The lot

What is already here?

The lot holds a 34-story office building built in 1928, on a 83,937 sq ft lot.

  1. Floors 2–34Nothing on record
  2. Floor 1Street levelStreet level. The lot is recorded as commercial and office, so this floor is where the commercial space is.
  • Street levelCommercial and office
  • Above the southern skylineFrom about floor 56 — the tallest thing within 60 m to the south is 166.8 m
Drawn from the outline and roof height the Department of City Planning publishes for this building: 142.6 m over 34 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.

The apartments

538 condominium apartments are assessed on this block, and the typical one is 1,360 sq ft (126 m²). They run from 29 to 608 m².

The city values the typical one at $476,868. That is the Department of Finance’s market valuation for tax, not an asking price and not a sale.

What it sold for

7 apartments on this tax block changed hands in the year the city last published, at a median of $3,800,000, from 1,537,500 to 9,065,000.

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.

As the assessment roll records it. Only owners that read as a company are shown here; where the roll names an individual, nothing is published.

Lot facts come from NYC Department of City Planning, Primary Land Use Tax Lot Output (PLUTO) (64uk-42ks), accessed Sep 30, 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 1016880. They should not be read as a single construction project unless the underlying filings say so.

The matched set includes 21 alteration filing. Its latest status categories are 18 approved, 2 recorded as completed, 1 under review. Each filing page preserves its own status, dates, scope and source identifier.
