The plan is 40x60 pole building with a 6" heated concrete floor. All but one 12x12 corner where my office will be. Planning a huge build at the entrance also.... The shape of the largest tank for the pacu and large cat rescues will be an odd shape. I plan to have multiple "ponds" set up along with many tanks, mostly to get them out of the house. The construction of the pole building will be completely moisture proof and insulated to the gills (pun intended) Eventually (years away probably) I'd like to open the rescue to the public...
