The new addition to the PS 46 Q Alley Pond, located on a shared NYC park playground, addresses programmatic and accessibility needs while housing classrooms, special education, administration, and a new dining room. It incorporates Passive House energy conservation measures, including enhanced insulation, thermal bridging mitigation, and triple-pane windows for sustainability. The project also renovates the existing building for full accessibility and uses a precast façade system to accelerate construction and reduce material waste.
