Why Choose Us?
How Our Turnkey Construction Process Works
We handle every phase of your garden room build to ensure absolute structural integrity and minimal stress for you. Our process begins with a comprehensive site survey to assess ground conditions, which is crucial for laying a solid, moisture-resistant foundation. We then progress to the structural framing phase, utilising professional techniques often seen in our commercial building work to ensure your garden room is built for the long term. Finally, we manage the exterior cladding, insulation, and roof finish, ensuring your new space is weather-tight and thermally efficient. By acting as your single point of contact, we eliminate the need for coordinating multiple tradespeople.

07393 355531Frequently Asked Questions About Local Garden Rooms
Do I always need planning permission? Not necessarily. Many garden rooms fall under Permitted Development, but this depends on your property type, size, and location within Adur. We assess this during our initial consultation. How long does the build take? Because we manage the entire project from groundworks to finish, we offer an efficient timeline that avoids the common delays associated with fragmented contractors. Are your garden rooms suitable for year-round use? Yes. We use high-grade insulation and weather-resistant cladding specifically chosen for the UK climate, ensuring the space is thermally efficient regardless of the season.
