Summary - Flat 3, 46, Onslow Square SW7 3NX
2 bed 1 bath Apartment
Spacious Grade II‑listed two‑bedroom with terrace and private garden squares in South Kensington.
Approximately 1,485 sq ft — unusually large two‑bedroom first‑floor apartment
Set within a Grade II‑listed stucco terrace on Onslow Square, this extraordinarily large two-bedroom first‑floor apartment (approx. 1,485 sq ft) combines striking Georgian and Victorian period detail with rare outdoor space in central South Kensington. High ceilings, Ionic columns, ornate cornicing and an elegant full‑width terrace create a sense of gracious living and excellent natural light. Two private garden squares and a residents’ tennis court provide peaceful green space rarely found in central London.
The plan centres on a generous front reception with marble fireplace and full‑width terrace access, a well‑appointed kitchen, a rear principal bedroom with a large bay and bespoke storage, plus a second bedroom that can double as a study or second sitting room. Practical points include a separate WC, one family bathroom, and access via stair or a charmful grill‑fronted lift.
Important considerations: the building’s Grade II listing means any alterations will be restricted and may require specialist consent and cost. The property shares a community heating system and appears to have solid brick walls (likely without modern cavity insulation), so energy efficiency improvements could be limited and costly. Annual service charges are high at approx. £16,500 and council tax is very expensive — factors to budget for alongside the purchase price. The lease has around 165 years remaining and the ground rent is a peppercorn.
This apartment will suit buyers seeking a prestigious, characterful central London home with exceptional private outdoor and communal green space — ideal for families or downsizers looking for a tranquil, landscaped setting close to museums, top schools and South Kensington station. It also offers strong long‑term appeal in an affluent, low‑crime neighbourhood, but purchasers should be comfortable with listed‑building constraints and the higher running costs.
