You can certainly turn your car stalls into garages. You might have little time and some basic tools to accomplish this conversion. But, keep in mind that a car stall is already a garage minus the walls, with no openings or windows. This means it’s very easy to convert them into the garage. So, when you erect the walls and affix them onto the carports, they then become full-fledged garages. And the best part, you can do all this without a foundation.
