World Trade Center Rotterdam
Staal received this commission by winning a competition in 1928 also entered by J.J.P. Oud. The ultimate design, however, deviates radically from the competition scheme. A slender bell-tower and a meeting hall on stilts mark the entrance. The exchange hall of 90 x 60 metres is spanned by arched steel girders clad in concrete panels embedded with round glazed tiles. A gently curving glass bay window gives a wide view of the Coolsingel boulevard. During renovations the café on the plaza (Beursplein) and the meeting room of the Chamber of Commerce were restored to their original state. In 1986 the World Trade Center was erected above the hall of the Exchange.
