Design & Build in Horsham
Design and build is a project delivery approach where one contractor is responsible for both developing the design and constructing the project, giving the client a single point of accountability for cost, programme and quality rather than coordinating separate designers and contractors.
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
Design & Build in Horsham: FAQs
Do you provide design & build 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.
What is the difference between design and build and a traditional contract?
In a traditional route, you appoint an architect who designs the project and administers a separate contract with a builder. In design and build, one contractor is responsible for both the design development and the construction, giving a single point of accountability for cost and programme.
Do I still get an architect-quality design under design and build?
Yes. Design and build does not mean a lesser design service — it means the design and construction responsibility sits with one team. We work with qualified designers and, where useful, can introduce you to independent architects within the design-and-build process.
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.
