I've been using a converted garage space as my studio / man cave for a while now. Up until now it was pretty much just a garage with a bunch of crap in it. It worked but it was just shy of feeling like an actual living space.
I've been meaning to remodel it and make it much more comfortable and less cluttered for quite a while. I finally bit the bullet and tore everything out of it so I could remodel it over the long weekend.
The walls were / are in pretty rough shape. It is a garage after all, so I didn't even spend much time filling holes. The walls got a couple of coats of paint. I used peel and stick tile (faux wood) on the floor, full width of the garage and about 12 feet deep. There is a window that I stuffed with insulation and blocked off completely.
Man am I stoked. It turned out incredible. I'm really no good when it comes to colors and design kind of stuff, but I really could not be happier with the way it turned out.
One side is my workbenches and stuff, the middle has a couch and tv/stereo, then the other end is all devoted to instruments.
