Porches in Horsham
A porch is a small enclosed structure built over an entrance door to provide weather protection, additional security and storage, ranging from a simple canopy to a fully glazed and insulated room.
In Horsham, that covers Roffey, Holbrook, Littlehaven, Denne, Trafalgar, Broadbridge Heath, Southwater, Warnham, Colgate. 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.

FAQs
Porches in Horsham: FAQs
Do you provide porches across all of Horsham?
Yes, we cover the RH12 and RH13 postcode areas in full, including Roffey, Holbrook, Littlehaven, Denne, Trafalgar, Broadbridge Heath, Southwater, Warnham, Colgate.
Do I need planning permission for a porch?
Most porches fall under permitted development if the external ground floor area is 3m² or less, the highest point is no more than 3m (or 4m with a dual-pitched roof), and no part comes within 2m of a boundary that fronts a highway. Outside these limits, or on designated land, a planning application is needed.
Does a porch need Building Regulations approval?
A porch under 30m² floor area is generally exempt from Building Regulations provided it has no habitable use, though the new external door, any glazing and electrical work still need to meet relevant standards.
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.
