£10m Victorian period piece comes to the market in Kensington

When properties come up on London's Carlton House Terrace, it's generally seen as a pretty big deal.

A single, 15,000 square foot stonker would pack 12 bedroom suites, six-metre ceilings and could be worth, according to some estimates, up to £150m

It may be one of New York City's most spectacular residential properties, but it seems as though this five-storey penthouse has yet to find a buyer after a full eight years on the market.
