8' x 4' Lean-To Greenhouse - Silver Aluminium Frame & Clear Polycarbonate Panels
Maybe you’ve always dreamed of having a greenhouse but didn’t think you had the space to make it happen. All you need is a small outdoor space, patio, or balcony and the Palram – Canopia Lean-to Grow.
This small greenhouse offers the advantages of a larger greenhouse in a smaller footprint and with the additional advantage of retaining more heat. The wall that the greenhouse is built against radiates heats back into the greenhouse. It also means you have quick access to electricity and water and look beautiful as part of your home.
The Lean-to Grow utilizes two types of virtually unbreakable polycarbonate glazing, twin-wall roof panels, and crystal-clear wall panels, for protection from overhead sunlight with plenty of exposure to grow your garden.
This small greenhouse also features a sturdy, corrosion-resistant aluminium frame, an adjustable roof vent to control the temperature and moisture levels, a built-in gutter, a lockable door that can be put on either side for extra protection, and a galvanized steel base for additional stability.
Bring your planting dreams to life no matter the size of your space with a Lean-to Grow greenhouse.
- Highly resistant, transparent, and safe polycarbonate DIY greenhouse (with Fine Shield Technology™)

Frequently Asked Questions
1. Do your products come with a warranty?
Yes, all Gradwell Group products come with a manufacturer’s warranty for your peace of mind. Warranty periods vary depending on the product type, but most of our aluminium and GRP ranges offer 10–25 years of coverage against structural defects, corrosion, or weathering.
2. Can you deliver anywhere in the UK?
Absolutely. We offer UK-wide delivery on all products, including large or heavy items such as carports, patio covers, and conservatories. Delivery times may vary based on location and product availability, but we’ll always keep you updated every step of the way.
3. Do I need planning permission for your products?
In most cases, our products do not require planning permission—especially for carports, door canopies, patio covers, and roofline items. However, we always recommend checking with your local planning authority for large installations or if you live in a conservation area or listed building. Our team can provide specifications to assist with your application if needed.
4. Can I install the product myself or do I need a professional?
For larger structures like aluminium carports or lean-to conservatories, we recommend using a qualified installer for best results. We can also arrange professional installation services through our trusted partners.
