Rear Extensions

About our rear extensions service

Rear extensions are one of the most effective ways to transform the footprint of a UK property. By extending into the garden area, homeowners can create the spacious kitchen-diners and family zones that many older houses lack. This service is equally popular for residential homes needing more room and commercial properties looking to expand their ground-floor operational space. Whether you are considering a single-storey addition or a more complex wrap around extension, these projects allow for a total reconfiguration of the ground floor. At Design N Build, we focus on creating seamless transitions between the original house and the new addition. From initial structural assessments and building regulations to the final internal finishes and flooring, we manage every stage. Our team works on a variety of project types, including modern glass-heavy extensions and traditional masonry builds that match the existing character of your home. By integrating structural engineering with architectural vision, we ensure your rear extension is both a practical upgrade and a lasting asset to your property.
