The Ecosystem of Contrasts: Why the International Building Exhibition 2034 Succeeds as a Union of Berlin and Brandenburg.
International Building Exhibitions—IBA for short—are globally renowned laboratories for the future of designed living spaces. They are not merely showcases for architecture; they are concentrated innovation programs measured against societal values, translating visionary ideas into real urban and landscape projects over many years. With discussions now underway for the fourth regional IBA in 2034—exactly fifty years after the 1987 West Berlin exhibition—it must no longer be confined to the Berlin city limits. A contemporary building exhibition unfolds its full impact as an integrative regional project. The end of the physical division of the country into East and West opens up the opportunity today to define the IBA from the start as an inseparable unit of Berlin and Brandenburg. It is about creating a shared ecosystem of contrasts: the dense, vibrant metropolis and the vast, resource-rich Brandenburg landscape are no longer separate worlds in 2034, but the two heart chambers of the same future region.
A look at the demographic realities shows the momentum that makes this shared path inevitable. Currently, around 3.91 million people live in the federal capital, and the trend is sharply upward. By the IBA year 2034, statisticians—according to current population projections by the Berlin-Brandenburg Statistics Office—forecast continuous growth, steering the city straight toward the historic mark of around 4 million inhabitants. So far, the administration has responded to this enormous growth in the usual way, focusing on acute inner-city housing shortages, closing local vacant lots, or converting old factory courtyards. Yet, the most pressing questions for this future four-million metropolis can no longer be solved within Berlin's city limits alone. With its current population of around 2.55 million and a projected stable increase of about 0.4% by 2034, the state of Brandenburg contributes exactly what is needed to master these future crises: space, regenerative resources, and radical transformation areas. Growth in the Mark region is concentrating almost exclusively on the Berlin periphery, which significantly intensifies the pressure for a shared regional planning approach that is synchronized from the very beginning.
Looking back, the major building exhibitions have always sought answers to the crises of their time. The first exhibition in 1910 fought against the misery of the tenement blocks and laid the foundation for regional traffic planning. The 1957 Interbau showcased rapid, modern reconstruction in the Hansaviertel, and the 1987 IBA developed gentle urban renewal in Kreuzberg with the first ecological experiments. Yet, all these predecessors reached political and geographic limits, as the exhibitions were inevitably confined to inner-city quarters due to the decades-long division of the region. The planned fourth IBA in 2034 offers the historic opportunity to finally overcome this division and revitalize the grown unity of Berlin and Brandenburg, thereby resolving the artificial dividing lines between city and hinterland. It is the logical continuation: it elevates the growth pressure of 1910, the housing demand of 1957, and the ecological awareness of 1987 to an entirely new, joint regional level. International Building Exhibitions have historically been laboratories of density. They showed how modern cities can grow, renovate, or reinvent themselves. Yet, the crises of our time—from climate change and resource scarcity to changing life patterns through digitalization—demand larger systems. When the region launches a new IBA, it faces the classic problems of a growing metropolis: extreme density, land scarcity, and immense pressure on existing infrastructure. The decisive unique selling point of Brandenburg in this structure is not to function merely as an expansion area or a "dormitory town" for Berlin. Brandenburg is the necessary counter-model and the perfect complement at the same time.
Berlin is a consumer metropolis; it consumes energy, food, and above all, building materials. This is where Brandenburg's first great strength lies. The state possesses the land and the agricultural tradition for renewable raw materials. A joint IBA could contribute the living lab for a deepened and contemporary regional economy. From timber construction sourced from Brandenburg's forests to innovative hemp and clay building materials grown directly on local fields, and through to serial manufacturing: Brandenburg can show how regional value chains make the building transition in the metropolis feasible. Paired with Brandenburg's pioneering role in renewable energies and the painful yet instructive experience in dealing with water scarcity, a landscape of resilience emerges—one upon which Berlin is directly dependent.
While Berlin must operate within dense, sensitive existing structures, Brandenburg offers space for experiments on a scale that would be simply unthinkable within Berlin city limits. The state is characterized by massive conversion areas—from old military and industrial sites like Wünsdorf or Luckenwalde to the Lausitz region. The structural change in the former lignite mining district makes the Lausitz one of the most exciting European hotspots for landscape transformation. In the wake of the post-mining era, entirely new water and energy landscapes as well as decentralized, self-sufficient quarters are being created here. An IBA with Brandenburg's participation shows the world how the sustainable living spaces of tomorrow arise from the wounds of the fossil fuel industry.
The future of living and working is no longer determined solely in the center. Through digitalization and "New Work," the necessity of physical presence in the inner city is losing importance. Brandenburg's strength is not a centralized urban sprawl, but its tightly knit network of historic town centers, well-connected medium-sized towns, and lively villages. The renaissance of these medium-sized towns—from Eberswalde and Brandenburg an der Havel to Cottbus—sustainably relieves the metropolis. The Mark's unique feature is the link between high quality of life in the green surroundings and an intelligent digital and physical infrastructure. In rural areas, Brandenburg offers the urgently needed experimental spaces for the mobility transition. As one of the first states worldwide, Germany has paved the legal way for autonomous driving at Level 4—fully automated, driverless vehicles—to become part of everyday life. A joint IBA offers the opportunity to bring this technology to market maturity in Brandenburg's vast landscape, for instance through driverless shuttles that finally connect villages flexibly to railway stations.
