We have now designed, manufactured, delivered and fitted many of these 5ft x 18ft Apex Sheds for our wide customer base.
Stretching an impressive 18 feet in length while keeping a compact 5 feet wide, the 5ft x 18ft Apex Shed is a powerful solution for anyone needing streamlined, extended outdoor storage. Its long footprint fits comfortably along fences, garden edges, or narrow pathways, offering expansive space without consuming your entire garden.
Built for year-round use and crafted with high-performance materials, this shed is a masterclass in strength, practicality, and refined craftsmanship. Whether you’re storing power tools, sports gear, bikes, or seasonal décor, it’s built to last, even when the weather isn’t on your side.
Precision-Built to Brave British Weather
Every inch of this shed has been engineered to endure the UK’s temperamental climate. The 12mm tongue and groove shiplap cladding creates a weather-tight barrier, while the high apex roof adds vertical space and encourages runoff, preventing water pooling and internal dampness.
The generous internal layout, combined with customisable window placements using real horticultural glass, allows natural light to flood in without sacrificing security or insulation — perfect for storage and light-duty workspaces.
Materials Matter – That’s Why We Use the Best
Forget chipboard. Forget OSB. This 5ft x 18ft Apex Shed is manufactured from premium pressure-treated Swedish redwood — selected for its resilience against moisture, insects, and decay. It’s built on a solid frame that resists twisting, warping, and weakening over time.
Key Construction Features:
- 12mm Tanalised Redwood Tongue & Groove cladding
- 38mm x 50mm robust timber framework (walls, roof, floor)
- 18mm pressure-treated floorboards with integrated bearers
- 12mm T&G roof panels for enhanced rigidity
- 4mm toughened horticultural glass for windows
- 40kg bitumen mineral felt, nail-tacked for durability
- Galvanised hinges and Brenton padbolt

With its heavy-duty floor and structural stability, you can confidently store garden furniture, bikes, heavy tools, and equipment — all elevated off the ground and sheltered from the elements.
