120 Fifth Avenue is a mixed-use development site in Park Slope, Brooklyn. Once completed, the 180-unit development will include:

  • 45 affordable apartments

  • Approx. 42,000 square feet of additional retail/commercial space, including a CVS pharmacy, Wells Fargo bank branch and neighborhood retail
  • A 139-space parking garage
  • A publicly accessible pedestrian plaza connecting Butler Street with Fifth Avenue

Construction Hours

  • Monday-Friday, 7:00am-6:00pm.
  • Weekend work will be scheduled as needed, typically on Saturdays from 9:00am until 6:00pm.
  • After-hours or Sunday work may be scheduled for public safety reasons or for the continuity of essential construction tasks (e.g., cement pours).

Construction Time Frame

The project’s construction team is committed to conducting work on the site in a manner that is responsible and respectful of the community while working to complete this project as expeditiously as possible and deliver the new supermarket and affordable housing units starting in 2025. We greatly appreciate the patience of our neighbors during construction.

Construction Effects

In April, May, and June, you can expect the following:

  • Modified pedestrian paths on 5th Avenue and Baltic Street adjacent to the site will allow necessary infrastructure and site work. Signage has been installed to direct pedestrians around the site.
  • The changes in pedestrian pathways resulted in the temporary removal of street parking on the west side of 5th Avenue between Sterling Place and Baltic Street, and on Baltic Street between 5th Avenue and Gregory Place.
  • Changes to pedestrian paths and parking on 5th Avenue and Baltic Street to remain until early summer 2025.
  • Truck deliveries within hours of operation. Our team has instructed truck drivers to park only where permitted; not to park in bus stops or crosswalks; not to block deliveries to local businesses or residential driveways; and to follow all applicable NYC regulations regarding idling. Our team will endeavor to minimize the impact of truck traffic.
  • Construction vehicles will access the site via vehicular gates on Baltic Street. Flagmen will be present to help ensure pedestrian safety as vehicles enter & exit the site.
