i just built my shop this last year. everybody thought i was crazy for not putting any windows in. both doors face the house. i have a new lock for the drive through door and i can also put a extra bar on the rails then go out thru the walk thru door.
the whole garage is behind a privacy fence that has the drive though gates locked. the mote is will have to wait till the end of the year with the insulation. i also put in just as many 22 outlets as 110. i also built it just as big as the city would allow. i also built lots of storage, shelves around the upper couple of feet of the wall, and lots of free standing storage. over build and over enjoy is so true!
