In 1955, the Technical College received a large gift of land. Local Architect, property developer and entrepreneur Tom Scott Sutherland, purchased the Victorian manor and estate of Garthdee House in 1953 on the outskirts of the city. Finding himself and his wife living out of only four rooms in the enormous mansion, he donated it and the estate in 1955 for a new school of architecture. These classes had taken place at Gray's School of Art, but had been expanding in the 1940s and 1950s and much more space was needed. Following completion of a modern extension to the house, the new Scott Sutherland School of Architecture opened in 1957. In 1966, Gray's School of Art also moved to a large new building on this estate, freeing its Schoolhill building for administrative use. By 2013, all activities had transferred to Garthdee, with the addition of land immediately adjacent purchased from Aberdeen City Council in the 1990s.
