Lyon Avenue

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.

No Department of Buildings filing names Lyon Avenue, and the city maps its buildings anyway. Each drawing is that building’s own footprint at its own roof height, from the outlines City Planning publishes, and the panel beside it is what the tax roll records about the lot.

54 lots are mapped on Lyon Avenue. These are the first 12, and none of them is named by a filing.
