The lot

What is already here?

The lot holds a 2-story office building built in 1926, on a 23,900 sq ft lot.

  1. Floor 2Nothing 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 4 — the tallest thing within 60 m to the south is 11.3 m
Drawn from the outline and roof height the Department of City Planning publishes for this building: 15.6 m over 2 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.
