text: The New York Times described this as a relatively novel design that had never been used on such a large scale, though the design did have a precedent in Philadelphia's Loews Philadelphia Hotel. The presence of the columns at ground level creates a colonnade around the lobby, which is recessed behind the upper floors. The columns rise from steel assemblies measuring  square and  thick, which are placed some  below ground level. In addition, stainless-steel flashing was placed on the facade's columns at four-story intervals, as well as beneath the spandrel panels on each floor. This reduced the amount of noise created by the wind passing through the columns. In total, over  of steel were used, more than in any other New York City skyscraper at the time except for the Empire State Building and 30 Rockefeller Plaza.
  The 11th, 31st, and 51st floors and the third basement level are mechanical floors. Each of the above-ground mechanical floors is a double-height space, with regular windows along the facade on the upper half of each floor and ventilation grates on the lower half.

  Interior spaces
  The building has about  of above-ground floor area. Each story measures , with about  of area. This made 28 Liberty Street the largest new building in New York City by floor area since the mid-1930s. The innermost two rows of columns were hidden inside the building's core, which contained its elevators and service rooms. At the time, it was not possible to completely eliminate the interior columns. Nonetheless, this provided great flexibility for the interior floor plans, which many prospective tenants desired. The floor plan was slightly asymmetrical: the southern side was ten feet wider than the northern side, with columns spaced  apart from north to south. This was because Chase officials considered the southern side of the building more desirable to work in.
