Comprising two adjacent houses in London’s upscale Belgravia, this 8,372sq ft mega-mansion on desirable Wilton Crescent is for sale with leading agents Rokstone for a cool £30 million.

Boasting an additional 1,414 sq ft of external space and balconies, this unrivalled mansion is Grade II listed, offering 11 bedrooms, five reception rooms and an unrivalled position in the heart of Belgravia overlooking award-winning gardens.

Originally built in 1821 as two separate houses, this stunning central London mega-mansion was created by architects H Larizadeh and Weber-Brown in 1982 when heritage and planning laws were less stringent. Originally built in 1821 by the Grosvenor family estate, the mega-mansion is located where the east side of Wilton Crescent meets Wilton Place.

The palatial house is perfect for entertaining since it allows for guests and hosts through one front door and staff through the other, as it benefits from two private entrances with Doric porches.

To create the combined mega-mansion, the architects inserted connecting doors on all floors, creating lateral living space on six levels. The elegant façade spans an unparalleled 10 windows across, over 23 metres long, with an enviable south-west facing front in a highly prestigious location.

Wilton Crescent’s expansive lateral living means it is ideal for showcasing an international art collection. Its vast size also means a new owner could use one floor to create their own health spa or leisure complex.

Neighbouring houses in Wilton Crescent include the High Commission of Singapore and the Embassy of Luxembourg.

Becky Fatemi, Managing Director of Rokstone, commented, “Wilton Crescent is one of the finest homes to come to the Belgravia market in many years. It’s quite simply ‘the Picasso Mansion’ – ideal for showcasing artwork. Not only does it offer vast living space for a family, but it’s very rare to find a home in Belgravia with such expansive lateral living space above ground, created from the joining of two properties.

“There are less than half a dozen mega-mansions in Belgravia and Knightsbridge, and Wilton Crescent offers a mega-mansion as one palatial trophy home.”

The ground floor boasts an impressive entrance hall with a lift that opens directly onto all floors of the property rather than onto a separate landing like most homes on the Crescent.

There is a grand formal dining room with an adjoining servery room, which has bespoke joinery throughout. A large study with fitted wooden shelving and a working fireplace, one of the many preserved period features throughout, overlooks the tranquil Wilton Crescent gardens.

The ground floor also offers a large guest bedroom with ensuite bathroom and a guest cloakroom. Wilton Crescent has a secure integrated double garage, as well as the option for private parking spaces along Wilton Place, both a desirable amenity for central Belgravia.

The first floor offers a vast reception/dining room, with double doors opening onto a private balcony looking towards Wilton Crescent gardens and another balcony overlooking Wilton Place.

Featuring a grand working fireplace and ornate coving, the room is perfect for entertaining guests or relaxing as a family; large enough for a grand piano, luxury furnishing and a study area.

The first floor also offers a sitting room, with bespoke cabinetry, and a family kitchen. The former, the sitting room, opens onto a large outdoor dining space with seating areas on a private terrace and views over St Paul’s Knightsbridge church.

The colourful family kitchen adjoining the sitting room offers residents the space to enjoy eating together while also benefitting from a dumb waiter on the lower ground floor, where a professional industrial kitchen can be used for preparing meals.

Wilton Crescent’s entire second floor is an expansive master suite; a testament to the opulent and ample space available at this prime London address. It comprises two bedrooms: one principal master bedroom and a second bedroom as a ‘snoring room’ allowing potential buyers to enjoy their own space. Both bedrooms benefit from ensuite bathroom facilities and a dressing area.

The property’s third floor boasts a further three large guest bedrooms, one with an ensuite, with a family bathroom and a large TV room which opens onto a spacious balcony. This balcony also offers enviable views of St Paul’s Knightsbridge church. The property’s fourth floor offers a further two guest bedrooms, with a guest cloakroom and separate shower.

Below ground floor level, the property continues with thoughtfully designed staff quarters. On the lower ground floor, there is a self-contained staff annexe with two bedrooms, a reception room, utility room, bathroom and a separate entrance allowing staff privacy and easy access to Wilton Place.

Also on the lower ground floor, Wilton Crescent has a further guest bedroom with an ensuite, taking the total number of bedrooms to 11 and the total number of bathrooms to eight. A professional kitchen, fully fitted with industrial units and connected to the family kitchen by the dumbwaiter, opens onto a patio space.

The lower ground floor offers secure storage, with a professional safe vault and a further three vaults accessed via a private patio.

Internationally-acclaimed hotel designer Jinnie Kim has created an opulent design throughout, with the property’s size offering a fantastic opportunity for personalisation.

Wilton Crescent is ideally located, benefitting from both the tranquil calm of its residential address and is a short walking distance to London’s best luxury shopping, with Harvey Nichols and Harrods in neighbouring Knightsbridge. St Paul’s Church, Knightsbridge, dates to 1843 and was designed by the same architect as Wilton Crescent, Thomas Cundy II.

The green expanse of Hyde Park and Green Park are also a short walk away, perfect for raising a family. Wilton Crescent is very well connected for business or leisure in London, with Knightsbridge underground station just a seven-minute walk from the Piccadilly line, connecting to London St Pancras International in just 13 minutes.
