  • FLYING LANDHONG KONG PUBLIC HOUSING ON THE HILL

    Shortage of flat land in Hong Kong has resulted in a fantastical urban

    density as well as massive infrastructural engineering projects, such as

    the land reclaimation that supported the entire Sha Tin New Town. As the

    urbanism in Sha Tin has filled up the flat land from the reclamation over

    the past 30 years, the hill area surrounded Sha Tin valley becomes the

    possible candidate for future urban expansion. The project seeks to inno-

    vate means of construct a massive Hong Kong public housing estate in

    a challenging urban and natural context of Tai Wai North, Sha Tin, Hong

    Kong.

    TREND

    Over the years, both public and private estate are built denser. There has been no new HOS estate built after 2000.

    Shui Chuen O housing estate is a public housing estate. It includes18 residential towers, each with 25-30 stories, constructed on hills. All together it will provide 11,123 rental units and will be able to ac-commodate an population over 29,000 people. Shui Chuen O Plaza inside the estate have 59 retail spaces and an open market for rent. Shui Chuen O estate is connected to MTR station and Pok Hong Estate via pedestrian bridge and elevator tower. Public transportation hub and parking space are also constructed for the residents to com-mute. Completion of the entire estate is scheduled between the end of 2014 to the beginning of 2016 by phases.

    CONTEXTHOUSING ESTATES

    TAI WAI NORTH STATISTICS

    Housing estates in Hong Kong are well known for their outrageous den-sity and monstrous scale. The newest public housing estate in Sha Tin area, Shui Chuen O, contains more than 11,000 units and prepares to serve more than 29,000 people. Housing estates, especially those located outside of city center, are generally planned with a package of public amenities and commercial facilities to serve the population. Given that car ownership in Hong Kong is relatively low, planning of housing estate is very much dependent on MTR (Mass Transit Rail) and other public transportation while it is much less dependent on private vehicle access.

  • CONTEXTTAI WAI NORTH

    Tai Wai North is one of the earlier developed area in the entire new town of Sha Tin. Lo-cated at the southwestern end of the Sha Tin Valley, Tai Wai North is an important transpor-tation node with an MTR station serving two lines and two major highways and tunnels that connect Tai Wai North to rest of Sha Tin district and Hong Kong. At the heart of Tai Wai North is an urban village with 400 years of history.

    Located at the southwestern end of the Sha Tin Valley and the beginning of the cannal, Tai Wai North is an important transportation node. There is an MTR station serving two lines. And two major highways connect Tai Wai North to rest of Sha Tin district and Hong Kong through tunnels.

  • The popular tower+podium encloses pub-lic domain inside podium structure, which discourages public interaction and prioritiz-es individual private spaces over the public plane. By reversing the conventional spatial relationship between tower and podium, a whole new set of opportunities are created.

    TYPOLOGY

    Landscape in Tai Wai North is characterized by dramatic topographic shifts. There is hardly any flat surface that is necessary to serve a massive housing estate. Common approaches to create flat land have been disruptive to the natural landscape and unsustainable.

    ORIENTATION

    TO THE CITY

    Perpendicular orientation of the structure dramatizes the presence of the structure. As the structure steers away from the urban fabric, each tower has a different relation-ship to the urbanism in Sha Tin based on its distance to the city. By connecting the city at one end and the hill on the other, the entire structure carries urban infrastrcuture to the hill and lay out foundations for future development.

    The flat land in the air is inevitably an megastructure. Eight massive housing towers have a total of 10,108 units to house more than 22,000+ people. The ser-vice podium not only needs to accommodate com-mercial, public services, community programs like any other public housing estate in Hong Kong, but aslo needs space for traffic, loading, parking, and mechanical spaces, which normally goes onto the ground surface in other housing estates. Despite of its monumental scale, the structure is in fact com-parable to that of Festival City.

    The site is oriented perpendicularly to the existing urban development in Tai Wai North, connecting the city to the hill. It is situated inside the major valley next to the New Terrirtories Ring Road. A pedestrian drop-off is located at the feet of the towers. An additional connecting road on the hill is required to connect the podium for services.

    Pedestrian circulation is connected on both ends of the structure, while vehicular circulation that ser-vices the entire estate happens on the top of the podium in a cul-de-sac fashion.

    Landscape design is driven by the speed of travelling as well as minimal intervention on natural topogrphy. Traffic flow from both express lane and slow motion converge at the flat surface between towers to create a meeting area. The leisuire zone with plantations helps the estate bound-ary to blur into the natural landscape.
