The 8x4 Access Aluminium Large Coldframe is a great way to extend the growing season and protect your plants from harsh weather conditions. Perfect for use all year round, the Cold Frame can be placed directly onto the soil or on a raised base, providing shelter from strong winds and harsh weather conditions. In the spring, when temperatures start to rise, the Cold Frame can also be used to house tender young plants, acting as an intermediary stage between the warm conditions of a greenhouse and the cooler environment of a garden.

This Large Access 8x4 Coldframe is made from aluminium, with a 25 year framework guarantee. It is glazed with 3mm toughened safety glass, and has sliding side and top panels for easy access. A full range of options are available below including Shelving, Louvre and Misting Kit.

2x3 Access Harlow Mini Lean To Greenhouse Toughened Glass
Nice little potting shed/greenhouse just what I wanted. Slightly disappointed with the size of the two shelves - think they could have been a bit wider to accommodate plant trays a bit more safely. Need to save up for the back glass as I feel it might need it in the winter and give it a bit more stability. Very helpful company to deal with as we had to put the delivery date back a couple of weeks due to my husband having an operation.

1x3 Access Westminster Lean To Greenhouse Toughened Glass
I needed a very small greenhouse, but wanted a proper one. This is absolutely perfect. I can cram loads of seeds and seedlings in, then temporarily remove shelves as they grow bigger. I am absolutely delighted. The company were very helpful too. It was slightly trickier than a one man job to assemble, but pretty quick and straightforward to do. I’d definitely buy again.
