Cost for building a 1-car or 2-car attached garage

[Satish Nallapaneni]

How much does it cost to build either a 1-car or 2-car attached garage to an existing home in the Farmington Hills area. This needs the slab and everything. If the driveway also needs to be added, how much extra are we looking at?

I am looking for the cheapest option here. Nothing fancy at all. shingles for roof, not many windows, unpainted interiors, etc.,

Thanks.
