601 is the east household and 604 is the west household. 602 and 603 are middle households.
The east door and west door are open to the north and south, and the middle door faces south.
The light well is actually empty and belongs to the external space. To the north is the corridor, which connects the entrances of the four households to the stairs and elevators.
This floor plan is a common floor plan. This arrangement makes the central room transparent from the north to the south. Can't say whether it's good or not.
Generally, 601 is better, with transparency to the north and south while avoiding western exposure.
You have included elevators and stairs, so there are too many circles. Corridors, elevators, front rooms, stairwells, etc. are all part of the public house.
If the corridor is made into a closed type, the so-called north-south transparency of the middle house will not be true; if the corridor is made into an open type (channel + railing), the danger of this area will increase. . The two sides of the elevated corridor (light well and outside) become ideal jumping areas.
