One Sloane Opens its Doors

We first got involved in this exciting project just off Sloane Square in 2016 when building owner Cadogan Estate, asked us for our recommendations on how best to take the building consisting of a series of vacant apartments and transform it into a prime destination hotel.

Reviewing the changing floor levels and warren like nature of the existing building, we proposed that the historic façade, originally crafted in 1889 by architect Edwin Thomas Hall, was retained, and an additional sixth floor with its own cupola added, but all internal structure was removed. The recommendation was accepted and we brought the team together to deliver the project, a collaboration between the world-renowned hotelier Costes, revered designer Francois-Joseph Graf and the 300 year old Cadogan Estate. The UK delivery team of architects RSA, structures HTS, MEP design – PSH consulting, QS’s TTPP and contractor McLaren, worked to deliver a shell and core that was then to be finished and dressed by Parisian based interior designer Francois Joseph Graf.

In terms of Graf’s inspiration, the Guestrooms are a selection of mouldings, wallpapers and aesthetics from the Victorian Arts & Crafts movement with influences in the Anglo – Japanese taste which is evident in some of Graf’s furniture choices, but also influenced by Edward William Godwin and Charles Rennie Mackintosh (British Art Nouveau style). Light fittings throughout the hotel area mix of genuine 19TH century W.A.S Benson pieces along with faithful reproductions.

In essence it is an eclectic selection of different eras superbly blended together by Graf, creating what will undoubtedly be one of the most talked about hotels in the capital.

Having experienced the usual challenges associated with working in historic buildings attaching old construction to new, the covid pandemic and the focus on detail required to deliver a truly exceptional and unique final product, the hotel finally opened its doors to guests in summer 2023.
