We live in a particularly windy corner of east coast Scotland. We have a Billy-oh greenhouse (because I wanted a wooden one, but didn't have much money). It was crap right from the start, and is about to blow away completely - may have left the garden by the time I get home from work.
Any suggestions? Am happy to go for aluminium, and budget is £500max. Also if they do a build-it-for-you service, so much the better.
