Does a U shaped driveway have to pass in front of the front door?

Our home is very long and the driveway is to the far right of the home. Our front door is on the opposite side of the house. I would like to add a u shaped driveway to our original driveway for our kids to park but don't want it to have to span the whole length of the house. I had thought we would come off the driveway behind the bushes and the just to the left of the right lamp post.

It's hard for me to tell exactly where the existing driveway is located. It appears to be a straight driveway at the back corner on the side of the house. I am concerned that putting a U-Shaped driveway on the side of the house, may be a lot of paving that doesn't positively impact the street view of your house. The sidewalks are already forming a U-shape in the front yard. You didn't mention wanting to change the sidewalks, but wanted your current driveway to work better. Can you put a parking area behind the shrubbery, so the shrubbery could screen the appearance of the parked cars? This way you have parking, but don't bring the driveway through to the street making a "U". With this design you have to be sure that cars can easily back out of the parking space when they exit.
Thanks so much for submitting your question. I hope it helps! Nancy
