WOHA is a Singapore-based architecture practice, established in 1994 by Wong Mun Summ (born 18 August 1962) and Richard Hassell (born 28 October 1966). Its name is derived from the initial letters of the founders’ surnames. The form and appearance of WOHA’s architecture is always guided by the local context and culture, and above all, by the local climatic conditions, which determine every energy-saving strategy. In order to revitalise their urban environments, WOHA’s structures are designed to harmonise with and incorporate natural ecosystems, and to proactively encourage self-sufficient cities, which will have no need for the destructive use of artificial energy. They’re practice gravitates around sustainability.
