The aluminium and galvanised steel components require no treatment, and the polycarbonate panels won’t discolour or fade in sunlight. Backed by a reassuring 5-year limited warranty, you can invest in your greenhouse with confidence.

Two manually opened roof vents allow you to regulate the temperature inside the greenhouse, preventing overheating during warmer months and maintaining optimal growing conditions. The integral guttering system provides a sustainable water supply for your garden.

Assembly is straightforward thanks to pre-cut polycarbonate panels with uniform profiles that simply slide into place. No specialist tools or experience is required. Please note that this greenhouse is designed without a floor and should be fixed to a firm, level base.
