Just had to add my 2 cents, this looks like a fantastic setup, and those of you with the room are lucky! Hope I can build one like this some dayGreat posts Joseph.
This is the inside of the gray and white barn. It is 30 years old.....just repainted it so I took some pictures. The inside is 8 pens of 4 X 8 pens. They can be used for growing, mating or conditioning. I put this back door in with the idea of leaving it open on really hot days, but never used it in the 30 years. This building stays pretty cool.
