A house on Eaton Square, last purchased in 2009 for £33m, has come on the market again with a price tag of £70m. Before this, it was sold in 2005 for just £9.5m.
Its interior was designed by Bianca Ladow, executive director of EarlCrown, which specialises in interior design for high-end luxury properties.
Former residents of Eaton Square include Nigella Lawson and Charles Saatchi. Chelsea manager Roman Abramovich has a property nearby.
The square is also the fictional home of 007 spy James Bond.
Estate agents Knight Frank describes the property as a "substantial freehold townhouse situated in the most sought-after Belgravia address".
"The house benefits from superb views over Eaton Square, passenger lift, mews with double garage and a swimming pool," it adds.
The property is 10,710 sq ft, making it worth £6,500 per square foot - more than the apartments sold at the Candy brother's One Hyde Park.
It has six floors. The first floor features a drawing room with a "winter garden with retractable glass ceiling".
On the lower floor, there is a swimming pool tiled with gold mosaic and a gold ceiling, a gym, a spa and a Jacuzzi.
Its seller is Hong Kong businessman Joseph Lau, whose other assets include a Boeing 787 Dreamliner jet and one of the world's finest red wine collections.
Before Lau bought it, was owned by Del Monte Foods tycoon Vivian Imerman and his former film producer wife, Lisa Tchenguiz.
Their ended up being one of the most expensive in Britain, with Tchenguiz seeking £100 million for Imerman's fortune.
Before they split, they hosted numerous parties at the Eaton Square townhouse.
