Excavation is underway at 1487 First Avenue, the site of an upcoming 24-story residential building on the border of Lenox Hill and Yorkville on Manhattan’s Upper East Side. Designed by Hill West Architects and developed by Carmel Partners, which purchased the property for $73.5 million in early 2022 from local developer Robert Chou. Previous figures put the height and floor count at 209 feet tall and 24 stories, though a new rendering spotted on site shows a much taller revision. It was last reported that there will be 94 condominium units with an average scope of around 1,900 square feet, 7,120 square feet of ground-floor retail space, and a cellar level. CP VII 78th Street Owner is the owner and Carmel Construction East is the general contractor for the project, which is located at the southwestern corner of First Avenue and East 78th Street.
