Apartment Buildings

This microscale model of three apartment buildings contains 405 pieces. Some of the details include some green space between the buildings, some window boxes, a sidewalk with street lights, part of the street, and three residents going about their day. These look like regular apartments, but something still seems strange about them. Their shape is slightly odd. Plus, isn't this supposed to be a contest where entries feature the number 15? Where is it here? Don't feel "negative" if you can't find it, though. The residents might not notice it, but I hope you do.

I built this set for a two main reasons. First, I like microscale, so I wanted to build on that scale. You don't need to build something big in order to build something cool. Second, many of the entries in this contest look like regular builds with the number 15 just slapped on them. The number isn't an essential aspect of those models. In this build, though, the number literally shapes the whole thing. Can you see why?
