SW7 3QF
Onslow Gardens, South Kensington, London, SW7
Positioned on one of South Kensington’s most distinguished garden squares, this exceptional penthouse apartment crowns an elegant period building on Onslow Gardens, offering refined lateral living, direct lift access and expansive private terraces.
Occupying the upper floors and extending to approximately 1,619 sq ft, the apartment is centred around a striking 33 ft reception and kitchen space, a beautifully proportioned room with impressive ceiling heights and an abundance of natural light.
The fourth floor also hosts two generous bedrooms. The 21 ft principal suite is elegantly arranged with a private en suite bathroom, while the second bedroom benefits from a walk in wardrobe and access to a separate bathroom.
A sculptural spiral staircase leads to the upper level, where two interconnecting roof terraces unfold. Generous in size and wonderfully private, they offer far reaching views across South Kensington’s iconic rooftops, a rare outdoor setting for al-fresco dining, sunset drinks, or quiet retreat above the city.
Onslow Gardens is synonymous with grand architecture and prime positioning. Moments from the boutiques and cafés of the King’s Road, Old Brompton Road and Fulham Road, and within easy reach of Gloucester Road and South Kensington Underground stations (District, Circle and Piccadilly lines), the address perfectly balances connectivity with village-style charm.
