About Octagon Expo Pavilion

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.

Dr Aleksandar Rudnik Milanovic's Octagon Expo Pavilion represents a compelling synthesis of structural innovation and civic monumentality within contemporary exhibition architecture, demonstrating sophisticated command of vertical composition, geometric articulation, and atmospheric integration that positions this work within evolving traditions of observation towers and expo landmarks that seek to create memorable silhouettes and landmark presence while accommodating complex programmatic requirements across multiple levels. The design achieves notable formal clarity through its tripartite organizational strategy, establishing distinct visual and functional zones through the grounded horizontal podium, the soaring cylindrical tower shaft, and the distinctive octagonal crown that provides compositional culmination and symbolic apex, each component legible yet integrated within a coherent architectural statement that balances monumentality with accessibility, technological expression with human scale. The structural system demonstrates admirable transparency and honest material expression, the external diagrid framework functioning simultaneously as primary structural support and architectural character-defining element, its geometric discipline creating rhythmic visual interest across the tower's substantial height while the lattice's openness maintains visual lightness despite the structure's considerable mass, suggesting engineering confidence and material efficiency consonant with contemporary sustainable design values that celebrate minimal material achieving maximum structural performance. The podium's extensive glazing and terraced massing creates welcoming transparency that invites public engagement, the illuminated interior floors visible through curtain wall systems suggesting active programming and institutional vitality, the setback tiering mediating gracefully between the tower's vertical thrust and the plaza's horizontal expanse, establishing transitional spatial hierarchy that guides visitor experience from approach through entry toward vertical circulation within the tower core. The octagonal crown introduces geometric specificity and cultural resonance, the eight-sided form carrying symbolic associations across multiple traditions while providing practical benefits for observation platform planning and 360-degree viewing opportunities, its crimson coloration creating memorable visual signature and chromatic accent that enhances recognition and landmark identification from distance, the saturated hue suggesting celebration, energy, and institutional presence while providing dramatic contrast against typical sky conditions whether clear blue daylight or twilight's deeper tones. The plaza activation through populated foreground demonstrates understanding of successful public architecture's dependence upon social animation and human-scale design, the generous hardscape accommodation of casual gathering, promenade, and social encounter transforming the structure from isolated object into genuine civic amenity, the relationship between monumental architecture and intimate human presence creating dynamic scalar play that enriches spatial experience and photographic composition alike. The atmospheric conditions captured in this representation enhance the architecture's evocative power, the blue hour's distinctive lighting creating romantic technical sublime where human engineering achievement rises luminous against gathering night, the internal warm lighting radiating outward through transparent surfaces suggesting warmth, welcome, and institutional vitality, while the external cool atmospheric envelope provides chromatic context that emphasizes the structure's beacon-like presence as vertical marker within the urban or exhibition landscape. The careful orchestration of natural and artificial illumination demonstrates sophisticated understanding of architecture's temporal dimension, how buildings transform across diurnal cycles and seasonal variations, here presented at the optimal moment when internal and external lighting achieve balanced intensity, neither overwhelming the other but creating harmonious interplay that celebrates both technological illumination and natural atmospheric beauty. The compositional choice to include the full moon positioned directly above the tower's apex introduces almost mystical alignment, creating vertical visual connection between earthbound construction and celestial sphere that subtly elevates the design's symbolic resonance beyond purely functional considerations toward more poetic territory where architecture participates in cosmic order and establishes dialogue between terrestrial making and universal patterns. Viewers encountering this pavilion are invited to contemplate how contemporary architecture continues humanity's ancient impulse toward vertical construction and skyward reaching, how observation towers and landmark structures serve communities through practical functions of viewing, gathering, and orientation while simultaneously fulfilling deeper cultural needs for symbols of achievement, progress, and civic identity, and how successful public architecture must balance monumental presence with human accessibility, technological expression with atmospheric sensitivity, structural clarity with experiential richness, raising questions about what qualities enable architecture to transcend purely functional performance and achieve genuine landmark status that resonates across diverse audiences and enduring time.

Design Interview about Octagon Expo Pavilion

Nikola Tesla's remarkable public display of his invention at the 1893 Chicago Colombian Exposition, along with his famous Long Island Tower—representing his goal to connect the world through radio signals—motivated me to create this design as a homage to his commitment to improving the quality of life on planet Earth.

For centuries, the octagon, as a perfect geometric shape, has been employed in the design of public buildings, and the Tesla Tower embodies this architectural style, making the Octagon pavilion surrounding the Tower a fitting option to showcase this form in harmony with the same design philosophy.

I aim to present this design as a unique EXPO pavilion collection to all host EXPO nations globally that are eager to endorse OCTAGON and Nikola Tesla as a global scientific heritage, while also promoting their national inventions that can enhance overall quality of life

I spend around 6 months for preparing and creating the OCTAGON

The inspiration to dedicate part of my architecture to Nikola Tesla arose from my daily visits to the Architectural Faculty in Belgrade, Serbia, where he still resides in front of the building with an open book, encouraging me to discover the best ideas in architecture and, of course, to create something in his honor

This concept design was developed for my Studio and first showcased to SERBIA due to Nikola Tesla's Serbian heritage. Nonetheless, as SERBIA chose to create a pavilion akin to the Moroccan pavilion from DUBAI 2020 for its Serbian National pavilion at EXPO 2027, I will promote this design to other nations hosting EXPOs across the globe. It is also possible to set up this ensemble in the USA at Long Island sites where Tesla constructed a Tower that was dismantled in 1917

An opportunity to showcase the legacy of Nikola Tesla at a global EXPO event

This design draws inspiration from my colleague Stanford White's original tower design from Long Island, as well as the Octagon pavilion that encircles the tower, along with the sci-fi movies and cartoons I've encountered, which have also impacted my work on various space stations

ELON MUSK since he respect Nikola Tesla legacy he might be in situation to develop OCTAGON as one of his HQ

This design distinguishes itself from other concepts similarly to how Nikola Tesla distinguished himself from other scientists during his creative era

The OCTAGON has surfaced in various cultures, but one of the most significant is its link to Ba Gua, which serves as an excellent method to assess the energy field of your surroundings. This Octagon will feature those precious energy fields surrounding the Tesla tower that simply promote his mission regarding the using of energy in their best way

I create pencil drawings, followed by 2D and 3D illustrations, and the post-production, particularly for lighting and materialization, came with tools developed by my excellent colleague Dr. Mohamed Abdel-Shakour and his team at https://mnml.ai/

The idea that with this design Nikola Tesla legacy will be promoted in 21 century

I work with some close associate in my Studio RUDA

The primary focus of this design will be the energy efficiency system in technology

I explored numerous books on Nikola Tesla's life to sense his energy field and conducted research on the symbols and approach in spacecraft design as well

The primary challenge was to link the Tower with the Octagon, which was achieved through the columns designed to resemble lightning strikes, serving as supports for the atrium's glass roof

I have been involved with A Design Award since its initial presence as an online competition. A brilliant mind behind all this is my colleague Dr Onur Cobanli and his doctoral thesis about the best online competition and the rest is history and future of this great competition

Every step in designing of this work was impressive like Nikola Tesla spirit was with me all the time

Always strive to create something beneficial for humanity with your thoughts. Nikola Tesla was not concerned about money, but without individuals willing to invest, humanity would lack many inventions that enhance our quality of life.

Grand Interview about Octagon Expo Pavilion

Given 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.
