Skip to content Based in Northampton, we’ve delivered hundreds of projects across the county and beyond, winning a reputation for tidy sites, honest communication and finishes that last.
Most homeowners already know a loft conversion is the smartest way to gain more space. But what stops them isn’t the idea—it’s everything they’ve heard can go wrong: confusing drawings, unclear timelines, builders who disappear halfway through, spiralling costs, or a room that just doesn’t feel like it belongs.
At L.D. Design & Build, we remove that guesswork completely, handling every stage of your loft conversion in-house—from initial design and structural engineering, to planning, building control, and full fit-out. There are no handovers, no conflicting contractors, and no “you’ll need to find someone else for that.” It’s one team, one timeline, and one clear plan—right from day one.
“Les and him team were amazing. We had a two storey extension built – taking about 7 months in all. Les has a team who can take on all aspects of the build – and a long list of contacts for any jobs that needed a specialist (windows, gas etc). The quality of the build has been amazing – especially the detail of the finishing – tiling, plastering.”
We don’t just build lofts that add space—we build lofts that work: proper headroom, smart storage, natural light, clean lines, and finishes that match the rest of your home. Whether it’s a dormer, hip-to-gable, or full wraparound conversion, we design each project to feel like it was always meant to be there—not an afterthought in the attic.
And because we’ve delivered dozens of loft conversions across Northamptonshire, we know what passes, what doesn’t, and how to avoid surprises. We’ll tell you early if your loft is viable, guide you through permitted development rules (or handle planning if needed), and make sure you know exactly what to expect at every stage.
If you’re ready to gain a bedroom, office, or living space—without the stress that usually comes with it—we’ll make it simple, seamless, and built to last.
Our multidisciplinary team of builders and architects builds loft conversions, extensions, bespoke homes and full renovations across Northamptonshire, Beds, Herts, Leics and London.
