My rabbitry is about 18'x19' and about 9' tall. We built the rabbitry under a lot of trees so that there will be plenty of shade to help with the heat during the summer months. We built the barn similar to pole barn construction. The bottom 3' of each side of the barn has a piece of metal sheeting. The rest 6' are covered with wire screen. We put canvas tarps (that are waxed/waterproof) on each side (two per side - 6'x10') both on the outside & on the inside of the barn. I can roll the tarps up & down depending on the weather to have adequate airflow. During the hot summer weather, we have an air conditioning unit that we run. It keeps the barn around 20 degrees cooler during and the day and gets it down to the mid 70's to high 60's at night. It's definitely been a life saver this summer!
First here are a few construction pictures of the framing and then the finished project!
This is our grooming table. It's an old antique desk that I found at an auction for only $7!
This cage system holds twenty-four 24"x24" cages. My cousin built it for me and he did a great job! It works great :).
