Hi, I have a 85 foot by 24 foot polytunnel, 2 years old, from First Tunnels. Plastic's a bit ripped but the frame is perfect. It's not concreted in, but the base plates are dug quite deep so it would take a certain amount of elbow grease to get out.
I no longer need this tunnel because I'm relocating. And, rather than try to sell it, I'd rather just give it away since the plastic probably needs replacing (about 75 per cent is fine).
The tunnel is in Kent. Do email me on [email protected] if you're interested.
