Interview about Octagon Expo Pavilion, winner of the A' Architecture, Building and Structure Design Award 2025
The octagon, a geometric figure selected by Nikola Tesla for his tower served as the motivation for creating a distinctive pavilion complex. By rebuilding the tower using energy efficient technologies, with a lookout as the focal point of this architectural ensemble featuring eight pavilions within the octagonal extension of the tower, this facility would serve as a future landmark for any global expo complex. The glazed atrium, is supported by columns shaped to represent lightning. Once the Expo event concludes, this complex could evolve into a mixed-use center, guaranteeing its viability.

View Design DetailsGiven that Nikola Tesla played a significant role in illuminating the Chicago Expo of 1893, it felt entirely natural to pay architectural homage to his legacy. The Octagon Expo Pavilion draws direct inspiration from Tesla’s visionary octagonal tower concept, reinterpreting it through a contemporary lens of sustainable design and innovation. This project not only honors Tesla’s contribution to the history of science and architecture but also explores the possibility of reimagining his great tower as a symbol of clean energy, connectivity, and forward-thinking design in today’s context.
As the atrium required supporting columns, the idea of shaping them like lightning bolts naturally emerged as an extension of the pavilion’s core symbolism. These dynamic, lightning-shaped columns not only embody Tesla’s association with energy and innovation, but also serve a functional and experiential purpose. They can be illuminated during special events, transforming the structure into a spectacular light show that evokes the visual power of lightning strikes, further reinforcing the connection between architecture, energy, and inspiration.
The Octagon Expo Pavilion is intentionally organized into eight independent pavilion segments, each approximately 370 square meters. With a gross surface area of 15,000 square meters, including a glazed atrium courtyard and a green roof terrace, this modular layout provides maximum functional versatility and supports the accommodation of a wide range of Expo-related programs and services. By employing a hierarchy of spaces and varied volumetric scales, the design fosters a sense of human proportion and experiential intimacy within the larger monumental framework, while ensuring clear circulation paths and maintaining overall architectural coherence across the complex.
Adaptability is a central, multifunctional quality of the Octagon Expo Pavilion. The design anticipates the building’s post-Expo lifecycle, allowing it to be efficiently transformed into residential, office, or mixed-use spaces. This flexibility not only extends the functional lifespan of the structure, reducing the environmental impact associated with demolition and reconstruction, but also promotes long-term sustainability. By enabling the pavilion to respond to evolving community needs, the project ensures continued social and economic integration, creating a dynamic, living asset rather than a single-purpose exhibition venue.
The Octagon Expo Pavilion balances historical homage with cutting-edge sustainability by integrating Tesla-inspired symbolism with advanced energy-efficient technologies. The tower features a solar-panel glass façade, promoting Nikola Tesla’s vision of green energy and efficient power use, while an integrated water recycling system ensures responsible management of resources within the pavilion. Additionally, the sensor-controlled operable roof over the atrium enables natural ventilation, reducing reliance on mechanical systems. Together, these strategies honor Tesla’s legacy while demonstrating how historical inspiration can coexist with contemporary sustainable architecture.
The observation platform, situated at the highest point of the tower, functions as a multifunctional space that offers visitors a panoramic view of the entire Expo site. From this elevated perspective, users can fully appreciate the architectural composition, spatial organization, and landscape integration of the pavilion and its surroundings. By providing both a visual and experiential vantage point, the platform enhances engagement with the design, allowing visitors to understand the scale, rhythm, and interconnectedness of the complex in a way that ground-level views cannot.
The Octagon Expo Pavilion is organized into eight individual pavilions, all accessible from the central atrium, which serves as the primary circulation hub. This layout ensures seamless connectivity both between the lobby and each pavilion and from pavilion to pavilion, while also allowing direct access from the courtyard to the individual pavilions. The design prioritizes efficient flow and intuitive wayfinding, creating a user experience that is both cohesive and flexible, enabling visitors to navigate the complex naturally while enjoying clear visual and spatial connections throughout the site.
The glass atrium serves as the central focal point of the pavilion, acting as a lobby that seamlessly connects the eight pavilions with the tower. Beyond its spatial and visual significance, the atrium enhances the building’s environmental performance: its roof is sensor-controlled to open automatically in response to external weather conditions, enabling natural ventilation and reducing reliance on mechanical systems. At the same time, the atrium enriches the experiential quality of the space, filling it with natural light and creating an open, airy environment that emphasizes connectivity and transparency throughout the pavilion.
The Octagon Expo Pavilion embodies a bridge between Tesla’s era and contemporary innovation, offering a dynamic environment that can inspire future generations of scientists and innovators. Its ground floor is designed for exhibitions, showcasing technological advancements and historical achievements, while the second floor can function as a research and innovation center, fostering creativity and experimentation. The tower houses office spaces, supporting focused work and collaboration, and the observation platform at the top provides the public with a panoramic perspective, encouraging engagement with the building and its surroundings. By combining educational, professional, and experiential functions, the pavilion demonstrates how architecture can actively support knowledge, creativity, and inspiration.
While the Bronze A’ Design Award is an honor, it does not fully reflect the significance of Tesla’s vision embodied in the Octagon Expo Pavilion. This design is a unique, multifunctional space rooted in the octagonal geometry of the tower and pavilions—a shape traditionally associated with positive energy, particularly in Chinese culture. In this context, the award ranking does not fully capture the conceptual strength, innovative spatial strategies, and formal quality of the project. Nonetheless, the recognition reinforces the importance of integrating symbolic meaning with architectural functionality, a principle that continues to guide my current and future projects.
