O’Hare International Airport in Chicago stands as a beacon of modern architecture and efficient air travel. Designed by leading firms like Skidmore, Owings & Merrill (SOM) and Studio ORD, the airport has undergone significant transformations to integrate both international and domestic operations seamlessly.
The latest expansion introduces a “tree-like” structural system and a vaulted roof, showcasing innovative design solutions that enhance the travel experience.
Mayor Brandon Johnson recently unveiled SOM’s design for a major expansion. This includes a new satellite concourse connected to the main terminal via a bridge to Concourse C of Terminal 1.
The design brings both aesthetic appeal and functional improvement, making Chicago O’Hare not just a transit point, but a landmark in architectural excellence.
Part of an $8.5 billion investment, the new facilities at O’Hare aim to meet the growing demands of one of the world’s busiest airports.
The expansion project, which is the largest in O’Hare’s history, focuses on creating a space that improves passenger flow and provides a more enjoyable experience.
From its innovative structural systems to its seamless integration of various operations, O’Hare International Airport is setting new standards in airport architecture.
Historical Context and Evolution of O’Hare
Chicago O’Hare International Airport, originally known as Orchard Field, began as a manufacturing base during World War II. In the post-war era, it evolved into a commercial airport to meet Chicago’s growing aviation needs.
The airport was renamed in 1949 after Edward “Butch” O’Hare, a US Navy aviator. O’Hare’s expansion was driven by the rise of jet aircraft, making it a critical hub in the Midwest for national flights.
Key milestones need highlighting:
- 1963: JFK’s dedication marked the airport’s significance.
- 1950s-1960s: Major expansions to accommodate increasing air traffic.
- Present day: Expansive terminals and modernized infrastructure.
The Chicago Department of Aviation has spearheaded multiple projects to improve O’Hare’s facilities.
Recently, the eastern extension of Terminal 5 added nearly 350,000 square feet and enhanced capacity by 25% to reduce delays and increase efficiency.
Under Mayor Rahm Emanuel, O’Hare launched a significant redevelopment plan that included public feedback.
This plan aimed to enhance passenger experience and reinforce the airport’s status as a global hub.
O’Hare Airport continues evolving to address modern aviation demands, ensuring it remains a cornerstone of Chicago’s connectivity and economic vitality.

Master Plan and Architectural Vision
The expansion of O’Hare International Airport in Chicago is a comprehensive project aimed at modernizing infrastructure and enhancing passenger experience.
Key elements include the innovative design concepts of the Oculus and Atrium, the ambitious Global Terminal Project, and a strong emphasis on sustainability and environmental integration.
Oculus and Atrium Design Concepts
The expansion features the Oculus and central atrium design concepts, bringing light into the airport’s core.
The Oculus serves as both a skylight and a focal point for public spaces. It uses Skylights to flood the atrium with natural light, creating an inviting atmosphere.
Santiago Calatrava was one of the architects who influenced this design, known for integrating structural elegance with functionality.
The atrium itself follows the architectural vision of large, open spaces, emphasizing the shell-like roof structure.
The Global Terminal Project
The new Global Terminal, part of an $8.5 billion expansion, replaces the outdated Terminal 2.
SOM, along with Ross Barney Architects and Juan Gabriel Moreno Architects, leads the project focusing on international travel and enhanced passenger flow.
Studio ORD, led by Jeanne Gang, won the international design competition for this terminal.
Their Y-shaped structure converges on a central atrium, which draws inspiration from the city’s Municipal Device. This terminal will serve both international and domestic flights, aiming to streamline connections for travelers.
Sustainability and Environmental Integration
Sustainability is a core focus in the O’Hare expansion.
The design incorporates green technologies to reduce environmental impact, making use of energy-efficient systems and sustainable materials.
The project emphasizes minimizing the carbon footprint through smart construction techniques.
Arup, an engineering firm known for its sustainable approach, plays a crucial role.
The airport integrates green spaces and features that align with Chicago’s wider environmental goals.
This includes rainwater management systems and energy-efficient lighting, aimed at creating a modern, eco-friendly airport environment.
Infrastructure and Functional Design
Chicago O’Hare International Airport has undergone significant changes to improve operational efficiency and enhance the passenger experience.
The focus has been on creating a seamless flow for travelers, integrating new satellite concourses, and upgrading the main terminal area.
Terminal Area Plan and Passenger Flow
The recent expansion features a detailed terminal area plan aimed at improving passenger flow.
Security checkpoints, ticketing areas, and baggage claim zones have been restructured to reduce congestion and enhance operational efficiency.
High ceilings and a vaulted roof structure in the terminal create an airy space, enhancing visibility and natural light.
The design also incorporates trees within the terminal to provide a more pleasant environment.
Wayfinding has been upgraded with clearer signage to help travelers navigate the expansive terminal effortlessly.
These improvements significantly enhance the passenger experience, offering a more frictionless experience from check-in to boarding.
Satellite Concourses and Connectivity
The addition of new satellite concourses connects seamlessly with the main terminal via bridges, improving connectivity.
These concourses include modern amenities and design features aimed at improving airline operations and passenger comfort.
Concourse C, now connected via a bridge, benefits from structural systems that support high ceilings.
This design facilitates better air circulation and daylighting strategy, helping to reduce the terminal’s carbon footprint.
For airlines and carriers, improved gate lounges and additional gates enhance domestic operations and overall efficiency.
New seating areas and gate lounges are designed to accommodate more passengers comfortably.
The use of natural light helps brighten these spaces, contributing to a pleasant waiting experience.
Impact and Future Development
The expansion of O’Hare International Airport is set to transform air travel in Chicago with new infrastructure and more efficient operations.
Important highlights include increased economic benefits and detailed timelines for upcoming milestones.
Economic and Operational Outlook
The Chicago Department of Aviation expects the O’Hare expansion to significantly boost the local economy.
With 19 new gates, the plan enhances the operational efficiency for various airlines, including American Airlines.
This upgrade aims to reduce layover transfers and handle more aircraft sizes, improving overall passenger experience.
Mayor Rahm Emanuel has consistently championed this project.
It is anticipated to create thousands of jobs during construction and operation phases. Moreover, better connectivity thanks to features like the bridge to Concourse C of Terminal 1 will enhance O’Hare’s standing as a major international hub.
Expansion Milestones and Projected Completion
The first stage of the expansion, including the development of Satellite Concourse 1, began in 2023. This phase is projected to be completed by the mid-2020s.
The concourse will feature designs from renowned firms such as Solomon Cordwell Buenz and will include a striking “tree-like” structural system.
Further plans involve modernizing Terminal 2, incorporating a dramatic shell-like roof. The establishment of facilities like Satellite One will cater to international flights.
The entire Terminal Area Plan is designed to be completed in stages, ensuring minimal disruption to current airport operations.
