FTFY:
I built a hutch with 4 individual compartments, each with their own door. The compartments are 3x3x0.9 meters and the floor is 0.9 meters off the ground. So the whole thing is 1.8 meters tall, 3.7 meters long and 0.9 meters wide.
Floors are 1/2 inch hardware cloth, the sides and dividers are chicken wire, and the roof is corrugated metal. The whole thing was built out of 2x4s and the doors were framed out of 2x2s and attached with hinges and clasps.
It works well for me. Only issue I had was poorly secured chicken wire dividers that the bunnies could pull lose and slip through. I reinforced them with 2x2 frames and stronger Staples. Haven't had issues since.
