Tomato greenhouse

I saw one of these once full of tomato plants, used as a greenhouse. I'd love one in my garden but even if I could afford to buy one how would I get it home? They're not known for being lightweight and apart from a truck I imagine you'd have to hire a crane to lift it. Then once you get it to your garden do you have an area of firm enough ground to support it or does it sink into the earth underneath.

Too many problems so don't think I'll bother!

Can you see what looks like a cat looking out through one of the windows?
