15. Modern 2-Bedroom Garage Apartment with Large Kitchen from Behm Design

One thing you’ll notice, though, is that the living room is rather small as the steps take up a lot of space. Yes, this is a basic garage apartment, but from what we’ve seen, it would be a great in-law suite while allowing you to keep two vehicles safe and sound inside. Since it’s also a basic square and relatively small, the cost to build this garage apartment should be economical.
