Construction

Built from premium 12mm tongue and groove boards, this Timberdale shed features construction that’s renowned for strength, style and weathertight qualities. The 28mm x 56mm internal framing uses 30% more timber than standard sheds, making it significantly stronger. The completely modular design means the shed arrives in smaller sections of interchangeable panels, simplifying the assembly process whilst allowing you to customise door and window placement.

The solid 12mm tongue and groove floor is fitted with pressure-treated bearers that provide extra support and create an effective barrier against ground moisture. This construction method ensures the floor easily handles regular footfall whilst maintaining structural integrity.

Treatment & Guarantee

The pressure-treated timber requires no further treatment after delivery, saving time and money over the shed’s lifespan. Forest backs this quality with a market-leading 25-year anti-rot guarantee. All timber is FSC-certified, ensuring it’s sourced from sustainable, well-managed forests.
