The Traditional Tall Wall Greenhouse from Mercia combines a small footprint whilst providing a useful potting space to grow your vegetables. Made from quality materials, this greenhouse will look great and stand up to the test of time. This garden building benefits from internal potting shelves, great for growing a range of vegetables and flowers all year round. There is a moveable shelf for extra flexibility. Heavy-duty tongue and groove boards are used to construct this greenhouse and the interlocking nature of this construction method creates a strong, hard-wearing and premium looking finish.

To ensure this building is long-lasting, it’s completed with thick wooden framing to support the boards internally. The UV resistant styrene glazing is designed to allow maximum light to flood the space whilst remaining a safer alternative to traditional glass. No floor is supplied with this greenhouse, to ensure water can drain easily after you have watered your produce. All 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.

The Mercia Traditional Tall Wall Greenhouse is made in the UK, the timber is sourced from sustainable forest. 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 – you will find all the care guidelines you need in the instructions provided.

Additional Details about Your Order

If you think that a Mercia Traditional Tall Wall 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 product 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/furnishings for display purposes only. These are not included with your purchase. 


ALL DELIVERIES ARE DELIVERED TO KERBSIDE OR DRIVEWAY. All of our Mercia products are delivered flat packed other than fence panels (which are delivered fully constructed), direct to your home, and are supplied with a set of instructions to support assembly.

Booking Delivery

You will be required to book your delivery date at the time of placing your order (except for Metal Shed). Our 'Request a Delivery Date' service is available to the majority of areas and you'll find that the majority of the UK postcodes are FREE but some areas may incur a delivery surcharge and some postcodes are not covered at all. Select a 'requested delivery date' by entering your postcode 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.

Prior to Delivery

On the morning of your delivery date, you'll be sent an update by text with an estimated 2-hour delivery slot (this update can only be provided where a mobile number has been supplied on the billing address section at the time of checkout) together with a link to the manufacturer delivery portal where you'll be able to track your order.

Please note: Mercia Metal 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 sheds is identified on the product for the metal shed. Lead times are on working days (Monday - Friday) excludes Bank Holidays. These estimated lead times are provided by the manufacturer. Some remote areas will take a little longer.

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 unsafe 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.


Orders with Assembly 

The lead time for our installation option is around 7 Weeks from the date of order. With the installation option, the majority of orders will have their delivery and installation on separate days; there will be a small number of orders which will have delivery and installation on the same day. You will be advised by the manufacturer's installation team which category your order falls into.

Depending on the installation option for your order, you will be contacted within the delivery timescale and given a date for either delivery/assembly on the same date or a separate date for delivery and assembly.


Please note: all imperial measurements are approximate, and the Mercia Greenhouses are made from metric measurements. We would recommend that the base is at least 50mm bigger in each direction.
