This seven-story mixed-use supportive housing project in the Yorkville section of the Upper East Side was developed by Azimuth Development, RiverOak Investment Corporation, and the nonprofit Women in Need. All residential units are two-bedrooms and they are geared towards single mothers who are homeless. The building also includes 6,000 square feet of space, across the ground and cellar levels, for the daycare facility Sunshine Early Learning Center. The facility provides social services to its residents including employment assistance, case management, and child care. 

Madsen Engineering worked with the developer to produce the most cost-efficient design while working with the constraints of the lot and the neighboring properties. The full design was provided for two structural systems – composite lightweight concrete on metal deck floor slabs supported by a steel structure and flat-slab cast in place concrete. After pricing both options, the developers decided to proceed with the concrete structure. The building is supported by a partial mat/spread footing foundation
