What is a Modular Glass Extension?
A modular glass extension is a revolutionary building system, proudly manufactured in the UK, that creates stunning, light-filled living spaces up to five times faster than traditional methods. Up to 60% more carbon efficient than a standard brick wall, with zero waste in production and minimal site water usage.
At Room Outside, our modular glass extensions are individually designed and pre-engineered. Patented wall panels made from a fusion of steel, timber, and super-insulation exceed Building Regulation standards. With slimmer profiles for more light and up to 15% extra floor space compared to brick build, your design feels brighter, smarter, and truly bespoke.
