Construction
This 4Life overlap wooden shed has 7mm overlap cladding with straight cut boards for a stylish finish, allowing effective rainwater runoff and natural timber movement with the seasons. The floor is 12mm solid timber, considerably stronger than regular shed flooring, on pressure treated bearers for extra protection against ground moisture. With 30% more framing than standard wooden sheds, this build delivers exceptional structural strength.
Treatment & Guarantee
The timber is pressure treated to prevent rot and backed by Forest’s 4Life 25-year anti-rot guarantee, the longest available on the market. This means the wood will never need retreating, saving you time and money over the shed’s lifetime.
Doors & Windows / Security
The double doors feature double Z framing for added strength to prevent warping, plus hidden security hinges and a hasp and staple plate (padlock not included). The fully modular design allows market leading flexibility in door placement, and the windowless design deters unwanted attention while keeping the shed looking practical alongside other garden storage solutions.
Assembly Information
The fully modular design makes assembly far easier than most wooden sheds, arriving in smaller sections of interchangeable panels. Clear instructions and a full set of fixings are included with your shed.
