Roof Type

This shed features a traditional apex roof design that efficiently sheds rainwater and provides increased headroom compared to pent alternatives. The roof is reinforced with a metal truss bracket and constructed from 8mm solid sheet, topped with premium green-mineral-felt weatherproof cover.

Dimensions

The shed measures 20′ x 10′ (5.96m x 3.21m), providing generous storage capacity. The apex roof design maximises internal space and allows for effective water runoff.

Construction

Built from 12mm shiplap tongue and groove cladding on a robust 28mm x 56mm frame, the shed walls are strong and weatherproof. The scalloped profile of the shiplap ensures excellent rainwater runoff, keeping the structure protected year-round.

The premium 12mm tongue and groove floor is supported by pressure-treated bearers, providing extra protection against ground moisture and easily handling regular footfall. Every component is pressure treated for long-term durability.

Compare this quality construction with other garden sheds and you’ll find the Forest Beckwood’s modular design and thicker framing set it apart.

Treatment & Guarantee

This pressure treated shed comes with a 25-year anti-rot guarantee – the longest available on the market. Because the wood is pressure treated during manufacturing, no further anti-rot treatment will ever be needed. This saves time, money and ongoing maintenance, leaving you to enjoy your shed rather than maintaining it.

Doors & Windows

Wide double doors with double-Z framing provide both strength and weather resistance whilst preventing the doors from losing shape over time. Hidden security hinges and a pad bolt keep your valuables secure. The windowless design adds an extra layer of security by deterring unwanted attention to items stored inside.

Assembly Information

The completely modular design makes assembly far easier than most wooden sheds. Smaller sections of interchangeable panels arrive with clear instructions and a full set of fixings included. The modular approach also allows you to customise door placements to match your garden layout and requirements precisely.
