Singapore's largest and most expensive penthouse is changing hands for $47 million.

But that astronomical price tag represents a loss of around $7 million, or 13%, for the seller James Dyson, the vacuum cleaner billionaire.

Dyson bought it in July 2019 for a a reported $54 million.

The penthouse occupies the top three floors of Singapore's tallest building, the 64-floor Guoco Tower in Tanjong Pagar.

The 21,000 square foot flat has a swimming pool, jacuzzi, and a 600-bottle wine cellar. It also boasts views over the city's harbor and financial district.

Dyson, who invented the Dyson vacuum cleaner and is Britain's richest man, has accepted an offer from billionaire Leo Koguan, the chairman of IT provider SHI International, Singapore's Business Times reported on Monday.

Kougan was born in Singapore but is now a US citizen.

The property is the largest "non-landed residence" in Singapore, according to accompanying marketing materials.

It is also Singapore's most expensive penthouse, once valued at 100 million Singapore dollars ($74 million), CNBC reported.

Dyson bought the flat after he announced his company would be moving its headquarters to the city-state.

He was a vocal supporter of Brexit, and its opponents accused him of hypocrisy when he first announced the company move in January 2019. However, the firm insisted that its move to Singapore was unrelated to Brexit or tax reasons.

The penthouse sale won't affect Dyson's plans as a business, a spokesperson told CNBC.

The Dyson family also owns a 15,000 square foot bungalow in the city-state overlooking the botanical gardens. The property, which has an infinity pool and an indoor waterfall, is thought to be worth around 50 million Singapore dollars ($37 million), the BBC reported.
