Building a garage, cost $$$$

those are some nice garages guys. I miss my old garage, 26x30x11 standered garage cost $18k about 8 yrs ago. The only thing I did was the insulation, had a pellet stove to heat it and window ac to cool it.
My new house the garages are attached with a supporting wall down the center. I think they are 15x24 but 1 has 15' cieling for future lift and i will be losing the other to make a play room for the kids and a pool table when they are a little bigger. I'm saving now for a new garage.
