I do not mean to offend but you asked : the hutch looks as it can be knocked over to easily: any wood bunny can get to it will eat; the floor looks to be to small a gauge wire;there is no roof for sun or rain; can not tell if building is refecting sun on cage or not,if it is you might have roasted bunny; if the blue foam is where bunny can get to it,it will be chewed; the wood is not exterior rated so weather will destroy it; the wood around the animal will collect urine,also needs a better system to secure top,there is a lot of information on the web on building hutches,might want to check them out,looks as you put a lot of work in the cage and cute looking rabbit.Lol.
