbrooke’s

buildings.

Figure 47 sets-out maximum heights for buildings across the new

Development.

▪ Building heights will be no higher than 36m including roof level plant (if

required) but excluding flues, above ground level towards the existing

hospital. This could be interpreted as 6 floors + 6m plant at 5m floor to

floor or a maximum of 4 floors if interstitial service floors are required.

▪ Building heights will be a maximum of 31m closer to the southern

and western boundaries with the exception of the area immediately

adjacent to the existing campus where 36 metre building heights may

be appropriate.

▪ Roof level plant including flues and outlets is to be integrated into the

overall building design. Either by setting-back plantrooms from the

roof edge or integrating into a solution for the massing/elevation of the

building.

▪ The treatment of plant on buildings on the western and southern

perimeter of the site should recognise the sensitivity of views into this

part of the scheme.

▪ Main frontages should be emphasised and front entrances in particular

marked by the massing solution and enhanced by the use of appropriate

external materials and soft landscape.

▪ Where possible frontages to the building lines set out should be of a

significant height (within the maximum height constraints) to acheive a

perception of containment to the infrastructure public realm.

Note that the controlling height line of a building will be the parapet line or

eaves of the top of the building or plantroom, allowing flues and vent stacks

to extend above this line.

Elevational Treatment

The aspiration is for a strong contemporary architectural identity for the new

Development.

The urban infrastructure will establish a robust framework within which

there is scope for creative architectural expression on individual plots. The

intention is ‘coherence without conformity’ and architectural designs for

individual buildings should contribute towards a unified spatial effect across

the whole biomedical campus.

Elevation proposals are to develop from integrated architectural solutions

that seek to express the progressive uses of the buildings. Leading edge

structural and envelope technologies in addition to technological solutions

that seek to reduce environmental load are to be promoted.

Building elevations to clinical and research spaces are to have a horizontal

proportion and modulation. Long elevations should be articulated with

vertical elements.

Where possible transparency should be introduced in facades - allowing

life within buildings to animate the public realm. Specific areas of buildings,

particularly in clinical buildings, may require higher levels of visual privacy

and physical security, but staff break-out and vertical circulation areas are

an opportunity to open buildings up and draw visual connection between

building interiors and exterior spaces.

Elevational treatment should seek where possible to integrate with the new

buildings on adjacent sites to the east such as Cancer Research UK and

the Elective Care Centre buildings.

Building Materials

Criteria for selection of building materials should include:

▪ Contemporary, elegant

▪ Tested

▪ Durable, low maintenance

▪ Colours generally neutral tones with accent colour if appropriate

▪ Clear (but high performance) glazing

▪ Neat, carefully detailed junctions between components

Servicing and Ancillary Buildings

On-plot Security & Amenity buildings, sub-stations, plant enclosures,

motorcycle and cycle storage and other ancillary structures are to

be designed to integrate with the overall landscape and architectural

proposals. These structures should be located, where possible, to the rear

of buildings.

Illustrative examples of elevational treatment




68

On Plot Landscape Design Guidelines

A key consideration is the delineation of public and private space. Whilst

privacy and security should be maintained, the private space should not

feel isolated. This requires careful attention to the choice of hardscape

and softscape detailing that defines different spaces and their functions

whilst maintaining a connection. On plot spaces, whether public or private

should facilitate harmonious movement and circulation of pedestrians,

cyclists and vehicles. The proposed secondary public spaces within plots

should be clearly defined, easily accessible, versatile and provide facilities

for stopping and sitting. Careful landscape design should aim to enhance

comfort, taking account of microclimatic conditions on plot.

Plot frontages

Treatment of plot frontages will be formal in nature. In these more visually

controlled areas, amenity is the main function of the planting whilst retaining

visibility for security purposes. The main requirements for internal on-plot

planting for building frontages are highlighted below.

Planting

Landscape buffer/mitigation requirements between plots will be provided

within the boundaries of the plots. Planting shall be no higher than 1m

within 1m of a highway/footpath or within sight lines. If directly adjacent

to a footpath or cyclepath the plants will not be thorny species. Planting

should take account of microclimatic conditions on plot, providing a choice

of shaded and non shaded areas. Planting between the secondary public

spaces would be required to have some conformity in order to provide a

sense of connectivity across the site. A mix of deciduous and native plants

should be used.

