In 1888, the Sumner family sold the estate to Stuart Rendel, later Lord Rendel. He had extensive changes made to the fabric of the house. Rendel was mainly his own architect but he also employed his nephew by marriage, Halsey Ricardo, and commissioned Reginald Blomfield to build the Music Room. Rendel coloured and gilded Adam's ceilings, embellished the staircase with rococo decorations and switched the main entrance of the house to the east. Rendel also commissioned Gertrude Jekyll to design the gardens which contain a parterre. Lord Rendel's grandson, Harry Stuart Goodhart-Rendel, who was an architect and British Army officer, inherited the house in 1913. He passed the estate to the National Trust in 1945.
