I think these alley house design are OK if the people who live there are the typical 2 kids and a dog type and the kids are not at the driving age. Imagine what happens if the family is larger and all the kids drives. Where would you park your 4-6 cars? At least with these “snout houses”, there’s drive ways you can park 2 more cars in to keep the street clear. If you don’t have drive ways, the streets will be full of cars and visitor won’t have anywhere to park. That’s one of the reason why I hate alley homes. They’re just big giant condos to me.
