Building in and around Witham
Local Builders You Can TrustWitham sits on the River Brain in the Braintree district of Essex, which matters the moment you start thinking about planning: it is Braintree District Council you will be dealing with, not Chelmsford or Maldon. The town mixes period homes, post-war estates and modern developments, and with the A12 and the mainline station on the doorstep it is a place where well-built home improvements hold their value.
Belvia is a construction company, not a one-trade outfit. We manage structural work, multiple trades and Building Control under one roof, which means steel goalposts for open-plan living, NICEIC-certified electrics, Gas Safe plumbing and properly insulated, watertight finishes that meet current U-values. Whether you are extending, reworking a tired ground floor or building from scratch, you deal with one team throughout, with weekly photo updates as the job moves.

Planning in Witham (Braintree District Council)
Planning for homes in Witham goes through Braintree District Council. Three things worth knowing before you start:
- Permitted Development covers many single-storey rear extensions and loft conversions without a full application, but PD rights are often removed on newer estates (parts of Maltings Lane and other recent developments) by planning condition. Check your deeds before assuming PD applies.
- The older town centre around Newland Street carries extra controls, and period or listed properties need a more careful approach.
- Building Regulations apply whether or not you need planning, and structural work, drainage, electrics and insulation all have to be signed off.
We handle Braintree District Council applications and Building Control as part of the job, so you are not left navigating it alone.
