I am very thankful for my shop. We built it a few years ago (long before I thought about building an airplane). Last year we finished out the inside, insulated, and have heat and air conditioning. The building is 52' wide x 60' long with an 18' ceiling in the middle. I have a lot of stuff in there, but definitely have room for a fully assembled RV-12 with plenty of room to spare. I just wish it was connected to an airport!
