Audrey and Jeff Lovelock are desperate to live in one of west London's most exclusive areas - but the only way they can afford it is to go underground. Their plan is to transform a listed Edwardian artists studio - along with 5,000 square feet of derelict basement rooms below - into a bespoke, subterranean home, including a supersize kitchen dining area, a new mezzanine sitting room, four en-suite bedrooms, a gym, large cinema room, steam room and wine cellar. But buying this labyrinthine place requires an almighty leap of imagination. With its 13 different levels and 25 interconnecting rooms it's questionable whether it can ever make a desirable home, especially given 90 per cent of the rooms have no natural light.
