  • Above the southern skylineFrom about floor 7 — the tallest thing within 60 m to the south is 19.9 m
Drawn from the outline and roof height the Department of City Planning publishes for this building: 19.6 m over 7 floors, as the city counts them. 3 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.
