What is already here?

The lot holds a 12-story office building built in 1908, on a 12,862 sq ft lot.

  1. Floors 2–12Nothing 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 126 — the tallest thing within 60 m to the south is 377.6 m
Drawn from the outline and roof height the Department of City Planning publishes for this building: 49.7 m over 12 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.

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 1015878. They should not be read as a single construction project unless the underlying filings say so.

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