Built to Brave British Weather

Crafted using premium Swedish redwood and engineered tongue and groove cladding, the 4ft x 20ft Apex Shed provides superior weather resistance, preventing rain, wind, and damp from affecting your stored belongings. The innovative interlocking timber panels create a tight seal, dramatically reducing the risk of water ingress — perfect for safeguarding garden tools, bicycles, or seasonal furniture.

Customisable Window Options for Natural Light

Enhance your shed’s functionality with flexible window placements, designed to maximise natural light while maintaining security. This adaptable design ensures the shed is bright and practical, whether you use it for storage or as a hobby space.

Superior Construction for Long-Lasting Strength

Unlike conventional overlap cladding, our sheds feature robust 12mm tongue and groove panels paired with a fully framed 38mm x 50mm timber structure. The double-nailed cladding and pressure-treated floorboards elevated on bearers create an exceptionally stable, resilient building. This shed is built to endure, supporting even heavy equipment with ease.

• 12mm Swedish Pressure Treated Tanalised Redwood Tongue & Groove Shiplap for walls and roof
