Construction

The 20×10 shed walls are constructed from 7mm overlap cladding with straight-cut boards for a superior, stylish finish. This design ensures effective rainwater runoff and allows the timber to move naturally through seasonal changes. The 12mm solid timber floor is considerably stronger than regular shed flooring and sits on pressure-treated bearers for extra protection against ground moisture.

The fully modular design features 30% more framing than standard wooden garden sheds, delivering exceptional structural strength. Delivered in smaller interchangeable panel sections, assembly is far more straightforward than traditional wooden sheds.

Treatment & Guarantee

This pressure treated shed is backed by Forest’s unbeatable 4Life™ 25-year anti-rot guarantee – the longest guarantee available on the market. The pressure treatment ensures the wood will never need retreating, saving you time and money over decades of use. One quality shed purchase means genuine maintenance freedom.

Doors & Windows

The windowless design adds maximum security by deterring unwanted attention to stored valuables. Double doors can be installed in different positions thanks to the fully modular design, allowing you to customise placement to suit your garden layout. Doors feature double-Z framing for added strength and are fitted with hidden security hinges plus a hasp & staple plate for tool and equipment protection (padlock not included).

Assembly Information

The fully modular design makes assembly considerably easier than conventional wooden sheds. The shed arrives in smaller sections of interchangeable panels with clear instructions and a complete set of fixings included. Professional installation is available as an optional extra if you prefer not to assemble it yourself.
