Hello, a great idea for fashion!
But I think it is not passable, there are too many random things (safes, lockers, their number is random) the lack of the possibility of farming on a bloody night, the constant fear that zombies will demolish the 1st floor and the building will collapse. It does not work to repair the building, you need a very large level for this. I suggest adding traps and Molotov cocktails to the boxes or some loot, adding boxes with beds or putting somewhere higher beds for the base (VERY LITTLE LAND for creating beds and growing food) Add a box at least 1 with frames to fix the 1st floor.
1) leave it as it is and add boxes
2) change so that not only the boxes are updated, but the entire floor is updated (including all the decorations)
3) add 3 more to the new building (square) 1 building is connected by 2 cranes from different sides the following buildings are connected by a bridge on the 1st floor (so that each time it was necessary to walk the whole building entirely) and you have a choice to appear after passing 1 building, you had a choice which building to go to. And turn off the recovery of production
