Property of the week: This £30m Belgravia mega-mansion is so big it could be an art gallery and a boutique hotel

Have a collection of artistic masterpieces but no space to put them? If you have a spare £30m in the bank, then you could be in with a chance of purchasing this mega-mansion in Belgravia that’s not just an enormous home but has enough space to spare to double up as a boutique hotel.

Originally built as two separate dwellings in 1821 by the Grosvenor family estate, it became a single property in 1982 when the owners knocked them through.

Architects H Larizadeh and Weber-Brown then put connecting doors on every floor to create flat-level living space across six floors, making it the perfect property to showcase an international art collection. It now comprises 8,372sqft of living space, fitting in 11 bedrooms, eight bathrooms and five living rooms. It measures 10 windows across and it’s 23 metres long.

“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,” says Becky Fatemi, managing director of Rokstone, the estate agency handling the high value sale.

“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 garden terrace

International hotel designer Jinnie Kim has taken care of the interiors, working with the property’s unique architectural history. Ornate coving and a grand working fireplace on the first floor add period grandeur, complemented by views of St Paul’s church in Knightsbridge, which was designed by the Thomas Cundy II, the same architect attributed with creating the crescent itself.

Modern additions include a master bedroom suite that takes over the entire second floor, with a spare ‘snoring room’ for noisy bedfellows.

It’s also set up for entertaining with two private entrances –Doric porches, of course – for staff and guests and a professional kitchen fully fitted with industrial units connected to the family kitchen by the dumb waiter.
