If you always catch yourself dreaming about a quiet place to work on DIY projects in the privacy of your own garden, you should consider the 10 x 10 Mercia Premium Reverse Apex Shiplap Workshop for its functionality and high quality construction. As the smallest standard size in its range, this particular workshop is a fantastic way to maximise your useful space in more restrictive gardens, thanks to a modest footprint that fits into tighter spaces.

For anyone who wants to use their garden building for more than just storage, this 10 x 10 workshop is a far better than the average claustrophobic garden shed, with the addition of a two windows to let in plenty of light and allow air to circulate when opened. The reverse apex roof is preferred by many customers for its more contemporary look over the traditional apex roofed shed. Reverse sheds also suit particular garden layouts, as the doors are not on the gable side. The generous headroom also means that the building is comfortable to work in despite its fairly compact size. A set of double doors that can open wide means that bulky items can be accessed without any trouble, making the workshop a great solution for storing garden items. Don't forget depending on the layout of your garden the double door can be located on either the left-hand side or the right-hand side front width.


Some projects take a long time. Because we understand longevity is key when it comes to investing in a premium garden building, this workshop has walls constructed with shiplap tongue and groove cladding. The cladding uses tightly interlocking 12mm timber, to help protect against bad weather over the years, while providing a pleasing and low profile finish to the walls that looks and feels better than the overlapped timber often found on cheaper sheds. The workshop’s roof and floor matches this tongue and groove construction, creating a stable base for heavier items like benches or shelves.

The building’s strength and durability are supplemented by other features, such as windows made from robust styrene. This material is shatterproof, making it a safer alternative to glass when it comes to the potential accidents that occur in a bustling garden environment – especially when younger family members are around. A raised window allows ample natural light to enter while you work, and leaves room underneath for any work benches or shelves you want to position against the same wall. The doors are supplied with a hasp and staple which can be locked with your own padlock, and for improved security the doors are ledged and braced with strong ‘Z’ shaped bracing.

Please note: some images may show the workshop decorated with accessories/furnishings these are for display purposes only. These are not included with your purchase.


This product is supplied flat packed with instructions and all the fixings necessary to complete construction. The Mercia Premium Shiplap Apex shed has a ‘modular’ design, which has many advantages. It means that the wall panels of the shed are manufactured in smaller parts, making handling and assembly easier as well as increasing the overall strength of the building.  You've the option of our manufacturer's installation service if you still feel putting the shed together is not the job for you.  We advise against arranging for a third party to install the building before it's been delivered and you've checked that all parts are present, as we cannot be held liable for any third-party costs.


The shed is supplied untreated except for a factory applied base coat.  This base coat may differ in shade across parts. This dip-treated product requires treatment immediately after assembly, and thereafter annual re-treatment to protect against rotting. There is a 10 year anti-rot guarantee from Mercia, dependant upon the building being treated annually with a wood preservative and a waterproof topcoat.  Our manufacturer recommends Protek Royal Exterior wood paint to protect your shed, you can select your colour choice from the paint options on this page.  Alternatively, if you don't see a colour you like, elbec offer the full range of Protek paints to personalise your garden building.  Click here for the full range of Protek Royal colours.
