Philipps House (until 1916 Dinton House) is an early nineteenth-century Neo-Grecian country house at Dinton, near Salisbury, Wiltshire, England. The house was designed by Jeffry Wyatt, later Sir Jeffry Wyatville for William Wyndham (1769-1841), and was built between 1814 and 1817 on the site of an earlier, demolished seventeenth-century house, Dinton House, which had been the Wyndham family home since 1689. The new house was also called Dinton House, and was known as this until 1917 when foreclosure proceedings were brought against Dinton House and its estate.
The house is built of Chilmark stone, a local building stone also used for Salisbury Cathedral, and Wyatt is believed to have based his design on Pythouse, some seven miles (11 km) away at Newtown, near Tisbury. The house is two-storied with symmetrically set chimney stacks and a central lantern. The main (south) front has nine bays with an Ionic portico. The rooms are planned around a spacious square hall with an imperial staircase to the first floor. The house is one of the first in England to have a central heating system installed, which was achieved by pumping hot air from a boiler in the basement into the stairwell. The house contains an impressive collection of Regency furniture and furnishings and is Grade II* listed. 
The estate was bought by Bertram Erasmus Philipps (1870-1947), a descendant of the Philipps baronets of Picton Castle (1621 creation), who renamed the house after himself. He was High Sheriff of Wiltshire in 1923. Philipps and his wife, who had no children, annually hosted the pupils from the village school for a tea party at Philipps House with sports and fireworks.
In 1936, Philipps leased the house to the YWCA as a retreat, and they remained there until 1995. Philipps moved to nearby Hyde's House, a former rectory which he had bought in 1924 and where he lived until his death. During World War II, the park in front of Philipps house was requisitioned for use by the United States Army Air Force, who erected a number of Nissen huts there. In 1943 Philipps gave the house and 250 acres (1.0 km2) of parkland to the National Trust, along with Hyde's House as well as a number of paintings owned by the Wyndham and Philipps families.
After the YWCA left in 1995, the National Trust did a thorough refurbishing of the house, which is leased to a tenant family. The house is, at present, closed to the public. The parkland that surrounds the house is still known as Dinton Park, and it also has been restored.
