00- introduction
Unit 22 Theme
DARE TO CARE. Architecture taking care of vulnerable realities.
Technification pushed us to hold to the illusion that humans are invulnerable, with our magnificentcreations, our cities and our technologies. This resulting system allows economic privilege and the shortsightednessof the economic sphere to overwhelm the ecological and social realities in which we all live.The advances of science and technology and the domination over nature, allows us to consider that our environmental worries are no longer about what nature might do to us, but what we are doing to nature. The modern world seems to harbour notions that we stand outside of nature, that we are notembedded in an ecology. Nevertheless newspapers and television remind us that we are far from controlling nature and preventing its risk productions.While natural hazards still pose a major threat, even in the developed world, and the new sort of self-produced risk has been spread all over, the result is that we are substantially more vulnerable.
We will measure the quality of architecture by its ability to represent the interest and programs of others, being these others, humans, non humans, institutions or any other aspects and entities of our. BRUNO LATOUR
Including the ecological limits and dependence of everything we design. Protecting the context from the damage we are creating using the logic of Solving for pattern, coined by Berry in his essay of the same title, as the process of finding solutions that solve multiple problems, while minimizing the creation of new problems and maximizing the amount of opportunities- WENDEL BERRY

Lancashire is a North Western English County. It emerged during the Industrial Revolution as a major commercial and industrial region. The county encompassed several hundred mill towns and collieries. By the 1830s, approximately 85% of all cotton manufactured worldwide was processed in the Lancashire area.
19th century has seen the area shrink much smaller following a major reform of local government. The boroughs of Liverpool, Knowsley, St Helens and Sefton were removed entirely from Lancashire.
By the census of 1971 the population of Lancashire (including all its associated county boroughs) had reached 5,129,416, making it then the most populous geographic county in the UK. The administrative county of Lancashire was also the most populous of its type outside of London, with a population of 2,280,359 in 1961. On 1 April 1974, under the Local Government Act 1972, the administrative county of Lancashire was abolished, as were the county boroughs. The urbanised southern part largely became part of two new metropolitan counties. The south-western part became part of Merseyside, the south-eastern part was incorporated into Greater Manchester.Lancaster has become the most urbanised county yet its diminished size and appearance is one of countryside and abundance of land. Its demise of mills has lead to mostly retailers and quarries as its main economic and residents remain large. Agriculture although still present is by far exceeded in economic output by industry.

Site is a 2.5 acre plot on the outskirts of Halton, North West England. It runs alongside the river Lune, and is 3.4 miles away from Lancaster town centre. It is easily navigated by bike and car. Historically, it was a site for an engineering company Luneside Engineering and in 1950 they built mechanical life size elephants which they took on tour around the country. Before this there were several mills on the site for cotton, linseed, fabrics before the businesses ceased and the properties sold. These mills did use the water from the river nearer the eastern end to use in ponds and building processes. It now houses one out of use old mill building.

Housing and public shared facilities for Lancaster Co-housing Group. There will be approximately 32 households comprising of houses 1-3 bed, houses and studio units. There will also be common facilities for sharing and preparing food. Laundry, visitors housing, car pooling and other activities will be shared within the scheme. The emphasis on the project is about food sustainability and general sustainable living. Appreciating where food comes from and the enjoyment of the experience of eating as a social past time. Due to time and money constraints, the inhabitant will move in at an earlier stage than completion and alter their surroundings themselves for their communal spaces in which the building will grow slowly.
- list of matters to be addressed
1. Architecture will respond to the different layers of private to public spaces that residents will encounter between the communal to the bedroom spaces and encourage interaction between people.2. The architecture will improve the relationship between the eater and the history of his/her food.The experience and enjoyment of eating will be drawn upon with the appreciation of where it has come from. 3. Architecture will respect and preserve the natural environment that it is housed in.5. The workings of architectural systems will be made obvious to its users in a friendly and understandable way.

Intentions:
Aims to improve food quality that is the dietary value, and the enjoyment value as a community and social activity by providing a scheme for living, growing and providing. By being mindful of the surroundings and the existing nature cycles that we are part of, the intention will be to add to and improve these systems of food waste, cooking, food production and by doing this having more of a connection with where our food comes from. Even though the feeling of these communities are old fashioned, the scheme should bring out its modern in attitude and outlook. It should set an example of a new and successful way of living, socialising with the community around you and to have an appreciation of the surroundings. It should promote social activity between all families, races and ages but also respect the privacy of individual households and members of the community that may not live on the premises.
It should be open to all as a way of living, and the process of adjusting to this way of life should be as easy and natural as possible.
Motivations:
Slow food as a link between land and food.To build a link between living and eating in set of building systems which treat the two activities as an engaging and dependent of each other. Treating nature not as an all mighty all beautiful object to admire, but as a delicate and almost dangerous world in which to be part of needs close attention to the systems already taking place in it. Therefor the architecture will try to preserve the land as much as possible. Symbiotic relationship between the processes of people, animals and plants. The slow food attitude extends to that of the environment- to protect it as it provides us with nutritional value that we must not destroy. As all the waste products from cooking, cleaning, packaging, heating will have an effect on the surroundings, which will in turn have an effect on the land which provides us food, The motivation of this project is not just to produce a eco village but to set en example of the quality of living and feeding ourselves and the environment well.
Food sufficiency in the way of production, cooking and waste produced must be dealt with to fit into the local environment and not to pollute it. Many normal species of plants may pollute the river which can have dramatic
problems on the habitat of the river animals and plants. This is true about foreign water also. So, there will be a motivation to produce a set of systems which will benefit the surroundings not add to the problem.
Slow architecture
The building will develop over time according to the needs and desires of the residents. Since as a community they get on well and like to be really involved with their surroundings, the architecture will reflect their interests and elements of craft.
Some households being responsible for certain areas of the common facilities will allow people to take ownership of the activities while sharing the facilities with others. It will therefore encourage people to look after shared spaces and encourage socialising.

