Covering St Albans
Alongside St Albans, we also cover Harpenden (5 miles to the north), Hatfield and Hemel Hempstead.
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.
From first call to completion
- Send us the details. Give us a postcode, a rough idea of size and some photos, by phone, form or the guide price tool.
- 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.
