Rabih Hage-designed Boltons mansion hits the market at £30m

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

A three-bed penthouse in Fitzrovia with one of London's biggest roof terraces - it's bigger than the average family home - has come up for sale, asking £6.995m.

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
