Made in the UK, using ethically sourced FSC certified timber, the 8 x 4 Evesham Lean-to Greenhouse from Mercia is a space-saving design that simply attaches to the side of a permanent wall. This greenhouse is great for smaller or more urban gardens looking for somewhere to grow a range of plants and flowers throughout the year, and costs are kept low by taking advantage of an existing wall in your garden. With its robust shiplap cladding and timber frame, a lean-to greenhouse is sure to become a prized feature in any garden for years to come.


The lower walls of the Evesham Lean-to Greenhouse are constructed using premium horizontal interlocking tongue and groove boards with a shiplap profile. The shiplap profile includes a protective and aesthetically pleasing lip to create a strong, weather resistant panel. Complete with thick wooden framing to support the cladding internally, this building offers a rigid and long-lasting structure. An opening roof vent allows for ventilation during the hotter months, and the extensive glazing provides ample sunlight for plants inside. Depending on where you would like to position the Evesham Lean-To the door can be located on either of the 4th sides.

The glazing is made from UV resistant styrene, which allows maximum light into the greenhouse while being safe and shatterproof. No floor is supplied with the greenhouse to ensure water can drain easily after you have watered any produce or plants you are growing inside. 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. Alternatively, sit back, relax, and have our professionals take care of building your greenhouse by adding assembly to your order.   

This building comes with an anti-rot guarantee. To ensure your garden building looks great and lasts, your greenhouse 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 Information

If you think that the Evesham Lean-to 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 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 this greenhouse decorated with accessories/furnishings. This is for display purposes only. Your order will not be delivered with any of the accessories/furnishings shown.

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 12 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.
