At LXM, we provide fully managed basement design and build services, specialising in everything from media rooms and home gyms to utility areas and self-contained living spaces. Our technical capabilities make us particularly suited to these complex, below-ground projects.

We handle all structural work, including excavation, underpinning, tanking, and waterproofing, using industry-leading systems to ensure the space remains dry, safe, and compliant. Our qualified electricians, plumbers, and heating engineers take care of all services, while our design team ensures optimal lighting, ventilation, and layout for your new living area. Every aspect is carefully coordinated for longevity and performance.

Basement works require a high level of professionalism and risk management, and our commercial construction background gives us an edge. With LXM, you benefit from robust planning, meticulous execution, and transparent communication throughout. We help London homeowners unlock valuable new floorspace with confidence and style.
