At 1km high, Phoenix Towers for HuaYan Group in Wuhan, The City of a Thousand Lakes, will be the world’s tallest pair of towers, a landmark within an ambitious environmental master plan for Wuhan, the capital of central China. The project is one of four master plans Chetwoods are developing with HuaYan in the region. The Phoenix Towers incorporate design and technological features developed in the course of Chetwoods’ self-funded research projects and competition winning schemes such as an inhabited London Bridge for The Worshipful Company of Chartered Architects and The Royal Institute of British Architects. Their innovative technological features and symbiotic relationship will work to recycle and clean water and air to actively contribute to a reduction in local pollution. The towers cover seven hectares of a 47 hectare site, situated on an island in a lake, which is at the end of a 3km avenue within a dense city layout.
