The financing was designed to protect the interests of long-term Harlemstakeholders by making 50% of the units affordable and 50% market rate (the firsttime in New York City) with a 50% preference for existing Harlem residents.
The undulating massing is a creative interpretation of the NewYork City zoning code to provide alternating rhythm of tower andwall along the building’s 300-foot football-field length.
