London’s Chelsea neighbourhood will welcome the new One Sloane hotel this September, located at 1 Sloane Gardens just off Sloane Square.
The hotel is a collaboration between Parisian hotelier Costes, designer Francois-Joseph Graf and the 300-year-old Cadogan Estate.
One Sloane is a conversion of a former retail and residential block, with the six-year project retaining the facade of the 19th century building while adding a sixth floor with its own cupola. Interiors, meanwhile, have been remodelled by Graf and a team of artisans and craftspeople, with design features including ceiling cornices, wood wall panelling, antique chairs, mosaic tiling and chandeliers suspended from a painted stormy skied ceiling.
The hotel will also feature William Morris wallpaper and mirrors along the staircase walls, while the property also features a total of 21 carpet designs, 19 curtain designs and 50 custom-made fabrics.
The hotel’s 30 rooms and suites will feature cream English panelling on the walls, Japonisme-styled desks, restored pieces of antique furniture, stained glass windows and black-and-white photography “celebrating love and personalities connected to the area”.
The light-filled restaurant on the top floor, inspired by The Peacock Room painting by James McNeill Whistler and Thomas Jeckyl, will offer all-day French dining amid panoramic city views, antique mirrors and wooden shelves adorned with Chinese vases.
A speakeasy-style lounge will have a private entrance on Holbein Place and offer cocktails and fine wines as well as a resident DJ.
Hugh Seaborn, chief executive of Cadogan, commented:
“It is a joy to see so much of Chelsea’s exquisite architecture and rich artistic heritage reflected and celebrated throughout One Sloane – creating a truly beautiful and unique hotel which will appeal to both discerning visitors and locals alike. We have been working closely as a team for six years to realise M. Costes and Graf’s exquisite vision for their first London property and it is inspiring to see the artisanship involved at every stage. We believe One Sloane will effortlessly and immediately feel part of the neighbourhood, while bringing a fresh new energy to Chelsea.”
The Cadogan Estate has a number of existing properties in the area, including the Belmond Cadogan Hotel and 11 Cadogan Gardens, which joined luxury hotel and restaurant collection Relais and Chateaux in 2019 and launched a series of apartments opposite the hotel in 2021.
Cadogan is also in the process of transforming the 1km Sloane Street in partnership with Kensington and Chelsea Council to create a “stunning green boulevard from Knightsbridge to Sloane Square” with promises of wider pavements, a planting scheme, street furniture and enhanced lighting. The project, which costs £46 million, is set to take two years to complete.
