MASTER PLAN / URBAN DESIGN CONCEPTS
The Housing District West at Punggol has been envisaged to be a new benchmark for housing development in Singapore. The uniqueness of the site is the creation of the Punggol Waterway and hence the emphasis of the relationship between development and water. The mapping and reading of the master plan is multivalent rather than hierarchical. The architecture, public spaces, connective tissues and movement systems are dispersed across a series of interpenetrating green connectors that weaves across the site to facilitate bridging to the waterway. There are two major elements in our design: visual connections and eco linkages. These elements are superimposed on a pre-determined general layout of major road networks and water infrastructure. The superimposition generates a sequence of interstitial spaces suggesting fluid movements and connections to various parts of the development.
Visual ConnectionThe entire Housing District West is designed and developed as a whole based on generating vistas open towards MRT/LRT stations, water and communal nodes. By emphasizing direct visual connections, the entire site establishes strong relationship with its surrounding context. Distinct places are created which could be easily identified and differentiated from one another. Each communal node is different in terms of its form and levels. Visual axis are created to enable way finding from wherever location throughout the site. Key visual connections are from communal nodes to LRT/MRT stations, community node to communal node and communal nodes to the waterway. These connections enable one to position him/herself within the site in relation to its surroundings. The visual connection between one communal node to another also enlarges the perceptible dimension of each park within its own precinct and thus add to the qualitative experience of the public domain.
Eco LinkagesThe entire Housing District West was looked at as a potential large green lung in line with HDB’s idea of ‘Green Living by the Waters’. The housing quarters are composed of series of linear buildings twisted to form clusters that enclose major public spaces within the site. The clustering of the residential blocks enhances sense of community as well as privacy at the same time. These individual precinct parks will then be connected to each other by means of eco pathways. These landscaped pathways meandering through the entire site to form a continuous ecological structure. Within each precinct, the landscaped platforms are flexible, reacting to site conditions. These platforms vary in width to accommodate different public activities. They are programmed with sports, leisure playing fields and playgrounds. Everywhere one goes, the qualities of a green housing district can be felt due to the dynamic arrangement of building blocks that resulted in a very porous environment within each plot. The criss-crossing of broad paths and trails takes one past a series of courts, lawns and a range of recreational activities. The creation of the E Deck within each precinct also means that car parking is kept below the platforms to make way for an uninterrupted and safe pedestrian network above.
With the merging of green, water and residential, Housing District West will be an area that has strong unique identity and conducive for living. It is a synthesis of approach focusing on the ideas of connection and bridging; interaction and interrelation of ordering systems; and integration of natural systems of green and water with the built environment.
HOUSING DESIGN SCHEMES
The buildings are designed with sustainability and flexibility in mind. With the ever increasing demand of the end users, a lot of consideration is taken into account in order to produce a good design that is both aesthetically pleasing and functionally practical at the same time.
Building Orientation
Most of the building blocks are oriented along the East-West axis wherever possible in order to exploit the full potential of the waterfront site. This orientation also helps in solar shading of the building blocks and thus reducing the need for artificial cooling.
Building Massing
The buildings were deliberately designed to have different heights in order to avoid the whole scheme being read as series of monotonous concrete walls throughout the entire site. Those blocks that are closer or fronting the waterway are intentionally designed as low rise buildings which will then create a more human scale streetscape along the promenade. To make up for the required density, maximum number of units are stacked up at those blocks located at the deepest end of the site furthest away from the waterway. This configuration allows for views towards the waterway for most of the blocks including those at the back.
Views and Identity
The linear blocks are meticulously shifted and twisted in order to allow maximum number of dwelling units having views towards the waterway as well as Sungai Punggol. The twisting form of the buildings give the much needed identity to each block so as to avoid rigid and ‘faceless’ architecture. Residents will be able to identify their home by the form of the buildings instead of merely rely on block number signage on the walls.
Green Roof
Planting on roof surfaces acts as thermal barrier for the top floor units creating a cooler environment.
Thermal BarrierInsulated west facing gable end walls increase U-Value thus keeping homes cool, reducing the need and energy load for air-conditioning.
Natural Ventilation
Units are pulled apart allowing prevailing North-South winds to keep the corridors cool and naturally lighted.
Modular SizingDimensions of structural elements are standardized together with use of precast elements for efficiency.
Reconfiguration PossibilitiesThe unit floor plans are designed to suit various residents’ needs. Structural clarity and standardization are emphasized to enable flexibility in rearrangement. Columns and shear walls are kept at the periphery with all the intermediate walls being partition. This allows for the intermediate walls to be omitted or added at ease.
