Steel Installation in Horsham
Steel installation is the supply and fitting of a structural steel beam, commonly called an RSJ, sized by a structural engineer to carry the load of a wall, floor or roof once an opening has been formed beneath 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.

Do you provide steel installation 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.
How is a steel beam sized for my opening?
A structural engineer calculates the required beam size and type based on the span of the opening and the load it needs to carry — including the floor or roof structure above and any additional loads such as water tanks. This is confirmed before ordering the steel.
Can a steel beam be installed without removing the whole wall?
Often yes — a beam can be installed to widen an existing opening or doorway rather than removing an entire wall, with the remaining sections of wall providing the bearing for the steel.
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.
