Montpelier Square sits between Harrods and Hyde Park, a cluster of 47 Georgian mansions that has become a barometer for high‑end London real estate. Seven homes are now on the market, averaging more than 15 months on sale, with one property still unsold after two years. One recent sale fell over 30% below a decade‑old price; inflation has cut that figure by more than half.

Number 42 Montpelier Square sold in January for £10mn, at £1,932 per sq ft, after 343 days on the market. In 2014 the same lot would have fetched close to £3,000 per sq ft. The current listing for a five‑bedroom home is priced at £4.75mn (~£1,600 per sq ft), a reflection of the market’s new baseline.

London’s premium market has contracted 12% from its 2016 peak of £1,247 per sq ft. The Holme in Regent’s Park recently sold for £190mn, a third higher than its 2022 price. Key drivers include stamp duty increases, Brexit, the end of the non‑dom regime, and rising construction costs that shift buyers toward move‑in ready properties.

Investors face a window of discounts on older stock, while buyers with renovation budgets may discover value. A £75mn streetscape upgrade could lift demand, but the trend toward pied‑à‑terre units signals a longer‑term shift in luxury buyer preferences.
