Congress House is the headquarters of the Trades Union Congress (TUC), an organization which represents most of the trade unions in the UK. Designed in 1948 by David du Roi Aberdeen, it is one of the significant bauhaus inspired buildings in London.

Aberdeen used geometric shapes on the exterior and interior, a color theme of aquamarine and white, free flowing spaces from basement to street level and significant bronze sculptures inside the massive central space and at the entry.
