The hotel will welcome guests into all its public areas, restaurants and event spaces from December 4 as well as a newly renovated and enlarged spa.
The Mandarin Oriental Hyde Park will later reopen in its entirety next spring, unveiling new guest rooms and suites, including two penthouse suites.
At its height, around 120 firefighters across 20 fire crews attended the blaze at the hotel in William Street, Knightsbridge, on June 6, with footage from the scene showing flames cascading through the roof of the building.
While no one was hurt, the hotel was forced to close its doors.
In August, Mandarin Oriental pledged to retain all 600 members of hotel staff, some of whom are currently on temporary transfer to other Mandarin Oriental properties, while refurbishment work takes place.
Of its revamped spaces, New York designer Adam D. Tihany has overseen the redesign of the hotel’s “next-generation” Spa at Mandarin Oriental, London area.
The new spa features 13 individual treatments rooms, an Oriental Suite with two massage beds and a Rasul water temple, a room designed for traditional Chinese Medicine consultations and treatments, a Bastien Gonzalez Pedi:Mani:Cure Studio and two additional beauty rooms providing a series of express treatments.
Mandarin Oriental said its lobby and reception area had been “transformed” using contemporary materials juxtaposed with more traditional finishes, “to blend seamlessly with The Rosebery’s nature inspired décor”.
Two Michelin star restaurants, Dinner by Heston Blumenthal and Bar Boulud, London will open for lunch and dinner service from December 4.
Bar Boulud, London will relaunch with executive chef John Barber whose menu will feature dishes with a British contemporary twist on French classics. A Christmas and New Year menu will also be available.
Dinner by Heston Blumenthal will reopen with chef Ashley Palmer-Watts at the helm showcasing a new selection of dishes. The restaurant’s meat fruit will make a comeback, featuring a festive twist with a plum jelly rather than the traditional mandarin jelly.
Meanwhile, Joyce Wang has “carefully restored original décor and furnishings" to blend with the latest technology in the hotel’s event spaces The Loggia, The Ballroom, The Asquith and The Balfour.
