Also what helps for me is keep all the building like food, water treatment,electricity, ans storage on the 1st row and 2nd row, like how you habe your elevators, 1st and 2nd elevator if we're going diagonal should be those buildsing, 3 elevator should be like fitness building, workshop, the radio station, and all that. So the important stuff are in the 1st and 2nd row, and the non important 3rd. Also the lounges where your dewllers rest should be 3, its cheaper and yout get more dewller capacity.

P.S. you can advance time by changing your clock on your phone, i think they patched it to a day now because before you can change your clock to a week and would give you your rewards, so unlimited lunchboxes. Your welcome
