If you look back at many of the threads about coops, the majority offer a far too small protected area and a small run, they also are made of soft wood which will be easily chewed and destroyed. Many are difficult to access as the doors are very small.
If you are going to become a rescue you need strong hutches which will last, rabbits do seem to chew more if they can see and smell other rabbits. They need to be big enough to use for different rabbit needs with elderly or very young rabbits otherwise they will be confinded to tiny bedrooms which are totally unsuitable.
