model of international tourism complex, hangzhou, china by steven holl architects

steven holl architects has been awarded first prize in the design competition to redevelop
the site of the oxygen and boiler plants in hangzhou,china.

the master plan includes residential towers and an international urban exposition center,
and integrates functions like an art gallery, restaurants, and performance and exhibition spaces.
the scheme, based on the concept of shan-shui, meaning mountain and water, builds on
hangzhou’s relationship with west lake. at the heart of the bow-tie plan is an earth and water
tower, which act as a vertical gathering of the water and mountain zone. from this central
position in the large site, one tower branches north towards tributary forms approaching the
oxygen sector while the other branches south toward landscape forms at the boiler sector.
the north half of the plan is characterized by a new zone of recreational waterstrips, offering a
variety of housing types, and lantern towers, which take inspiration from the old stone lanterns
in west lake. setting 'fire over water,' photovoltaic glass curtain walls gather the sun’s energy
during the day, while at night one elevation of each tower glows, reflecting the day’s energy
in the water.

in the south plan, a tilted landform of natural grasses is punctured for light. hovering over
a large public water garden, the structure is a dodecahedron truss, which contains a hotel,
restaurants and cafes.

within the minimally restored shells of the oxygen and boiler plants, new experimental
architectural forms designed by a variety of artists and architects, take on the functions of cafes,
bars, and exhibit or performance spaces, and allow for a flexible programmatic plan, which
can take adjustments over time.
