Why Choose Us?
How Our Start-to-Finish Build Process Works
We manage your garden room project from the initial concept to the final handover, acting as your single point of contact. The process begins with a detailed site survey to assess the land and access requirements in your Haslemere garden. From there, we undertake all necessary groundworks to ensure a level, stable foundation that prevents future settling or moisture issues. Our team handles the steel frame erection, external cladding, and roof installation, followed by the internal finishing touches. By overseeing every stage, we eliminate the need for you to coordinate multiple contractors, ensuring a smooth and efficient timeline.

The Benefits of Industrial-Grade Garden Buildings
Choosing an ER3 Group LTD build means investing in true durability. Unlike flimsy kit-builds, our garden rooms are constructed with robust frames that offer exceptional structural longevity. We utilise high-performance insulation to ensure your garden office remains comfortable during the coldest Haslemere winters and the warmest summer months. Our choice of weather-resistant cladding and premium EPDM roofing guarantees that your investment is fully protected against the elements. These buildings are designed to serve as functional, year-round living or workspace extensions.
