When size matters, go for this extra-large super-secure workshop. Crafted from top-quality wood and with double doors and lots of room inside, the XL Workshop Shed is just the job for those who need a lot of room to work or get creative. This extra large model with a range of generous sizes available, each benefiting from extra high eaves height, is the ultimate versatile outdoor space. Its superior grade tongue and groove shiplap cladding epitomises this garden shed by emphasising rigidity and security. This 12mm finish shiplap cladding comprises selected European softwood, protected with a red cedar water based treatment. The roof of the XL Heavyweight Workshop is covered with a layer of heavy duty green mineral felt for further protection.

Internally, ultra strong rounded four corner framework and a heavy duty roof truss provides further strength to this fantastic shed. The Workshop has been designed to allow the customer to choose which side of the building they require their stylish windows to be positioned during assembly and large full height double doors offer easy access. Tough, durable and resilient, this XL Workshop is designed to last the distance.

It is essential that this garden shed is assembled strictly in accordance with the instructions supplied on a firm and level base constructed from a suitably durable material. The garden shed should also be treated shortly after assembly and then annually thereafter with an appropriate high quality preservative and all glazing units must be sealed, inside and out, with silicone or other water tight sealant.
