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
- Planning application for the replacement dwelling
- Demolition and site clearance

Do you need permission for a knock down and rebuild in Helston?
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 should I think about before starting?
- You will need somewhere to live for most of a year.
- Planning policy on replacement dwellings varies, especially in green belt and countryside.
What happens after I enquire?
- 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.
- 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.
