I recently learned that they plan to make a well to supply water to the entire community, that would take a great burden off everyone, giving them free time for other activities and also reducing the wear and tear on the elevators.

On the other hand, if that becomes a reality, the biggest problem would be security. By having public institutions inside it, it cannot be closed completely, so I would make independent entrances to those entities and improve the lighting of the entire exterior.

I think that these small, but fundamental things would make a big change, since for example nobody cares about cleaning and repairing the park in the green areas, because nobody feels safe taking their children there in the afternoons.

So in summary, it would increase security so that the same neighbors are motivated to improve their common areas that they themselves will enjoy.
