About this property

Smart Move Mayfair is proud to announce a stunning off market freehold house on one of just twelve garden facing freehold houses on Eaton Square – the jewel in the crown of the Grosvenor Estate and what is commonly regarded as the best address in London.

Refurbished to the highest possible standard this Grade II* listed house has notable features rarely found in townhouses of this era. Of particular interest is the full width reception hall providing a superb sense of arrival on entry, a passenger lift and food lift to every floor on the level, and the closet wing extension providing the maximum possible floor area on every upper floor.

The agent hasn't said which band this home is in; you can look it up on GOV.UK. In Westminster, 2026/27 bills run from £700 a year in band A to £2,099 in band H.

Figures from MHCLG (Open Government Licence v3): the average bill for each band across Westminster, including the typical parish precept, so a parish's own bill can differ a little. Discounts lower the bill, such as 25% off for an adult living alone.
