Macdonald House, Former diplomatic building in Mayfair, United Kingdom
Macdonald House is a seven-story Neo-Georgian building at 1 Grosvenor Square featuring symmetrical facades, tall windows, and ornamental stonework. The structure displayed the careful architectural proportions typical of that prestigious London square.
The building opened as the United States Embassy in 1938 and became Canada's High Commission from 1960 onward. Its use as a diplomatic residence ended in 2014 when Canada moved its London operations elsewhere.
The building hosted official meetings and receptions where Canadian and British diplomats conducted their business and represented their nations. These functions shaped the rhythm of activity on Grosvenor Square for several decades.
The building is no longer open to the public as it was converted into private residential units. Visitors can view the Neo-Georgian exterior from the street and appreciate its architectural details as part of the square's composition.
When converted to residential use, the original facade was carefully dismantled and reconstructed as part of the new development. This preservation technique demonstrates how historic facades are integrated into contemporary London construction projects.
