A rare “Upstairs, Downstairs” style mansion on one of London’s most exclusive squares has come onto the market for the first time this century with a £35 million price tag.
It has seven reception rooms, a study, family den, teenage retreat at the top of the house and five bedrooms, as well as staff quarters.
The lower-ground floor is a wellness retreat with swimming pool and gym.
Original period features include ornate moulding, huge stone fireplaces and grand staircases.
The Grade II-listed property was designed in 1880 by architect FG Knight for Oscar Leslie Stephen, a director of the Great Northern Railway, and completed in 1884.
Becky Fatemi, of Rokstone Properties, which is handling the sale alongside Savills, said: “Complete townhouses are a collector’s item and comparable to very rare fine art... I expect a family, art enthusiast or a collector of trophy homes to buy this home.”
