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 do you get with 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
  • New foundations, structure and full fit-out
  • Reconnection of services and landscaping

Planning and building rules in St Albans

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.
  • Asbestos is common in post-war houses and must be removed by licensed contractors where required.

  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. Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
