I wish I'd seen the Nellabrooder plans before I went and tried it on my own. I built one with three levels. The lights are on dimmer switches you can see stuck on the side. Each level is a different size because I eyeballed it. I would have loved to take better pictures, but I couldn't get far enough back. My back is up against my garage door as it is. The front used to be entirely hardware cloth until I got tired of sweeping up shavings. I had to use the good stuff because snakes have been known to wiggle into my garage
. I stuck a piece of linoleum behind the bottom piece of hardware cloth to try to keep the mess contained. Now that I've switched to brooding on pellets, I'm REALLY glad I added that lip.
The main advantage I see in the Nella design is the fact that it can be MOVED. Mine is so heavy that even when I'm working with DH, it's a beast.
