The lot

What is already here?

The lot holds a 11-story educational building built in 1920, on a 100,866 sq ft lot.

  1. Floors 10–11Above the southern skylineAbove the tallest building within sixty metres to the south, which stands 29.7 m. Nothing on that side reaches this floor.
  2. Floors 2–9Nothing on record
  3. Floor 1Street levelStreet level. The lot is recorded as public facilities and institutions.
  • Street levelPublic facilities and institutions
  • Above the southern skylineFrom about floor 10 — the tallest thing within 60 m to the south is 29.7 m
Drawn from the outline and roof height the Department of City Planning publishes for this building: 53 m over 11 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 3335892. They should not be read as a single construction project unless the underlying filings say so.

The matched set includes 20 alteration filing. Its latest status categories are 12 approved, 2 under review, 6 recorded as completed. Each filing page preserves its own status, dates, scope and source identifier.
