Roof Type

The reverse apex roof features an 8mm solid sheet construction reinforced with metal truss brackets. Covered with top-quality green mineral felt, the roof’s distinctive scalloped design ensures excellent rainwater runoff and increases internal headroom compared to standard sheds.

Dimensions

Overall size: 5.96m x 3.21m (20′ x 10′). This spacious garden shed provides ample storage capacity for most household and garden requirements.

Construction

The shed features expertly engineered construction throughout. Walls are built from 12mm shiplap tongue and groove cladding mounted on a robust 28mm x 56mm frame, ensuring durability and excellent weather protection. The scalloped shiplap profile actively channels rainwater away from the structure.

The floor consists of premium 12mm tongue and groove boards supported by pressure-treated bearers, protecting against ground moisture and easily handling regular use. This modular construction means the shed arrives in smaller, interchangeable panel sections, making assembly considerably simpler than traditional solid wooden sheds.

Treatment & Guarantee

All timber is pressure treated with Forest’s industry-leading 25-year anti-rot guarantee. This treatment means the wood never requires retreating or additional maintenance – a significant saving in time and money over the shed’s lifespan. The FSC® certified UK timber is sourced from well-managed, sustainable forests.

Doors & Windows

The wide double doors feature double-Z framing for exceptional strength and shape retention. They’re fitted with hidden security hinges and a pad bolt (padlock not included) to keep contents secure. The doors can be positioned in different locations to suit your garden layout, thanks to the modular design. The windowless configuration deters unwanted attention and maximises security for stored valuables.

Assembly Information

The completely modular design makes this shed far easier to assemble than most wooden sheds. Clear instructions and a full set of fixings are included. The interchangeable panels and flexible door placement options allow customisation to your specific requirements. A professional installation service is available as an optional extra if preferred.
