What a poor use of land and space for housing. Why not increase density with at a minimum a duplex or triplex? This is ridiculous.

A lot of people don’t want to share walls.

“Hey uh, I have 3 loud kids and a wife who is loud during sex. Wanna be my neighbor?”

Then maybe develop the concept of a brick wall and social skills.

These types of houses won’t protect you from noise. You’re never more than 5m away from your neighbors and only separated by cardboard. You will hear them.

I’m currently living in an apartment building from 1910 or so, made from proper bricks. Hardly ever even notice that I have neighbors.

Yeah, it’s almost impossible to build with bricks in California. (Earthquakes)
