Welwyn Garden City is the second garden city, founded in 1920 by Ebenezer Howard and known for its neo-Georgian architecture and the Parkway. Homes in Welwyn Garden City include neo-Georgian houses, interwar homes and post-war estates.
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. Conservation area status in parts of Welwyn Garden City means demolition, extensions and roof changes face tighter controls, so we plan around them early.

Most construction projects in Welwyn Garden City 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 Garden City are decided by Welwyn Hatfield Borough Council. Parts of Welwyn Garden City are within a conservation area, where some permitted development rights are reduced and extra care over materials is expected. In Welwyn Garden City, the Estate Management Scheme adds its own consent for many external changes, separate from planning permission.
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.
Construction in Welwyn Garden City needs a builder you can trust with structure, safety and budget. This is what you get with us:
“An excellent service where all works were cleared up daily. A clean site is a safe site and whilst the building works were carried out I continued to live in my flat.”
Yes. Welwyn Garden City is about 11 miles from our base in Hemel Hempstead and sits well within the area we cover, along with nearby Digswell and Welwyn.
Often, yes, if the plot allows. A two-storey side extension always needs planning permission, and the design has to work with the existing hipped roof and the neighbouring house.
Usually, yes. Many post-war houses have a load-bearing wall between those rooms, and it can be replaced with a steel beam designed by a structural engineer and approved under Building Regulations.
Yes. We build bespoke new homes, starting with a consultation on layout, specification and finishes. A new house needs full planning permission from Welwyn Hatfield Borough Council and Building Regulations approval, and we build to the approved drawings.
Yes. Removing a load-bearing wall needs a structural engineer's calculations for the new beam and Building Regulations approval. We prop the structure safely, install the beam on padstones and make good, so the room is ready to decorate.
If the work affects a shared wall, or you dig foundations within 3 metres of a neighbour's building (6 metres in some cases), the Party Wall etc. Act 1996 applies. You must serve notice: 2 months before work on a party wall and 1 month before excavations.
We take on everything from internal alterations and single-storey extensions to double-storey extensions and complete new homes. No job is too big or small, so tell us what you're planning and we'll arrange a free visit.
