Domestic Construction across London
LXM specialises in high-end loft conversions that unlock your property’s hidden potential. Whether you’re looking to add an extra bedroom, a home office, or a luxurious master suite, our loft conversions are crafted to maximise space, natural light, and long-term value. We offer a full design-and-build service tailored to your roof type, lifestyle, and local planning constraints.
Our experienced team manages everything from structural steelwork and dormer installations to insulation, electrics, plumbing, and premium finishes. We are well-versed in permitted development rights and can guide you through planning permission if required. With engineers and architects in-house or via trusted partners, we ensure your conversion is not only beautiful but also structurally sound and compliant.
We’ve delivered loft projects across period homes and newer builds alike, always respecting the character of the original structure. Whether it’s a sleek modern extension or a traditional dormer conversion with bespoke joinery, LXM ensures a stunning result delivered on time, with minimal disruption to your daily life.
