The Right Approach From the Start
The new town housing — planned and built from the late 1940s onwards across the RH10 area — was designed with garages as standard features, giving the town a very high density of integral garage properties that are now popular candidates for conversion to home offices, playrooms, and additional bedrooms.
The area is a town in West Sussex, South East England, administered by Crawley Borough Council. The postcode districts covering the area are RH10, RH11. Nearby areas include Horsham, Redhill, East Grinstead, Gatwick. A garage conversion building notice or full plans application must be submitted to the local building control authority before work begins — your contractor should manage this process.
Garage Conversion Work in Crawley and the RH10 Area
The local planning authority covers the RH10 and RH11 postcodes for planning purposes. Garage conversions in Crawley are permitted development for most residential properties — as a new town, Crawley's housing was designed with garages as standard provision and most of the residential estates are outside conservation area designations. Building Regulations approval is required. Crawley's housing has a high proportion of flat-roof garages in the 1950s and 1960s estates, which requires specific attention to insulation and roof condition during the conversion process.
