The 8 x 4 Mercia Premium Shiplap Pent Shed provides an excellent amount of space for all your garden essentials because it has a higher ridge height than similar pent roof sheds. It is also a flexible, modular design, so you can decide where you want to locate the windows and doors during construction. This will allow you to build the shed that best suits your garden space, whether it’s to take advantage of direct sunlight or simply to ensure your door is where you need it for easy access.


The shed walls are 12mm shiplap tongue and groove. This style of cladding is top of its class when it comes to shed construction. With the shiplap board design encouraging water run off in combination with the tongue and groove boards closing together tightly, you are given a shed that is nicely sealed away from the elements on the inside. The roof and floor are also made from 12mm interlocking tongue and groove boards. This is a quality feature that is seldom seen in sheds in this price bracket and ensures you have a roof that provides excellent weather protection and a floor with an impressive load capacity. You will also receive good quality mineral roofing felt with your shed which will provide an additional barrier to the weather.

The shed features two double windows, which allow in plenty of natural light. They are glazed in shatterproof styrene for safety and represent a safer alternative to traditional glass glazing. The door features a galvanised steel pad bolt, to which you can attach your own padlock to secure your shed’s contents. A robust framing gives the building extra strength and in addition to a 10 year anti-rot guarantee, this means you can be sure your shed will stand up to the test of time.

Instructions for assembly are provided and are designed to be easy for confident DIYers to follow. All the fixtures you will need to complete your shed are included.

Additional Details about Your Order

If you think that a Mercia Shiplap Pent Shed 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 shed 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 building is supplied dip treated for protection during manufacture and transit. You must apply a wood treatment to the exterior. Many manufacturers recommend Protek wood treatment, available from elbec in many 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. You should always follow the manufacturer’s instructions and the instructions of your chosen treatment for best results and to validate your guarantee.

Delivery Leadtimes

The estimated delivery lead time for this product is identified on the product page above. Lead times are in working days (Monday - Friday) excludes Bank Holidays. These estimated lead times are provided by the manufacturers and are not guaranteed - due to fluctuation in demand - but are provided in good faith and are representative of delivery at that time. Some remote areas will take a little longer.

Upon Delivery

Your order is delivered either kerbside or driveway and will be delivered on a 17 ton lorry (the size of a Refuse Cart). 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.

You do not need to be home for your delivery. All we ask is that you let us know via email or leave a signed note to let us know that you will not be present for the delivery. In the note please let us know where a suitable place would be to leave the building. If you leave us a note the delivery driver will ring you 30 minutes before delivery and you can inform them of where the note is or you could just leave it on your front door. You must include your signature on the note; our drivers can then take photos of the note to confirm an item(s) has been delivered.

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.

Installation Option

If you have chosen our installation option your order will be delivered as per the delivery process above you have chosen. You’ll be given a separate date for the installation. The installation option will extend your lead time by up to 10 working days.
