Deactivated at the end of series, the aircraft was refurbished by the developers into a piece of art that matches the style of the property.Every good home also needs a garage, and the property’s 12 car “auto gallery” — which includes a Bugatti Veyron, a Pagani Huayra, a Rolls-Royce Dawn and a range of other rare vintage automobiles — doesn’t disappoint.The home’s realtor, Rayni Williams, said the car collection is valued at over $30 million and was a carefully planned extravagance that enhances the property’s exclusivity.“It is not common for a house to be sold with complete collections such as this. Not only is the home completely furnished with the art and the cars but every single inclusion is exotic and unattainable to the masses,” Williams says.According to Bruce Makowsky, the billionaire owner of BAM Luxury Development group, the home took over four years to construct and furnish, and is designed to cater specifically to the needs of a select few billionaires.“It baffled me that no one was developing luxury real estate at those high levels for the super wealthy,” he says in a statement.“I set up my real estate development company in Beverly Hills, California, to cater to the super affluent that demand the very best in life.”If sold, the $250 million home would be $100 million more expensive than a 32-bedroom luxury mansion in Suzhou, China, which claimed the title of China’s most expensive property in 2016. The most expensive home previously offered for sale in the US was a Beverly Hills property that was listed for $195 million.
