Covering Havant
Our coverage around Havant (PO9) also includes Waterlooville (3 miles to the north-west) and Portsmouth.
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 included in a knock down and rebuild in Havant?
Knock down and rebuild means demolishing an existing house and building a new one in its place, often a bungalow or poorly built post-war house replaced by a larger, more efficient home. Because the new house counts as a new dwelling, the build is usually zero-rated for VAT.
- Feasibility: rebuild versus extend and renovate
- Planning application for the replacement dwelling
- New foundations, structure and full fit-out

How is a knock down and rebuild approved in Havant?
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 I think about before starting?
- 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 are the steps?
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- Site visit. We walk the plot or existing house, look at access, levels, services and boundaries, and talk through what could be built.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.
Your questions answered
Is it cheaper to knock down and rebuild or renovate?
It depends on the existing house. Where a house needs major structural work and a large extension, rebuilding can be similar cost and gives a better result. We compare both at feasibility.
What happens about asbestos?
An asbestos survey is done before demolition and any asbestos is removed safely first.
