More floor space for your money

Not only will the TEK panel walls of your new extension have improved thermal efficiency, but their narrow profile means your room will have a larger usable floor space than a traditional brick and mortar build.

Render finish

One of the most popular finishes for the Garden Buildings and Guardian Home Extension is a simple render finish. Rendering allows the extension to blend seamlessly into an already rendered home, and you have no limitations on your paint colour choice.

Opting for a facing wall of brick will allow us to match up the bricks of your existing home and blend your new Garden Room or Extension seamlessly. Whether a plain brick wall or with pattern detailing your new extension can tie in as needed.
