The house was subsequently acquired by Alfred Beit, and his brother Sir Otto Beit inherited it in 1906.[3] His son Sir Alfred Beit, 2nd Baronet, grew up there and on his father's death in 1930 inherited the house, together with his large art collection. He relocated to Kensington Palace Gardens, and sold the house in 1936.[6]
The building was acquired by Argentina in 1936, and has since been used as that country's Ambassador's official London residence.[7] It has been opened to the public on one weekend a year since 2006, as part of Open House London, which notes the "sumptuous interiors still intact".[2]
During the Second World War, the house became a meeting place and haven for Argentines who volunteered in the British forces, mostly as pilots.[3]
