Hillingdon · housing and retrofit
Hillingdon’s north is classic Metro-land. In Ruislip, George Ball built the Manor Homes estate from 1933 to 1939 on land bought from King’s College, Cambridge, and the area’s population rose from about 6,000 in 1911 to almost 48,000 by 1939.
Ruislip-Northwood was also one of the first places in England to adopt a statutory town planning scheme under the 1909 Act, approved in 1914.

Local considerations
What tends to shape retrofit here
- Hillingdon lists more than 30 conservation areas, including Ruislip Village, Ruislip Manor Way and Eastcote Park Estate
- 1930s homes usually have cavity walls – check whether they have already been filled
- Hipped roofs and rooms in the roof need careful insulation and ventilation
- Bay windows and wall junctions benefit from condensation-risk checks when insulating
Conservation area rules, Article 4 directions and listed building controls are set by the local planning authority and can change. Check the current position with Hillingdon Council before finalising external changes.
