The Canary Hall or the city hall is regarded to be London’s most up-to-the-minute buildings of London. The famous architect Norman Foster designed the City Hall & it was situated on the South bank of the Thames River which is near the Tower Bridge. The work was completed in July 2002. The modern architecture was not well-liked by all. According to them who disliked the structure described this City Hall as a misshapen egg, a motorcycle helmet & an onion. But according to the designers they chose this bulbous shaped structure because it would reduce the surface area & also would be energy efficient.
This building is a part of complex & it concludes shops, offices & a gaunt amphitheatre. This theatre makes this hall to be a centre for cultural practices because during the summer time certain open air concerts are held in here. The initial noticeable thing is the helical walkway which measures about 500 meters (1,640 feet) and ascends from the bottom all the way to the top of the building, which measures 10 stories tall. The top of the ramp is a large exhibition hall known as “London’s Living Room”, which is sometimes opened to the public. In addition, solar panels and natural ventilation were installed on the roof to reduce electrical consumption, making City Hall one of London’s “greenest” buildings.
