Building in Welwyn Hatfield: what to expect

Welwyn Hatfield is the borough that takes in Welwyn Garden City, Hatfield, Welwyn, Digswell, Brookmans Park and the Ayots. Homes across Welwyn Hatfield include garden city homes, post-war new town housing and period village properties.

Post-war houses often have internal walls that can come out with the right steelwork, opening up the kitchen, dining and living space. With 1930s semis, a hip-to-gable loft conversion and a rear extension can transform the space, and both need careful structural design. Historic cottages may have timber frames or soft brick and flint walls, so structural changes are planned around the original fabric.

What approvals does construction in Welwyn Hatfield need?

Most construction projects in Welwyn Hatfield need Building Regulations approval, and many also need planning permission. New houses always need full planning permission, while some extensions can use permitted development.

Planning applications in Welwyn Hatfield are decided by Welwyn Hatfield Borough Council. Parts of Welwyn Hatfield are within a conservation area, where some permitted development rights are reduced and extra care over materials is expected. Much of the countryside around Welwyn Hatfield is Metropolitan Green Belt. Permitted development still applies to most houses, but applications for larger extensions are judged on whether they are disproportionate to the original building.

If the work affects a shared wall or involves digging near a neighbour's foundations, the Party Wall etc. Act 1996 applies too; see our guide to the Party Wall Act and the GOV.UK guide to Building Regulations approval.

We line up approvals, structural calculations and any party wall notices before work starts; see how our build process works.
