When size matters it is time to go for our extra-large range of secure storage workshops. With double doors and a massive internal space, the XL is just the job. You must ensure that this garden building is assembled strictly in accordance with the assembly instructions that are provided and is installed on a firm and level base constructed from a suitably durable material. The garden building should be treated shortly after assembly, both externally and internally, with a good quality wood preserver and treated with a water-resistant treatment. Treatment should be reapplied annually to prolong the life of your building. All glazing units must be sealed, inside and out with silicone or other watertight solution of your choice (not supplied). Images and photos of products are provided for illustrative purposes only. Please note that product colours can vary slightly due to the digital photography process and variations in individual user monitor settings. Features: 12mm Shiplap Tongue &
