In 1988 Regalian Properties purchased the site, and appointed Terry Farrell as architect. Farrell designed a self-contained community of shops, housing, offices and public spaces for the site. Regalian disliked the proposals and requested Farrell design a single large office block. Despite containing 50% more office space than the rejected Green Giant proposal, the design was accepted. The government then bought the site and design as a future headquarters for the Secret Intelligence Service, and the design was accordingly modified to increase security. In 1995 the SIS Building was opened on the site, and today dominates other buildings in the vicinity of the bridge.
