Anything less than higher density in more areas is a catastrophic future for all of us. Sprawl is driving climate change. Sprawl hurts environmental air quality. Sprawl hurts health with long commutes and a lack of walking and exercise.
Can they walk to visit friends, the local shops, park, school, library, etc? All of these things were much more important to me as a child than a big backyard.
I live in a 1800 ft^2 single family home on a 50x140 lot in a city. Our block is 50% single family, 50% 2-4 Family. We walk to school, library and grocery.
Because of the developer incentives, there is no incentive to build old neighborhoods like mine. 5-6 story sticks on bricks crappy apartments, or McMansions on cul de sacs rule the day.
When I looked at building a home, you can see why. It’s very difficult to build a 1700-2500 ft^2 home unless you go prefabricated, have cash, or can do the finish work yourself. The financing only works for real big or real small.
