In the first decade of the 19th century two brothers, Sir Charles and Walter Burrell, each commissioned John Nash to design a new house for their neighbouring estates of Knepp and West Grinstead in the Sussex Weald. The houses belonged to a group of fashionable Regency Gothic "castles",; Knepp emerged phoenix-like from a devastating fire of 1904, and has recently undergone something of a renaissance in the hands of a new generation of Burrells.
