The lot

What is already here?

The lot holds a 2-story condominium built in 1931, on a 3,667 sq ft lot.

  2. Floor 1Street levelStreet level.
  • Street levelWhat the lot is recorded as
  • Above the southern skylineFrom about floor 6 — the tallest thing within 60 m to the south is 15.3 m
Drawn from the outline and roof height the Department of City Planning publishes for this building: 6.5 m over 2 floors, as the city counts them. 1 run of floors has 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.

Read from the brokerages’ own published listings on September 26, 2026. A home drops off this table the next time they publish a list without it — usually because it sold or let, though a listing can also expire or be withdrawn. What we know is that it is no longer offered, which is why this shows what they have today rather than what we were told once. Everything on the market across the city.

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 3079360. They should not be read as a single construction project unless the underlying filings say so.

The matched set includes 18 alteration filing. Its latest status categories are 7 recorded as completed, 11 approved. Each filing page preserves its own status, dates, scope and source identifier.
