Sporting clean, contemporary lines and exceptionally thick walls, the 11x15 Palmako Martin Premium (88mm) Nordic Shed (3.3m x 4.5m) offers you exceptionally attractive and unbeatably robust garden storage. Expertly built from 88mm Nordic spruce, fine-sawn tongue and groove cladding, with added wind braces, this superb garden shed is far more robust, durable and insulated than any standard wooden shed. Both the floor and apex roof are constructed from 19mm tongue and groove cladding, the former including treated foundation joists to protect the interior from ground moisture.  You can gain easy access to this workshop shed via wide double doors, which are fitted with a laminated frame and cylinder lock, so rest assured that your valuable tools and equipment will remain secure. For even greater security, this garden shed is designed without windows. Pre-assembled wall panels, clear instructions and a complete set of fixings are all supplied to help you achieve a straightforward assembly, which is great news if you’re inexperienced at DIY. All of the parts are covered by a 5 year guarantee. *This garden shed is supplied untreated. We advise coating it with a quality wood preservative within 6 weeks of assembly, and annually thereafter, in order to prevent rot and maintain the wood’s attractive appearance. If you’d like a more individual look, you can paint this garden shed instead.* Please be advised that the roof does not include a cover as standard. Select from SBS, Charcoal Felt Shingles or Roof Felt Underlay as an optional upgrade. (SBS weatherproof roof covering is a thick, torch-on felt with an exceptionally long lifespan and outstanding weatherproof qualities. Unless you possess advanced DIY skills, we recommend hiring a professional installer. Heavy-duty Charcoal Felt Roof Shingles are a permanent weatherproof roof covering, which is attractive, easy to instal and extremely durable. Roof Underlay Felt is simple to nail on to the garden building but is only designed as a temporary solution until you have added a permanent weatherproof roof cover upgrade.)
