I own a row home in an urban area in which on street parking is a nightmare. We have a small (20' wide x 25' long) backyard that abuts an alley. Both sides are hemmed in by tall fences. I am thinking about converting some/all of it to a driveway/parking pad. Ideally, we would have enough parking for 2 cars (tandem would be okay), but I do not think it is big enough.
How big does a driveway need to be if you are pulling straight in/out of it?
What about if we did some sort of parallel parking spot for a single car?
