Hot property tycoons the Reuben Brothers recently secured planning permission to turn Piccadilly's famous In and Out Club into London's most expensive home.
At an estimated £200 million, the 48-room property will be transformed into a luxury central London house, with a 35,000-bottle wine cellar and underground swimming pool.
But those keen to invest in the area with a slightly less extravagant budget should take a look at the one-bedroom apartment for sale opposite the site of the former gentlemen's club.
Listed with Hamptons International for £1.75 million, the Half Moon Street flat comes with gorgeous views extending to Green Park. It is an address worth investing in before David and Simon Reuben work their magic.
