Um, the purpose of the design is to get away from the so-called snout houses, that is, houses where the garages take up 60% of the frontage of the house. The architects and planners are trying to encourage more “neighborly” neighborhoods, picket fences, sipping lemonade of the veranda, and such. They think if we park our cars behind our houses our neighbors will see more of us as we walk around to our front door.
Of course, our side-entry garages still have doorways leading directly into our kitchens, so now our neighbors won’t ever see us.
