Extension Builders, Not Just Architects
We design practical layouts, handle structural work and build the extension — foundations, steelwork, roofing, bi-folds, kitchens and finishes included.
Every Extension Type
Single-storey rear extensions, side returns, wrap-arounds, two-storey extensions and garage conversions. We match the solution to your home and budget.
Planning & Building Regs Support
We advise on permitted development and planning requirements, and build to building regulations with structural calculations managed properly.
Trade Discounts on Materials
Bricks, timber, glazing and finishes supplied through trade accounts — better pricing than going retail and buying labour separately.
Our work
Extensions Built to Last
Rear extensions, side returns and wrap-arounds — designed and built by one team from foundations to final finish.
Why Extensions Overrun and Overcharge
Extension horror stories usually involve a low opening quote, unexpected groundworks, and three different contractors blaming each other when the bi-folds don't fit.
- Quotes that exclude foundations and structural steel
- No clear project manager on site
- Planning and building regs left to the homeowner
- Interior finishing quoted separately — costs spiral
We survey properly, quote the full build, and manage every trade under one roof from dig to decoration.
More living space tailored to how you actually use your home.
