My opinion of the ideal barn, for what that is worth, is that the best use of available space, being cost effective and has the most advantages is a center aisle barn, BAR NONE.
Everything else are compromises.
Shedrows don’t have any more airflow than a center aisle barn does.
All can be designed with all kinds of airflow and as closed up for those in the North or open for those in the far South as anyone wishes.
The principle of any structure is to be out of the weather and center aisle barns provide you with the most protection for the least money and materials in a barn.
Shedrow barns you need to frame extra for that front support of the roof and if you want enclosed from the elements, do like we had to, put tarps up and let them down to keep rain and snow from getting in there.
Here is the 22 stall shedrow barn we trained race horses from:

If those two sides had been built butting each other, they would have saved framing posts, there would have been a 16’ aisle in that middle and we would not have needed tarps to keep water and snow from getting up to the stall doors and could have been snug as a bug inside that aisle in the bad weather.
If building today, I would seriously reconsider any other than center aisle, no matter how big or small a barn we want.
We have all the great outdoors to be out anyway, why bring the outdoors into the barns?:rolleyes:
That defeats the purpose of structures to give us and our horses protection.
