Product Details

The Power 20x4 Pent Potting Shed Combi delivers a practical split between growing space and secure storage. Choose a 14ft or 16ft growing section alongside either a 4ft or 6ft lockable shed. That shed section keeps tools and equipment contained and accessible. A 2028mm (6ft 6") ridge height means no planning consent is required. This unit suits both dedicated growers and occasional gardeners needing a tidy, well-organised garden setup.

Installation is straightforward, and the door panel position can be chosen at either end during construction to suit your site. Inside the growing area, full-length 2 tier staging sits at 500mm deep, giving ample surface area for potting and propagation. The 457mm x 610mm toughened glass windows admit strong, even light throughout. Every locking door is fitted with a galvanised handle and hinges. The 44x28mm frame runs throughout the structure, and 12mm Shiplap Tongue and Groove boards of slow-grown Scandinavian Softwood clad all panels. Both the 12mm floor and 12mm roof construction handle solid weight loads. The roof is dressed with Premium SuperFelt, which carries a polyester backing and bitumen coating for long-term weather resistance. All panels arrive dip treated, so the unit is ready to install directly from the crate. A 10 Year Warranty backs the build.

12mm Shiplap Tongue and Groove Panels

Enjoy the robustness of our 12mm shiplap panels, pre-treated for year-long protection and ready for further personalisation with paint, stain, or varnish to match your style.

Are Our Sheds Treated?

Our sheds come with a special protective coating on the outside. This means you can set up your shed without worrying about the weather or the elements. You have a whole year to choose a specific protective coating or paint in any color you like to cover the base coating. We do recommend treating your shed once a year after that to keep it in good condition. And if you want to change the color or repaint sooner, you can go ahead and do that too.
