This is a wonderful idea for those who need multiple "apartments" for small groups of birds. It's a great way to handle selective breeding pairs. Although the builder has designed it for trios of tiny Seramas, the modular design is easily adaptable for slightly larger birds, like bantams or Silkies. The two-level design keeps food and water clean while still allowing easy access for coop maintenance. I especially like the fact that the entire structure is raised to table height - a real plus for anyone with back issues.
Since the entire coop set-up is in a larger building, there is plenty of ranging room, as well, but the outdoor "play room" is the best. It's even got its own vacation accommodations! Not everyone has access to a wonderful tree stump to build around, but it would be easy to make-do with a built structure ... just not as creative and cool!
The note about heavy doors is well-made, as that would be an issue. Reinforcement would definitely help. This coop could also be modified to work outdoors, simply by using hardware wire instead of plastic netting and making the top half of the door (across the feeding level) solid wood, as protection against the weather.
All in all, this is a very well thought out, nicely designed set-up.
