Metathesis is an exploration that is anchored in ideas of reactionary potential. The pedagogical investigation challenges and dismantles notions of containment and configures an approach to P.S. 64 that questions ideas of standardization, spatial coding, and the embodied sensorial experience within the school. My intervention aims to dismantle physical and conceptual thresholds of space across scales of the urban fabric, the body, and the particle. This recoding of how the building dialogues with various reactionary agents catalyzes a spatial scheme that retranslates the kinetic potential of substance, ideas, and sensorial output associated with programmatic specificity. The building becomes a space where sights, sounds, smells, and substances infiltrate through wall, floor, and facade in a system of exposure and diffusion that produces warps, impressions, and interstitial space for new forms of occupancy and interaction between programmatic conditions.
