id suggest an "office area"; some where to keep clean, keep your notes and research, internet access, a table for drawing out visions or ideas; that kind of stuff. ill admit that i love a good coat of grease and sweat, but after or before when im gearing up for the next thing its nice to have my own place where im in charge, a buddy of mine built a loft so that he could look out over his shop from the office. also i love the foxhole stations (the one where you drive over the hole)they dont seem to be so common any more, and truth be told ive only seen one in a residential, but it helps if your doing something that you have to be under the car and need some help from above at the same time. peg board is pretty good for keeping handtools, and you cant forget the tunes and beer! and always keep a good collection of ZZ top, Sammy Hagar, Kiss, Johny Cash, and the beach boys. but remember you have neighbors, so make sure your system can go loud enough for them to hear it clearly! lol
