I am wanting to move out of my garage and into a shop. I am thinking about either a 24' x 24' or a 24' x 30 depending on permits and cost. I have a very level lot but I will need the basic grading. It will need to have two garage doors on the front of it so it could be used as a garage if I sale the house. My question is just how much would I be looking at for the building with a shingle roof, vinyl siding and garage doors? I don't want any windows so that should help with the cost. Thanks for any help.
