Try the big green shed altho theirs may not be tall or sturdy enough

I have made a few different types. What size/pattern are you interested in?

Hardware house house and Mitre 10 garden centres sell put together tubular pipe ones, in a dark greeny black. Around $40. They aren't terribly strong or tall.
Mitre 10 garden centres sell a timber one - still only about 1.4 metres tall. Looks nice, round $90.
Rocklyn roses have ordered me two 2 metre tall, cast iron green ones. They are around 60cm wide, circular, with a finial effect on the top. $199 each.
Handyman books often have patterns for timber ones to make yourself. I had a nice easy one somewhere in a garden mag, but have misplaced it. I could draw it, but don't think i could describe it here. It wasn't a pyramidal one, more straight up and down.

have made tripods for the climbers/ramblers using three 3m treated pine rails feet set in the bed 2 m apart, then wired together at the top.Have a series of these joined by old chains,which provides for the really vigorous ramblers ,like Wedding day.
