Roof Type

This apex roof design features 8mm solid sheet construction reinforced with a metal truss bracket. The roof is fitted with premium mineral-felt covering to ensure complete weatherproof protection. Smooth-planed barge boards and attractive finials add to the stylish appearance, whilst the high roofline provides generous headroom inside the shed.

Dimensions

Measuring 15′ x 10′ (4.48m x 3.21m), this large garden shed offers substantial storage space. The generous dimensions combined with the high apex roof create excellent headroom and storage options for tools, equipment, and garden furniture.

Construction

The 4Life overlap wooden shed features 7mm overlap cladding with straight-cut boards for a stylish finish. This construction method ensures effective rainwater runoff and allows the timber to move naturally with the seasons.

The floor is constructed from 12mm solid timber – considerably stronger than regular shed flooring – and includes pressure-treated bearers to provide extra protection against ground moisture.

With 30% more framing than standard wooden sheds, this construction delivers exceptional structural strength and durability. The fully modular design means the shed is delivered in smaller, interchangeable panels for easier assembly.

Treatment & Guarantee

The timber is pressure treated to prevent rot and is backed by Forest’s unbeatable 4Life™ 25-year anti-rot guarantee – the longest guarantee available on the market. This means the wood will never need retreating, saving you time and money over the shed’s lifetime. You’ll only ever need one shed with a 4Life™ guarantee.

Doors & Windows

The double doors feature double-Z framing for added strength to prevent warping. Hidden security hinges and a hasp & staple plate keep your valuable tools secure (padlock not included). The fully modular design allows market-leading flexibility in door placement, so the shed can be customised to match your garden layout and requirements.

This windowless design adds enhanced security by deterring unwanted attention, whilst maintaining the shed’s practical and professional appearance alongside other garden storage solutions.

Assembly Information

The fully modular design makes assembly far easier than most wooden sheds. The shed is delivered in smaller sections of interchangeable panels, reducing complexity during installation. Clear instructions and a full set of fixings are included with your shed.
