CAR and SHELL or Marinetti’s Monster, recently awarded second place in the 2014 eVolo Skyscraper Competition, asks pertinent questions about an "insatiable" desire for growth in urban centres. Based on the premise that we "can no longer stand idly by and watch our cities consume themselves with an anxious need for expansion", Daniel Markiewicz and Mark Talbot's proposal seeks to demonstrate what a "city in the sky" could look like in suburban Detroit. The project is conceived as a vertical neighbourhood, or "a rich vertical urban fabric." Three main grids (streets, pedestrian pathways, and structure) are intertwined to create a box-shaped wireframe to which traditional/contemporary houses and other diverse programs (such as recreational and commercial areas) can be plugged in.
