West Ham boss David Sullivan is set to make a £50million profit when he sells one of London’s most famous and notorious homes for a predicted £80million.

Media magnate Sullivan plans to put the house on the market in the autumn with the asking price likely to be almost three times the £27million he paid in 2015.

The sumptuous home in Portland Place, Marylebone, central London, is famed for its cultural history, including as the setting for Oscar-winning film The King’s Speech, but also for riotous sex and drugs parties.

Since 2015 Sullivan and has poured millions into refurbishing the Grade II listed home which was built in 1776 by Robert Adam and his family.

Workmen are putting the finishing touched to the restoration which is planned to go on sale shortly.

Upmarket estate agents Knight Frank, who sold the property in 2015, have been commissioned to sell it again, but this time for a fee close to £80 million. 

Knight Frank partner Christian Lock-Necrews said: ‘It will be one of the best handful of houses that you could buy in London over the next year.’

Asked about the rumoured £80million price tag, he said: ‘There isn’t a price confirmed at the moment, It’s going to be perhaps in that region but there is not a definitive price yet. It would not be unreasonable to imagine it in those terms.

‘There’s been a huge amount of work. It’s a 24,000 sq ft house, grade II listed, original Adam brothers design.

‘There’s a swimming pool, totally new mews parking, cinema room, spa, roof terrace, with a sky garden.

‘It was originally planned as a house by the owner. Other people may have subdivided houses like this but that was never the intention here.’

The stunning home is spread across six storeys. Pictured is the sumptuous interior of one of its reception rooms

Not only will the buyers get the 21-bedroom home which comes with a mews house at the back, a wine vault, gym, juice bar and outdoor, rooftop kitchen, but they will also be buying a slice of London history. 

The Georgian property was home to a succession of wealthy aristocrats from 1775 when work was completed until after the Second World War.

Residents included The Wyndham family for more than 50 years, the Earl of Sheffield and James Blyth, a millionaire who had founded the famous gin distillers, W.A. Gilbey & Sons.

In 1954 the Government of Sierra Leone took on the house as their embassy remaining in place until 1998, when its history took a sharp change in direction after it was taken over by Edward ‘Fast Eddie’ Davenport, who had made his name organising debauched parties for public school kids.

But in 2011 the house’s party period came to an abrupt end when Davenport was sentenced to eight years’ jail for his part in a £4.5million fraud

He snapped up the lease on the vast home, which was to become the centre of his party empire, for just £50,000 from the Sierra Leone government while the country was embroiled in a civil war.

The six-storey house was used for film shoots, a fashion show and a masquerade ball, and he once reportedly had his swimming pool filled with Cognac so revellers could row through it.

Kate Moss was filmed walking down its staircase wearing nothing but stiletto heels and underwear for an Agent Provocateur advert and Singer Amy Winehouse used it to shoot the video for her hit song Rehab.

In 2010 it was used as one of the main locations for the Oscar-winning film The King’s Speech starring Colin Firth as George VI battling to overcome his stammer.

The venue was also used to host notorious Killing Kittens sex parties run by Emma Sayle, a one-time friend of Princess of Wales, Kate Middleton.

Reports of one event at the house in 2007 said more than 30 party guests writhed on a giant bed in group sex session, while others queued to take drugs in toilet cubicles.

But in 2011 the house’s party period came to an abrupt end when Davenport was sentenced to eight years’ jail for his part in a £4.5million fraud.

He was exposed as a fraudster who duped victims out of their life savings through bogus start-up loan schemes and had to sell 33 Portland Place to pay back £14million to his victims.

It was finally sold to Sullivan in 2015 who then embarked on the ambitious refurbishment project
