The 40-story London headquarters of Swiss Re, completed in 2004, is even more unusual. Foster and Partners' conical tower has been nicknamed the Gherkin, although to me it looks more like a Jules Verne rocket ship. (There is a private dining room in the nose cone.) The circular plan and tapering cross-section reduce wind loads on the building and also decrease gusting at street level. The tower is divided into six-story sections, incorporating interior light wells and "sky gardens," which were first introduced at the Commerzbank. The result is not merely a striking building but also a more comfortable and energy-efficient work environment. Swiss Re is probably the most technologically advanced office tower in the world today.
