HENN have won a competition to design a 450-metre tower for Haikou on the Chinese island of Hainan.

The tower forms part of a masterplan for the new business district that will include ten towers of between 150 and 450 metres.

The competition was won by Henn StudioB, the Berlin design and research studio of Henn Architekten. The same studio won a competition to masterplan the new business district for Wenzhou in November 2010.

HENN wins the first prize in the international competition to design the Haikou Tower in China.

Among the participants were Wilkinson Eyre, Broadway Malyan, Zaha Hadid Architects and RMJM/Alsop.
