Finished building a shop/studio/MIL apt 1600 sq ft building for son.
Not including own labor, Total cost (less permits) about $5 per sq ft! OF the total, $1k was oak flooring, $1K for mini split, about $1.5K for concrete and rebar, $1.2K for roofing, and $1.1K for insulation. < $1K for plumbing and electrical.
Most everything else salvage/surplus/craigslist free stuff.
Will post more as interest evolves if there is any. DO not recall how many photos can be attached prior to filling allocations?
