The modernized grid-planning of cities like Manhattan has forced what we traditionally define as “nature” out from urban cores. The post natural urban landscape of Manhattan, shaped by an investment in technological progress and efficient building design, has created harsh boundaries between what we would typically call “city” and what we typically would call “nature.” Nature is either pushed to the periphery of the city, where an exact boundary line is formed, or nature is artificially embedded like in the case of Central Park, pocket parks (Paley Park), or the beautification of avenues through the planting of urban greenery. This thesis has been invested in uncovering a potential third condition that exists between the city and nature: what I define as the primitive or Urban Primitivity. The primitive confuses the boundaries between City and Nature, allowing urban forms and spatial typologies found in natural environments to approach one another and cross-pollinate…all in an effort to uncover new urban natures for a post-natural Manhattan. If one were to look at Manhattan through the lens of Urban Primitivity, plazas and lobbies can act as caves, sidewalks and floor plates can extend and merge together to create hill-like formations, and forests of columns meander, cluster, and disperse to allow for pseudo-enclosures and openings.
