[2] The Embassy of Sweden in the United Kingdom is organized into several key departments:[2] In 1907, the Swedish legation in London moved into rented premises at 73 Portland Place.

In 1921, the townhouse at 27 Portland Place was purchased and a 999-year lease with the English landowner Baron Howard de Walden was agreed.

[3] The purchase price was 1,200,000 Swedish kronor, with a 999-year lease contract for a total redemption sum of 27,000 pounds.

[5] After the Second World War, the embassy found itself increasingly in need of space and the neighbouring property 29 Portland Place was therefore rented.

[6][8] Since 1983, the chancery building is located at 11 Montagu Square in Marylebone, just down the road from the embassy of Switzerland.
