Our Extension Services
Every type of home extension managed end-to-end across Bristol and the South West.
Single-Storey Rear Extensions
The most popular way to add space — we handle everything from planning groundworks and foundations through to the finished interior.
Double-Storey Extensions
Add significant living space on two levels. We manage the full structural build including foundations, frame, roof and internal fit-out.
Side Return Extensions
Make use of the narrow side passage to create a wider, more open ground floor. Ideal for kitchen-diners and open-plan living.
Wrap-Around Extensions
Combine a rear and side return extension for maximum ground-floor space. Full project management from groundworks to completion.
Groundworks & Foundations
All foundation types — strip, pad and raft — excavated and poured by our own groundworks team before the build begins.
Structural Steelwork & Frames
RSJ installation, structural openings and steel frame erection coordinated as part of the wider extension project.
Roofing & Weatherproofing
Flat and pitched roof construction, insulation, guttering and weatherproofing to make the extension watertight before internal works begin.
Internal Fit-Out
First and second fix carpentry, plastering, flooring, kitchen and bathroom installation — all coordinated in-house to complete the extension.
