A complete extension build, tailored to your home

Each Guardian extension is managed from initial excavation, drainage assessment, and concrete foundations through to damp-proofing, insulation, and precise ground preparation. We construct dwarf or full-height walls with brickwork matched to your existing property, alongside insulated flooring systems for lasting comfort. We install frames in uPVC, aluminium, or timber, with double or triple glazing, including energy-efficient and self-cleaning glass options. We fit roofing systems in glass, polycarbonate, or solid tile, complete with ventilation, guttering, fascias, and downpipes. Internal finishes include plastering, flooring, electrics, lighting, and heating solutions, while doors and windows such as French, sliding, or bi-fold options are fitted with secure locking and ventilation features. We also support planning permission and building regulations, helping your project move forward without delays and resulting in a practical, welcoming extension built for year-round use.
