Why Choose Us?
How We Build Your Bespoke Garden Studio
Our process begins with a detailed site survey to assess the layout and ground conditions of your property. We prioritise proper site clearance and heavy-duty groundworks to ensure a stable foundation for every structure, preventing the settlement issues often seen in lighter builds. Once the foundation is prepared, our team erects the structural framing using proven methods, followed by high-quality insulation and weather-resistant external cladding. We manage every stage of the build, including the installation of doors, windows, and internal finishes, ensuring your garden room is ready for immediate use.

Who We Are
Navigating Planning Permission and Building Regulations
Understanding the regulatory landscape is essential for any outdoor project. While many garden rooms fall under Permitted Development Rights, we provide expert guidance to confirm whether your specific site in Southwick requires full planning permission. We ensure all electrical and structural work adheres to current UK Building Regulations, giving you confidence that your investment is fully compliant and safe. Our experience with local authority requirements across West Sussex and Adur means we can navigate the red tape on your behalf, avoiding unnecessary delays.
