The previous building, which was coming to the end of its useful life, was purchased by Kajima in the 1990s. Having reviewed a range of options, Kajima teamed up with Hammerson Plc to pursue an ambitious and comprehensive redevelopment. It was an intricate task involving underground tunnels, maintenance and improvement of the high level walkways around the nearby Museum of London, and the preservation and refurbishment of Plaisterers' Hall. The sinuous lines of the building reflect the site’s geometry and constraints, and make this a notable landmark in this part of the City.
