I built a 30x30 and its alot better than nothing(I couldnt fit much bigger in my back yard) but build it as big as you can - you will never have too much space. I opted out of the bathroom due to expense of the plumbing and house is 5 feet away. of course you want a lift in it and you'll need room around that, IMO the lift was the best money spent- Priceless!
