House Extensions

About our house extensions service

House extensions are a practical way to transform a property, providing the additional floor space required for modern living without the upheaval of moving. At Design N Build, we specialise in delivering high quality extensions that integrate with your existing home. Whether you need a side extension to enlarge a narrow kitchen or a substantial double storey extension to add extra bedrooms, our team manages every stage. We work with residential homeowners looking to expand their living areas and commercial property owners seeking to increase the footprint of their assets. Our approach covers everything from the initial footings and structural steelwork to the final internal finishes. By considering the architectural style of your original building, we ensure the new addition feels like a natural part of the structure. From rear extensions that open up your home to the garden to complex wrap around projects, we provide the technical expertise needed to navigate planning and building regulations effectively.

  Modern extensions use the latest insulation and glazing standards, often making the new space more thermally efficient than the original parts of the house.
