As one of our most premium sheds, the 12×10 Ultimate Heavy Duty Reverse Apex Workshop Single Door is handcrafted from the highest quality European softwood. The spacious interior offers you plenty of storage space while the generous eaves will allow you to work effectively wherever you are in the building and enhance your vertical storage options. Equally impressive as an outdoor workshop, a secure space to store your heavy-duty machinery or a durable place for protecting your garden furniture and equipment from the weather, this workshop will be a reliable and hardworking outdoor building for years to come. This model features a reverse single door so the entry point is on the long side rather than the gable end.

This layout is more suited to some uses and garden designs but models with a standard gable end single door are also available. Our entire range of custom made Ultimate garden sheds and workshops is built from premium quality materials. Constructed from 12mm tongue and groove panels, the roof, walls and floor boast a reliably robust build. The sturdy floor will comfortably support the weight of your belongings and has been fitted with integral joists to provide the necessary elevation to avoid rot damage. For longer lasting protection against the elements, this shed features superior graded polyester-reinforced roof felt.

Our most resilient 44x44mm framing and cross framing has been used inside this wooden workshop to provide long lasting support for your garden building. Having undergone a superior pressure treatment, the workshop is guaranteed against rot and fungal decay for at least 15 years, subject to periodic retreatment. If you wish to paint your garden building, we recommend that you ALLOW 6 MONTHS BEFORE PAINTING PRESSURE TREATED TIMBER to allow the wood to fully cure and absorb the treatment. Paint applied any earlier may not adhere to the wood satisfactorily. Two opening windows provide your workshop with natural light and ventilation. They are glazed with toughened glass.

To complete the workshop’s superior finish it features a quality ledged and braced door, with an integral rim lock for built-in security and hung with heavy duty galvanised hinges. We recommend building your workshop on a hard, flat surface such as decking or concrete. You can add Life Extending Floor Supports to your order. These are installed between your hard surface (such as slabs or concrete) and the floor joists of your outdoor building’s floor. The bearers provide increased protection from damp and, therefore, rot by allowing air to circulate as well as increasing the distance between the building and the ground. The result is enhanced stability and longevity for your shed.
