Although Thom Mayne and his firm, Morphosis Architects, have designed several supertall buildings (towers more than 300 meters, or 984 feet high), Hanking Center is the first one to be constructed. The firm’s earlier 985-foot-tall curvilinear Phare Tower, in Paris, of 2010, and its hotel tower for Vals, Switzerland (1,250 feet), designed in 2015, are both, so to speak, 6 feet under. So it’s good to have the 1,148-foot-high Hanking Center office tower in the Nanshan district of west Shenzhen, China, actually realized and currently filling up with office tenants. The office has entered a competitive category where Mayne can nod nicely to KPF (which has four supertalls alone in Shenzhen) and other architects he encounters during invited interviews with prospective global clients.
