Engineered to Brave British Weather

Crafted with premium 12mm pressure-treated Swedish redwood tongue and groove cladding, the 5ft x 20ft Apex Shed is built to resist the toughest elements. Unlike ordinary sheds, its interlocking boards form a tight seal to keep rain and damp at bay, ensuring your tools, bikes, or garden furniture stay dry all year round.

Natural ventilation and carefully designed roofing protect your stored items from moisture, making this shed a reliable fortress against wind, rain, and frost. Optional window placements add light and a touch of personal style, perfect for gardeners who also need a bright workspace.

Robust Construction for Lasting Strength

This isn’t just any garden shed — it’s built on a solid framework featuring:

• 38mm x 50mm robust framing throughout walls, roof, and floor for unwavering stability
• 18 mm-thick pressure-treated floorboards supported by sturdy bearers to withstand heavy loads without sagging
• 12mm tongue and groove roof panels covered with heavy-duty mineral roofing felt, meticulously nail-tacked for long-lasting protection
• 4mm horticultural-grade glass windows that provide clarity and durability, enhancing natural light
• High-quality galvanised fixings, hinges, and padbolts included for secure assembly and longevity

Each element is selected and assembled to give you peace of mind that this shed will endure for decades, no matter what the British weather throws.