Ground cover planting up to 1.2m high, combined with a minimum of

advanced nursery stock trees (clear stemmed up to 1.8m), is the preferredIllustrative treatments to plot frontages

69

approach to planting in formal situations, in order to maintain sight lines and

psychological safety for pedestrians.

Similarly, medium and large shrubs, where provided, will be spot planted as

specimens. Large areas of shrub cover should be avoided, because these

can cause security problems and harbour anti-social behaviour.

Proposals that comply with the adjacent Boulevard and Southern Spine

Road planting will be used to unify the frontages of the development plotsand also compliment the visual impact of building elevations to the roads.

Hedge planting around parking areas and on the edge of the Boulevard

will be grown to circa 1 metre height to reduce the foreground view from

the roads, but with due regard to security issues (i.e. preventing possible

concealment).

The clinical areas to the south will be treated as a single plot in terms of

planting and landscaping unless there are operational reasons for internal

segregation of different activities or specialisms.

Car Park Planting

It is important to control the appearance of car parking areas and make

adequate landscape provision otherwise the setting of buildings deteriorates

and the quality of building architecture diminishes. Car parks are to be

ordered, have well defined edges, be easy to use and provide safe and

comfortable routes to buildings.

Where appropriate, surface car parks will be enclosed with a hedge

and perimeter tree planting. Within each car park linear tree planting in

combination with hedges is proposed to reduce the visual impact of parked

cars and also to provide shelter for pedestrians. The hedging should also be

used to fragment larger parking areas into compartments. Where possible

these hedges should be aligned with those on adjoining plots.

Illustrative example of buffer planting

Illustrative example of planting to car parks

Car parking in clinical areas is expected generally to be multi-storey except

for a limited amount of operational and disabled spaces which will be

provided close to the entrances of buildings.



Design Statement




71

Ecology

The ecological and habitat potential of landscape proposals will be an

important consideration in the selection of appropriate design solutions.

Species of plants will be chosen according to their wildlife benefits and

native and locally-sourced species will predominantly be used, which will

provide enhanced foraging areas.

Bat boxes will be provided on trees around the site and House Sparrow

boxes and nesting features for other birds will be provided on some of the

buildings and trees in suitable undisturbed areas around the development.

Permanent lighting will be directed away from the boundaries, wooded

areas and acquatic habitats to reduce disturbance to bats.

In providing sustainable urban drainage systems special consideration will

be given to habitat creation.

A Construction Environmental Management Plan (CEMP) will be compiled

prior to works commencing on site to ensure best environmental working

practice during construction.



Design Statement

Appendix - Design Guidelines contd



73

Contractors will be required to maintain the environmental risk register

and put forward a method statement committing themselves and sub-

contractors to the following sustainable construction measures:

▪ Waste minimisation - excavation arisings, material/component

packaging, re-usable shuttering

▪ Minimise pollution - noise, particle, contaminants

▪ Minimise energy use associated with transportation and on site

machine equipment▪ Waste segregation, reuse and recycling.

▪ Contractor training programme to promote environmental awareness

and best practice.

Occupiers will also need to respond to the Sustainable Energy requirements

set-out in the Cambridge City Council redeposit Local Plan and in their

Sustainable Development Guidelines. For example this requires evidence

of minimised energy consumption or the incorporation of on-site renewable

energy (that will provide 10% of energy requirements).

Surface Water

Infrastructure and on-plot drainage systems are to be developed in line

with the ideals of sustainable development and combinations of drainage

features are to be employed to provide a Sustainable Drainage System

(SuDS) for the scheme.

The principle components of the Surface Water Strategy are set out in the

diagram on p38.

The primary means of storm water attenuation will be achieved through on

site water storage and slow infiltration features with a discharge rate that

should not exceed 3 litres per second per developed hectare. A storm event

of 1 in 100 years is to be used for the storage design.

Attenuation of surface water run off from infrastructure roads and hard

surfaces is to be acheived through the introduction of an open ‘swale’

system of channels or ditches alongside the Boulevard as outlined on p45.

On-plot surface water attenuation measures may include a high proportion of

permeable paving surfaces combined with an infiltration, or lined retention,

sub-base to parking and pedestrian areas, with overflow to perimeter swales

or ditches. Alternatively a proprietary perimeter ‘Permachannel’ kerb may

be considered in combination with a lined ‘Permavoid’ tank sub-base below(impermeable) paving with overflow as above.
