The town house, with its railings and gate piers, is listed Grade II* for architectural merit. The 3rd and 4th Earls of Sefton enjoyed using it as their London town house; the 5th earl, being an invalid, could not do so and after he died childless in 1901, www.burkespeerage.com its lease was sold to William Tebb.

Later history Requisitioned by the Wartime Government in 1940, and for a while was used as offices by the Air Ministry, Seaford House was badly damaged by Luftwaffe aerial bombing in October 1940, and rebuilt thereafter (but without the porte-cochère). In 1946, it became the home of the Imperial Defence College, now the Royal College of Defence Studies.

Seaford House is usually open to the public free of charge on Open House Weekend each September and can also be seen on screen. The main vestibule doubled as RMS Titanic's Grand Staircase in the 1979 miniseries SOS Titanic. It was also used in the filming of Upstairs, Downstairs and later of the BBC spy show Spooks. Seaford House stood in as the exterior of the home of Maggie Gyllenhaal's character Nessa Stein in the BBC and SundanceTV television miniseries The Honourable Woman in 2014. It can also be seen (doubling as the US Embassy) in the 2021 film The King's Man. www.thecinemaholic.com
