>First, build the apartments in a ring around the city blockThe parts of eastern europe that contain commie blocks aren't organized into city blocks. They were planned outside of cager culture so they are walkable with no need for blocks. pic related is the area i lived in as a child. the thick lines are 4 lane roads, 6 when yellow, the thin white are 1 lane. A "block" as defined by car-practical roads in this case is about 4 km in diameter with several grocery stores within the block.
>The center of this block is only accessible to residents: fill this space with a small park, playground, storage, parking, or something else.yeah that's how they were designed to begin with.
>On the ground floor of the blocks, facing outside, are various shops, accessible to anybody. Privately owned ground level shops are not uncommon, but are more likely to be services like a hairdresser, seamstress, etc. To be clear "ground level" units are uncommon in Khrushchyovkas, the type of building everyone i knew lived in.
>the whole structure is small enough that you could know most of the other residents and therefore trust your kids to play in the courtyard without risk.Risk of what? someone grabbing your kid and taking them up 5 flights of stairs? Everyone can see and hear children playing in the courtyard. More units means 2% more bad guys, but 100% more people keeping an eye out.
Maybe your experience of eastern europe was zoned differently, but as far as i know that was pretty centrally planned.
