This 10 x 8 Mercia Overlap Shed with Double Doors gives the owner remarkable value for their money, with its roomy interior and solid structure that gives items the cover they need from the outdoors. Overlapped timber on the walls of this shed gives it the traditional look that many garden owners will love, and is best protected with a Protek preservative (available for order through elbec with this shed) that will complete the look of your garden with a dash of colour.


Four fixed windows make the interior of this overlap shed a bright and airy place to stand, which you will be able to do thanks to the 6'10" height of the ridge, which is the highest point of the apex roof. These are glazed with tough styrene that is virtually impossible to shatter into dangerous shards like many types of glass, perfect for busy gardens where balls or frisbees can often do damage. These fixed windows can be fitted to the side of your choice.

Perhaps the most notable feature of this shed is the set of double doors, which open up the interior in an effective manner and make storing items like wheelbarrows or lawnmowers a much simpler task. These doors are ledged and braced for improved strength, in case you want to make your shed more secure with the addition of a locking system (not included).

A fine 7mm timber is used for the cladding of this shed, which has been ethically sourced with an FSC certification to back this up. The timber is overlapped in a familiar style for sheds that helps divert water away from the interior, and has that charming rustic look. This same wood features in the internal framing of the 10 x 8 Mercia Overlap Shed with Double Doors, which is 28mm x 28mm for all the stability your shed needs to resist weather year-round.

Additional Information

To benefit from the lengthy 10-year anti-rot guarantee offered by Mercia, make sure to read the care instructions in full so that you know the actions that need to be taken to ensure your coverage remains valid. As the timber in this shed has been dip-treated, it will have some initial resilience to the elements but should be treated with a wood preservative - such as the Protek products offered by elbec - once assembled.

The 10 x 8 Mercia Overlap Shed with Double Doors will be delivered in a disassembled state with every fixture and part you need to put it together. It may help to have some experience with DIY projects when assembling your shed, but with the aid of a friend you should be able to complete the building over the course of an afternoon or two.

ALL DELIVERIES ARE DELIVERED TO KERBSIDE OR DRIVEWAY. All of our Mercia products are delivered flat packed other than fence panels (which are delivered fully constructed), direct to your home, and are supplied with a set of instructions to support assembly.

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.
