Summary - Flat 8, 5 Onslow Square SW7 3NJ
3 bed 3 bath Apartment
Rare oversized 3-bed duplex with communal garden in prime South Kensington location..
Extremely large duplex: 1,812 sq ft across two floors
An unusually large three-bedroom duplex in one of South Kensington’s most desirable squares, arranged over the 3rd and 4th floors of an elegant white stucco period conversion. The apartment offers generous principal rooms, three bathrooms and a modern kitchen, making it comfortable for family living or for professionals seeking spacious central London accommodation. Large windows and access to a substantial communal garden provide peaceful green outlooks despite the central location.
Practical attributes include a lift to the upper floors, fast broadband and excellent mobile signal. The building is served by a community gas-heating scheme. The property is constructed circa 1900–1929 with solid brick walls; it displays classic period character alongside contemporary interiors in the living areas and kitchen. Proximity to highly regarded state and independent schools, excellent transport links and a wide choice of local amenities add everyday convenience and long-term appeal.
Buyers should note a number of material considerations: the tenure is unspecified and must be clarified before exchange; the building appears to have solid brick walls with no insulation (assumed), so thermal upgrades may be required; glazing type is not defined. The area records very high crime statistics, which is an important factor for families and owners. Council tax banding and some service/maintenance responsibilities are not provided and should be confirmed.
Overall, this is a rare, large-period duplex in an affluent SW7 square that will suit a family or professionals seeking space, character and proximity to top schools — provided the buyer is comfortable addressing building thermal performance and clarifying tenure and security implications.
