The building is a four-story red brick building, U-shaped around a small courtyard. A foundry was at ground level on the north side of the courtyard. The building’s foundation is made of stone with brick bearing walls and cast-iron interior columns. The building’s classical revival exterior includes arched doors and windows with semicircular brick arches and hoodmoulds. Entrances are asymmetrical with the main entrance located on Fulton Street. Originally, the first floor space was used for retail with the third and fourth floors leased to other manufacturers. Gradually, Gurley expanded to use the entire buildings.
