This project takes on the highway as its site of investigation by merging infrastructure and architecture to address and redefine this imposed urban edge. Situated along the Boulevard Périphérique in Paris, which forms the municipal boundary of the French capital, this project proposes a single building of nearly one mile in length to unite the city with its suburb. At this scale, architecture leverages the potential of duration to address the dispersed audience of the car passing beneath the building. Thus, this project activates the filmic potential of the car; by attaching length to speed, an architecture of animation begins to emerge as one that produces a new reading of the architectural object through the movement image, creating a phenomenal engagement with architecture only previously possible in film.
