Construction

Built using top-quality materials and expert craftsmanship, this Forest Timberdale shed features 12mm tongue and groove boards throughout the walls, floor, and roof. The internal timber framing measures 28mm x 56mm – significantly thicker than standard construction – resulting in a structure that uses 30% more timber than competitors.

The completely modular design uses interchangeable panels delivered in smaller sections, simplifying the assembly process whilst allowing you to customise door and window placement to suit your garden layout. This flexibility is a key advantage when planning garden storage solutions.

This pressure-treated wooden shed is built from FSC-certified timber sourced from sustainable, well-managed forests. The pressure treatment provides complete protection against rot and decay, with a market-leading 25-year anti-rot guarantee included. No further treatment is required during this period, saving you time and maintenance costs over the lifespan of the shed.
