At Brit Home Design & Build, we specialise in complex basement conversions that unlock the hidden potential beneath your property. Basement projects are among the most technically demanding construction works, requiring expert structural engineering and failsafe moisture protection. Whether you are looking to create a home cinema, private gym, or additional living suite, our team delivers subterranean spaces that are dry, bright, and structurally superior.
We manage the entire structural process, including complex underpinning, temporary works propping, and the installation of reinforced concrete and steelwork to ensure property stability.
Our specialists install multi-stage waterproofing systems—including Type C cavity drain membranes and dual sump pump systems—to provide a lifetime of protection against groundwater.
We navigate the complexities of Basement Impact Assessments (BIAs), planning permissions, and Party Wall Agreements, ensuring your project is fully compliant with local authority requirements.
Our team manages the complete basement development process — from initial excavation and structural underpinning to advanced waterproofing and internal fit-out. Using high-performance materials and precision-engineered drainage solutions, we transform dark, damp spaces into high-quality, climate-controlled living areas that feel indistinguishable from above-ground floors.
We deliver high-stakes basement construction projects with a focus on structural precision and geological safety. Excavating beneath an existing property requires meticulous planning and engineering expertise to manage soil pressure, water tables, and the weight of the existing structure above.
Our experienced team oversees every technical stage, from the bulk excavation to the installation of failsafe waterproofing and modern internal finishes. The result is a spacious, well-ventilated, and moisture-free environment that significantly increases the square footage and market value of your property.
We deliver technically superior basement conversions with a focus on structural safety and long-term flood protection.
Our structural approach ensures the total stability of your home during and after the excavation process, using industry-leading propping and underpinning techniques.
We design redundant waterproofing systems that combine physical barriers with mechanical drainage to ensure your basement remains dry regardless of external conditions.
From the first shovel in the ground to the final light switch, we manage every trade and regulatory hurdle to deliver a seamless, ready-to-use living space.
We deliver professionally managed basement conversion projects that create high-quality, habitable spaces within existing property footprints. From structural alterations and moisture protection to construction and completion, every stage is handled with precision to achieve maximum space, comfort, and long-term performance.
We provide clear and detailed pricing for basement conversions, reflecting the technical complexity of excavation and waterproofing while ensuring excellent value for such a significant property investment.
All basement works are carried out in strict compliance with UK building regulations, fire safety standards, and structural codes, ensuring a safe, stable, and fully insured addition to your home.
Our basement designs incorporate high-performance thermal insulation and energy-efficient climate control systems to maintain a stable internal environment while minimising energy consumption.
Every detail is carefully executed, from the precision of the structural steelwork to the seamless integration of natural light wells and high-end internal finishes, ensuring a premium subterranean space.
