The 4 x 2 Mini Greenhouse from Mercia is made in the UK using ethically sourced FSC certified timber. The smaller size is perfect for those with a more modest outdoor space, or for people who only require a smaller greenhouse. It features an internal shelf for more space to grow a large range of produce and plants. The dream of growing your own shouldn’t just be reserved for those with the space for a full-sized greenhouse, so this product is ideal if you live in an urban setting, have a shared garden, have a small patio, or could even be a good fit for a balcony!


The rear panel of this greenhouse is constructed using heavy-duty tongue and groove boards. This means that the boards locking together to create a premium, strong, and hard-wearing finish. Complete with robust wooden framing to support the cladding internally, this building offers a rigid and long-lasting structure. Fitted with UV resistant styrene, this allows maximum light into the space whilst remaining a safer, shatterproof option over traditional glass panels – this crucial especially if it will be sited in a cramped space or a busy garden where accidents can happen. No floor is supplied with the greenhouse to ensure water can drain easily after you watered plants inside. An opening roof/lid allows for easy access to anything you are growing inside and also provides the opportunity for ventilation during the warmer months. Wide-opening double doors allow front access to the Mini Greenhouse, and a handy interior shelf is included to help with Greenhouse organisation.

Robust fixtures and fittings are supplied as standard, alongside our detailed instructions and our manufacturer’s recommendations, to ensure a simple and stress-free assembly process. Optional assembly is available if you would prefer to sit back, relax, and have your greenhouse built for you. All of our buildings come with an anti-rot guarantee, to ensure your garden building looks great and lasts the test of time. This building comes with a conditional 10-year anti-rot guarantee as well as a 12-month manufacturer’s warranty. Annual re-treatment is required to maintain your building and the anti-rot guarantee.

Additional Details

If you think that a Mercia Mini Greenhouse 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 Mini Greenhouse is supplied flat packed with instructions and all the fixings necessary to complete construction. The timber used is dip treated, which means it has been pre-treated with a base coat in a brown, industrial product. Please be aware that the colour may vary from any pictures shown. Dip treatment coats the surface of the timber and protects it during manufacture and transit, so you must apply a suitable water-based top coat yourself to ensure your anti-rot guarantee remains valid. 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 – Mercia, the manufacturer, recommends Protek Paint, available to purchase from elbec in over 60 stains and colours.

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