55 Broadway, London

The building in back was opened in 1929 as the headquarters of the Underground Electric Railways Company of London, later part of the London Underground. The architect was Charles Holden, and the building features sculptures by several important sculptors. One of the sculptures, by Jacob Epstein, outraged many when the building opened, until Epstein agreed to chop off its penis.

Transport for London announced plans several years ago to move out of the building by 2015, but according to TripAdvisor it ran an open house there three weeks ago, so still seems to be using the building.
