Beaton restored the house and grounds and entertained lavishly. Guests included actors and artists such as Tallulah Bankhead, Lady Diana Cooper, Ruth Ford and Lord Berners; artists Whistler, Salvador Dalí, Christian Bérard and Augustus John and stage designer Oliver Messel painted murals in the house, and Dalí used it as the backdrop of one of his paintings. Little remains of the Beaton-era interior design, although in the "circus room", which once contained a Whister-designed bed shaped like a carousel, one mural of a lady on a circus horse remains, painted during a hectic weekend party when all guests wielded paintbrushes.
Beaton's lease expired in 1945, when to his great disappointment he had to leave. Hugo Vickers, Beaton's biographer,suggests that Beaton never got over the loss of Ashcombe.
