How we build your bespoke garden studio
Our process is designed to be seamless and stress-free. We begin with a thorough site survey to assess the landscape and drainage requirements in Southwick. Once the design is finalised, our team handles the groundworks and foundation pouring, ensuring a solid base for your structure.

Who We Are
Does my garden office require planning permission in West Sussex?
Navigating local regulations can be complex, but our team at ER3 Group LTD simplifies the process. While many garden rooms fall under permitted development, larger structures or those located in specific designated areas may require formal planning permission from the Adur District Council. We ensure every build complies with current UK Building Regulations, focusing on structural integrity, thermal efficiency, and fire safety. We guide you through the red tape so you can focus on your new professional environment.

The benefits of steel frame garden rooms
Choosing a steel frame or reinforced structure for your garden office offers unparalleled durability compared to traditional timber methods. Our builds provide excellent load-bearing capabilities, meaning your office is resistant to the elements and built to last for decades. These structures are fully insulated to provide a comfortable working environment throughout the changing seasons, preventing damp and cold spots. By opting for a turnkey service, you avoid the administrative burden of coordinating multiple tradesmen, as our team handles the entire build sequence from start to finish.
