London City Hall

Opening its doors back in 2002, the glass-fronted, semi-spherical London City Hall marked a new dawn of London’s governance, providing a sleek, modernist façade for the London Assembly. The building alone is impressive, a geometrical masterpiece designed by architect Sir Norman Foster (who also designed the nearby Gherkin) and featuring eco-friendly natural ventilation, lighting movement sensors and solar panelling, as well as a dramatic transparent spiral stairwell that dominates the interior and climbs all ten stories. 
The landmark building now not only serves as the official headquarters of the Mayor of London, but as a public exhibition and meeting space, including an open-air observation deck and free Wi-Fi to all visitors.
