A new Walpole Avenue and Starrock Green Conservation Area was created by RBBC on 6 March 2024. A comprehensive paper, including RBBC's reaction to comments received to its consultation, can be found on the RBBC website. Chipstead's third Conservation area was created by Reigate and Banstead Borough Council despite vocal opposition from some local residents. RBBC concluded that much of the area had valuable Arts and Crafts style buildings that warranted protection. The new Conservation Area comprises much of Walpole Avenue and part of Coulsdon Lane - an area of early 20th century houses mostly designed by George Blair Imrie. RBBC concluded that It was not only the houses that contributed to the character but also their associated gardens with their trees, shrubs and hedges.
