My hubby (aka Batman) built this with no plans...just the basic info I shared with him. Then he drew out a rough idea. Our total cost turned out to be in the neighborhood of $200.
There is a large slide-out tray for the bottom. I'm planning to use the deep litter method. And I think this will be adequate. Time will tell.
That top roost bar has since been moved because it was in a silly location that made it unuseable.
Here's a shot of the inside
The run is 12 feet long, I believe. I do wish he had put in a door in the center of the run instead of just on the end. He can add it later.
