This small garden shed may be discreet in its windowless design, but the high-quality materials Mercia has included in its construction ensure it is up to the job when it comes to storing items outside the home. If you are looking for a reliable and compact shed for your garden, look no further than the 4 x 6 Mercia Windowless Overlap Shed with Double Doors.



This storage shed might be small in size, but it is big on features. The strength of this shed comes from its high-quality timber walls; 7mm overlap cladding uses horizontal and overlapping timber boards that have a rustic charm. The timber has been dip-coated for all the protection needed against damp or insect infestation during transit and assembly. Once your shed is complete, you will need to add a wood preservative to get the most out of your timber in the coming years. (Protek produces high-quality wood paints that are perfect for this job, and are the brand we use on our own show site.) All of the timber used in this shed is FSC certified and sourced from sustainable forests. 

The double doors of this overlap shed are well-suited to storing larger items, from bicycles to lawn mowers, and keeping these doors sealed against the elements can be done with the simple turn of the door catch. To ensure the doors will be functional in future years, they have been ledged for extra strength. This matches the robust 28mm x 28mm internal framing used throughout the interior of the shed. 

Meanwhile, the floor and roof of the shed feature a solid sheet board material that is resistant to water damage and has a great uniform strength. Beneath the floor, this is backed up by joists, whereas a mineral roofing felt covers the roof and improves its durability. 


Additional Information

All of the parts and fixtures needed to assemble your shed at home are included with your flat-packed shed. Detailed and easy-to-follow instructions are also included. A 10-year anti-rot guarantee is provided by the manufacturer, assuming you follow the basic guidelines for looking after your shed with some care. We predict it will take one or two days to complete your shed, and it will be far easier with an extra pair of hands.
