Horsham's town centre retains a historic core of timber-framed and Georgian buildings around the Carfax and Causeway, surrounded by Victorian villas, interwar suburbs and newer developments on the town's edges. The surrounding villages and countryside sit close to the South Downs, which shapes both the property styles and the planning context for extension and renovation work.

Property styles in Horsham
Horsham has a strong stock of period cottages and Victorian villas in and around the town centre, alongside 20th-century family housing in the surrounding estates and larger detached homes in the outlying villages. Extension and loft conversion potential varies significantly between the historic core and the more recent suburbs.
Planning considerations
Horsham District Council is the local planning authority. The town centre, including the Causeway, is a conservation area with a number of listed buildings, meaning alterations to visible elevations, windows and materials are more tightly controlled. Some outlying villages also have their own conservation area designations, which we check before advising on likely planning routes.

How do I know what size boiler I need?

Is Horsham town centre a conservation area?
Yes, the historic core around the Carfax and Causeway is a conservation area with a number of listed buildings, which affects what changes can be made without planning permission or listed building consent.
