How to read this street page

A shared street name does not mean a shared project.

These records are grouped by the street name and borough published by DOB. Each address remains an independent filing unless its source record explicitly connects it to another site. Use this page to scan activity along the corridor, then open an individual filing for its exact status, scope and identifiers.

The whole street

A block of Delafield Avenue, as it stands.

Each building is its own outline at its own roof height, in its own place — the gap down the middle is the street. Turn it to see the other side. The letter on a roof is the building class the city files it under.

22 of the 138 lots the city maps on Delafield Avenue — about 1,200 feet of it, the tallest 12 metres. Each building is the outline City Planning publishes for it, raised to the roof height the city measured, and placed where it stands in relation to its neighbours; nothing is arranged and nothing is to a different scale from anything else. The gap down the middle is the street. A letter is the building class the city files that building under.

Building by building

What stands on Delafield Avenue, and what is being done to it.

A filing is about a building rather than about a street, so the records here are grouped into the buildings they name. Each drawing is that building’s own footprint at its own roof height, from the outlines City Planning publishes; the panel beside it is what the tax roll records about the lot, and the last one is every filing here that names it.

138 lots are mapped on Delafield Avenue. These are the first 6, and none of them is named by a filing.
