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.

Booking Delivery

You will be required to book your delivery date at the time of placing your order (except for Metal Shed). Our 'Request a Delivery Date' service is available to the majority of areas and you'll find that the majority of the UK postcodes are FREE but some areas may incur a delivery surcharge and some postcodes are not covered at all. Select a 'requested delivery date' by entering your postcode in the 'Request a delivery date' section above. You will also be notified at this time if your area incurs a surcharge or delivery is not covered in your area.

Prior to Delivery

On the morning of your delivery date, you'll be sent an update by text with an estimated 2-hour delivery slot (this update can only be provided where a mobile number has been supplied on the billing address section at the time of checkout) together with a link to the manufacturer delivery portal where you'll be able to track your order.

Please note: Mercia Metal Sheds ONLY - your order is delivered by a courier you will not be notified prior to the delivery. If you are not in on the day of the delivery you will be carded and asked to contact the courier to arrange a new mutual delivery date. The estimated delivery lead time for Mercia's Metal sheds is identified on the product for the metal shed. Lead times are on working days (Monday - Friday) excludes Bank Holidays. These estimated lead times are provided by the manufacturer. Some remote areas will take a little longer.

Upon Delivery

Your order is delivered either kerbside or driveway and will be delivered on either a 3.5T, 7.5T or 18T Lorry. Unfortunately due to health and safety and insurance liabilities the driver will not be able to take your goods around to the back of your property but may upon request place the product at the side of the house if there are no access or restriction issues. We would not risk damaging your property whilst delivering a product to an unsafe location. Unfortunately, we will not be able to go through your property.

We would recommend against arranging for a third party to install the building before it's been delivered and checked that all parts are present, as we cannot be held liable for any third-party costs.


Orders with Assembly 

The lead time for our installation option is around 12 weeks from the date of order. With the installation option, the majority of orders will have their delivery and installation on separate days; there will be a small number of orders which will have delivery and installation on the same day. You will be advised by the manufacturer's installation team which category your order falls into.

Depending on the installation option for your order, you will be contacted within the delivery timescale and given a date for either delivery/assembly on the same date or a separate date for delivery and assembly.
