Anyone want to take a WAG on cost, or have a cost estimation website?

Garage option: 12' x 21' footprint, probably have to stay within that footprint or close to it, tear down structure and build new two story structure, (very) small studio on top, workshop/studio on bottom, exterior staircase, little balcony, wood frame with wood siding and composition roof.

Basement option: take about 40-50% of the 1000 sq ft basement, 8' 6" headroom, slab floor and concrete walls, one big egress window in window well, one glass exterior door in an entry well, would need to cut a 30' trench in slab for drain line to reach stack.

Yeah, neither sounds like a great place to live, but that's all I have room for.
