The single-family house is the dominant form of housing in today's villages and small towns. It obviously meets many of the typical housing needs of a person. The mega-rational slab, the technocrat's answer (for others), has now been tried often enough. Both in the West and in the East. If you want, you can definitely find great LPG blocks in the middle of nowhere in the East for testing. I rather believe that the current crisis forces the construction industry to become more innovative and cost-conscious in some way. Otherwise, it really will be game over at some point. But back to the topic – by now almost all threads about financing and new projects here have dried up. Also a sign..
Even with the slab, there were solid concepts that could easily be further developed today... and are lived the same way in Asia.
One would have to start developing "communities/societies." A housing project including school, kindergarten, leisure, and shops, etc.
And then leave this only to investors who are committed to the mission of this project.
If one wants to combat the shortage in metropolitan areas, this will probably only work that way.
