For construction in Hertfordshire, we handle the structural work and everything that follows it. Typical projects include:

Hertfordshire is our home county. We work most often in west and central Hertfordshire, from Tring and Berkhamsted through Hemel Hempstead, St Albans and Watford to Hatfield and Welwyn Garden City. Homes across Hertfordshire include new town housing in Hemel Hempstead, Stevenage and Hatfield, Victorian terraces in the market towns, 1930s Metro-land homes in the south-west and period cottages in the villages.
Victorian and Edwardian terraces share walls with their neighbours, so structural work is planned around party wall notices from the start. 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.

Most construction projects in Hertfordshire 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 Hertfordshire are decided by the district or borough council for your address, such as Dacorum, St Albans, Three Rivers, Watford, Hertsmere or Welwyn Hatfield. Parts of Hertfordshire are within a conservation area, where some permitted development rights are reduced and extra care over materials is expected. Much of the countryside around Hertfordshire 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.
Construction in Hertfordshire needs a builder you can trust with structure, safety and budget. This is what you get with us:
“Once the team have finished you would never know they have been there with all rubbish removed and everything left clean and tidy.”
Yes. We're based in Hemel Hempstead and work across Hertfordshire, most often in the west and centre of the county. For construction projects in the far north or east of the county, call us on 01442 976 112 to check.
Often it will. Steel beams for a loft or knock-through usually bear on the party wall, and rear extensions dig near the neighbour's foundations, so Party Wall Act notices are usually needed 1 to 2 months before work starts.
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.
Yes. We build bespoke new homes, starting with a consultation on layout, specification and finishes. A new house needs full planning permission from the local council and Building Regulations approval, and we build to the approved drawings. Much of the land around Hertfordshire is Metropolitan Green Belt, where new homes face strict planning tests.
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.
We work across the area, including construction in Hemel Hempstead, construction in St Albans, construction in Watford, construction in Harpenden, construction in Berkhamsted, construction in Hatfield, construction in Welwyn Garden City, construction in Stevenage and construction in Hitchin.
