Groundworks
The part of the build you never see again — which is exactly why it has to be right.
Everything above ground depends on what happens below it. Our in-house groundworks team delivers foundations, drainage, slabs and external works across Bristol — for our own projects, for homeowners, and as packages for builders and developers who need a groundworks partner they don't have to babysit.
We run groundworks two ways. Groundworks-only: we deliver the below-ground package — excavation, foundations, drainage, slab — to your drawings and programme, inspection-ready, then hand over a clean site to your superstructure team. Groundworks-plus-superstructure: we carry on upward, taking the build through masonry, structure and weathertight, one accountable team from dig to roof.
Recent delivery includes the complete below-ground and structural package for a new two-storey home in Brislington — excavation and foundations in winter ground, drainage, slab, then blockwork and the full roof structure. The same team, start to finish.
For developer clients: we quote from drawings with itemised inclusions, keep inspection records clean, and invoice against valuations of work carried out. Send us your site plans and programme and we will tell you quickly whether we are the right fit for the package.

“Would 100% recommend Wilson and Cole Developments. They completed a rear extension and remodel of the downstairs of our Victorian terrace which we are thrilled with. From start to finish of this significant job we felt confidence in Dan and his team, who were professional, friendly, had integrity…”
“I can highly recommend Wilson & Cole. They did some complicated renovation work for me that involved wall stitching, replacing ceiling beams and roof struts, and a creative arrangement to put in a flat floor where it was previously rather banana shaped. They were adaptive and open to ideas, and the…”
Asked and answered
The questions this page usually raises.
Groundworks-only or the full package — how do we choose?
If you have your own superstructure team, take groundworks-only and we will hand over inspection-ready. If you want one team accountable from dig to weathertight, the combined package removes the riskiest handover in construction — the one at damp-proof course.
Do you work for other builders?
Yes — builders, developers and main contractors. Send drawings, programme and site constraints; you will get an itemised package price and straight answers about capacity.
