The building located on Smith Square and Dean Bradley Street, London, England was owned by the T&G and officially opened in May 1928. The T&G started to occupy it from 1926, moving from their first headquarters in Matthew Parker Street.[2][3] The TUC moved out to Congress House between 1956 and 1958. The Labour Party moved out in 1980, transferring its headquarters to what later became known as John Smith House. The T&G remained until the 1990s, when they moved to a modern building on Theobalds Road, Holborn, which is now also known as Transport House.
