Set on sought-after Onslow Square, this large, newly renovated three-bedroom apartment pairs period proportions with contemporary finishes. The top-floor flat benefits from abundant natural light, high ceilings and a private roof terrace — a rare outdoor space in central South Kensington. The bespoke kitchen includes Miele appliances and a Quooker tap, and two bedrooms have en suite bathrooms for comfortable family living or high-end lettings.
Practical features include lift access to the top floor, basement storage, and the option of underground parking by separate agreement. The long lease (being extended to 990 years) removes common long-lease concerns and the flat is presented turnkey, minimising immediate maintenance or refurbishment.
Buyers should note material running costs: a high annual service charge and very expensive council tax. Heating is via a community mains-gas scheme and the building’s timber-frame walls likely lack modern insulation. The area records very high crime levels, which may affect some buyers’ priorities despite the square’s prestige and private communal gardens with tennis courts.
Overall this is a distinctive central London home for purchasers seeking period character, outdoor space and contemporary comfort in a coveted garden square. It will suit families wanting proximity to top schools, professionals needing excellent transport links, or investors targeting prime lettings, provided they factor in the service costs and local crime statistics.
