600 flats were snapped up, costing up to £6m each, at what was thought to be the fastest selling property development on record.

More than £600million worth of property inside London’s redeveloped Battersea Power Station has been sold in a four-day stampede.

Prices ranged from £343,000 for a studio to £6million for a penthouse as 600 flats were snapped up at what was thought to be the fastest selling property development on record.

Rob Tincknell, chief executive of Battersea Power Station Development Company, said: “It’s been like the start of the Harrods sale.

“It really has been phenomenal. We had people queuing from 6.30am on Thursday and the London allocation sold out in days.”

By the time the sales centre at the riverside site closed on Saturday afternoon 600 buyers, from City bankers to a former power station worker, had written out cheques.

Buyers have to pay a £2,500 booking fee followed by 10% of the purchase price on exchange, which has to be within four weeks.

The keenest interest was for the larger townhouses and penthouses overlooking the Thames, which have multi-million-pound price tags.
