Mr Hughes designed the residence as part of a collaboration with Swiss company exklusivHAUS – creators of unique custom homes – for a client requesting something out of the ordinary.

The completion of the property took five-and-a-half years at a cost of $12.2 billion (£7.5 billion), making it the world’s most expensive home, usurping a $2 billion (£1.2 billion) Mumbai property owned by Indian businessman Mukesh Ambani.

The house, which resides at a secret location in Switzerland near the Italian border, also features platinum fixtures and fittings and flooring made from meteoric stone with shavings of original 65-million-year-old T-Rex Dinosaur bones embedded in each tile.

Spread across 2,442 square metres, the property boasts 8 rooms, a vast terrace, a basement with a special stone wine cellar and a garage large enough for 4 cars.

Amongst the other gold luxury items created by Stuart Hughes are a Rolls Royce Phantom and an Apple iPhone 4.
