Right now we are at 15 ft long by 8 ft wide. We have shelving on each side and one smaller row down the middle, enough to fit a 18" tray if we need to. I figured that we have so far spent roughly 15 dollars on it, some screws and caulk is all we have bought. Everything else is from old buildings, so very cost efficient. It is kind of an eye sore though, not to much time has gone into looks :) .
