Covering Hemel Hempstead
Hemel Hempstead sits 5 miles west of St Albans, with Berkhamsted 5 miles to the west and St Albans 5 miles to the east.
Homes in the East of England
The East of England has a large stock of post-war and modern estate housing alongside period homes in market towns, which makes garage conversions, single-storey extensions and loft conversions popular.
What does a knock down and rebuild involve?
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
- Asbestos survey, demolition notice and service disconnections
What will a knock down and rebuild cost?
Typical ranges for knock down and rebuild. Ground conditions, access and specification move the final figure, which we fix in writing before work starts.
| Knock down and rebuild | Guide price |
|---|---|
| Demolition and site clearance (total) | £15,000 to £35,000 |
| Rebuild, standard specification (per m²) | £2,100 to £2,600 per m² |
| Rebuild, good specification (per m²) | £2,600 to £3,100 per m² |
| Rebuild, high specification (per m²) | £3,100 to £3,700 per m² |
How is a knock down and rebuild approved in Hemel Hempstead?
English projects need planning clearance from the local council, building regulations sign-off from building control, and party wall notices where the work is on or near a shared boundary. We prepare and manage all three.
This needs full planning permission from the council.
What can change the price or programme?
- A replacement dwelling is usually zero-rated for VAT where the old house is demolished completely to ground level.
- You will need somewhere to live for most of a year.
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.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
What people ask before starting
Is VAT charged on a knock down and rebuild?
Usually not on the new house, if the old one is demolished completely and the new building is a qualifying dwelling.
