Holabird & Root LLC

Holabird & Root was founded in Chicago in 1880. The firm's history since then reflects the evolution of American architecture. The full-service architecture and engineering firm is still one of the most prolific in Chicago and has maintained a reputation for creating carefully-planned and beautifully-crafted buildings. In 2006, Holabird & Root moved to the historic Marquette Building, a building the firm designed 111 years prior. In 2025, the firm relocated offices to the 8th floor to create a modern and collaborative workplace.
