Construction is underway on the conversion of One Wall Street, the landmark fifty-story limestone Art Deco tower located on an entire block at the intersection of Broadway and Wall Street in the Financial District. Developer Macklowe Properties is converting the Ralph Walker designed office tower into residential condo and rental units with retail at the base. The tower was completed in 1931 and then expanded in 1963, bringing its total gross floor area to 1.1 million square feet.

At the top of the tower, the 49th floor Observation Room features amazing views of Lower Manhattan and a ceiling clad with shells from the Philippines. The space was originally used for formal meetings under the prior office program.
