Across the East of England, newer estates often have integral garages and room for rear extensions, while older towns have Victorian terraces and conservation areas that shape what can be built.

What is a knock down and rebuild?

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.

  • Asbestos survey, demolition notice and service disconnections
  • Demolition and site clearance
  • Reconnection of services and landscaping

Do you need permission for a knock down and rebuild in Cambridge?

Projects in England go through two separate checks.

Where work touches a shared wall or digs near a neighbour’s foundations, the Party Wall etc. Act 1996 applies.

This needs full planning permission from the council.

From first call to completion

  1. Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
  2. Site visit. We walk the plot or existing house, look at access, levels, services and boundaries, and talk through what could be built.
  3. Drawings, approvals, written quote. We prepare the design, apply for the approvals it needs, and give you a fixed price in writing.
  4. Build and hand over. Our teams build to the programme, building control inspects, and you get the completion paperwork at the end.

How long does it take?

Around 36 to 60 weeks including demolition.

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.
