The $127 Million Restoration of Britain’s Most Expensive Home

The renovations alone are estimated to have cost $127 million.

Mayfair is one of London’s priciest neighbourhoods; for decades, it’s been an ultra-exclusive enclave of wealthy Arab oil tycoons and celebrity-laden nightclubs. So it comes as no big shock that what is quite likely Britain’s most expensive home is located in the posh neighbourhood. What is surprising, though, is that the owner of the $450 million-plus property is John Caudwell, an Englishman with working-class roots who made his fortune through the mobile phone company Phones 4U, which he sold for approx $2.9 billion in 2006.

Known as Mayfair house, Caudwell’s roughly 3995 sq. m. mega-manse was purchased in 2012 for about $150 million. After a few years of throwing lavish parties, Caudwell recently embarked on an epic-scale renovation that reportedly ran him an astonishing $127 million.

The construction project reportedly employed 300 workers and is the subject of the new Channel 4  documentary, “Britain’s Most Expensive Home: Building For a Billionaire.” And it’s a far cry from the council estate (the U.K. version of a housing project) in which Caudwell grew up. The property was purchased from a Channel Islands trust that linked to Jefri Bolkiah, the unfathomably rich and famously profligate younger brother of the Sultan of Brunei. From the exterior, it looks similar to the many Middle Eastern banks and embassies that surround it; inside, however, it’s a theme park of opulence. Here’s a brief summary:

  • The house contains 15 bedrooms on eight floors, three of which are subterranean
  • 20,000 sheets of gold leaf were used in the interior
  • 650 electrical sockets
  • 78 miles of newly installed cables
  • An underground car stacker system can hold up to eight vehicles
  • A total of 9715 cubic-metres of earth was excavated to accommodate geothermal heating and cooling amidst other subterranean delights
  • There is a river in the dining room which is 16.5 inches deep populated with African cichlid fish
  • The ballroom can host 120 people

A dedicated philanthropist, Caudwell doesn’t intend to use the property as his main residence. Instead, he hopes to host charity events for Caudwell Children, a 20-year-old charity he founded dedicated to helping children with disabilities and their families.

“I just thought how magnificent it would be for gala evenings,” Caudwell told The Times of London about the ballroom. “It was so unique that it really did excite me, mainly from a charitable perspective, because I don’t need a house anything like that size.”

The 67-year-old billionaire is the 97th richest person in the U.K., according to The Sunday Times Rich List. He has been married once and has five children from three different relationships. He’s currently dating 36-year-old Lithuanian cycling champion and former Olympian Modesta Vzesniauskaite.

Unlike its muted exterior, which mostly blends into its surroundings, nothing about the home’s interior is understated. Given Caudwell’s taste in sparkling, Elton John-like jackets (which are displayed on mannequins in the home), it’s hardly surprising that there’s a more than just a hint of Liberace or Louis XIV about the place. The extensive renovations of the mansion include a “volcano” wall, a swimming pool and staircases of solid white marble that connect to each of the eight floors. There’s also an Art Deco-inspired, lattice-fronted elevator, a cocktail lounge with low-lit velvet booths and a stage for live music plus an adjoining billiards room with a rose-covered ceiling.

“It really has been a labour of love,” Cauldwell said. “I was involved in absolutely every aspect of it.”

But how does the proud philanthropist justify spending such an ostentatious amount of money on a home? “The house itself is a profitable venture,” Cauldwell said. “Far from taking away my ability to give to charity, it increases it because it has increased my wealth significantly. As 70% of that is going to charity … it swells my ability to give during and after my lifetime.”
