The work is expected to begin on September 1, 2019 with a planned completion date of summer 2020. During this time, the hotel would stop receiving guests.
The extensive refurbishment project will cover all areas of the 17-storey building. Interiors will be significantly remodelled to include a redesigned guest arrival experience at the hotel lobby entrance, the creation of a celebrity destination restaurant on Sloane Street, a refreshed rooftop health club overlooking Cadogan Gardens, and a new spa, with its 20m indoor pool.
All guestrooms and suites are planned to be completely refurbished to a new level of luxury, according to a statement. The number of keys will reduce from 216 to 188 with the introduction of new Signature Suites and Junior Suites.
London-based design studio 1508 London has been appointed to work on the project.
Jumeirah Group CEO José Silva said in a statement: "We are thrilled to announce our plans for the complete refurbishment of Jumeirah Carlton Tower. This project is a significant investment in the heart of Knightsbridge and is undertaken with the greatest attention to detail. A priority is to ensure that the new Jumeirah Carlton Tower will continue to be a cornerstone for the local community as well as an undisputed leader in the luxury hospitality world. This stunning re-imagining will contribute greatly to the repositioning of Jumeirah globally."
