Direct views across the private gardens form the backdrop to this beautifully proportioned three-bedroom duplex on Onslow Gardens. Set across the ground and lower-ground floors of a white stucco-fronted period building, the apartment extends to approximately 1,565 sq ft and has unusually generous entertaining space, high ceilings and a secluded patio.



The ground floor is centred on an impressive open-plan kitchen and reception room measuring more than 38 ft in length. A ceiling height of approximately 11 ft 6 in enhances the sense of volume, while tall windows draw in natural light and frame the garden-square outlook. Herringbone oak flooring runs throughout, and the streamlined kitchen is arranged around a substantial central island. A bedroom with an ensuite shower room and a guest cloakroom are also found on this floor.



Two further bedroom suites are arranged on the lower-ground floor. The principal bedroom spans more than 20 ft and has a generous walk-in wardrobe, an ensuite bathroom and direct access to the patio. The third bedroom also opens onto this outside space and is served by its own ensuite shower room.



Residents have access to the beautifully maintained private gardens directly opposite. Mature trees, broad lawns and established planting create a particularly peaceful setting in the heart of South Kensington.



Onslow Gardens is one of the neighbourhood’s most sought-after addresses, distinguished by its handsome period architecture and proximity to the shops, restaurants and cafés of Old Brompton Road and Gloucester Road. South Kensington Underground station is within easy reach, as are the museums of Exhibition Road, Hyde Park and the boutiques of Chelsea.
