1. I have a Rubbermaid Big Max shed that I use for other things. Be aware that when I first installed it, it was hot. The shed outgassed enormously. It smelled SO bad that I couldn't stand it. I would not close animals up inside it with it smelling like that. Now that the weather is cold, it is fine. I look forward to next summer so that I can see if the outgassing has gone away.
2. Some people down the road have taken a plastic small shed that looks almost like a locker but short, and connected it up to a dog run (chain link). They move the whole thing around their yard. I think it's great but watch out for a hot shed in summer!!!
3. I have a metal shed that I use for one of my coops, and I love it. It is my favorite coop. It gets hot in summer but is cooled down enough by nightfall that it's ok. And it doesn't outgas.
4. Be aware that to put together my Big Max shed, the two skilled men doing it were complaining about how HORRIBLE it was, and forbade me to ever buy another plastic shed again. The roof especially- it took 3 people holding it at various angles to get it to stay long enough to get the screws in.
5. The ground under it must be completely level. And I'm not kidding. You can barely get it screwed together with a perfectly level surface. If there is anything crooked, it won't screw together. We used a tractor and 4 people to dig it out. Then plywood and concrete blocks for the foundation.
