What Horsham Is Building

Horsham vs The National Norm

A historic district, and the data proves it.

Set Horsham's application mix against the national average and two categories stand clearly above the norm. Conservation-area works made up 5.4% of submissions against a national 1.9%, nearly 3 times the national share. Listed-building works ran at 3.8% against 2.4% nationally. Extensions, at 22.3%, were lower than the national 29.1%, suggesting the district's older housing stock limits how much owners extend versus maintain or restore.

Meanwhile, the market

Prices held steady alongside the building activity.

Building and adapting homes carried on at a healthy pace, and prices moved with it rather than against it.

Horsham's planning data reflects a district with a genuine historic character. Conservation-area and listed-building applications together run well above the national norm, a signal of how much protected and period stock exists here. At the same time, this is one of the easier councils to get permission from, with a refusal rate of just 1 in 11 against a national 1 in 8. For buyers, that combination of heritage character and a permissive council is a notable finding.
