Construction is rising on 1522 First Avenue, a 30-story medical office building in the Yorkville section of Manhattan’s Upper East Side. Designed by Perkins Eastman and developed by Extell Development Company, the structure will yield 400,000 square feet of Class A office space and retail space on the ground floor and cellar levels. The Hospital for Special Surgery has signed on as the anchor tenant and will occupy 200,000 square feet across the first eight stories of the building. Ancora Engineering is the engineer of record and Lendlease is the general contractor for the property, which is alternately addressed as 403 East 79th Street and located between East 79th and 80th Streets.
Foundation work was still progressing at the time of our last update in mid-May. Since then, construction reached street level and the reinforced concrete superstructure now stands two stories high above the wraparound sidewalk shed. A tower crane has been erected to aid in the vertical progress, and a truck with a telescopic boom was seen delivering concrete to the inner sections of the building’s footprint.
The main rendering depicts 1422 First Avenue rising from a multi-story podium with several setbacks, followed by a rectangular tower capped with a flat roof parapet. The façade will be composed of white paneling framing a grid of floor-to-ceiling windows arranged in two- to three-story increments, and the crown features a pattern of tall dark metal grilles.
The below rendering shows the southern corner of the structure, where the lower levels are enclosed with more expansive sections of glass.
The Hospital for Special Surgery’s new facility will feature offices and treatment rooms for musculoskeletal conditions, and will be fitted with enhanced ventilation and filtration systems. The programming also includes space for the offices of the Department of Health, as well as room for ambulatory care and surgical facilities. The nearest subway from the development is the Q train at the 86th Street station, located at the corner of East 83rd Street and Second Avenue.
1422 First Avenue’s anticipated completion date is slated for the fourth quarter of 2024, as noted on site.
