Basement Build in Taunton SW — From Design to DPC

Basement builds are needed where a property requires additional below-ground space, whether for living accommodation, storage, or plant. They suit residential and commercial projects where a basement is being added to an existing or new building.

Typical basement build projects include domestic basement conversions, new residential basements, and commercial basements.

A basement build is the construction of a below-ground structure that adds usable space to a property. The basement must be engineered for the lateral earth and water pressures, with a waterproofing specification, and coordinated with the structure above. We deliver the complete package: pile design, excavation, RC walls and slab, waterproofing specification and construction to DPC. The director oversees every project personally.

We assess the ground and the structural requirements, then design the basement — piles, walls, slab and waterproofing. Our team installs the retention, excavates, constructs the RC walls and slab, and specifies the waterproofing. We coordinate with building control throughout.

Basement build cost depends on the size, the depth, the retention required, the RC specification, and the waterproofing. Access and ground conditions also affect cost. We provide a fixed quote within 48 hours of the site visit.

Can you build a basement under an existing house?

Yes. We build basements under existing properties, including basement conversions where the space is excavated beneath the house. The existing structure is supported throughout, the ground is retained, and the basement is constructed to DPC. This is work we do regularly.
