Carlton House Terrace home on the market for £250m

A house on London’s Carlton House Terrace is on the market for £250m.

Touted as “the biggest private home in central London”, the Grade I listed Regency property is 30 times bigger than an average London home and is 700 times more than the £370,000 average property value in the capital.

The house belongs to a Middle East Royal who is “discreetly trying to find a buyer”. The owner, who holds a 78-year lease from freeholders the Crown Estate, is believed to be in talks to extend the lease.

The Standard reports that the brochure reveals only black and white interior pictures from the 1890s because “for security reasons the current owner does not want many of the features photographed”.

The owner of this property would be a neighbour to Sri and Gopi Hinduja who are worth £10.6bn according to the Sunday Times Rich List.

Features of the six-storey house haven’t been revealed but the owner is said to have “invested millions” in restoring the interiors of the house.

The source told the Standard: “The building is very much as it was in its heyday. It would be for a new owner to put in the modern toys such as a swimming pool.”

The house is designed by Buckingham Palace architect John Nash and was used as the Enquiry Department for Wounded and Missing in the First World War, the British Red Cross and Order of St John.

Other expensive private homes in the capital include One Cornwall Terrace, that property tycoon Marcus Cooper bought for £80m in March. Last week, the Reuben brothers won permission to turn Picadilly’s In and Out Club into a £200m home with 11-bedrooms, an underground swimming pool, an 85 ft ballroom and a 35,000-bottle wine cellar.
