Keystone Building

Nestled in the heart of Aurora, Illinois, the Keystone Building stands as a testament to early 20th-century architectural innovation and the rich history of the region. As the largest private office building designed by the renowned architect George Grant Elmslie, this edifice is not just a building but a piece of living history that continues to captivate visitors and locals alike.

The History of the Keystone Building

The Keystone Building's story began in 1922 when it was originally planned as the Joseph George & Newhall Building. Before its construction, the site was occupied by the Aurora Silverplate Company, which moved out to another location, leaving behind a partially demolished building. Elmslie, who had recently parted ways with his business partner William G. Purcell, was tasked with the challenge of incorporating the remnants of the old structure into a new, grand design. This project marked Elmslie's first solo commission, and he collaborated with L. A. Fournier, an associate architect who had previously worked with Purcell & Elmslie.

The building was officially recognized by the National Park Service and added to the National Register of Historic Places on March 18, 1980. Additionally, it contributes to the Stolp Island Historic District, which was listed on September 10, 1986. The Keystone Building is not just a standalone marvel; it is part of a larger collection of Elmslie's commercial buildings in Aurora, making the city the largest repository of his work.

Architectural Marvel

Located on Stolp Island, the Keystone Building is a four-story structure that showcases the Prairie Style of architecture, a hallmark of Elmslie's design philosophy. The building's main facade stretches an impressive 165 feet along Stolp Avenue, while the rear facade is irregularly shaped to accommodate the triangular lot. The north facade measures 115 feet, and the south facade is a mere 25 feet long.

One of the most striking features of the building is its ground floor, which is dedicated to individual shops, each with its own private entryway. The main entrance is adorned with a patterned terra cotta screen, setting the tone for the intricate details found throughout the building. The first floor is divided into five major bays, separated by brick piers, with three bays north of the entry and two to the south. The upper three floors maintain a consistent exterior design, featuring double-hung windows set between brick piers. An ornamental terra cotta cornice crowns the main facade, adding a touch of elegance to the structure.

The building is constructed with brown glazed brick that contains flecks of iron, giving it unique blue and green accents. A terra cotta belt course runs above the first floor, and each of the six piers on the main facade is decorated with a terra cotta shield. These decorative shields are also found on the cornice, adding to the building's ornate appearance. Eight bronze and glass light fixtures above the first floor provide external illumination, enhancing the building's nighttime charm.

Inside the Keystone Building

Stepping inside the Keystone Building, visitors are greeted by a lobby that leads to an elevator and a staircase, providing access to the upper floors. The three upper floors are divided into office suites, each accessible from a central corridor. The fourth floor features a skylight above the lobby, allowing natural light to flood the space. The floors are made of polished terrazzo, adding a touch of sophistication to the interior.

One of the unique aspects of the building is the incorporation of the remains of the previous structure in the northeastern quadrant. This blend of old and new elements serves as a reminder of the building's historical roots and the architectural ingenuity that brought it to life.
