Here in Munich, they indeed are... and wherever possible, they and their often beautiful gardens get torn down, and the entire plot gets "densified" by creating as much indoor space as possible. What was one house for one family is now at least 6-8 apartments for DINKs, often built in shoddy quality with corners cut everywhere but priced and sold at record amounts (that still get paid because all the tech and car bros massively distort the wage market).
On one side, it's positive because the lack of housing is absurd.
On the other side, none of the surrounding infrastructure was built with that density in mind. Parking overflows everywhere because you physically (slope angle vs lot size) can't create enough garage spaces, traffic itself is getting more and more dangerous as the small streets have been built as tiny veins but now have to carry 2-3x the traffic load, public transport can't handle it as well, doctors/kindergartens/schools are on the verge of collapse, the grid operator doesn't allow PV or EV installation because all the density increase would first require a complete overhaul of the last mile distribution grid. And on top of that, biodiversity has taken a visible hit as all the trees and bushes getting ripped out and replaced by steel eyesores and yards being replaced by gravel so that the hipsters don't have to bother with mowing a lawn don't support insect life, so the birds vanish as well. No free-roaming cats any more either thanks to traffic.
Seriously, screw urbanization and gentrification. We absolutely need to revitalize rural areas again.
