This 6 x 4 Pressure Treated Shiplap Shed with No Windows from Mercia is a tried and tested design in a size that is suited for gardens of almost any size. It would be the perfect product if you have a small garden and need somewhere to securely store everyday garden items, particularly if you are low on space in your existing storage areas. Its classic apex roof design alongside a more sleek, low profile finish offered by the shiplap cladding makes for a garden building that looks right at home in any garden. Made in the UK using ethically sourced, FSC certified timber, this compact garden building has been constructed using high quality materials to provide you with a long-lasting structure.


The walls are made using shiplap tongue and groove cladding. This is an interlocking design that creates a strong and robust panel, and the lipped profile of shiplap cladding also aids water runoff, adding to the weather protection of the interior. All the timber is pressure treated, a process that offers added protection against naturally occurring rot and decay and provides extra longevity to your shed. A large, hinged single door allows for convenient access, and is secured closed with turn buttons. Ledged bracing is fitted to the rear of the door to add extra support, ensuring the door does not lose shape over time. This shed does not feature any windows for extra security, making the shed harder to break into and, of course, hiding contents from prying eyes.

A classic apex roofline provides plenty of headroom inside, perfect if you want to install standing shelves as an extra storage option. The roof and floor are made from robust OSB. This gives a floor that will stand up to everyday storage (spades, grow bags, garden tools, family bikes etc.) and a roof that provides a good barrier to the elements. Robust roofing felt, fixtures and fittings are all supplied as standard, alongside our detailed instructions, to ensure a simple and stress-free assembly process. You can also choose to put your feet up and use our optional assembly service for a quick and professional build. Our pressure treated buildings benefit from a 15-year anti-rot guarantee, as well as our 12-month manufacturer’s warranty. Just make sure to treat it with a waterproof top coat and look after it regularly, and your guarantee will be good to go!

Additional Details About Your Order

If you think that a Mercia Pressure Treated Shiplap Shed with no windows 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 product 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.

This product is supplied flat packed with instructions and all the fixings necessary to complete construction. The timber used is pressure treated, meaning that preservative has been forced into the timber under high pressure, which ensures a longer life and less maintenance. Colour may vary from images shown. You must make sure to follow all the manufacturer’s care instructions in order to maintain the validity of your guarantee – these guidelines will be outlined in the instructions delivered with your product. This will include instructions for periodically treating your timber – many manufacturers recommend Protek Paint, available to purchase from elbec in over 60 stains and colours.

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

Select a 'requested delivery date' by entering your post code 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.

Please note: Mercia Metal and Mercia Plastic 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 and Plastic sheds is identified on the product page above. Lead times are in working days (Monday - Friday) excludes Bank Holidays.

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 un-safe 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.
