Spanning two combined buildings and enjoying an unusually wide footprint, it looks directly south across the square's manicured communal gardens, with tall sash windows drawing light deep into the interior.

The sense of width and openness is immediately apparent. The principal reception room stretches across more than 20 feet, its polished timber floors and high ceilings creating a quietly impressive setting for both relaxed living and entertaining. With the gardens framed beyond the windows, it feels calm and composed, the kind of room that works just as well for an intimate dinner as it does for a larger gathering.

Opposite, the kitchen and breakfast room is smartly arranged and well equipped, with integrated appliances and generous storage. Its position across the hall allows the apartment to function effortlessly as a home for entertaining, with a natural flow between cooking, dining and the living room.

The principal bedroom sits quietly to one side of the plan, a generous and well-balanced room with excellent storage and an en suite bathroom. Two further double bedrooms are positioned along the opposite wing of the apartment, each well proportioned and served by a second bathroom, creating a layout that works equally well for families, guests or a study and guest suite combination. Throughout, the apartment has a reassuring sense of space, privacy and practicality that is rarely found in lateral period homes.

Residents benefit from a live-in porter, immaculately maintained common parts and a large passenger lift, with an external storage units on the lower ground floor provide valuable additional space.

Outside, Onslow Square remains one of South Kensington's most cherished garden squares. Residents enjoy access to its beautifully landscaped communal gardens, with open lawns, winding paths, seating areas and a children's play space, as well as a more private garden area featuring a floodlit tennis court. With the museums, restaurants and boutiques of South Kensington and Knightsbridge close at hand, and excellent transport links nearby, this is lateral London living at its most refined.
