EnglandsBuildings's video: Treasury Foreign Office 21 09 14

The Treasury Main Building at 1 Horse Guards Road, often referred to as the Government Offices, Great George Street (GOGGS), was designed by John Brydon following a competition. Construction took place in two phases. The West end was completed in 1908 and the East end was completed in 1917. It was originally built as offices for Board of Education, the Local Government Board, and the Ministry of Works Office; HM Treasury did not move into the building until 1940. A major refurbishment of the building was completed under a PFI contract by Bovis Lend Lease in 2004. The Foreign and Commonwealth Office occupies a building which originally provided premises for four separate government departments: the Foreign Office, the India Office, the Colonial Office, and the Home Office. Construction on the building began in 1861 and finished in 1868, and it was designed by the architect George Gilbert Scott. Its architecture is in the Italianate style; Scott had initially envisaged a Gothic design, but Lord Palmerston, then Prime Minister, insisted on a classical style. English sculptors Henry Hugh Armstead and John Birnie Philip produced a number of allegorical figures ('Art', 'Law', 'Commerce', etc.) for the exterior. In 1925, the Foreign Office played host to the signing of the Locarno Treaties, aimed at reducing tension in Europe. The ceremony took place in a suite of rooms that had been designed for banqueting, which subsequently became known as the Locarno Suite. During the Second World War, the Locarno Suite's fine furnishings were removed or covered up, and it became home to a foreign office code-breaking department. Due to increasing numbers of staff, the offices became increasingly cramped and much of the fine Victorian interior was covered over—especially after World War II. In the 1960s, demolition was proposed, as part of major redevelopment plan for the area drawn up by architect Sir Leslie Martin. A subsequent public outcry prevented these proposals from ever being implemented. Instead, the Foreign Office became a Grade 1 listed building in 1970. In 1978, the Home office moved to a new building, easing overcrowding. With a new sense of the building's historical value, it underwent a 17-year, £100 million restoration process, completed in 1997. The Locarno Suite, used as offices and storage since the Second World War, was fully restored for use in international conferences. The building is now open to the public each year over Open House Weekend. Filmed during Open House 2014
