The side walls are going to be tongue and groove pine like the ceiling in the barn and my small shop. Those walls will hang neon signs and such. The back wall and wall around the mezzanine will be drywall and painted. Black steel railings up the stairs and across the top.
Of course, Pizza oven and five beer taps on the hand made mahogany bar with Hemi engine blocks as stools.
Ok, maybe not all that, but it’ll be a “museum” like shop that is really meant to stay clean for reassembly after paint. No fabrication and no dirty work!
Cheers
