Listed 14 Sept 2026 · price reduced 16 Oct 2026 · Kensington and Chelsea
An expansive, unmodernised four-bedroom maisonette located in the prestigious Onslow Gardens, offering an exceptional opportunity for renovation to create a truly bespoke residence. With a generous floor area of approximately 2,369 sq ft, the apartment is arranged across the raised ground and lower ground floors of a handsome, stucco-fronted Grade II listed Victorian building.
Upon entering the property on the raised ground floor, the building contains only two other flats, one of which has lateral access from the neighbouring property, ensuring a sense of privacy. The apartment features a spacious bay-fronted reception room, which is characterised by a striking ceiling height of 3.84 metres, accented with ornate period cornicing. Adjacent to the reception room is a dining room that leads to a separate kitchen with direct access to a terrace, ideal for al fresco dining and entertaining.
An unusually wide staircase descends to the lower ground floor, where the principal bedroom is discreetly positioned at the rear, offering generous integrated storage and an en suite. Two further spacious double bedrooms are also located on this floor, one with access to the terrace and the other with an en suite. Additionally, a flexible single bedroom/study also has direct access to the terrace. The lower ground floor benefits from excellent natural light, high ceilings, and ample hallway storage.
