Product Details

The Power 16x4 Apex Summerhouse gives you real flexibility during installation. Door panels fit into either end of the building, so you choose the orientation at the point of assembly. Face the entrance toward your best garden aspect or position it to catch morning light. That choice is yours.

We fit a lot of summerhouses, and the 12mm shiplap tongue and groove boards cut cleanly and sit tight once assembled. The 44x28mm pressure treated frame gives the structure a firm base to build from. Toughened glass windows measuring 1620mm x 457mm flood the interior with natural light. The Premium SuperFelt roof covering, with its polyester backing and bitumen coating, handles British weather reliably. A mortise and tenon door with a press lock and key keeps the building secure. Every panel arrives dip treated, so no pre-treatment is needed before first use. The 10 Year Warranty covers the build from day one.

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.
