A Look Back at the Vision and Design

Fentress’ design for Denver International Airport (DEN) was recognized as a significant move beyond the conventions of airport architecture at the time. It was the first to envision an airport as an expression of the region and an answer to the needs of the passenger.  

"Fentress’ design for the terminal was inspired by the breathtaking backdrop and abundant sunshine that the site’s high plains desert environment bestowed upon the building. Initial design concepts investigated the best means to incorporate natural light and mimic the angular nature of the majestic Rocky Mountains. Extensive study involving a series of models yielded the conclusion that a fabric roof, rather than a traditional one, would not only better express the design goals, but it would also be easier to maintain and quicker to construct.  

The combination of a solid, earth-toned base with a soaring, light-filled roofing material speaks to the confluence of mountains and plains, the intersection of land and air, and the magic of flight. Similarly, the combination of efficient operational design with aesthetic vision and innovative building technologies celebrates progress and achievement while enabling the airport to achieve a timeless, enduring quality. Architecture is about light and how it is used within a space. What is special about this design is that it is simple and elegant."

Global Impact and Recognition

The airport's vast, open spaces and passenger-friendly layout continue to influence the design of airports around the globe. As does DEN’s prioritization of efficiency, natural lighting, and a seamless traveler experience. Over the years, DEN has received numerous awards and recognitions for its innovative design, passenger experience, and operational excellence. It has been named one of the best airports in North America by organizations including Skytrax and Airports Council International. 

DEN continues to lead in sustainability and efficiency, setting new standards for environmentally responsible airport operations. It is home to one of the largest solar farms at any airport in the world and has implemented comprehensive waste reduction, water conservation, and energy-efficient initiatives. The airport’s ongoing expansion projects incorporate green building principles, ensuring that future growth aligns with environmental responsibility. Its commitment to sustainability has positioned it as a global leader in eco-friendly aviation infrastructure.

The Evolution of Denver International Airport

Since its opening in 1995, DEN has undergone significant expansion to accommodate the growing demands of air travel while maintaining its original architectural vision. Initially spanning 34,000 acres, it remains the largest airport in North America by land area, providing ample space for growth. Over the past three decades, passenger traffic has surged from around 31 million annual travelers in its early years to over 77 million in recent years, prompting the terminal renovations, concourse expansions, and additional infrastructure to enhance capacity and efficiency.

Through all this growth, DEN carefully preserved the essence of its original design, ensuring that new developments remain in harmony with the airport’s iconic aesthetic. Fentress’ Jeppesen Terminal’s tent-like roof, inspired by the Rocky Mountains, remains the defining architectural feature, while new additions—such as the modernized Great Hall and expanded concourses— have been integrated seamlessly.  The result, 30 years later, is DEN cemented status as a premier international gateway prepared for the future of aviation.

Personal Reflections from Curtis Worth Fentress

“As Denver International Airport (DEN) reaches its 30th anniversary, I reflect on the profound impact this project has had—not only on the city of Denver but on airport design worldwide. From the outset, our vision was to create an airport that was both functional and inspiring, a gateway that embodied the spirit of the Rocky Mountain region. Seeing DEN thrive as one of the busiest and most celebrated airports in the world is a testament to the power of innovative, human-centered design. 

Designing DEN was a defining moment in my career, shaping my architectural philosophy and reinforcing my belief that airports should be more than just transit hubs—they should be uplifting spaces that enhance the travel experience. The iconic tented roof, inspired by the region’s natural beauty and cultural heritage, set a new standard for terminal design, proving that airports can be both highly efficient and architecturally striking. This project solidified my approach to designing dynamic, meaningful public spaces that stand the test of time.

The legacy of DEN extends far beyond its physical structure. It has influenced airport designs around the world, demonstrating the importance of sustainability, passenger comfort, and regional identity in large-scale infrastructure projects. As airports continue to evolve to meet the demands of modern travel, I am proud that DEN remains a benchmark for innovation and excellence. Its success reaffirms that thoughtful design can shape not just buildings, but experiences—and ultimately, the way people connect with the world. 

As we celebrate 30 years of Denver International Airport, I want to express my deepest gratitude to the city of Denver, the millions of travelers who have passed through its halls, and the industry partners (full list below) who helped bring this vision to life. The success of DEN is a testament to the collaboration, innovation, and forward-thinking spirit that made this project possible. It has been an honor to see the airport grow into one of the world’s leading aviation hubs, serving as a gateway to the Rocky Mountain region and beyond.”

Looking Ahead

DEN is poised for an exciting future, with ongoing expansion and modernization projects that will ensure it remains at the forefront of airport design and efficiency. As new technologies, sustainability initiatives, and passenger needs continue to evolve, the airport will continue to evolve, too.
