Roof Type

This shed features a traditional apex roof design that efficiently sheds rainwater and provides additional headroom. The roof is reinforced with a metal truss bracket and built from 8mm solid sheet, topped with a top-quality green-mineral-felt cover for complete weatherproof protection.

Dimensions

The shed measures 20 feet x 10 feet (5.96m x 3.21m), making it spacious enough to function as a garden workshop or substantial storage facility. The apex roof design maximises internal headroom for comfortable movement and use.

Construction

This wooden shed is expertly constructed from 12mm shiplap tongue and groove cladding mounted on a robust 28mm x 56mm frame. The shiplap’s scalloped profile provides excellent rainwater runoff and weatherproofing. The floor is made from premium 12mm tongue and groove boards, supported by pressure-treated bearers to protect against ground moisture and handle regular footfall.

The modular design comprises interchangeable panels, making this shed significantly easier to assemble than conventional wooden garden sheds. The modular approach also allows customisation of door and window placements to suit your garden layout.

Treatment & Guarantee

This pressure-treated wooden shed comes with an unbeatable 25-year anti-rot guarantee – the longest on the market. No further anti-rot treatment will ever be required, saving time and maintenance costs. The timber is sourced from sustainable, well-managed forests and FSC® certified, ensuring environmental responsibility.

Doors & Windows

The wide double doors can be positioned in different locations to suit your garden orientation. They feature double-Z framing for added strength and are fitted with hidden security hinges and a pad bolt to keep your valuables secure (padlock not included).

Eight 3mm acrylic windows provide abundant natural light and are completely shatterproof, lightweight, and resistant to fading or discolouration from UV exposure.
