Ennismore purchased the hotel last year in a deal thought to have been worth about £150 million and is now planning a “multi-million” refurbishment by designers including David Collins Studio, Timorous Beasties, Macaulay Sinclair and Goddard Littlefair.

The property-wide upgrade will ensure the Gleneagles brand “remains synonymous with luxury”, according to Sharan Pasricha, who founded Ennismore in 2011.

Pasricha also created fashionable boutique hotel brand Hoxton, which now has two locations in London and one in Amsterdam, but Gleneagles will retain a more classical luxury sensibility.

“The Gleneagles Hotel is an incredible property and beloved brand,” Pasricha said. “It is known the world over for its golf, but with 850 acres of beautiful Scottish countryside, there is the potential to do so much more with the hotel. We really want to showcase the unrivalled range of facilities we offer on the estate.”