For comfortable sharing eating experience3 flats are clustered to make as few variations possible to make it cheaper/easier to build. Also these eating spaces could be combined larger parties i.e for a group. See next column.
A joint number of clustersgrouped according to program here access to everyone but of more responsibility of the group
These extra communal spaces willbe arranged according to what cluster is appropriate. eg. Energy is needed for running of computersand rainwater is needed for showers.

There is a distinction between the different layers of space in which the program and space is organised. This means that in the co housing scheme there is a maximum amount of interaction between residents while they carry out different activities. The journey of a resident from their individual house to their choice of activity or to leave the building will be one of many transitions between these spaces.

Crumbling rock faces made of sandstone and limestone- integral to landscape but not good for growing on
Massing model on site. In this general form the housing is dense instead of sprawled to impact of the ground as little as possible.
It is proposed that the ground should be brought back to a more natural state which will encourage native plants and animals to use it as well as provide a natural floor on which to live on.
However, the ground is not stable and there is in need of a retaining wall to the north side of the site where a rock face is crumbling.
There are many animals that live on the site, and the building should not destroy and if anything help to provide the habitat in which they thrive.
The river is a source of water, and the south side of the site is largely unobstructed to beautiful views across the River Lune.

DESIGN REALISATION- TOWARDS A SLOW FOOD CO-HOUSING TYPOLOGY CLARISSA YEE UNIT 22 13
SUN:South facing windows will take advantage of winter and summer sunlight and also provide view out to the Lune.
The arrangement relies on most of the houses to be lit from the north and south sides with limited windows on the east and west side which are harder to have solar control over
Also, with planting occuring on the site, the best way to grow vegetables is arguably in rows north to south with the taller plants like tomatoes and beans to the north and the shorter or imbedded plants to the south so that they do not shade each other. The trees of the site also provide solar shading when the sun is low in the sky in the summer afternoons but not so much in the winter when the trees lose their leaves.
WIND:Wind is strong and in a south westerly direction. According to the Lancashire Council Web site, this site has the potential or wind energy capabilities.
WATER:Water runoff is naturally from north to south heading towards the river. This movement could be taken advantage of to collect rainwater for flushing toilets, planting and washing.

[Academic use only]
Construction program option 1 taking into account that the community will want to move in as soon as it is possible this method would mean that the community would have to wait until the end of all of the construction
Construction program option 2. The community would move in after each zone of building is completed. The growth of the architecture by the community is more organic. They will learn as they go along and be part of the excitement of the build.

01.34 Structure Detail
In order for the building to grow, the formwork for the rammed earth construction could be attached to the timber platforms itself as a guide and a base to stand on while doing the upper part of the ramming.
Jet grounding is a good alternative to concrete, as it is less intrusive in the soil and takes advantage of using the soil itself to stabilise the structure above it rather than having to dig out the ground and pouring concrete. Jet grounding also is a process which has less embodied energy than in situ concrete.
It could be fixed to the timber posts using a high strength motar. *

01.35 Structure Analysis Overall
Section analysis shows that using the jet grouting method, there is no need for cross bracing the timber structure as there is no rotation movement at base. This is due to the very rigid mortar joint at the base of the columns. The jet grouting base resists the movement of the wind in all directions for the length of the post so other structural elements are not required. This is opposed to a typical connection at footing which does not resist rotation at base. *

01.36 Structure Analysis Foundations
[Academic use only]
Gravity loads from live weight and dead weight are carried through the load bearing timber columns. The jet grouting covers a large area within the ground to act as friction between it and the soil to counterbalance the weight of the building. (Section A)
Each column is fixed centrally to a jet grouting column to evenly distribute the weight. The fixing between the timber column and the jet grouting resists reactions of the wind in all directions due to the steel bars and high resistance mortar for a rigid connection at the base. (Section B)
Jet grouting at base of column doubles as viewing platform and seating

01.40 Services Strategy
[Academic use only]
Risers which will carry all services for water and electricity etc will be for each individual cluster as shown in the diagram. Each riser will then serve that cluster for these needs.
These will be accessible by riser cupboards which when needed to in the future can be used to additionally plumb extra services for new spaces in which it is adjacent to,
The diagram shows in yellow how this could be done in the additional spaces. *

01.41 Explanations and Precedents
The infrastructure and the framework sets where the bedroom units will be in location of the plan.
When the residents move in there is the infrastructure to support the way the building grows to their needs.
A good precedent is the Social Housing Project by Elemental where the bathrooms and bedrooms were built first leaving gaps where the residents would build out the extensions to their houses when they could afford to do so. This gives great flexibility and control to the users of the building.

