Estate agents believe the latest potential ‘trophy home’ will have no shortage of interest from wealthy foreigners who have been buying up parts of Mayfair.

The Grosvenor Estate now wants to return it to a family home and integrate the mews properties at the rear, stretching the property around 190-feet.

Plans submitted by the Estate suggest the proposed home, which could be around 18,000sq/ft, will boast six main bedrooms, a stunning drawing room, staff quarters and garages for six cars.

Leisure facilities – which include a gym, underground swimming pool, jacuzzi and a large cinema – will be at the rear.

The second floor will be arranged as an apartment for the mansion’s future owner, consisting of two enormous bedrooms with en suite bathrooms and a large sitting room.

In the lower ground floor is a kitchen, pantry, a room for security, laundry and butler’s quarters.

The dining room alone is more than 800sq/ft in size – the same as the average newbuild home in England.

Previous proposals for work on 8 Grosvenor Square have been approved, but fresh plans submitted to Westminster Council include work on a new sub-basement, basement and ground floors.

‘Grand townhouses in and around Grosvenor Square typically sell for around £3,000 per sq/ft, but by the time work is carried out they could be achieving £4,000 per sq/ft.

‘There is always demand for house like this in Mayfair because they are few and far between. They tend to be popular with wealthy Middle Eastern, Indian and African buyers.

Earlier this week it emerged the Qatari ruling family had paid £40million for a home on Mount Street, adjacent to London’s Hyde Park.
