Need some input once again from you seasoned guys here- I'm about to amend a pole barn contract, and the cost to increase the 4in fiber concrete floor to 5in is $1556. To increase the 12ft wall height to 14ft is roughly $2K. This is for a 30x50, and now is the time to make up my mind:laughing: I would like the future option of both a 2 post lift, and a mezzanine, but a $3,500 savings by staying at 4in crete and 12ft wall height is enticing as well. Thoughts??
