I'm sure of the concrete footing, not a slab, cannot afford that. They can go on gravel, but I want something more permanent and solid. I mean, it's not just a carport or for storage but to house animals. And definitely cannot afford another $5-10K over the cost of the building. I'm sure I can find someone local to do the footings so will have to get some estimates. The guy doing our pasture could do it but he seems to have too many irons in the fire and is leaving for Cuba in November anyway, no idea for how long (Nat'l Guard).
I'm not doing runs, per se, hard to explain, no pop doors cut. May rethink that one but for now, that's the plan. They'll go into the center aisle, with double doors closed, to get out of the pens on nasty days or free range one group at a time, which is pretty much what they do now, except each has a pen attached to their coop.
Thinking rectangle building about 28 or 30' x 25', double doors on center of one end that open into the center aisle, 4 windows, installed barn fan to exhaust heat, 10-12' height. I don't want it for just a coop but for storage, too. The building itself, depending on who does it and options, etc, has been estimated by a couple of these companies at between $9-10K, but that isn't with insulating the roof so it doesn't sweat, an issue with this type of building and having animals in there.
Of course, I may completely do a 180* and go back to planning a wood building but I hate the thought of paint again. Maybe a stained one would be less work. But, unless you get one custom built, they only come in 14' widths and are more expensive than the metal ones, comparing floor space.
idk if uhve amish near you butg the amish build great barns and buildings
