The smallest floor in the building has the only private terrace. The eighth floor at 4 Golden Square is the penthouse of a refurbished mid-century block, and the terrace looks over the square and catches the sunset. Inside, a kitchenette, air conditioning, ash floors and pendant lights on a dimmer. A four-person lift brings you up, and the shared fourth-floor terrace is there when the whole team wants lunch outside. Piccadilly Circus is five minutes on foot, Bancone less. For a founder, a fund or a film company that wants the top of Soho without the floorplate.
