Entering directly through a private front door, a rare feature for a property of this kind, you are welcomed into the raised ground floor, where all the principal living and entertaining spaces are thoughtfully connected. The reception room is particularly impressive, with high ceilings, intricate cornicing, decorative wall mouldings, an ornate fireplace and large sash windows overlooking the garden square. Spanning approximately 2,111 sq ft, the home offers generous proportions across four floors, with a well-considered layout that separates the principal entertaining spaces from the bedroom accommodation.

Double doors lead through to a separate dining room, creating a wonderful flow between the two spaces, ideal for both everyday family living and entertaining. The kitchen sits towards the rear of the floor, with contemporary cabinetry, marble worktops and integrated appliances, alongside French doors opening directly onto a shared patio.

The lower ground floor is home to two generously proportioned bedrooms, both with built-in storage, and two bathrooms. One of the bathrooms also opens onto a small courtyard.

Occupying the first floor, the principal bedroom suite is one of the home's standout features. The double-aspect bedroom has beautiful proportions, an elegant fireplace and French doors opening onto a private balcony overlooking the gardens of Onslow Square. A separate dressing room and spacious ensuite bathroom, complete with a bathtub and separate shower, create a well-appointed principal suite. The bathroom also has access to a second balcony.

A fourth bedroom occupies the second floor, providing additional flexibility for family living, guests or a home office.

Outdoor space is a particular highlight of the home. In addition to the balconies and shared patio, a private terrace accessed from the half landing overlooks the gardens to the rear, offering another space for outdoor seating and entertaining.

Residents also have access to the award-winning communal gardens of Onslow Square, among the largest private garden squares in the borough, with expansive lawns, mature trees, landscaped flowerbeds and shaded pathways.

Onslow Square is one of South Kensington's most recognisable addresses, known for its elegant white stucco terraces and beautiful garden setting. The Natural History Museum, Victoria and Albert Museum and Royal Albert Hall are all nearby, alongside the boutiques and restaurants of Knightsbridge and the King's Road. South Kensington Underground station is within walking distance, with connections via the District, Circle and Piccadilly lines.
