  1. Floors 2–4Homes10 homes are recorded on this lot — about 3 homes to a floor. The city does not publish which floor any of them is on.
  2. Floor 1Street levelStreet level. The lot is recorded as mixed residential and commercial, so this floor is where the commercial space is.
  • Street levelMixed residential and commercial
  • Homes10 recorded on the lot
  • Above the southern skylineFrom about floor 6 — the tallest thing within 60 m to the south is 16.2 m
Drawn from the outline and roof height the Department of City Planning publishes for this building: 12.8 m over 4 floors, as the city counts them. 2 runs of floors have something on record. The city publishes a roof height and a storey count for the lot, and nothing at all about any individual floor. What stands to the south is measured from the city’s own footprints and roof heights; it is a statement about the skyline, not a calculation of sunlight.

What is recorded here

Multiple filings, one stable building identifier.

New York City's Building Identification Number helps connect filings that may use different application numbers or describe different scopes of work. The records below are grouped because they publish BIN 3430036. They should not be read as a single construction project unless the underlying filings say so.

The matched set includes 9 new building. Its latest status categories are 7 recorded as completed, 2 approved. Each filing page preserves its own status, dates, scope and source identifier.
