The cost will depend on where you are located and the building codes in your area. If you are not required to do things like sheetrock the inside or use fire rated materials, you can save a lot of money.

x 2 on construction workers being short on work but the cost of materials has gone up many times in the last few years. The cost of copper for the electrical and the cost of shingles for the roof has doubled in the last couple of years.

For a 6 inch concrete slab, wood frame, sheetrock interior, electrical ( 400 amp ), two roll/raise doors, one pedestrian door and a shingle roof.....budget $20k to start.
