One Wall Street Completes Monumental Residential Transformation The Luxury Lifestyle Magazine celebrated the completion of One Wall Street with a story highlighting the record-breaking residential tower’s many amenities and art-deco flourishes. The Harry Macklowe-developed tower is the largest office-to-residential transformation in New York City history and preserves the original Irving Trust Building’s heritage while bringing the interiors up to modern luxury specs, including high-end appliances, hardwood flooring, and large windows with intimate Downtown views. Residents also have access to the exclusive One Club, where they can work up a sweat in the state-of-the-art fitness center, rejuvenate in the resort-style spa, or catch up on some work in the expansive One Works coworking space, all without leaving the comfort of their own building.
