Commercial Extension in Taunton SW — Foundations for Your Extension

Commercial extension substructures are needed for any commercial extension, whether a single-storey addition or a multi-storey expansion. They suit commercial clients, developers, and main contractors who want a single point of contact for the substructure.

Typical commercial extension projects include single-storey extensions, multi-storey expansions, and office extensions.

Commercial extension construction covers the below-ground works that support a commercial extension: foundations, drainage, and groundworks. We deliver these packages from initial design through to DPC, with the engineering handled in-house. Because we design and build the substructure as one package, the extension moves without waiting on a third party, and the foundation is specified for the actual ground and the connection to the existing structure.

We assess the ground and the structural requirements, then design the substructure package. Our team constructs the foundations and drainage, carrying the work through to DPC. We coordinate with building control and the existing structure throughout.

Commercial extension substructure cost depends on the foundation type, the ground conditions, the size of the extension, and the connection to the existing structure. Access and the programme also affect cost. We provide a fixed quote within 48 hours of the site visit.

How do you connect the extension foundation to the existing building?

We design the connection based on the existing foundation and the ground. Where the existing foundation is adequate, we tie the new foundation to it. Where it is not, we may underpin or pile to create a stable connection. We assess both and design the right connection.
