This cage should only be used as a base; it is far too small for rabbits to be kept in, even temporarily/overnight. The Rabbit Welfare Association (RWAF) recommend permanent access to a minimum area of 48 square foot. This is 3.5 square foot.
This rabbit hutch is excellent. It was very easy to assemble and seems very sturdy. I have also got the hutch cover to go with it which fits very snugly and is is easy to access the hutch. I would recommend that you keep it out of the wind as its very light and would probably blow over.
