I'm planning on doing something similar Did they pour the slab first and then form the curb /perimeter wall and do a second pour? On my current garage I have two standard doors and I find it convenient especially in bad weather If I want to fire up one of the cars the other one is not getting rained on and losing all the heat. I can open one door halfway and back up the Duster to let the exhaust out but still keep some of the heat in and once the car warms up it will heat the garage for a few hours.
