Answer: I do not know. Today they build such houses with large rooms on the first floor: an equipped gym, rooms for holding all kinds of events (birthdays and others), a place for mother and child. If necessary, you can organize a kindergarten there and anything you want.
After all, they do try to equip high-rise buildings like small cities so that you would barely need to leave them.
I think that nature will eventually force people to respect the environment more and more and in accordance with the relationships between people, houses will be planned that will meet the trends toward rapprochement and distancing between them.
However, it is not easy. First of all, we need to educate people, and then in accordance with the level of their perception of the correct education, when they become more suitable for each other, we can somehow arrange them into groups.
Once in Moscow, they tried to build high-rise buildings for certain types of people: for architects, or musicians, or engineers, and so on. In our time, however, I do not know.
It is hard to say what the cities of the future will be like. People will begin to feel a spiritual need for being close to each other in order to feel more connected and draw spiritual elevations from it, not in the form of floors, but in the form of spiritual ascent. There is room for a stretch of the imagination here.
