An incredible Grade II listed townhouse in Mayfair, London, is up for sale at an astounding £54.5million, making it the most expensive home in the market since the national lockdown.

The prestigious mansion has been around for a while too. Sitting on Upper Grosvenor Street, the old townhouse was built back in 1732 and was refurbished by Chelsea-born architect Ralph Knott in 1908.

The Main Sitting Room Occupies Almost An entire floor

The property spanning six storeys and occupying more than 14,500 sq ft is owned by a Jersey-registered company, Boss Holdings Ltd. Its current owners gloriously modernized it while still paying homage to its history.

The townhouse was previously rented out for £27,500 a week and is now being sold for 32 times more than the £1.7million it cost to buy back in 2008.

So whats the deal with its immense asking price? Quite a bit, to be fair.

The palatial pad features 12-bedroom, nine bathrooms located at the much-envied Portland Stone residence in central London.

The Pad Is Configured For Both Formal Entertainment and Comfortable Family Living

The property includes the main mansion building and an additional mews house overlooking Culross Street, all of which date back to 1869.

Sauna For Relaxation After A Long Day


Below the property is a large connected basement accessed via a lift. Home to a massive 73ft long swimming pool as well as a wellness center, a jacuzzi, a fitness studio, a sauna, and a private cinema for relaxation. Also on that level are two bedrooms located in the mews.

Besides, the ground floor also includes a study, a dining room – which can fit 20 guests – a gym, and garage space, then on the second floor is a large L-shaped reception room, – which leads out to a large terrace – another smaller kitchen, a bedroom, and a bathroom.

There are five main bedroom suites, including the master bedroom, all of which take the entire second floor and have their own terrace.


On the third floor are two more bedrooms, each fitted with its own dressing room and a bathroom. The fourth floor repeats the same. This brings the total number of bedrooms in the palatial residence to 12. Maybe it could be a family home? Or a great holiday home for a group of 12 friends with deep pockets seeking the best in luxury.
