Jean Nouvel’s proposed skyscraper located adjacent to the MoMA in New York would dominate the midtown skyline rising 75 stories, or the approximate length of about 5 city blocks in Manhattan. A city block thrives spatially through formal variation, however, the standard Manhattan skyscraper resists such change, offering only self-similar repetition and minimal scalar deformation. Why do we allow such boring spans in the vertical dimension when we demand vibrancy and transformation across the same span in the horizontal dimension? Migrating Formations is a tower proposal that rejects this ideal, offering an alternative design for the 75-story MoMA tower. Our design proposes a continually shifting mediation of two systems. Always coexisting, these two systems compete for dominance, continually reforming their relationships based on this symbiosis as well as outside forces of the city. The structural system gives cadence to the vertical organization, shifting in scale and fluctuating between horizontal and vertical expression. The second system encloses the first, tiling to provide flat surface or pulling inside to provide spatial interaction. The overall effect of the tower is one of constant interplay between pure surface and revealed space - creating moments of intensity that reveal something of the individual nature of the two systems. This results in dramatically different interior spaces that can provide for a multitude of programmatic functions.
