The German architecture firm Büro Ole Scheeren has been chosen to design the new global headquarters of the technology giant Tencent in Shenzhen, the so-called ‘Chinese Silicon Valley’. Under the title Tencent Helix, the German designers present a building with four towers emerging from a spiral-shaped base. According to the architects, the proposal symbolises the company’s rapid growth.
