The biggest problem with the rear garage w/ alley access is the lack of driveway space. Aesthetics aside, one of the reasons I created this thread is because there seems to be a large majority of people who don't park their cars in their garage. Many use them for storage (or other activities) so that forces them to park on their driveway.
If they don't have a driveway, they will park in front of their home. In a front garage/driveway setup, there is still room to park at least one guest car in front of the house even if both cars are on the driveway (and you can park in front of the driveway depending on your HOA). In an alley-access garage setup, if both cars were parked in front of the house, there would be no guest parking and it would be more crowded which is what I've seen in Woodbury also.
Aesthetics wise for the house, no garage may be preferable, but then you mess with the street aesthetics and space.
