Description

This exceptional 3,618 sq ft 4 bedroom, 4 bathroom residence sits on the first floor of Knightsbridge Gate — a Grade II listed landmark originally designed in 1902 by W.D. Caröe for the Church Commissioners.

The iconic Edwardian façade has been meticulously restored, preserving the glamour and heritage long associated with Knightsbridge, while the newly created south elevation introduces stepped terraces and refined architectural detailing.

Internally, MSMR architects have transformed the building with interiors that marry historic character and contemporary sophistication. A rich palette of materials, bespoke joinery, intricate detailing and beautifully crafted stonework elevates every space. The apartment features grand principal rooms overlooking the landscaped beauty of Belgravia, a private balcony, separate kitchen dining room with Gaggenau appliances, a dedicated laundry room and a cloakroom.

Knightsbridge Gate offers residents an exceptional lifestyle with 24hour concierge, advanced security systems, Lutron lighting, comfort cooling and underfloor heating. Located at the gateway to Knightsbridge, the development is moments from Hyde Park, Harrods, Harvey Nichols, and the boutiques, restaurants and cultural institutions that define this world class neighbourhood. This is London living at its most refined — where historic grandeur meets contemporary craftsmanship.

Light and bright, the living spaces are inspired by the building’s historic beauty, the rich environs of Knightsbridge, and contemporary fashion, with meticulous modern detailing and an exemplary choice of materials throughout.
