The following images are of a schematic massing study I recently completed. The buildings are two duplexes for which I was tasked with taking the 2D drawings and creating first a massing model and then a simple street scene.
Below is the first image I prepared. This is the massing study without color, prepared to enable an understanding of the design in 3 dimensions.
This is the final image. Here I have added some color selections from the designer and placed street trees and a few scale people.
