The modular panel design allows you to customise the placement of doors and windows to suit your specific needs.

The floor is engineered with premium 12mm tongue and groove boards mounted on pressure-treated bearers, which provide extra support and act as an effective moisture barrier against ground dampness.

The timber is pressure-treated and comes with Forest’s market-leading 25-year anti-rot guarantee. This comprehensive guarantee means you’ll never need to treat or maintain the wood, saving significant time and money throughout the shed’s lifetime. The FSC-certified timber is responsibly sourced from well-managed, sustainable forests.
