Groundworks & drainage
Excavation, foundations, reinforced slabs, drainage alterations and soakaways.
House extensions
Extensions built properly, from the ground up.
Single and two-storey extensions across the Forest of Dean, Wye Valley and Monmouthshire, coordinated from foundations and structure through to the finished space.
One coordinated build
A practical route from plans to completion.
Forest Built manages the major stages of an extension with a trusted team and straightforward communication throughout.
We undertake groundworks, masonry, structural steelwork, timber framing, roofing, internal alterations and finishing trades. Complex access, existing buildings and unexpected site conditions are dealt with practically—not passed back to the homeowner.
