Why Choose Us?

How We Build Your Professional Garden Office

Every project begins with a detailed site survey to assess ground conditions and access requirements. We start with essential groundworks and precision foundation pouring, ensuring a solid base that prevents settling or moisture ingress. Depending on your specific needs, we utilise robust steel frame construction or heavy-duty timber framing, tailored to provide maximum structural integrity. Our team handles every phase of the build, including wall insulation, weather-resistant cladding, roofing, and the final installation of windows and doors. By managing the full construction sequence, we maintain strict quality control at every stage.

Who We Are

Why Choose Industrial-Grade Materials for Garden Rooms?

Many garden structures struggle against the coastal weather patterns common in Selsey. By applying our industrial expertise, we use materials designed for longevity and thermal efficiency. Steel frame buildings offer unmatched structural stability and resistance to warping, while our professional cladding solutions ensure your space stays dry and comfortable throughout the year. Investing in an ER3 Group LTD workspace means you are getting an office engineered to the same high standards as our agricultural and industrial projects, providing you with a long-term asset that withstands the elements.
