I like Fint's suggestion to go to the left side for drive expansion.

Going to the right would mess up the aesthetics of your home, Don. Big time. Just wouldn't look "right". Using pavers wouldn't change that except it'd be easier to remove, should the occasion arise.

If you add to the left and you have a gate to the back on that side it allows you to move your vehicles from front to back as needed.

Using pavers instead of concrete to the left would be even better!
