An extension is one of the biggest investments you'll make in your home. Barry and Ben have managed dozens of them across Weston-super-Mare, Bristol and North Somerset — from modest single-storey rear extensions to large wraparound builds that completely transform a property.
We handle every trade ourselves — groundwork, brickwork, roofing, plastering, electrics and plumbing. No juggling different contractors, no miscommunication. One team, one point of contact, from the first brick to the final finish.
The most common extension — added to the rear or side of the property to create a larger kitchen, dining room or living space. Often includes bi-fold or sliding doors opening onto the garden. We handle everything from planning through to plastering.
Maximise your investment by adding two floors at once — typically a larger kitchen or living space downstairs and an additional bedroom or bathroom above. Significantly better value per square metre than two separate builds.
Combines a rear and side return extension into one L-shaped space — creating a dramatic, open-plan ground floor. A popular choice for terraced and semi-detached properties where the side alley is currently wasted space.
Turn your unused garage into a bedroom, home office, utility room or playroom. Usually the most cost-effective way to add usable floor space — no foundations or new roofing required. Most fall under Permitted Development.
Self-contained annexes for family members, rental income or a home office. We also take on new builds and self-build projects — managing the full build from groundwork and foundations right through to handover.
RSJ installation to knock through walls and open up your ground floor. We handle structural calculations, building regulations and the full build — from steel installation through to plastered, finished walls.
