Covering Horsham
Our coverage around Horsham (RH12) also includes Crawley (7 miles to the north-east) and Horley.
Homes in the South East
The South East has a lot of 1930s and post-war semi-detached housing, well suited to rear extensions and hip-to-gable loft conversions, alongside period properties in conservation areas that need a more careful design.
What is a knock down and rebuild?
We assess whether rebuilding is better value than extending and renovating, prepare the planning application for the replacement dwelling, manage the demolition notice and asbestos survey, then build the new home. The process runs much like a new build once the old house is cleared.
- Feasibility: rebuild versus extend and renovate
- Planning application for the replacement dwelling
- New foundations, structure and full fit-out

Planning and building rules in Horsham
In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.
This needs full planning permission from the council.
What should Horsham homeowners check first?
- A replacement dwelling is usually zero-rated for VAT where the old house is demolished completely to ground level.
- Planning policy on replacement dwellings varies, especially in green belt and countryside.
What happens after I enquire?
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- Site visit. We walk the plot or existing house, look at access, levels, services and boundaries, and talk through what could be built.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
