A refined three-bedroom duplex penthouse set across the fifth and sixth floors of a Queen Anne mansion block on prestigious South Street. Newly renovated interiors combine contemporary fittings with period proportions, delivering generous living spaces and high-quality finishes across approximately 2,076 sq ft. The principal suite includes a walk-in dressing area and bespoke marble en suite; both additional bedrooms are en suite.
Practical comforts include air conditioning, lift access and a 24-hour concierge, plus excellent mobile signal and fast broadband. The apartment overlooks Mount Street Gardens and sits moments from Berkeley Square and Grosvenor Square, placing Mayfair dining, galleries and specialist shops within easy reach. Local schools range from highly rated state primaries to top independent senior schools.
Buyers should note clear cost and security considerations: the property is leasehold (long lease remaining of 946 years) with an extremely high service charge (£21,632 p.a.) and very expensive council tax. Crime levels in the immediate area are recorded as very high, and the building’s solid brick construction likely lacks modern cavity insulation, which may affect thermal performance despite the community heating scheme.
This is a premium Mayfair pied-a-terre or family residence for buyers seeking turnkey, centrally located accommodation with strong entertaining space. It suits purchasers who prioritise location, refined finishes and concierge service, and who can accommodate above-average running costs and local security considerations.
