Having read this the other day, it seems the lots for them are smaller so it’s still better than typical suburban sprawl, but yeah not by very much. It’s like duplexes, just without the shared walls.
At the same time, I totally understand the logic of the buyers. Condos and apartments really aren’t the same as having your own property that nobody really has say over but you. You can’t make big changes to a condo without approval of the building owner or whatever even though you “own it”, you share walls, and have no yard.
It’s just one more piece to the puzzle, it’s not meant to be -the-solution, just one of many.
