Set within a grand Onslow Gardens terrace, this exceptionally large two-bedroom duplex combines expansive period proportions with direct garden access. The principal reception is a classic Georgian/Victorian space: high ceilings, decorative mouldings, parquet floors, and double French doors leading to a paved patio and the communal garden, creating a rare indoor–outdoor feel in SW7.
Arranged over ground and lower-ground levels, the layout suits a couple or small family seeking generous rooms and flexible space. The lower ground houses a substantial principal bedroom with ensuite and patio access, a further bedroom with ensuite, a dressing room/study with overhead skylight, and a useful utility room. The fitted kitchen and guest WC are practical for everyday living.
Ownership is secure: share of freehold with a very long lease (971 years). The location is outstanding for South Kensington amenities, transport and specialist schools, with fast broadband and excellent mobile signal. There is no flooding risk and the property sits in a very affluent, inner-city neighbourhood.
Considerations: the annual service charge is high (circa £10,014) and council tax is described as quite expensive. The building dates from before 1900 with solid brick walls likely uninsulated and double glazing of unknown age, so future energy-efficiency upgrades may be desirable. Overall this is a character-rich, spacious home that balances prestige and genuine central-London convenience.
