Excavation is moving along at 930 First Avenue, the site of a 29-story residential building in the Turtle Bay section of Midtown East, Manhattan. Designed by Leandro Nils Dickson Architect for the 51 Street De Owner LLC, the 335-foot-tall structure will yield 83 condominium units with an average scope of 645 square feet. The project will also include 3,465 square feet of commercial space and a 20-square-foot rear yard. The property is alternately addressed as 401-405 East 51st Street and located at the corner of First Avenue and East 51st Street.

The following axonometric diagram was recently posted to the construction board, providing a full preview of the upcoming development. The drawing closely matches the above rendering, showing the structure beginning with a six-story podium topped with a wraparound terrace. The main tower then rises with a monolithic massing up to a flat roof with a bulkhead extension. The podium features smaller rectangular windows, while the tower above has larger floor-to-ceiling windows grouped in a two-story grid. Loggia terraces are shown at the southeast corner of the final two stories. The loggias with hanging vegetation at the midpoint of the tower appear to have been scrapped in favor of mullion-free glass panels on the southern elevation and shallow balconies on the western face.

Work has progressed below grade since our last update in April, when demolition was still finishing up on the final remaining occupant of the assemblage at 936 First Avenue. This building, along with the others at 401 to 405 East 51st Street, have been fully cleared and excavation and pilings are now taking place. Foundations will likely finish up in the next couple of months, and the new superstructure could potentially emerge above street level before the end of the year.

A list of residential amenities has yet to be disclosed. The nearest subway from the development is the 6 train at the 51st Street station along Lexington Avenue to the west.

930 First Avenue’s anticipated completion date is slated for August 1, 2027, as noted on site.

  1. 20 Square foot back yard the size of a small dumpster?

      Perhaps it could be improved if the enclosure of the water tank and elevator machinery was made in the form of a turtle.

  3. Is the average condo size in this development really less than 700 square feet? For condos of course that’s just tiny.

    My understanding is that between the envelope of the previously existing building and the air rights that came with it, this development had about 112K square feet to work with. I imagine they filled that envelope.

  4. hate to loss pre-wars but, just looked on old google maps, the prior buildings were basic at best.

    good site to develop

    but come on.. ……this is not great design.

    Hire RAMSA and get double on the price per foot.

    incredibly short sighted of you developer

    • you think ppl will pay 4k+/sqft in Turtle Bay lol?

      • they would pay $2000+ yes for new construction.

        You dont think people in Turtle Bay (Sutton place adjacent) dont deserve nice looking limestone buildings, got it.

        • lol dude there’s a 100% gap between 2k/sqft and 4k/sqft. People who can spare 5-6M for 2br don’t pick Turtle Bay as their top choices. Ofc I’d love to see RAMSA-quality bldgs everywhere but then everything will be twice more expensive
