However, the kitchen is tiny and has very little counter space. Like other plans on this list, this garage apartment is best suited for a single person.

From Behm Design comes this basic garage apartment plan that, while small, still manages to fit in two bedrooms and a sizable kitchen with lots of counter space. 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.

Footprint: Width: 24″
Depth: 24″
Living Area: 576 sq. ft.
