  • Homes4 recorded on the lot
  • Above the southern skylineFrom about floor 7 — the tallest thing within 60 m to the south is 19.5 m
Drawn from the outline and roof height the Department of City Planning publishes for this building: 12.2 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 it sold for

1 apartment on this tax block changed hands in the year the city last published, at a median of $3,425,000.

Recorded sale prices from the Department of Finance’s rolling file, covering the year to Aug 31, 2026. Transfers under $10,000 are left out: New York records deed transfers between relatives at a dollar, and those are not sales. No apartment number and no name is carried from either side.

Lot facts come from NYC Department of City Planning, Primary Land Use Tax Lot Output (PLUTO) (64uk-42ks), accessed Sep 15, 2026. They describe the tax lot, not any single filing. When the rest of New York went up

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 3007038. They should not be read as a single construction project unless the underlying filings say so.

The matched set includes 7 alteration filing. Its latest status categories are 3 recorded as completed, 4 approved. Each filing page preserves its own status, dates, scope and source identifier.
