** The THUMBS DOWN Hillary supporters are cracking me up*** I built this two story 12×24 barn with a 8×12 bump out by myself in my spare time over the last year or so. DO NOT buy a kit or hire it out, you CAN do it yourself. It is NOT as hard as you might think. I had NO PLANS and no help, i just had an idea in my head how i wanted it to look and just went for it. I just started with a 12×24 SQUARED foundation and just went from there. I made decisions as they were presented to me and it all worded out.
