The lot

What is already here?

The lot holds a 3-story two-family home built in 2025, on a 3,000 sq ft lot.

  1. Floors 2–3Homes2 homes are recorded on this lot — about one home 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 one and two family homes.
  • Street levelOne and two family homes
  • Homes2 recorded on the lot
  • Above the southern skylineFrom about floor 7 — the tallest thing within 60 m to the south is 20.1 m
Drawn from the outline and roof height the Department of City Planning publishes for this building: 9.4 m over 3 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 3429142. They should not be read as a single construction project unless the underlying filings say so.

The matched set includes 20 new building, 3 alteration filing. Its latest status categories are 8 recorded as completed, 7 closed or withdrawn, 8 approved. Each filing page preserves its own status, dates, scope and source identifier.
