Another reference point for you.
We have a 30x60 pole barn on our property with steel siding. It was used as a huge run in, so one long side is open. Luckily it already has electric and water run to it.
The plan is to eventually renovate into a four stall barn, tack room, etc. I got a quote for just the metal to redo the roof, siding (including fully enclosing the side that’s open), gutters, new double sliding doors, eight windows, and four dutch doors - $46k. That didn’t include labor, cement, or any work inside the building at all. Just to get the metal to my house.
