LOL. Um......okay I have no real plans. Make 4x4 square. That requires 4 boards that are 48" long and 8 boards that are 45" long.
Here is the frame before i added the sides....LOL...it was so darn useful, too.
Then take those good ol 4x4 pieces of plywood. Cut a nice window whereever you think it fits well. Your "hole" should be approx 20" wide and as tall as you want. Then you can staple a 24" wide piece of hardware cloth across it. Screwing the framing over it will screw the hardware cloth down.
Make 2 of these. Make a third and cut a "pop door" opening at the bottom....whatever size works best for you.
Clamp each of these walls to the sides of your 48" square. Screw on.
Okay, that's as far as I've gotten. LOL. The back is still empty....I plan on making it about halfway solid and half a full door. Will also frame the pop door and add sliders to have a guillotine type door on it. Not sure on roofing material yet. It will be a basic sloping roof. Highest in front, sloping to the back.
Here you can see the inside of what I have so far.
Super easy, not the sturdiest thing ever, but I don't plan to drop it off a cliff either. Once the roof is on and the back wall, it will be sturdier than needed!
eta: obviously it needs roosts, 2 nesting boxes and feeder and waterer hangers as well. Eventually!
