CONTENT
INTRODUCTION
In the module of Architectural Studio 5, I designed a community library in the heart of the humid tropical metropolis of Kuala Lumpur. The site is a narrow strip of land right next to an old shopping street.
The proposed library has an estimated area of 1200 square metres and is 5 stories tall excluding its roof garden.
Its design aims to tackle two major issues of the site, namely the demand for an education centre and lack of greenery. Thus, the design focuses on softscape and vernacular elements.
As for this module, we are to propose a roof system and two alternative façade designs.
PROJECT NAME:
VERTICAL PARK LIBRARY
SITE: JALAN TUANKU ABDUL
RAHMAN, KUALA LUMPUR
COCOON HOUSE, VIETNAM
Architects: Ta Tien Vinh and Truong Tuan Chung
ADVANTAGES & DISADVANTAGES
REASON FOR SELECTION
Advantages:
Simple to prefabricate and build, promising rapid construction
Great flexibility to customization and design
High thermal mass, providing cooling effect to building interior
Allows maximum ventilation
Ease of maintenance
Disadvantages:
Smaller and higher number of components
Repetitive work during construction
Application of vent blocks adapts the building to its tropical context by maximizing cross ventilation throughout its façade. It too gives a sense of privacy as well as ample shading from sun and rain.
Ventilation blocks are a trend in tropical regions due to its aesthetics and functionality. It has a long history as a traditional building module in areas with hot climate as they provide climatic comfort and protection.
FAÇADE PRECEDENT STUDY 1
This house is renovated from an older building that is narrow and clustered. The old balconies at both ends of
the house were skinned with precast concrete ventilation blocks. Two varieties of vent blocks alternate
randomly with the patterned one at higher frequency. The space inside the skin was left for rain, wind and
sunlight to pass through. Its design is inspired from a cocoon, where the expressive façade allows access to
nature but with security and privacy considerations.
MATERIALS USED
Precast concrete ventilation blocks, Cement mortar
METHOD OF
CONSTRUCTION
Concrete blocks are precast and sent to site. The blocks are then laid onto one another with cement mortar as adhesive component.

LE NOUVEL, KUALA LUMPUR
Architect: Jean Nouvel
ADVANTAGES & DISADVANTAGES
REASON FOR SELECTION
Advantages:
Reduces noise level within building
Provides insulation, thus decreasing air-conditioning requirement
Improved air quality
Visually pleasing and soothing Disadvantages:
Requires costly nutrient, pruning and irrigation equipment
High maintenance and construction cost
The design of Vertical Park Library holds the principle of resurrecting nature to the site, which needs more shade and greenery. A green wall forms a barrier between the library’s interior and its chaotic surrounding, hence improving its sound and air quality. Covering a façade with flora gives a positive psychological impact to pedestrians of the dystopian, heavily-urbanized site which lacks tranquil softscape.
Situated right next to KLCC, Le Nouvel is a dual-tower luxury residence with a façade integrating lush tropical greenery into a heavily urbanized context. Its façade is a combination of vertical rectangular aluminum posts and horizontal cable rods that allow vines to grow onto it. Planter boxes are placed irregularly between the posts.
The typology of this façade falls under ‘indirect system with planter boxes’. Climber plants are kept away from the walls by cable supporters. The cable system suits faster growing plants with denser foliage. As time progresses, the growing plants will cover the façade entirely.
FAÇADE PRECEDENT STUDY 2
MATERIALS USED
Cable rod, Rectangular hollow steel post, Aluminum planter boxes, Creeper and flowering plants, Fertile soil
(soil, peat and sand in the ratio 7:3:2 by volume)
METHOD OF CONSTRUCTION
The system is made up of the following components: containers, insulated containers, maintenance remote automated irrigation and fertilization systems, and wall mounting system. Tensile cable rods extend from permanent vertical steel beams. Plants grow from planter boxes, covering the façade.

EPIC HOMES (THROUGHOUT MALAYSIA)
Architect: Ben Phua
ADVANTAGES & DISADVANTAGES
REASON FOR SELECTION
Advantages:
Allowing passive design ventilation as air flows freely through the gaps between timber planks
Simple and lightweight for construction
Rapid construction and lower costs due to prefabrication
Wooden floors do not retain much heat nor conduct heat
Disadvantages:
Susceptible to fire as they lose strength at high temperatures
Prone to corrosion at marine environments
The houses’ design is suitable for tropical climates similar to our current site. It drew inspiration from traditional Malay attap houses by standing on stilts, allowing cool air to enter below via gaps between timber planks and hot air to be removed from the top of the house. The theme for Vertical Park Library emphasizes on vernacular architecture and living lightly on the site. Timber does not retain heat, decreasing heat gain of the building. Simple steel structures are conventional and readily-available, thus cost and time efficient.
FLOOR PRECEDENT STUDY 1
Specially designed for ease of assemble and rapid construction, EPIC homes are modular houses built throughout
Malaysia for the needy in remote areas. Its steel post and beam structural design with wooden floor finishing is
lightweight and portable, making it efficient to build.
METHOD OF CONSTRUCTION
The floor structure is made up of
beams that extend from columns
with brackets at intervals. The
secondary structure, which are
timber beams, are locked in these
brackets. Wooden planks are then
nailed onto the timber beams
beneath.
MATERIALS USED
Hollow steel beams, Chengal timber beams, Chengal timber planks, Nails
Hardwood timber planks and beams
Steel beam with brackets
VILLA SANUR, BALI, INDONESIA
Architect: Paul Koodravsev
ADVANTAGES & DISADVANTAGES
REASON FOR SELECTION
Advantages:
Utilizes local, renewable materials
Inexpensive
Waterproof and weather resistant
Ideal for places with hot climates due to good insulation
Environment friendly as materials needed are grown and harvested with little machinery
Disadvantages:
Combustible if fire occurs
Labour intensive
Thatch is not a standard product, each roof will vary slightly
Thatched roofs have existed in our tropical country since its early history, thus best represents our indigenous heritage in architecture, which fits the library’s theme of reviving vernacular elements. Craftsmen and materials needed for its construction is easily available locally, making it sustainable and efficient.
ROOF PRECEDENT STUDY 1
Villa Sanur is a complex of small villas and verandahs with traditional thatched roofs scattered on a 24000 m2
site. Its approach is highly localized and vernacular, an interpretation of a traditional Balinese compound. Design
emphasis was placed upon the openness of living areas to the garden. Water was an integral part of the
landscape design and rare palm species are used. To fit its theme, its construction fully utilized locally-available
materials and craftsmanship. Thus, explaining the villa’s abundant use of thatched roofs.
MATERIALS USED
Nipa palm leaves, Bamboo, Manila rope, Timber beams and columns
METHOD OF
CONSTRUCTION
Bamboo rafters are tied to the
ridge and purlin members of the
roof. The ladder lashing
technique is used to attach the
dried palm leaves to the
bamboo rafters. A series of
knots were tied from one end to
another, zigzagging through the
rafters that keep the leaves
intact.

Façade entirely covered with prefabricated precast concrete
ventilation blocks, each attached to one another via cement
mortar. Metal plates extend from steel I-beams at each floor,
adding extra support to the repetitive blocks by countering
lateral forces.
