The lot

What is already here?

The lot holds a 60-story condominium built in 2020, on a 61,719 sq ft lot.

  1. Floors 26–60Above the southern skylineAbove the tallest building within sixty metres to the south, which stands 75.2 m. Nothing on that side reaches this floor.
  2. Floors 2–25Nothing on record
  3. 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 26 — the tallest thing within 60 m to the south is 75.2 m
Drawn from the outline and roof height the Department of City Planning publishes for this building: 274.9 m over 60 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.

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 Oct 23, 2026. They describe the tax lot, not any single filing. When the rest of New York went up

Violation record

Are there open violations here?

No open violations are recorded for this building. 10 notices are on file, all with a recorded resolution.

Open means the agency has not recorded a resolution, which is not the same as the problem still existing. What a violation is, and what it is not. From NYC Department of Buildings, DOB Violations (3h2n-5cm9), accessed Oct 23, 2026.

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 1089694. They should not be read as a single construction project unless the underlying filings say so.

The matched set includes 17 alteration filing. Its latest status categories are 12 approved, 5 recorded as completed. Each filing page preserves its own status, dates, scope and source identifier.
