Willis Building London
This large modern development for the Willis headquarters occupies a prime site. Its striking 29-storey tower and the adjoining 10-storey building have glass exteriors (there are 3,771 windows) and together create an elegant stepped design. The "stepped" design was intended to resemble the shell of a crustacean. Winner of New City Architecture Award 2007.
