When it comes to the amount of sheer space offered by a garden building, it is hard to do much better than 10 x 6 Mercia Windowless Overlap Shed without compromising on quality. This excellent storage shed has all the room you could need to store gardening equipment, bicycles, and much more. A 7mm timber cladding will help to keep the elements off your stored items.


Despite the simple design of this shed, plenty of the features in design and materials have been chosen with care to ensure you have the best possible experience storing items in your garden.

The roof and floor of the 10 x 6 Mercia Windowless Overlap Shed feature a tough solid sheet board, chosen for its excellent water resistance that will help keep your items dry. Timber floor joists beneath the floor help raise it above the ground and create additional strength that is helpful for storing heavier items. Meanwhile on the roof, mineral roofing felt offers protection from the elements and some rustic charm.

The characterful walls of this shed make use of a rough sawn timber cladding, with overlapping horizontal boards positioned to divert rainfall away from your stored items. This 7mm overlap cladding features FSC certified timber sourced from sustainable forests, and is dip-treated to give customers a good level of initial protection for their shed while it is being built. When complete, we advise adding to this protection with a high-quality wood preservative to ensure your timber doesn't fall prey to damp or insect infestation. Protek has an impressive range of treatments that can be added to your order through elbec, a brand who we trust enough to use it on the garden buildings at our Nottingham showsite.

Additional Details

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. In order to receive the full 10-year anti-rot guarantee on your shed, it is necessary that you treat the shed with a timber preservative prior to or shortly after construction. 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.
