Philipps House, originally Dinton House, overlooks its picturesque village. A seat of a branch of the Wyndham family, it is a Palladian mansion, built in Chilmark stone by Jeffrey Wyatt – later Sir Jeffrey Wyattville – for William Wyndham IV (1769–1841) of Dinton and Norrington. Inside, its finest feature is a great ‘Imperial’ staircase. In 1917 William Wyndham (1868–1950) sold it to Bertram Philipps (1870–1947), younger son of the family of the Philipps baronets of Picton Castle, Pembrokeshire, and High Sheriff of Wiltshire in 1923. In 1936 Bertram let the house to the YWCA (who remained there until 1995), whilst he lived in Hyde House. In 1943, when the park had been requisitioned for use by the American Air Force, he gave the park with Philipps and Hyde Houses to the National Trust, together with some paintings including: 'View of a Ruined Bridge by a Quay', by Jan Asselyn and 'A Beggar', an overpainted picture after Georges de La Tour.
