Hi all,

I know the name suggests a Tunnel, but does it have to be? Here's my problem... I have three raised veggie beds in my garden already with footpaths around them. My lawn is split level and they lie in front of the flower bank, at right angles to it. At the top of the bank is my Garage wall. (With me so far?)

I'd like to build a structure from the garage wall, so that I can have the existing bank as well as the raised beds in the tunnel. I can do it quite easily using a timber framed design with three walls and an angled flat roof. (would look like a lean-to) but can I still use plastic for the sides and roof. Basically I'd use four separate sections of polythene. One for each side and the roof. Garage end won't need one.

My idea would be to use batons to secure the polythene in place and then nail these to the frame. My door would be positioned at the bottom of the bank so as I walk in the bank is on my left and the three beds are on my right. I never seen one before, but there's always a first. I could go for the standard tunnel but it seems and awful waste of a bank.

Any help, advice, admonishing remarks would be greatly appreicated.
