The 10-storey egg-shaped home of the London Assembly and headquarters of the Greater London Authority.
A ramp, half a kilometer long, spirals up through the building, allowing Londoners to watch their Assembly members in action. It begins in the basement and ends in the exhibition/function room at the top of the building: the principle of accessability made manifest.
The shape of the building provides the greatest volume with the least surface area exposed to direct sunlight. Manually operated vents provide natural ventilation and cold groundwater is pumped throught the ceiling beams to provide cooling. All these contribute to the building's low energy consumption.
Each window is unique in shape: they were cut using laser technology.
Architect: Foster and Partners
