Courtyard Housing Design competition, On-line exhibition Portland, Oregon, 2007

The ‘weaving’ concept creates a sustainable net of densely shared space. In housing environments the requirements of privacy and social interaction must be balanced so that a sense of individual ownership exists alongside neighbourhood security. External, internal and in-between spaces of housing units are continuous ‘threads’ of sharing possibilities.

Courtyard Housing Space is squeezed, twisted, shifted, and overlapped at the local scale of a unit and continues to intertwine at the global scale of plots. Individual characters of housing units are attained through tenants’ choices of materials and the locations of units in the system.Individual sharing space and housing units weave and tie together to form the ‘fabric of the scheme.

Two independent four-stories houses are united under one roof responding to concepts of extended family living. The two houses sit in a living compound with a newly renovated four-stories house and a new two-stories serviced building. The two houses are designed to have the same functional programmes with a shared large living area on the ground and first floors. Natural ventilation flows through the shared double-height space between the two houses which creates more view points, allows heat to escape and becomes a reference point that marks the start and the end of each house.

The west elevation acts as the ‘shield’ against the strong sun and noise from the common area of the housing estate. Future expansion of two more bedrooms can be incorporated within the shield toward the back of the house.

The orientation of the building is towards an ancient pyramid in the city. Design of apartments takes advantage of the orientation while answering to popular ‘loft’ lifestyle in Lima.The design of the building considers preserving order and vista corridor of neighbouring buildings on one side while introducing unusual mass at the corner of the urban block.The design offers varieties of room types both one-floor and two-floor apartments. All rooms have view to streets and the pyramid. 22 out of 28 units have direct and panoramic views toward the Inca shrine. The communal space on top of the building commands 360 degree view of the city.

Apartment-Loft building Inspired by the Inca shrine, the facade system is designed to lessen the noise and heat through its pyramidal shape.The gap between the ‘pyramidal skin’ and the living unit’s wall provides thermal insulation which circulates heat near the building surface upward as well as acting as sun shading device.

Evolutionary planning & Landmarks
Housing Estate Client: Hathairaj Estate 4.5m GBP, Master planning & Design development (Stage A - C) 135,000 sqm, Bangkok, 2004 The project is planned and designed for middle-upper income inhabitants. The site is located in the up-and-coming area of the city. The design of the master plan is influenced by space of real communities which have evolved over time. As a result, the estate contains rich spatial varieties in the shapes of land plots and spatial configurations of each living cluster. Each plot and each living cluster influences space of the next one. These qualities establish the uniqueness of the development and give the estate dynamic spatial sequences that promote the sense of belonging within and between communities.
Project cost calculated in Thai Baht according to local market cost models converted into GBP.

Housing Estate Six clusters of communities and common facilities are planned to be built in phases compatible to the investment plan and demands.The sizes and numbers of land plots available are guided by the feasible study which suggested two appropriate sizes: 240sqm (88 plots) and 400 sqm (107 plots).
E
Land plots at the corners are treated as prime spots where one-off bespoke house designs are offered. These corner spaces and architecture become landmarks which give special characters to the whole development in a similar way to the way squares and public buildings do for urban space.Road layout is also planned to integrate with further development to the north and west sides of the site. The final phase will use the land in front of the development for mixed-use and retail facilities which serve the communities in the estate and integrate with the existing urban fabric of commercial streets.
