In the 39 years its record reaches back, the lot has drawn 1,134 separate government filings — a paper trail nearly as tall as the building itself.

The pace is anything but even. The early decades pass in near silence; the filings cluster heavily in recent years, peaking in 2012.

On the environmental ledger, the building posts an Energy Star score of 55, with a site energy-use intensity of 77.5 kBtu per square foot. Its operations answer for roughly 2,322 metric tons of CO2-equivalent a year.

Read together — 24% mortgage, 39 years of accumulation, a parcel of New York — these scattered records compose a portrait of the address that no single page sets out to draw.

$4.3M of New York, written across 1,134 government filings.
