Covering Maidenhead
Our coverage around Maidenhead (SL6) also includes Slough, Windsor and Beaconsfield.
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 do you get with 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.
- Planning application for the replacement dwelling
- Demolition and site clearance
- Reconnection of services and landscaping
What will a knock down and rebuild cost?

Do you need permission for a knock down and rebuild in Maidenhead?
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 affect a knock down and rebuild?
- 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.
- Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
Knock down and rebuild: common questions
How long does it take?
Around 36 to 60 weeks including demolition.
What happens about asbestos?
An asbestos survey is done before demolition and any asbestos is removed safely first.
Can you visit a house in Maidenhead to quote?
Yes. After a short call we arrange a site visit to measure up and agree what the design needs to do, then send a written price.
