SHA win design competition for redevelopment plans in China 

An international nine-member jury including Thom Mayne, Wolf D. Prix, Ralph Lerner and Terence Riley have announced that Steven Holl Architects have taken first place in a competition centred around the redevelopment of oxygen and boiler plants in Hangzhou, China. Herzog & de Meuron took second place and David Chipperfield Architects took third.

This master plan includes residential towers and an international urban exposition centre at Hangzhou Urban Planning Documentation Center, and also integrates functions such as 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 characterised 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 functions of cafes, bars, and exhibit or performance spaces, and allow for a flexible programmatic plan which can take adjustments over time.
