Sarum Chase is a Grade II listed neo-Tudor mansion, at 23 West Heath Road, Hampstead, London, described by Nicholas Pevsner as "pure Hollywood Tudor". It was built in 1932 as the home and studio of portrait artist Frank O. Salisbury. The word Sarum is the old name for the town of Salisbury. The architect was Vyvyan Salisbury, his nephew. The author's wife cut the first sod on the site, on 4 September 1932.
