Don't make the place to nice or she will get suspicious. My wife once asked why I spend so much time in the shop with my racecar and I told her it doesn't nag or complain and it does what I tell it to. Then she said "well she spends more than I do". Not sure who won that one.It's a great place to stay when your wife kicks you out over the car.
Jason, check out this thread:http://www.yellowbullet.com/forum/showthread.php?t=151650 there were some pics of loft/offices in there if I remember correctly. If you can wait long enough (LOL), we are building a 4000sq ft building that will be done with a loft/office. I put lol because we haven't started breaking ground yet. But thats just around the corner. Hope it helps.
