Extension Foundations in Taunton SW — Built for Your Extension, Not Assumed

Extension foundations are needed for every home extension, rear extension, side return, and commercial extension. They suit sites with restricted access, weak ground, and any project where the foundation must be matched to the conditions rather than assumed.

Typical extension foundation projects include rear extensions on terraced properties, side returns, two-storey extensions, and commercial extensions where the foundation must be engineered for the ground.

Extension foundations are the structural base for a home or commercial extension. The right type — strip, raft, piled — depends on the ground conditions, the loads, and the access. We assess all three and specify the foundation that suits the actual site, then construct it through to DPC. On restricted access sites we use compact rigs to reach positions standard rigs cannot.

We assess the ground, the loads and the access, then design the foundation type. Our team constructs it — whether strip, raft or piled — and carries the work through to DPC. On restricted access sites we mobilise compact rigs to reach the pile positions.

Extension foundation cost depends on the type required, the ground conditions, the size of the extension, and the access. Restricted access sites may require compact rigs, which affects cost. We provide a fixed quote within 48 hours of the site visit.

Do extension foundations need to match the existing house foundations?

Not always. The new foundation must be engineered for the ground and the loads, and it must connect properly to the existing structure. Where the existing foundation is shallow or on weak ground, we may specify a deeper or piled solution for the extension. We assess both and design the right connection.
