Roof Type
This reverse apex roof design enhances headroom and provides excellent rainwater runoff. The roof is built from 8mm solid sheet, reinforced with a metal truss bracket and finished with a top-quality green-mineral-felt cover to ensure complete weatherproof protection.
Dimensions
The 12′ x 8′ (3.6m x 2.61m) size provides substantial storage capacity whilst remaining manageable for most garden spaces. The reverse apex design maximises internal headroom, making it practical for standing storage of tall items.
Construction
This wooden shed features premium construction throughout. The walls are built from 12mm shiplap tongue and groove cladding on a robust 28mm x 56mm frame. The scalloped profile of the shiplap provides excellent rainwater runoff and creates a timeless aesthetic with a smooth-planed finish.
The floor is constructed from 12mm tongue and groove boards supported by pressure-treated bearers for extra protection from ground moisture. This flooring easily handles regular footfall without deterioration.
The modular design allows the shed to be delivered in smaller, interchangeable panels, significantly simplifying assembly compared to traditional garden sheds. This modular approach also permits flexible door placement to suit your garden orientation perfectly.
Treatment & Guarantee
Every component is pressure treated to resist rot. The 25-year anti-rot guarantee is the longest available on the market, meaning no further treatment will ever be required. This exceptional durability saves both time and money over the shed’s lifetime, offering true maintenance-free ownership.
Doors & Windows
The wide double doors feature double-Z framing for added strength and to prevent warping. Hidden security hinges and a pad bolt keep your valuables secure (padlock not included). The windowless design provides an additional security layer by deterring unwanted attention to the shed’s contents.
Assembly Information
The completely modular design makes assembly straightforward compared to traditional wooden sheds. Clear instructions and a full set of fixings are included. The flexible modular panels allow customisation of door placement to match your specific requirements and garden layout.
