Our builder put up a 48'x48' barn for $14K and he placed the stone inside and leveled, hired the crane, poured the post pads. The Amish quotes were around $12K but they wanted me to hire the crane and pour the post pads so it all worked out about the same cost. I have a ton of wood left over from the Menards kit. I don't know who screwed up but I think they gave me way too much lumber. I have enough to build my room after I pour half a slab. My present barn (40x64) has the whole floor heated with a Taki on demand water heater and it works great. My plan on this barn is to do the same only three zones and build a small room like yours that's finished off with steel.

Were doing the same thing, bought a Menards barn kit, hired a local guy to put it up since we're 3 hours away. It took me all summer to clear an acre of woods, haul dirt and level the pad (very hilly here). Don't forget all of the stone for the drive and the barn pad. I have about 10K in stone for a 500' drive and the pad. Stone is about $30 / ton delivered. Concrete is now $200 a yard, and I don't think I'm going to pour this year. The money will add up fast with all the other things you might forget about. If things go sideways soon, well live in the barn, other wise building a small house in a few years.

I have an AC1 (which is a little larger, 4.0 HP) that runs great. Thinking of coupling it to an ST gen head for backup power. Trying to find a starter at a decent price, new one are as much as I paid for the whole engine.
