Anyone excited to transform an unused corner of their garden into a spacious interior that is ideal for both storage and personal projects may just have found what they are looking for with the 15 x 10 Mercia Overlap Workshop Shed. This model utilises a fantastic combination of high-quality timber construction and some thoughtful core features that make the garden building very versatile. It is often difficult to find a workshop of this calibre within its price range, which is why it is perhaps no surprise that this model is incredibly popular among DIY enthusiasts.


This workshop follows the traditional rules of creating a reliable garden shed, with a felted apex roof and unpretentious overlapped timber cladding. This 7mm cladding is dip-treated to give the wood some protection from the elements in the initial phase of its life, although we recommend the addition of a high-quality wood preservative as soon as possible to ensure the timber flourishes and lasts many years without water damage.

A sturdy 28mm x 28mm internal timber frame with extra support beams gives the structural stability needed for the larger scale of this workshop compared to many garden buildings. This also caters for the increased height of the workshop, which offers a generous degree of interior headroom due to a 7'4" ridge height (the tallest point of the apex roof).

All of this space requires plenty of available light for comfort when using the workshop; fortunately, six fixed windows are included and can be placed on the side of your choosing. This ensures you can maximise the sunlight entering your workshop based on its surroundings. These fixed windows feature transparent styrene that is lightweight yet virtually shatterproof, making it a safe option for bustling family gardens where footballs have been known to go AWOL on occasion.

The addition of a workbench in front of a window immediately produces a comfortable workspace that allows you to fall into the world of DIY projects without a problem. In addition to this, a set of double doors make entering or leaving with larger items an easier experience.

Additional Information

Upon delivery, your workshop will arrive in a disassembled state with every part and fixture needed to put the garden building together at home. Enlisting the help of a friend will be helpful in assembling your workshop, and elbec suggests allowing a day or two to complete the building depending on your prior experience with similar DIY tasks. A clear and detailed instruction manual is included with the order.

Due to the timber's dip-treatment, your workshop will have a significant degree of protection from the elements when it first arrives. However, be sure to apply a wood preservative to the exterior in due course to make certain you are following the care instructions that Mercia provide to ensure full coverage from the fantastic 10-year anti-rot guarantee.

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.
