The Great Court at British Museum, Norman Foster

I went to this Great Court a couple times. It is surely a really comfortable space with lot of soft natural light. The structure is quite pretty. The repetition of its thin members do not dominate the roof, instead it creates a special effect, like a net on the sky, a nice one. However, the space is indeed quite small as there are just so many visitors.

The central quadrangle of the British Museum in London was redeveloped to become the Queen Elizabeth II Great Court, commonly referred to simply as the Great Court, during the late 1990s. It was opened by Queen Elizabeth II in 2000. The court has a tessellated glass roof by Foster and Partners (Architects) and Buro Happold (Engineers) covering the entire court and surrounds the original circular British Museum Reading Room in the centre, now a museum. It is the largest covered square in Europe. The glass and steel roof is made up of 1,656 pairs of glass windowpanes; each of a unique shape because of the undulating nature of the roof.
