This is a single story modern garage plan with 3 bays is built on a slab foundation.It gives you 1,041 square feet of parking space inside.The roof has a low profile 2:12 pitch. since the ceiling is sloped it goes from an approx. 8' in the rear and 12' to the front. The trusses are top cord bearing so they hang down into the garage off of the walls.Without raising the walls you would not get much height for a lift in there.
