The flat was bought for £80,000 over 20 years ago and has more than trebled in value since. Its £250,000 price tag means that you’re paying a whopping £27,777 for every square metre of floor space. The average property price on Queen’s Gate last year was £2,224,464, while, for the borough of Kensington and Chelsea, the average flat would set you back £1 million. While small, it just about comes in under the average UK property price of £293,000 and is more than half the average property price of London as a whole, which currently sits at £531,000.
