The Flat Pack Sheds 7ft x 20ft Apex Shed comes flat packed and includes express FREE delivery.
Experience garden storage at its finest with the 7ft x 20ft Apex Shed. It is designed specifically to endure the harsh British weather while providing ample space to organize your tools, equipment, and outdoor essentials. Combining robust construction with elegant design, this shed is engineered to protect and last.
Built to Brave the Elements
Crafted from premium tongue-and-groove cladding panels, this shed goes beyond basic garden storage. Its interlocking design strengthens the structure and creates a watertight seal, preventing rain from penetrating the walls. Whether torrential downpours or cold winds, your belongings remain safe, dry, and secure inside the 7ft x 20ft Apex Shed.
Superior Construction for Enhanced Durability
Unlike typical overlap cladding, this shed utilizes thick, pressure-treated Swedish redwood tongue and groove shiplap, guaranteeing exceptional durability. The heavy-duty floor, supported by robust bearers, allows you to store heavier items without worry. Each timber panel is double-nailed and joined with galvanized nails for maximum strength, ensuring stability throughout its long lifespan.
Thoughtful Design to Maximise Usability
The shed offers versatile window placement options, allowing you to customize natural light flow to suit your needs. The bright and airy interior enhances functionality, whether gardening, working on a hobby, or organizing your space. Plus, with galvanized hinges and secure Brenton padbolts included, security is never compromised.
Premium Timber and Quality Materials
Flat Pack Sheds is proud to use only the finest materials, refusing to settle for chipboard or OSB alternatives. Each building features:
- 12mm Swedish pressure-treated tanalized redwood tongue & groove shiplap
- Strong 38mm x 50mm framework on all walls, roof, and floor
- 18mm pressure-treated floorboards, elevated off the ground to prevent moisture damage
- 12mm tongue & groove shiplap roofing
- 4mm durable horticultural glass windows
- 40kg heavy-duty modified bitumen mineral felt, securely nail-tacked for superior weatherproofing
Additionally, the entire structure is fully framed and screwed for lasting strength, not merely stapled, which improves stability during and after assembly.
