Balance 8' x 12' Greenhouse - Grey Aluminium Frame & Hybrid Polycarbonate Panels
When we tell you that the Palram – Canopia Balance Greenhouse Kits provide your plants with the optimal conditions for nurture and growth, we mean it.
With two types of glazing, you get a balanced DIY greenhouse that combines the protection of the diffused twin-wall roof panels with the light transmission of the crystal-clear wall panels for ideal growing conditions. All panels are made of UV-protected polycarbonate, a glass-like, virtually unbreakable high-end polymer that is uniquely suited for greenhouses.
The extra-large workspace gives you plenty of room to grow an abundance of vegetables and herbs and store the tools and accessories you need. The Balance Greenhouse is also extremely accessible with wide double doors and a low threshold for wheelbarrows to go in and out and enough room to transfer large trays of plants.
The combination of the safe polycarbonate panels with the rust-resistant, aluminum frame and extra strong support beams provides you with a greenhouse that is well-designed and durable, so you never have to worry about the sturdiness or safety of your greenhouse.
For a beautiful, well-designed, and spacious addition to your gardening experience, get a Balance backyard Greenhouse today!

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.
