As bedrooms continue to replace boardrooms in the financial district, another prewar bank building is becoming a residence.

This time it’s One Wall Street, a prominent tower last occupied by BNY Mellon and most famously the longtime home of Irving Trust. Macklowe Properties is redeveloping the 50-story Art Deco edifice into a 566-unit condo, and brokers believe the building should benefit from its memorable name and address at a busy corner of Broadway.

“The location is attractive,” said Richard N. Rothbloom, an associate broker with Brown Harris Stevens who is not connected to the project but frequently works in the area and has lived there for almost two decades. “But it is a crowded market. And the question is, how different will the building be?”

Answering that question, for the moment, is not so easy.

One Wall, a limestone spire with landmark protection, is very much a work in progress. Although it was possible to appreciate views of New York Bay from its upper stories during an official tour this spring, the building’s interiors were still gutted and raw, making it hard to envision living there, and there are few renderings available. Sales are scheduled to begin in the winter, with the building slated to open in 2020.
