The drawback I see would be the same as for polytunnels, depending on the quality of the plastic used, that it would need to replaced every few years. Also, I would be concerned about wind damage on a vertical surface, at least with a curved polytunnel the wind can be deflected around it. Finally, the use of nails will obviously introduce holes from which tears will start. The sheeting is 4 or 5 euro a sq. metre, glass does indeed cost maybe 7 or 8 times that, it is a trade off.

No problem. If you are serious about having a long term greenhouse then you should buy one for the reasons i mentioned above. A friend of mine got a polycarbonate one lately from STEELTECH. He is delighted with it. Cost was 1500 though supplied and erected. There are any number of similar companies around. An alternative is to get a second hand one, you might get lucky. I got one quite by chance for 50. 8 ' * 12' aluminium.

I Made a Dome Greenhouse last year and covered it with Polytunnel Plastic, the sides are not totally vertical but it stood up to all the storms over the winter and spring,
the Polythene is holding up well and traps the heat well

I just looked back on that thread TMAK, can you show me a close up of the centre hub, did you make or buy them?

Hi Tagwex. I don't know why but I only saw this comment now. I made the centre pieces. ''Twas easier than cutting compound angles. I'll take a pic when I'm out there later on

When I lived in Dublin I erected a "Conservatory" onto the back of the House... being short of cash I approached my local Window Installer who was always anxious to dispose of old Aluminium Windows he'd replaced...after a short while I had sufficient Frames to complete the Job...

12 years on and that "Conservatory" is still standing and being used on a daily basis...just thought it worth a mention if you really want a DIY project that wont cost the Earth and will be unique in the sense that it will be one-of-a-kind and you can extend it whenever needed...

Ado -- I know I've mentioned this in other contexts but corrugated plastic would be my solution. 'Back home' in the UK we lived in the same house for 31 years before moving over here. I had a small wooden sided shed there that had a tin roof when we bought the place, but of course that made it terribly dark so I re-roofed it with clear plastic to let more light in.

When we left, I'd re-done it once after about 20 years and the second lot was showing no signs whatsoever of needing attention. With a simple wooden frame, galvanised screws and plastic washers it's easy to drill and fix PLUS, if you're worried about the risks of ultra-high winds, it's easily covered by overlapping sheets for added strength as you see fit. It comes in a variety of lengths which, for a hopeless craftsman like me, would make me ensure my timber frame matched standard sheet sizes to save cutting.
