Lime Plaster & Heritage in Horsham
Lime plaster and heritage restoration uses breathable, lime-based plasters, renders and mortars — rather than modern gypsum or cement products — on period and listed buildings whose solid walls need to let moisture pass through rather than trapping it.
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
Lime Plaster & Heritage in Horsham: FAQs
Do you provide lime plaster & heritage 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.
Why can't modern gypsum plaster or cement render be used on an old house?
Older solid-wall buildings were designed to let moisture evaporate through breathable materials. Modern gypsum and cement-based products are far less permeable, and can trap moisture within the wall, leading to damp, timber decay and, eventually, more extensive repair than if a breathable lime system had been used.
Do I need listed building consent for lime plaster or render repairs?
If the property is listed, works affecting its character — internal or external — usually need listed building consent, separate from Building Regulations. We check this and, where consent is needed, factor the application process into the programme.
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.
