In 1962, architect Buckminster Fuller envisioned a floating city that would free humanity from its dependence on Earth. The hypothetical project consisted of massive, airborne geodesic spheres that would naturally levitate on warm, sun-heated air, anchored to mountain peaks. Designed to house thousands of people, Fuller's Cloud Nine structures aimed to ease land ownership politics, address housing shortages, and help preserve nature.
More than half a century later, we remain far from realizing Fuller's vision. Creating a truly floating structure on the Earth's surface remains, for now, an unattainable ideal. While structural supports remain a necessity, we manipulate their position, intensity, and quantity, performing architectural acrobatics to at least approximate the idea of defying gravity—a desire that has long fascinated humanity.
The myth of Icarus and Daedalus, flying carpets, and castles in the sky are just a few of the dreams that reflect this fascination, permeating various aspects of society and human existence. In practical terms, however, gravity is challenged in different ways. In painting, Kazimir Malevich—a self-declared inspiration for Zaha Hadid—depicted geometric figures floating on white backgrounds in his weightless compositions. He even went so far as to exhibit his paintings by hanging them in a way that made them appear to float on the wall.

In industrial design, Marcel Breuer used tubular steel in 1926 to create a chair in which the user was suspended over empty space rather than firmly supported by four sturdy legs. In cinema, Alfred Hitchcock's 1958 film Vertigo explores, albeit from a different perspective, the concept of gravity and the persistent fear of falling through space and time. Yet it is in architecture that the quest to defy gravity becomes most evident.
Since the completion of the Pyramids, architecture has become increasingly light, and in the twentieth century, this process will accelerate, making it even lighter. — Bernard Tschumi
This lightness stems from several factors, beginning with utilitarianism. Some researchers argue that stilt houses, built over water or ground, are one of the world's oldest construction methods—and perhaps the earliest in the pursuit of lightness. Dating back to the Neolithic and Bronze Ages, they survive to this day, primarily in riverine communities, coastal regions, or floodplains. This typology has been crucial to the emergence and survival of the concept of floating structures, initially developed for practical safety reasons.
Moving from utility to spiritual milestones, Gothic cathedrals, for instance, sought to transcend gravity. This time, they did so not for physical comfort, but for spiritual elevation. Their pointed arches, combined with ribbed vaults and a remarkable capacity to manipulate light—whether through stained glass or strategic openings, as seen in the dome of the Florence Cathedral designed by Brunelleschi—made these structures appear to reach for the heavens.
In their lightness, achieved through bold structural and technical feats, these cathedrals were configured as spaces designed to elevate the spiritual experience, directing the gaze—and the soul—upward. This subtlety was interpreted as an attempt to transcend the weight of the physical body, acting almost as a denial of our own finitude.
This grandiosity, while allowing the spirit to soar, also evoked a sense of oppression—of insignificance in the face of such scale. These opposing yet complementary feelings converged toward a shared sense of subordination. A similar sensation manifests in the manipulation of architectural lightness within an entirely different context: Modernism.
Soviet Modernist civic structures, for instance, leveraged advancements in construction techniques—now utilizing steel and concrete—to create massive spans in structures that appeared to float. In this case, lightness represented power and technological prowess (nearly) overcoming gravity. Although the concept of pilotis and the free plan emerged from the idea of freeing up the ground level to allow the continuity of the natural landscape or urban flow, structural compositions allowed for diverse applications and interpretations, such as the Druzhba Sanatorium in Crimea.
Illustrating the different perceptions created by the same construction technique, Frank Lloyd Wright's classic Fallingwater, for example, features a striking interplay of volumes cantilevered over nature. It made history not by imposing a political ideology, but through its symbiosis with the natural environment. Yet, does defying gravity by placing the house directly over the waterfall, rather than in front of or around it, not also suggest a sense of superiority and dominion over nature?
Through precise engineering that borders on the impossible, the untrained eye is captivated by a structural illusion that appears simple, but is actually rooted in meticulous calculations of anchoring, counterweights, and spans. It is precisely within this extreme "simplicity" that our fascination lies.
This simplicity has been increasingly challenged over the years, making the pursuit of lightness more pervasive and extreme. Today's architecture, freed from canonical constraints and stylistic restrictions, has fostered the conditions for independent creative expression. The Blur Building by the American duo Diller + Scofidio for Expo 2002 in Switzerland is a prime example.
Its architectural performance is realized by spraying a cloud of water vapor into the air through nozzles distributed across the pavilion's entire steel framework. Here, the lightness of architecture is explored to its fullest potential, as the liquid (or airborne) materiality of the architectural performance lasts for only a few seconds, constantly renewing itself.
In doing so, the Blur Building breaks with one of the fundamental pillars of architecture—the very idea of permanence. Vitruvius's centuries-old triad of firmitas, utilitas, and venustas is called into question, as the pavilion's architecture does not depend on them to assert itself as an artwork—one that is almost immaterial. The very definition of architectural space is challenged because the work is perceived and experienced less as a material enclosing surface and more as an architectural event inviting an immersive, poetic, and profound experience. Similar sensations are offered by Junya Ishigami + Associates' Zaishui Art Museum, albeit in a more "material" form.
While acknowledging that it is impossible to cover every connection between the concept of lightness in architecture and the sensations it evokes, this brief historical overview has sought, above all, to investigate the fascination with defying gravity that runs through architectural history.
The opening question of why we want to float in the first place could thus yield several answers: to survive, to project power, for pure delight, or to question current architectural canons—as with the Blur Building—as well as what architecture could become, as with Fuller's Cloud Nine.
Yet, regardless of the outcome, the pursuit of lightness seems intrinsic to the human urge to challenge ourselves—to reach for the impossible, to become capable of dissolving tons of matter with a single gesture. It is architecture testing its own limits within this contradiction—not always beautiful, but at times strange and unsettling—revealing, as Marshall Berman famously put it, that "all that is solid melts into air."
