Macdonald House was a seven-storey Neo-Georgian style building on Grosvenor Square in Mayfair, London. It was part of the High Commission of Canada from 1961 to 2014.[1] Macdonald House was used for the High Commission's cultural and consular functions, trade and administrative sections, immigration section, and as the High Commissioner's official residence. From 1938 to 1960, the building was the Embassy of the United States.[2]
The Government of Canada sold Macdonald House to a property developer in 2013 and vacated the building in 2014.[1] Subsequently, Macdonald House was converted into high-end residential building named №1 Grosvenor Square.[3]
