Macdonald House, London

After a new Modernist style building at 24 Grosvenor Square (designed by Eero Saarinen) was completed in 1960, the American embassy moved to that site.

On December 20, 2010, the Department of Foreign Affairs and International Trade announced that Canada House, the High Commission's diplomatic, public and educational space in London, would close to undergo necessary renovations.

On November 28, 2013, the Canadian government announced that Macdonald House had been sold to an India-based developer (Lodha Group) for $530 million.

[8] The developer is recreating the Neo-Georgian architecture of Macdonald House in a new, high-end residential building called No.1 Grosvenor Square.
