Great thread! I'm currently working out of a 7X14, but have no shop, so everything goes in it. It is getting way too small to be efficient with (too much digging). Part of the problem is that I got it from my previous employer when I started my business. He had just put in some shelving units from Costco, and they don't fit some tools very well. Gonna do some remodeling this weekend. I'm planning on getting an 8.5X20 sometime this year. (Planning on an Rv toilet and sink and a propane furnace from an RV as well).
Out of all the set ups in this thread, Mitchell's somewhere around page 2 or 3 is the one that looks closest to what I have in mind.
Thanks for all the good ideas. I'll be sharing what I do once I get things finalized. Maybe some before and after pics too!
