AT&T Michigan Headquarters

The AT&T Michigan Headquarters is an Art Deco skyscraper in downtown Detroit located at the intersection of 1st Street, Cass Avenue, State Street, and Michigan Avenue. The complex comprises several connected buildings that together form a prominent, unified presence in the city's skyline.

The original building was constructed in 1919 with seven stories and received a twelve-story addition in 1928 to support the rapidly growing telecommunications business. A maintenance facility was added in the 1950s, followed by another major expansion in 1973.

The exterior displays bronze panels with lightning bolts, bells, and communication symbols that represent the progress of telephone technology. These decorative elements cover the facade and reflect how people once saw telecommunications as an exciting innovation.

The building sits in the heart of downtown and is easily accessible on foot with good public transit connections nearby. The best views of the facade with its distinctive bronze details can be seen from the surrounding streets, particularly from State Street.

The building was designed with hidden floors and special structural elements to allow for future vertical expansion. This reflects how the company invested in its own growth and planned ahead for what it anticipated would be decades of expansion.
