Single Storey
Two Storey
Build upwards and outwards together. Bedroom above, kitchen below. Maximises space without eating into the garden. Requires stronger structural work, deeper foundations, proper engineering throughout.
– OUR PROCESS
Design & Approvals
Once drawings are prepared, engineers appointed, and planning approved, we manage the build start to finish, handling all approvals and final certification.
Foundations & Build
Ground prepared, foundations poured, walls built, roof completed. Structure goes up solid before we touch any internals.
Services & Internals
Wiring, pipes, insulation, boarding. Windows in, floors down, walls plastered. Property becomes watertight and ready for finishing.
Completion & Handover
Final fittings installed, decoration complete, floors finished. Building control signed off, snagging cleared, keys ready.

Work runs daily without disappearing to other jobs. We deliver your project before taking on the next large project.
Snagging cleared before final payment. Building regs signed. You get keys to a finished job, not a list of things we'll come back to.
