The House at Beaverbrook is due to open next week on August 15 as part of a phased opening of the property, which is set within 400 acres of countryside on the edge of the Surrey Hills.
The latest part of the project is an 18-room hotel with interiors designed by Susie Atkinson and a Japanese restaurant from Taiji Maruyama, who formerly worked at Nobu in London and also founded Kiru.
The opening of The House follows on the launch of the 11-room Garden House, which also features a cookery school, at the end of 2016.
The 19th century building was previously known as Cherkley Court and was home to Lord Beaverbrook for 50 years.
The House’s 18 rooms are named after some of Cherkley Court’s most famous guests including Winston Churchill, Elizabeth Taylor and James Bond creator Ian Fleming.
The final phase of the development is The Coach House Cottages and Spa, which is due to open later this year.
