This thread is in General Discussion as it is less about the example and more about the concept and its potential.And now for something completely different: A building style that focuses almost exclusively on removing detail.
In games, impostors are simpler versions of the same object which replace it when you're farther away. The detail is reduced so you can still see the object in the distance, but it's a simplified impostor which makes rendering easier. That's how any computer not owned by NASA can run GTA IV.
I intend to make a city, currently named Lyndway, designed for making videos, which uses a large amount of separate save files to make it look good up close while remaining possible to film in. It will be broken into sections, only one of which at a time will be the "real" build. All buildings, or, at the very least, their silhouettes, will remain visible in the background from any full-detail area loaded.
I used the Apartment as an example to illustrate this.

In an area with many buildings with full interiors, the effectiveness of the brick reduction and the impressiveness of the finished product will be more profound.
