Well I have been working on this for almost two years. I have done all of it myself, with the help of some family and friends. It is a 30'x50', with three 10x8 insulated doors, and the ceiling is just over 10'. I built it to park my wife's car and my truck in, and still have a bay to "play" in. It will have a bathroom with shower and radiant heat in the floors. I do automotive upholstery work on the side and do auto body work for a living. It isn't complete yet but I finally got power hooked up about 3 weeks ago, so I just now got around to doing any kind of build thread or progress thread.
Sorry for the long post, but it's basically start to finish. Well almost, still have a few things to do yet.
So here are some pics:
Here we are pouring the floor, unfortunately this is the first pic I have of the progress.
Time for the power trowel!
Floor cured, and time for some walls
Sheathing going up
Here's the supervisor, making sure we are doing it correct.
