Work will see the former Holiday Inn on Cromwell Road in Kensington become the Forum Hotel with all  903 guestrooms and public areas re-fitted.

The job is scheduled for completion in 2027 and will see significant structural enhancements, replacement of the existing two-storey rooftop plant area, and a new rooftop extension featuring a panoramic bar and restaurant.

Ardmore will also oversee the replacement of existing windows and cleaning of the facade, and will install new curtain walling on the ground floor and rooftop extension.

Additional infrastructure improvements include the installation of new lifts, as well as completely new mechanical and electrical plant and equipment.

New features will include a luxury spa, pool, gym, and multiple dining venues, as well as external enhancements such as a publicly accessible garden square.

Ardmore director James Byrne said: “We are thrilled to work alongside GP Hotel Forum Propco Limited on this landmark refurbishment in the Royal Borough of Kensington and Chelsea. Together, we are committed to transforming this iconic building into a world-class hotel.

“We’ve assembled an experienced team to deliver this project to the highest standards of quality and safety. Ardmore has a proven track record in high-profile refurbishments across London, and we look forward to bringing these plans to life.”

The new project builds on Ardmore’s portfolio of iconic refurbishments which includes some of the world’s best hotels such as the recently completed Raffles Old War Office (OWO), The Ned, and Ten Trinity Square.
