Extensions & new builds
Single and double-storey extensions, garden rooms and full new-build homes — from planning through to first-fix, second-fix and beyond.
- Full structural work
- Steels, foundations, roofing
- Glazing & bi-folds
Because we run every discipline in-house, the standard set on day one is the standard you get on handover day. No sub-contractor lottery.
Single and double-storey extensions, garden rooms and full new-build homes — from planning through to first-fix, second-fix and beyond.
Whole-house refurbishments where we re-plan the layout, re-wire, re-plumb and rebuild the space from the studs out.
Hand-painted shaker and modern flat-fronted kitchens with stone or quartz worktops, integrated appliances and considered lighting.
Full bathroom installations, en-suites and wet rooms — tanking, tiling, underfloor heating and brassware.
The layer most people rush — done properly. Filled, sanded, spray-primed and hand-painted joinery, walls and ceilings.
Offices, retail units and hospitality spaces — out-of-hours working available so trading isn't interrupted.
UV-stable resin-bound aggregate drives, paths, patios and pool surrounds — SuDS-compliant, permeable and installed on properly prepared bases that outlast the surface.
New · FeaturedThe fastest-growing surface in the UK — and the one where a proper base is the difference between ten years of showroom finish and two years of cracks. We install resin-bound aggregate on correctly specified sub-bases, with hand-cut edges, permeable SuDS-compliant build-ups and UV-stable resins.






Every resin project starts with the base. The surface is only as good as what sits under it — that's why our guarantee covers the whole build-up, not just the finish.
Send the basics — we'll come back the next working day with a written quote, colour blend suggestions and an installation window.
"The drive completely changed the front of our house. Neighbours have stopped us in the street to ask who laid it. Two winters in and it still looks like the day they finished."
"They didn't cut a single corner on the base. Dug the whole thing out, laid new sub-base, and the resin went down in one continuous pour — no joints, no weeds, nothing."
"Quoted properly, priced fairly, finished on the day they promised. The colour blend they mixed for us matched the stone on the house perfectly."
"We had three quotes and 4D were the only ones who talked about drainage and the base before they talked about colour. That told us everything."
"Turned our tired tarmac into something that looks like it belongs in a magazine. Clean, quiet crew, and they swept up every day before they left."
Tell us the outcome and we'll shape the scope. Most projects touch three or four of the disciplines above.
