Hydraulic, thermal, and social histories define the urban extent of Maiden Lane. In the revival of a past waterway, a laundromat will provide a non-gendered, climatically immersive, energy-efficient, and productive space for gathering on a neighborhood scale. The riverbed lies above two subway lines; the energy produced through trains will heat the water to designated temperatures to run the laundromat as a productive machine encased only in materials found on site. The project aims to sustainably publicize a domestic labor to curate a common investment in material care.