01.50 Access
Building Regulations Part M states that means of access to and into a dwelling should be reasonable provision within the boundary of the plot of the dwelling for a disabled person to approach and gain access into the dwelling from the point of alighting a vehicle which maybe inside or outside the plot. In most circumstanced it should be possible to provide a level or ramped approach.
However due to the variations in topography on steeply sloping plots mean that a stepped approach would be reasonable.
This will satisfy part M1 of the Building Regulations since:-Stair widths are greater than 900mm-Rise of flights are less than 1.8m-Intermediate landings are less than 900mm in length-The treads have suitable nosings and the rise of each step is 150mm -There is a suitable handrail at least on one side of the flight.- Level entrance from vehicle to staircase-The entrance door has the appropriate door width of minimum clear opening of 775mm.-All corridors exceed minimum widths for disabled access.
Common Stairs has been provided for access between storeys designed to suit the needs of ambulant disabled people which is compliant with Part M of the Building Regulations.
WC is provided within the entrance storey of the dwelling which can accommodate a wheelchair user.The door opens outwards and provides a clear space for wheelchair users to access it.
There is a passenger lift that satisfies part M with 1500mm by 1500mm clear landing in front of the entrance and doors of which has a clear opening of 800mm minimum

01.60 Fire
In the event of fire, there will be a suitable means of escape which will allow a safe exit from the building by all occupants. Fire strategies will be compliant with Part B of the UK building regulations. The nearest fire station from the site is 3 miles away in Halton, so the building must be fireproofed to allow enough time for the fire and rescue service to reach the building.
Fire risks are higher in residential buildings more than any other type of building, and risk of fire may occur by:
Cooking and kitchen fireResidents fireElectrical fireForest fire
Building regulations Part B has guidance on means of warning and escape in event of fire.- there is sufficient means for giving early warning of fire for persons in the building.-there are routes of sufficient number and capacity which are suitably located to enable persons to escape to a place of safety in the event of fire; and - the routes are sufficiently protected from the effects of fire where necessary.

01.61 Fire Analysis
As the building is on a slope it makes sense that people of the top floors will be safer to escape to the road side north of the site, and the people on the lower floors of the site will be safer to escape to the south side of the site by the banks of the river. This could be a problem as if may cause confusion for residents knowing which exit is best for them.
Here the diagram shows on the ground floor the strategy is that people have access to the circulation space which is 30min fire rating to which the staircases can be accessed for escape.Walls between houses in semi detached houses or houses in terraces should be treated as separate buildings and therefore dividing walls will be treated as compartment walls which form a complete barrier to fire. They should also run the full height of the building in a continuous vertical plane and continue through the roof space. If one beam, joist or rafter fails it has been designed so that is will not cause failure in any other compartment.

01.70- Context- local planning policy and unitary development plans
Areas of outstanding beautyScope For Increase Woodland CoverConservation areas
The site (marked by the red X) exists between an area of outstanding beauty and conservation areas. It also is in an area for scope for Increased Woodland cover.
The site was originally paved over so by removing this tarmac and allowing the ground to revert back to its original state and the foundations of the building to be kept light the ground is actually improved through the scheme. Also, the opportunity for increased native wildlife in the area can be accommodated within the scheme.
Relevant Policies and Strategies cover:
Sustainable communitiesRegenerate the local economyRegenerate the local environmentLandscape Character
The scheme exists within the local planning policies by addressing the concerns about the landscape and the sustainability of the scheme. In the choice of passive systems, and material choices of the project. Addressing the energy use and the environmental systems that have been chosen. Also in the protecting the natural habitat of the native animals and plants on the site. *

01.80 Acoustic qualities
The site is relatively quiet with no problems of sound pollution or traffic due to the site. However, with the site becoming residency for a small community with lots of interaction between them there is a concern that there needs to be acoustic control between rooms especially between residents private rooms and communal rooms. It will be up to the residents to choose and add acoustic barriers to control the acoustic qualities of their spaces. The use cork, sheep wool and rammed earth are choices in which can be added by the community and readily as needed. *
1.90 Health and Safety in construction
The build will be over 300 man hours for the timber construction so appropriate CDM regulations will apply. A CDM coordinator is required.
There is also a need for safety in the third stage of construction for when the community adds to the building. There will be a need for some members of the community to learn the techniques correctly and to carry out the construction safely. **
