Building Services That Transform Homes and Lives

Your home should work for you — not the other way around.
Whether you’re running out of space, living with outdated layouts, or dreaming of a complete transformation, K&G Developments has the expertise, the team, and the commitment to make it happen. With over 40 years in the trade and a complete in-house service covering every aspect of building work, we’re the partner you can rely on for exceptional results, delivered on time and without the stress.
House Extensions
Thinking of moving house to get more room? The stamp duty alone could fund a stunning extension. More and more homeowners are choosing to extend rather than relocate — and for good reason. You keep your postcode (crucial for school catchment areas), avoid the upheaval of moving, and add significant value to your property in the process.
We specialise in single-storey and double-storey extensions, including kitchen extensions, rear extensions, side returns, and wraparound designs. Every project begins with a comprehensive site survey and detailed consultation to understand how you use your home and what you need from the new space. We handle everything from initial drawings through to building control sign-off, and we work closely with architects and structural engineers to ensure your extension is not only beautiful but structurally sound and future-proofed.

Loft Conversions
Your loft is more than just storage space — it’s an opportunity. Whether you need an extra bedroom, a home office, or a playroom for the kids, a loft conversion offers one of the best returns on investment of any home improvement project. We manage the entire process, including structural calculations, dormer or Velux installations, staircases, insulation, electrics, and full finishing. The result? A brand-new, fully functional room that feels like it was always meant to be there.

Full Home Renovations
Older properties have charm, character, and often a lot of untapped potential — but they also come with challenges. Whether you’ve bought a fixer-upper or you’re ready to breathe new life into your family home, our renovation service covers everything from rewiring and replumbing to new kitchens, bathrooms, flooring, plastering, and complete internal reconfigurations.
We take particular pride in working on period and traditional properties, where sympathetic restoration and modern upgrades need to work hand in hand. We respect the bones of the building while making it fit for 21st-century living.

Retrofit Insulation & Modernisation
Energy efficiency isn’t just a buzzword — it’s a necessity. If you live in an older property, chances are it’s haemorrhaging heat and costing you a fortune in energy bills. Our retrofit insulation service includes cavity wall insulation, loft insulation upgrades, floor insulation, and secondary glazing solutions. Combined with modern heating systems and ventilation, you’ll see a dramatic improvement in comfort, running costs, and your home’s environmental impact.

New Builds
Building from scratch gives you the ultimate freedom to create exactly what you want. Whether it’s a self-build family home, a garden annexe, or a small development project, K&G Developments brings the full spectrum of trades under one roof. We coordinate architects, engineers, building control, and every stage of construction so you don’t have to. You get one point of contact, total transparency, and a build that’s delivered to the highest standards — no cutting corners, no subcontractor roulette.
