An £18m mega mansion in Grosvenor Square has become the most expensive apartment per square foot ever released onto the Mayfair market.

Priced at a record £5,130 per square foot, the home is 72 times the price of an average UK home.

The annual service charge for the home is over £20,000, which is almost equivalent to the price of the average UK salary (£26,500).


The four-bedroom apartment boasts panoramic views over Grosvenor Square and comes with gold leaf panelling and marble fireplaces.

The double reception room is 43 ft long with five south facing windows overlooking the garden square. Features include full height marble fireplaces at either end, mirrored feature walls and gold leaf edge wall panelling.

The apartment also includes a 10-12 seater dining room, has a bespoke mirrored bar and cabinets and a custom-designed kitchen with super-luxury Gaggenau and Miele appliances.   


Peter Wetherell, managing director, Wetherell, said: “Grosvenor Square has seen significant capital value uplift and in the last three years has overtaken rivals Eaton and Cadogan Square to become London’s most valuable residential square. For Grosvenor Square, the next decade will be the most significant in its history.

“Whilst there are no developments in the pipeline for Cadogan Square and very little for Eaton Square, the relocations of the US Embassy; the US Navy offices and Canadian Embassies out of Grosvenor Square will potentially provide up to 80 new luxury apartments whose per square foot values will set new price benchmarks for Mayfair.”
