Billionaire vacuum inventor James Dyson sold his three-storey Singapore penthouse at Wallich Residence for S$62 million ($46m) – just a year after buying the home for a record S$73.8m. The offer on the luxury residence, which Mr Dyson moved into with this wife Deidre last year, has been accepted, according to the <em><a href="https://www.businesstimes.com.sg/real-estate/dysons-sell-wallich-residence-triplex-penthouse-for-s62m">Business Times</a>, </em>making it a drop of more than 16 per cent from the couple's purchase price. Mr Dyson quit the UK and relocated the company's headquarters from Malmesbury in Wiltshire<strong> </strong>to the Asian nation in January last year to "future proof" the business. "An offer has been accepted on the Wallich penthouse," a spokesman for Dyson told Reuters. He declined to comment further on the family's personal property or affairs but said Mr Dyson would continue to maintain a home in the wealthy Asian city-state. Perched atop Singapore’s tallest building, the 64-floor Guoco Tower in Tanjong Pagar, the five-bedroom penthouse is equipped with its own infinity pool and private lift lobby from the basement car park. The buyer is Indonesian-born tycoon Leo Koguan, a US citizen and Texas resident and co-founder and chairman of infotech provider SHI International, which counts Boeing and AT&T among its 20,000 customers, the <em>Business Times</em> said. The apartment's luxury features also include a Jacuzzi and a private garden with city views. Before Mr Dyson bought the apartment, which overlooks the central business district, Marina Bay and Sentosa Island, it was listed for S$108m, making it the city-state’s most expensive penthouse. The eventual purchase price topped the nearly S$60m paid by Facebook co-founder Eduardo Saverin for a penthouse in 2017. The property has been held in the name of Mr Dyson’s wife. The couple also bought a bungalow near the Singapore Botanic Gardens last year for S$50m, which they still own. The inventor of the bagless vacuum cleaner moved his company’s head office to Singapore from Britain to be closer to its fastest-growing markets. In January last year, Dyson chief executive Jim Rowan said the move was not to do with Brexit or tax but added: "It's to make us future-proof for where we see the biggest opportunities."
