As it stands today, the Stambaugh Building is the result of two distinct building phases. It began as an eight-story tower with a concrete and steel frame that cost $1.5 million to construct. With a white brick facade and a cornice adorned with an intricate trim, it is an outstanding example of how Kahn paired historical styles with industrial materials. The interior included terrazzo floors, marble walls and stairs, and brass hardware; the windows were framed with grained walnut; a Cutler Mail Chute system was installed throughout.

The administrative offices of the Youngstown Sheet and Tube Company occupied the top five floors of the Stambaugh with Euwer’s Department Store installed in the lower three levels and basement. A sign for Euwer’s, which opened as a retailer in 1908, crowned the Stambaugh tower. Once the building reached full capacity, the building owners decided to expand the structure vertically, and for approximately $200,000 they added four new floors. The steel frame grew in height by 60 feet, requiring that the cornice be removed; once completed, the structure topped out at 160 feet.

Another Kahn-designed building sits diagonally across the central square in downtown Youngstown. The thirteen-story Mahoning National Bank building has a strong vertical emphasis and an elaborately detailed, classically styled terra-cotta facing topped with an ornate cornice.

Following a renovation that began in 2015, the Stambaugh Building now houses a DoubleTree by Hilton, in addition to a restaurant and retail stores. The hotel opened in 2018.
