With the emergence of new technologies and new environmental challenges, the urban landscape and social behavior have seen a tremendous shift in the last several years. On the contrary, the way our street blocks are designed has stayed largely the same for more than a hundred years (storefronts, sidewalks, curbs, street parking, and roads). Autonomous Block challenges this stagnant, fixed block typology by suggesting a dynamic ground plane that can self-transform to respond to various urban and social issues (i.e. – rising sea level, lack of public space, inequality, etc.). By integrating autonomous dolly robots with a series of moveable streetscape furniture and mobile program typologies, Autonomous Block envisions a new urban system that makes the ground level of our cities more livable, resilient, and efficient.
