London Transport Headquarters 55 Broadway

Highly original stone clad steel framed office building straddling St James's Park station. Holden's building for London Underground's headquarters above St James' Park tube station. London Transport executive Frank Pick engaged Holden as architect for several projects, including the southward extension of the Northern Line to Morden in 1925-6 and a new headquarters in 1928-30. A revival of 18th century monumental styles then dominated British architecture.

 In contrast, Holden's design for the 55 Broadway headquarters, over St. James's Park tube station, was original and modern: not just a building but a complete design. He commissioned sculptures for the exterior of the building from contemporary artists - Jacob Epstein, Eric Gill, Eric Aumonier, Henry Moore, A.H Gerrard, Samuel Rabinovich and Allan G Wyon. The most controversial - considered indecent at the time - were the two groups by Epstein, Day and Night. His attention to this kind of detail typefied Holden's commitment to total design.
