Haesley Nine Bridges is a unique golf clubhouse in Yeoju, South Korea. Korean architect Kyeong Sik Yoon collaborated with Tokyo-based Shigeru Ban Architects to produce this extraordinary project. The building houses a restaurant, a bar and a wellness and spa area. The design brings together various influences from nature. The architectural concept for the roof construction was based on the geometric pattern of traditional Korean basketwork. The client wanted a spectacular clubhouse in the centre of their new 18-hole golf course. The entire roof construction is supported by 21 columns resembling tree trunks. The 15-metre-high columns extend over three storeys to the roof, which measures 36 x 72 m.
