As part of a large scale redevelopment scheme the center includes among other things swimming pools, gymnasia, squash courts, and a large shopping area. It was originally planned to be part of a larger system of raised walkways, adopting the Smithson’s idea of “streets in the sky”. The adjacent International House high rise is part of the project as well.
