We bought this polytunnel along with another from Northern Tunnels for a project. We put one up and haven't ever had the need or time to put the other one up and it has lay unused for a couple years now. It's 48ft (14.63m) long and 30ft (9.14m) wide high sided version. It cost new £7,5000. Some of the timber isn't in great condition, easy enough to replace. The first picture is from the website where we bought it from. The last is of tunnel we have up. Please get in touch if any questions.
