I thought you might like to see a couple of modular buildings and MOCs laid out in a city layout.
Each level represents a specific cross section of the town. While they are not physically linked, they are connected in concept, relative position and imagination. So, each cross-section is part of the same city.
Seen in its entirety, the multi-level display represents a logical overview of a large town; relative to the small area space it takes up. It consists of approximately 62,000+ pieces with a total of over 50 sets/ MOCs and more than 150 MiniFigs.
Most of the sets displayed are official LEGO sets but have been modified in one way or another, some more drastically than others. There are also a significant number of MOCs (my own creation) and custom builds.
If you like, you can watch a city overview with commentary:
