Construction is going vertical on 1578 Lexington Avenue, a 13-story medical office and community facility building in East Harlem, Manhattan. Designed by Kutnicki Bernstein Architects and developed by Slate Property Group and Evenhar Development Corporation, the structure will span 150,000 with facilities for Mount Sinai Health System programs. The new East Harlem Center operated by Children’s Aid will also occupy nearly 19,000 square feet across the lower levels, and a new home for Life Changers Church will sit on the ground floor and lower stories. The property is located at the corner of Lexington Avenue and East 101st Street.
Crews are finishing the ground-floor slab, which is laden with metal shoring, formwork, and rebar. The first story is in the process of being formed above street level on the western end of the property and will eventually be extended east toward Lexington Avenue. Below-grade work should finish imminently, followed by the rise of the reinforced concrete superstructure, which could potentially top out before the end of the year.

The above rendering shows the structure beginning with a five-story podium clad in gray brick and lined with a black cornice. After the sixth-story setback, the building features an envelope of gray paneling and a distinctive sloped wall on the final two levels on the northern elevation. The structure culminates in a tall bulkhead spanning the full width of the property.
The property was formerly occupied by two structures operated by Life Changers Church, as well as a basketball court for the East Harlem Center Boy & Girls Club. The buildings were demolished in 2022 and the court was razed in 2024, leaving the site vacant until construction broke ground last year.

The nearest subway from the ground-up development is the 6 train at the 103rd Street station to the north.
1578 Lexington Avenue’s anticipated completion date is slated for June 2028, as noted on site.
