Summary - Flat 22, 51 South Street W1K 2XL
3 bed 3 bath Apartment
Turnkey luxury with terrace and private garage in central Mayfair.
Extremely large duplex penthouse — approx. 2,380 sq ft
A rare duplex penthouse set across the fifth and sixth floors of a distinguished Victorian mansion block in Mayfair. Recently renovated throughout, this three-bedroom home offers exceptionally generous proportions (approx. 2,380 sq ft), high ceilings, and a private terrace with treetop outlooks — a spacious urban retreat in one of central London’s most prestigious pockets.
Interiors are finished to a refined contemporary standard: an open-plan reception and dining area with large windows, a sleek marble kitchen with integrated appliances and wine cooler, and three ensuite bedrooms with built-in storage. The principal suite provides substantial fitted storage and a marble-finished bathroom. Practical benefits include a private garage, 24-hour concierge, community heating scheme, and excellent connectivity for mobile and broadband.
Buyers should note clear running costs: an extremely high annual service charge of £22,000 and a very expensive council tax band apply. The property is leasehold (long lease, circa 910 years remaining). The surrounding area records high crime levels for central London — buyers seeking maximum privacy and security should consider additional measures despite the concierge service.
This home will suit purchasers seeking a turnkey, luxurious pied-à-terre or primary residence in Mayfair with room for entertaining and family living. There is some scope to personalise finishes further if desired, but the refurbishment presents a largely move-in condition for those prioritising location, space and classic period character combined with modern amenities.
