How are you going to orient the building 30' wide x 40' deep or 40' wide and 30' deep?
Work bays need to be about 15' wide and 25' long with work bench and toolboxes outside that area. Storage/parking bays can be smaller 10' wide x 20' long.
Also don't cut corners on garage door sizes...make them over sized if possible. My new 3/4 ton pickup won't go through my house garage door that's 9' wide without folding the outside mirrors first...I wish they were 10' wide doors.
