Terrace House Extension Foundations in Taunton SW — Built for Tight Sites

Terrace extension foundations are needed for any extension to a terraced property, particularly rear extensions with restricted access. They suit homeowners and builders who want a single point of contact for the foundation on a tight site.

Typical terrace extension projects include rear extensions, side returns, and two-storey extensions on terraced properties.

Terrace house extension foundations are the structural base for an extension to a terraced property. The foundation must carry the extension loads, be specified for the ground conditions, and be connected to the existing structure — all on a site with restricted access. Because we design and build in-house, the foundation is engineered for the actual ground, the connection, and the access, using compact rigs where standard rigs cannot reach.

We assess the ground, the existing structure and the access, then design the foundation specification. Our team constructs the foundation — using compact rigs on restricted access sites — and carries the work through to DPC. We coordinate with building control throughout.

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