Winfield House

Winfield House is a Grade II listed ambassador's residence in Regent's Park, Westminster. The Georgian Revival mansion built from red brick shows Portland limestone on facade details and slate roofing over the main buildings.

Architect Leonard Rome Guthrie designed the building in 1936 to replace Hertford Villa after it burned down. Construction finished shortly before World War II began, which delayed the use of the house initially.

The ambassador's residence takes its name from Winfield Woolworth, grandfather of original owner Barbara Hutton. The expansive estate continues to serve as a venue for official receptions and social events hosted by American diplomacy in London.

The grounds remain closed to the public and are accessible only during rare official occasions. The private gardens spread across roughly 12 acres with formal beds, tennis courts, and walking routes.

Barbara Hutton transferred the estate to the United States government in 1955 for one dollar symbolically. The garden ranks today among the largest private gardens in central London by size, surpassed only by the grounds of Buckingham Palace.
