Homes in the South West
The South West mixes stone and render cottages, Victorian terraces in the larger towns and modern estates, and many historic centres are conservation areas where materials and roof shapes are closely controlled.
What does a knock down and rebuild involve?
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
- Demolition and site clearance
- New foundations, structure and full fit-out

How is a knock down and rebuild approved in St Austell?
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. We prepare the drawings and supporting documents, submit the application and respond to the planning officer.
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 are the steps?
- Start with a conversation. A short call or the online form is enough for us to understand what you want to build.
- 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.
- We build it. Work follows an agreed programme, with inspections at each stage and a final sign-off.
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.
What happens about asbestos?
An asbestos survey is done before demolition and any asbestos is removed safely first.
Can you visit a house in St Austell 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.
