Want a budget greenhouse?

Doubt it would stand up to much wind to be honest, very cheap though.

Funny you should say that, tanith. One of our neighbours has just built one, almost identical. The last 2 days we've had very strong winds and one side of the plastic cover was unearthed flapping about. What a noise.
I noticed today he's somehow managed to fix it, but already one corner has come loose again. He works for a market gardener, and wants to start up on his own.

Netting over the house would hold it down? You have to start somewhere and I have been looking at polytunnels as a substitute for my greenhouse which is getting senile....

There are three more links on the site!

I would think if it was a small one, and you put it in a sheltered spot, it would be fine. Also be careful about which way it's facing. You don't want the prevailing wind blowing in the front door.
This one of our neighbour's is huge, bigger than the one in your link. And on an exposed plot.
I was surprised he put it there, he Hasn't been here long and maybe hasn't realised how severe the weather can be.

Hope he learns by experience!
