> single-story buildings cities with multi-story apartments
How many single story buildings does Lisbon have? I don't remember seeing that many. And how many of those single stary buildings are not under UNESCO historical heritage protection laws and you are allowed to buldoze?
Lisbon is a large city, not everything is the historic "old" city center. You don't even need to demolish anything, since there is space around, and even if you do, there are a lot of not-historic areas there.
