I only need a wash stall occationally, so I'm making that a part of one aisle end. That way I can get away with a 36x36 - which includes one 12x8 feed, one 12x12 tack, one 12x16 foaling, and three 12x12's with a foaling partition in between two. It's the excavation that going to be a big part of the equation - and I don't have an answer. I'm considering hi-tensile polymer bands on halfrounds with one top safe fence electric braid. You may have to do your ring in stages.
Footing is an enormous cost.
I'm having a terrible time just making the decision to build a clear span barn, or post and beam. Once I make that decision, I can weed out a lot of stall components. All rights reserved.
