Description
Constructed from rustic overlap cladding, this 10 x 6 garden building utilises a reverse apex design to prioritise accessibility and floor space. By placing the single door centrally on the substantial 10ft side panel, the layout invites you into the heart of the structure rather than the end, ensuring that items stored in the far corners are never out of reach. The timber boards are fixed to a solid 28mm x 28mm internal frame, creating a stable shell, while the apex roofline directs rainwater away from the front and back to help resist moisture ingress. The door is reinforced with internal bracing and secured with a hasp-and-staple latch, ready for a padlock (not included).
The interior is enclosed by a floor and roof manufactured from solid sheet board, a durable material selected to bear the weight of standard garden machinery and storage boxes. To further protect your belongings, the roof is finished with mineral felt, acting as a functional barrier against the elements. The inclusion of a double window on one side of the door ensures the workspace is well-lit, making it suitable for both storage and light garden tasks. Please note that the building is supplied as a DIY kit; any shelving or accessories shown in images are for illustration purposes only.
Proudly manufactured in the UK using ethically sourced timber, this Mercia shed is an environmentally responsible choice. It arrives with all necessary fixtures and detailed instructions to facilitate assembly. To ensure the structure remains sound and to validate the conditional 10-year anti-rot guarantee and 1-year manufacturer’s warranty, it is essential to apply a high-quality timber preservative and a waterproof top coat immediately upon construction and annually thereafter.
What Makes Overlap Sheds a Good Option?
If you require a classic garden shed without the premium price tag, overlap construction is an excellent choice. The layered timber boards create a familiar rustic appearance while offering dependable storage space. Due to the straightforward manufacturing process, overlap sheds remain one of the most cost-effective building types available on the market.
Walls, Floor, and Roof
The walls are constructed from traditional 7mm overlap boards, a design that accommodates natural timber movement and aids water run-off. These boards are secured to a sturdy frame to ensure a lasting structure. The shed features an OSB (Oriented Strand Board) roof and floor; this strong sheet material is formed by compressing layers of wood strands, providing a durable and economical surface for your storage needs. The solid sheet roof is finished with a weatherproof felt cover for comprehensive protection.
Fixtures and Fittings Included
Your shed is supplied with high-grade roofing felt for reliable weather protection, along with all necessary screws, fittings, and fixings for assembly. We also include detailed instructions to help you assemble your shed efficiently and with confidence.
Choosing Between Overlap & Shiplap
In overlap sheds, the cladding boards sit one on top of the other to form the walls. This creates a timeless, rustic appearance and allows for a degree of natural ventilation, which can help to limit condensation. Because they are easy to manufacture, overlap sheds are an attractive choice for cost-conscious buyers.
Shiplap sheds are constructed using tongue-and-groove cladding that interlocks for a tighter fit. This results in improved weather protection, increased rigidity, and a smoother exterior profile. While they sit at a higher price point, shiplap sheds are a superior option for those requiring stronger construction and enhanced long-term performance.
Deciding Which to Choose:
Go for Overlap when you need:
- A budget-friendly solution.
- Standard storage space for typical garden equipment.
- Infrequent entry or light use.
- A timeless, rustic shed look.
Choose Shiplap when you need:
- Enhanced defence against wind and rain.
- A smarter, smoother visual finish.
- Regular access and ongoing use.
- Reinforced panels for longer service life.
Guarantee
Every shed is supplied with a standard 10-year anti-rot guarantee and a 12-month manufacturer's warranty, giving you long-term confidence in your purchase.
Wooden Shed Maintenance Requirements
The shed has timbers with a dip-treated base coat to protect them during transit. You must apply a preservative and waterproofing topcoat immediately after installation. Using the treatment after installation, followed by consistent annual treatment of the wooden shed, will maintain the high-quality finish and is required for the 10-year anti-rot guarantee. A 1-year manufacturer's warranty is included as standard.
Optional Upgrades
Professional Installation
This wooden shed is supplied flat-packed for self-assembly. For ultimate convenience, you can select our professional installation service. Once your order is placed, the manufacturer’s team will send a pre-installation questionnaire to confirm that your site is suitably flat and level, and that access is clear. Please note that the installation team cannot dismantle or remove old buildings. Whether you build the shed yourself or use our service, please ensure a 24-inch (60cm) clearance is left around the entire structure for assembly and maintenance.
Wooden Shed Base Kit
A solid, level base is vital for the longevity of your shed. While this shed includes a floor, the optional base kit attaches to it to provide essential support and help create a level surface. It offers a fast and simple DIY alternative to laying concrete or paving slabs. The kit consists of a robust framework made from UC4 incised timber, pressure-treated to the highest standard for permanent ground contact.
TimberArmour Pressure Treatment
Select TimberArmour pressure-treated timber for enhanced long-term durability. In this process, preservative is forced deep into the wood to help resist rot, fungal decay, and moisture, significantly reducing upkeep and extending the life of your shed. This option removes the need for immediate treatment upon assembly. While pressure treatment protects the timber against rot and decay, we recommend applying a breathable, waterproof timber treatment after installation. This helps limit moisture penetration and surface weathering, maintains the building’s appearance and durability, and ensures the guarantee remains valid.
Roof Felt Upgrade
Upgrading to superior roof felt provides your shed with stronger weather protection. This material is approximately 50% thicker than standard felt, combining a glass-fibre surface with a heavyweight bitumen base to create a tough, waterproof barrier. It is available in Dark Grey or Light Grey for a clean, durable finish.
Floor Support Pack
Extra Strength Floor Support Packs add cost-effective reinforcement to your shed floor. Fitted between standard joists (fixings not supplied), they increase stability and are recommended if you intend to store heavier items, such as lawnmowers or workshop equipment.

Make the Most of Your Shed
This compact shed is particularly valuable for smaller gardens where floor space is at a premium. It serves as an excellent dedicated home for long-handled tools, spades, forks, and potting equipment that often clutter patios or larger garages. By designating this area for your gardening essentials, you can keep your primary outdoor living areas tidy and hazard-free.
Beyond simple tool storage, the shed can be utilised to help protect seasonal items during the colder months. It offers a convenient place to store plant pots, cushions, or small garden ornaments that might otherwise suffer from winter exposure. With the addition of simple shelving (sold separately) or hooks, the vertical space within the apex roof can be optimised to store even more, ensuring every inch of the footprint is used effectively.
