The 10 x 16 Mercia Premium Reverse Apex Shiplap Workshop - Pressure Treated boasts a generous interior space for your workshop and storage needs. The garden building’s impressive scale allows it plenty of scope for a variety of uses, such as a full garden workshop with work benches and shelving, storage for larger garden equipment, or even as an occasional office. If you have always pictured having a quiet place away from the house where you can work on DIY projects or other hobbies, this workshop has the space and build quality you need to achieve this ambition.

What sets this workshop apart from the conventional garden shed is the window, which can be opened to allow air to circulate on hot days. This is placed high enough on the wall to ensure you will have space for any desks, shelves, or work benches you might wish to install against the same wall. It is also far enough from the double doors for natural light to not be blocked even when the doors are wide open.

The 16 x 10 sizing of this workshop is the optimal size to give you far more space and functionality than the more modest 10 x 10 or 12 x 10 models, without having the colossal footprint of the 20 x 10 model. This provides excellent flexibility while keeping small enough to fit in a reasonably large garden. The reverse apex roof is preferred by many customers for its more contemporary look over a traditional apex roof shed, and the headroom provided by the generous height of its ridge and eaves also means that the building is comfortable to work in.


What sets this workshop apart from many garden buildings is the 12mm cladding that features tightly interlocked timber in its shiplap tongue and groove construction. This cladding, held firmly in place with solid 2“ x 1“ wooden framework, has an attractive low profile finish that shows off your timber in a way that traditional overlap cladding does not. This design of cladding also greatly improves the workshop’s overall strength and shields the building from the ingress of water. The workshop’s roof and floor matches this tongue and groove construction, creating a stable base for heavier items like benches or shelves.

Pressure Treatment - This shed comes pressure treated in an attractive, brown colour. Pressure treated timber has undergone a process where preservatives are forced into the timber under high pressure. This provides extra longevity and an unbeatable level of protection for the wood against rot, insects and fungus. This also means the building comes with a 15 year anti-rot guarantee.

Though pressure treated timber is well protected, customers should carefully read and follow all care guidelines supplied by the manufacturer with your building. This usually involves regular treatment with a water based treatment. The manufacturer recommends Protek Wood Treatments, available to purchase through elbec at a fantastic price.

This building is supplied flat packed with detailed instructions and all the fixtures needed to complete assembly by yourself. We recommend that you build your workshop with one or two trusted friends, or simply add the option to have your building professionally assembled by our team when you order.

Additional Details about Your Order

If you think that a Mercia Premium Reverse Apex Wooden Workshop would be perfect for you, take a look at our delivery information. If you would like any extra details, feel free to email us to discuss your order and our full range of product options, or better still, give us a call so we can find the perfect garden building to suit your needs.

Alternatively, why not visit us at our Brookfields Garden Centre showsite near Nottingham? One of our helpful advisors will be on hand to show you around or to help guide you through your order in person. Though if there is a particular garden building you would like to see, we recommend contacting us in advance to find out if we have it, or one similar, on site.

All our sheds are supplied pre-treated with a base coat to both sides in a golden brown water based industrial product (colour can vary from the picture shown) for protection during manufacture and transit. You must apply a water based top coat of your choice in order to receive the full 10-year anti-rot guarantee. Many manufacturers recommend Protek wood treatment, available from elbec in a wide variety of different colours. This will protect the timber from weathering, making it last longer. The timber treatment will need to be repeated periodically in line with the manufacturer's instructions.
