St Andrew's House

St Andrew's House (SAH) (Scottish Gaelic: Taigh Naoimh Anndra), on the southern flank of Calton Hill in central Edinburgh, is the headquarters building of the Scottish Government. The building houses offices for the First Minister and Deputy First Minister, as well as the Permanent Secretary to the Scottish Government.

When completed in 1939, the building was the largest metal-framed building in Europe, and was the first time government departments serving Scotland were brought under the same space in Edinburgh.

Built on the site of the old Calton Jail, the graves of ten murderers who were housed within Calton Jail remain buried beneath the car park for St Andrew's House. The turreted Governor's House is the only remaining part of the Calton Jail to remain in existence following the construction of St Andrew's House. The building accommodates 1,600 civil servants from the Scottish Government over six floors within the building.

The building was designed by Thomas S. Tait of Burnet, Tait and Lorne, architects, who won the architectural competition to gain the commission. Construction began in November 1935 and was completed in 1939; the building initially housed the Scottish Office, including the offices of the Secretary of State for Scotland. The heraldic sculpture on the front is by John Marshall.

The requirement for the building arose as a result of a post First World War policy of limited transfer of devolved administrative (but not legislative) power to Scotland from London. The building opened to staff on Monday 4 September 1939 (the day after War was declared). An official royal opening ceremony timed to take place on 12 October 1939 was "cancelled due to War" (Britain's first air raid of the war took place only four days later over the Forth Bridge). Instead, it was officially opened by King George VI and Queen Elizabeth on 26 February 1940.

St Andrew's House was officially completed in 1939 and opened on 4 September 1939. The building was opened less than 24 hours after World War II had officially been declared, and as a consequence, the official opening ceremony due to be attended by the King and Queen planned for the following week was cancelled. Shortly after opening, the building quickly became covered in soot and grime which quickly blackened the facade of the building from nearby passing trams and trains. As a result, plans began to be considered by 1940 for the electrification of trams and railways, however, these plans were ultimately shelved and the electrification of both would not be achieved until fifty years later.

Opening during a war period, the early years of the building were turbulent. The Civil Service had long been preparing and considering attacks on Scotland, with Princes Street Gardens being dismantled and dug up to develop air raid shelters in preparation for air raid attacks by Nazi Germany. Considerable parts of Scotland were also being excavated to develop airfields and other defences, with emergency hospitals created in order to cater for anticipated casualties.

St Andrew's House, as a government building, was a considerable target for Nazi Germany. It was the location of the first meetings of the new Council of State and of Scottish MPs convened by Secretary of State for Scotland, Tom Johnston. In preparation for attacks by Nazi Germany, it was decided that large numbers of government files from previous decades were to be destroyed by staff in order to prevent a major conflagration in the event of an incendiary bomb attack. Dover House, the Scottish Office building which is located in London was abandoned for the duration of the war as a consequence of bomb damage to adjoining properties following air raid attacks in London.
