So the shop that I built my house in had a door that wasnt tall enough to fit the house with the roof installed. So I built the house as I normally would and did as much as I could minus the roof. When the time came to pull the house out and set it up outside we already had the roof joists cut to length and all the bird mouth notches cut into the joists. Getting the house out still proved problematic, I had to drain the tires down to 5 psi just to get enough room to get it out. I also had to get a 5" drop hitch and flip it upside down to clear the garage door. The house cleared by millimeters, not going to lie it was a little scary!
