How to make a 1 point perspective view with the motion tweens

I'm trying to make a walking down the street view that would allow me only to use one drawing of a building and repeat it. However, whenever I try to overlap the buildings on top of each other, the further one always catches up to the newest one and then overlaps. I want to determine the correct ratios to prevent the buildings from overlapping and appearing as if they are side by side with slight gaps between them. Any help would be appreciated!
