Complete Modular Design and Premium Build Expertly built from superior 12mm tongue and groove cladding, on a strapping 28mm x 56mm frame, this workshop shed simply oozes class. Its completely modular design and interchangeable framed sections make it far easier to assemble than other wooden sheds and give you total flexibility over door positioning, allowing you to create the perfect storage solution for your garden. It also boasts 30% more timber than standard sheds, making it much stronger, more rigid and more durable than its competitors. Tongue and Groove Floor PLUS Roof The floor is built from premium 12mm tongue and groove too, so is perfectly equipped to accommodate your heavier items and will easily cope with regular footfall. Pressure-treated bearers allow good air circulation underneath the shed, which prevents the wood getting damp, providing another layer of protection against rot and fungal decay in this key area. The 12mm tongue and groove roof sports an eye-catching reverse apex design, which makes this shed perfectly suited for use as a workshop. It’s fitted with a high-grade, polypropylene-backed felt cover for unbeatable weatherproof protection. The high roofline offers you ample headroom and increases your garden storage options, while two diamond-shaped finials add the finishing touches to the shed's incredibly attractive appearance. Security-Enhanced Doors and Windowless Design/strong> You can gain storage-friendly access to this shed via generously sized, ledged and braced double doors. They include exterior turn buttons, interior bolts and a rim lock door latch, so rest assured that your valuable tools will remain completely safe. The shed's windowless design provides yet another layer of security by deterring unwanted attention.
