shire, between the villages of Upper Basildon and Lower Basildon.
It is owned by the National Trust and is a Grade-I-listed building. The house was built between 1776 and 1783 for Sir Francis Sykes, and designed by John Carr in the Palladian style, at a time when Palladianism was giving way to the newly fashionable neoclassicism. Thus, the interiors are in a neoclassical "Adamesque" style.
Never fully completed, the house passed through a succession of owners. In 1910, it was standing empty, and in 1914, it was requisitioned by the British Government as an army convalescent hospital. It was again sold in 1928 and quickly sold again. In 1929, following a failed attempt to dismantle and rebuild the house in the USA, it was stripped of many of its fixtures and fittings and all but abandoned.
Use the main entrance from the A329.
Parking: Free, 400 yards from the mansion (buggy available).
