The long-awaited transformation of London’s Admiralty Arch into a luxury hotel is now expected in 2025, following the purchase of the building by Reuben Brothers earlier this year.

Plans to convert the Grade I listed building – located at the end of The Mall and across from Trafalgar Square – were first announced just over a decade ago, and an agreement for the property to join Hilton’s Waldorf Astoria brand was unveiled in 2017.

Reuben Brothers acquired the building from previous owner Prime Investors Capital this summer, and in a press release Hilton said that the project was “accelerating” under the new ownership.

The group said that “Since taking ownership of the building over the summer, Reuben Brothers has been working closely with Hilton to upgrade existing development plans for the site, in a partnership that will see the transformation of one of London’s most notable landmarks, staying true to its heritage and refined aesthetic”.

The updated plans include an increased room count, spa facilities and a newly developed two-bedroom suite on the fourth-floor bridge at the centre of the building, which will be bookable for overnight stays and private events, “boasting the most sensational view of Buckingham Palace”.

The property will also feature a sixth floor rooftop terrace, and a second ground floor outdoor space “where guests will be able to sit overlooking St James’ Park”.

As well as the hotel facilities the converted building is expected to feature residential apartments and a private members’ club, and Hilton said that the hotel would “provide exciting restaurants and bars with world-renowned chefs, ensuring it becomes a must-visit London destination for hotel guests and non-residents alike”.

There are currently around 30 Waldorf Astoria properties worldwide, with a further 20 in the pipeline in destinations including the Seychelles, Osaka and Sydney.

Recent additions include the Waldorf Astoria Lusail, Doha, and the Waldorf Astoria Washington DC, a conversion of the former Trump International Hotel Washington DC.

Commenting on the latest update Christopher J Nassetta, president and CEO, Hilton, said:

“Admiralty Arch is undoubtedly one of the most iconic landmarks in London and we are delighted to be working with Reuben Brothers on this magnificent hotel.

“With a legacy of preserving and enhancing incredible historical buildings, Waldorf Astoria is a natural fit for this development, and Reuben Brothers’ proven track record in delivering projects of this magnitude makes them a wonderful partner.

“Together we will write the next chapter of this exceptional building’s rich story and we look forward to expanding our partnership over the coming years.”
