The conversion of One Wall Street, a building designed by prolific Art Deco architect Ralph Walker, has been underway for several years.

Developer Harry Macklowe purchased the building, which had previously served as the headquarters for the Irving Trust Company and the Bank of New York, in 2014, with the goal of turning it into apartments. Since then, the firm has been working on getting the necessary approvals, and gutting the entire thing to prep for its condo-filled future.

A new entrance on Broadway will have an undulating canopy, inspired by the curves of the limestone facade, that’s based on an unrealized design by Walker. Items salvaged from the demolition of the bank infrastructure, including vault and elevator doors, will be found in the finished building once it opens in 2020.

The block-long structure is actually made up of two separate buildings: The original 654-foot Art Deco tower, which opened in 1932, and an annex on the south side of the property that was added in 1965. The tower portion is landmarked, and the annex is not, meaning that most of the dramatic changes to the building—including a glassy addition that will serve as an entrance for retailers (including Whole Foods) and have a few of its own apartments—will be located on that end. Another addition on top of the annex will hold more apartments, as well as amenities (like a 75-foot pool, a fitness center, and a lounge) that spill over into the landmarked tower.

Once all is said and done, the building will have more than 560 condos, ranging in size from studios to four-bedrooms. Sales are expected to get underway later this year but we will not be surprised if there are delays.

In addition to beginning the process of condo construction, the firm continues to work on the annex addition, as well as a public plaza that will run along Exchange Place. The first residents are expected to arrive in late 2020, along with the Whole Foods and other retailers.
