As the request of London County Council, the project included a widening of Knightsbridge, and the creation of a new dual-carriageway road beneath the building, named Edinburgh Gate after the Duke of Edinburgh, to provide access to Hyde Park, and also providing access to underground car parks.
The tower was lower than the skyscraper included in the original design, shortened during the planning process to reduce its visual impact when viewed from Hyde Park.
The building was clad with polished granite, brick and glass, creating approximately 25,000 square metres (270,000 sq ft) of floor space.
[1] Harold Samuel, founder and chairman of Land Securities, commissioned a sculpture from Jacob Epstein: his last sculpture Rush of Green (also known as The Bowater House Group, The Return of Spring, The Family, or The Pan Group) was completed shortly before his death in 1959 and installed in 1961 on a plinth separating the carriageways beneath the building.
[1] Some critics considered the building to be a good example of modernist architecture, but others thought it ugly, blocky, and too heavy for its location beside the junction of Knightsbridge and Sloane Street.
