Thatched House Lodge is a royal residence in the London Borough of Richmond upon Thames in London, England.
The main house has six reception rooms and six bedrooms, and it stands in four acres (16,000 m²) of grounds. The gardens include an eighteenth century two-room thatched summer house which gave the main house its name. Since 1963 Thatched House Lodge has been the residence of Princess Alexandra, The Honourable Lady Ogilvy. It was acquired by her late husband, Sir Angus Ogilvy, on a lease from Crown Estate Commissioners following their marriage.
