Giving a cost for your area is difficult as each part of the country, the rates for labor and material differ greatly. For example, 4 years ago, I had a shop built with 9' 10" walls. The physical dimensions were 30 x 54. 24 feet of the 52 were 12 foot wings on dirt floor on each side with the exception of one side had a 10x12 concrete floor with 1/2 bath (commode and sink). The roof is galvalume steel, the concrete is 4" thick, the interior walls and ceiling is sealed with 3/8" plywood, 100 amp electric service with wall outlets not more than 10 feet to the nearest one any where in the shop. It is also insulated with 6" bat fiberglas in walls and ceiling. Lighting is from 6 of the 4 foot double bulb fluorescent lights plus interior and exterior double bulb flood lights. It has one 16' insulated garage door and one 10 foot insulated door and one 32" manway door plus one window in the bathroom. Exterior is 3/4" exterior grade T111 plywood and painted. Total cost was $25,500.
It is all wood structure except for the roof.