That this regional approach is the only sustainable path for modern metropolises is proven by a look at international megacities facing the same planning challenges. The closest functional parallel in the German-speaking world is the duo of Vienna and Lower Austria. There, federal and state governments work closely together in urban-regional management, with the surrounding Lower Austria specifically acting as an ecological raw material supplier and forestry partner for Vienna's building transition. When it comes to the strategic linking of dense urbanity and vast spaces, the French century project "Grand Paris" provides the groundbreaking concept of a lived "symbiosis of contrasts." To relieve the extremely dense Parisian core, the entire surrounding Île-de-France region is being radically networked, with autonomous on-demand shuttles being tested intensively in rural zones to flexibly connect villages to regional express train stations. Finally, the Canadian Greater Toronto Area with its "Greater Golden Horseshoe" shows how to prevent the uncontrolled sprawling of a metropolis and protect the rural space. A monumental, planned greenbelt ensures there that the spreading into meadows is prevented and that instead, the surrounding historic medium-sized towns are strengthened as independent, high-tech, and cultural hubs.
Berlin and Brandenburg in Union – The Symbiosis of Contrasts. Under the joint leadership of Berlin and Brandenburg, the IBA 2034 should be organized to function as a living ecosystem of contrasts. Berlin brings density, the investment market, and the pressure for innovation. Brandenburg contributes its vast space, raw materials, and the bold experience with large-scale structural change. Only in this symbiosis does a building exhibition become a forward-looking regional exhibition. Following the insight: "City and country are not opposites, but two poles of an indivisible reality of life." Entirely in the spirit of the Charta of Athens, living, working, and nature are transferred here into a single, large regional structure. What Paris, Vienna, or Toronto are testing in partial areas today can make the Mark-Berlin living lab a global reference in 2034: a functioning, crisis-proof symbiosis of a dense metropolis and a resilient hinterland.

Paths to Insight Between Stardust and the Foundation Pit
"The only constant in life is change," taught Heraclitus. We navigate landscapes that transcend mere physical space; they are resonance chambers of our existence. Each sensory impression, every image we capture, serves as an orientation point in a world that recomposes itself in every moment. We measure the unfathomable by imbuing the energy that surrounds us daily with structure—a perennial search for stability amidst the kinetics of duration.
This field of tension is best illustrated by two opposing poles: On one side stands the perspective of Carl Sagan (1934–1996), who, in his seminal work "Cosmos," envisions the universe as an architecture of immanent, physical order. Conversely, the Russian writer Andrei Platonov (1899–1951) challenges us: in his work "The Foundation Pit" (Kotlovan), it is the existentially charged weight of matter that interrogates the world, while his novel "Happy Moscow" (Schastlivaya Moskva) portrays the arduous construction of the subway as human agony and a profound, painful anchoring in the underground. Between these poles, architecture unfolds as a necessary process: it is a continuous becoming that does not merely grasp space formally, but functions as a built manifestation—a direct formation of our existence, in which life is understood as a permanent construction.
Here, the encounter takes place between cosmic order—a state of constant contingency and fragile constellation, in which weight masquerades as a condition of suspension—and the existential weight of Platonov's world. The latter is permeated by suffering, fleeting joy, and that paralyzing inescapability which remains the only certainty. My works are created through the pictorial layering of multiple moments in time — often with a density of image layers in the high double-digit range — a structure emerges that redefines space as a highly complex, elastic event. The work does not document a conventional perspective, but presents a processual, formative act of transformation on an image-edifice. By architecturally constructing this condensation, I open a resonance chamber in which insight acts as a shared experience.
In the layering of these photographic works, architectural fixpoints function to stabilize the visual narrative flow and offer the gaze a foothold. Precisely here gapes the unnamed intermediate space—an element of indeterminacy that only defines itself through perception. It is a threshold space where cosmic perspective, statics of construction, and the dynamics of city life collide.
This space demands engagement. It is not intended to be inhabited. To grasp it in its depth requires an attitude that transcends mere analysis: a form of phenomenological reduction, a state of conscious openness in which all conceptual preconceptions are suspended. In this mode of perception, a dissolution of the ego from its fixed identity takes place, akin to what Friedrich Schiller described as a merging with matter.
It is not a blind affect, but a highly concentrated receptivity that allows the urban fabric and the cosmic reference to be experienced as a unity. My images are created directly on site, in a conscious engagement with the environment. Here, the individual human being enters the image as a vessel for those fleeting impulses in which the statics of matter reveal themselves as a lived experience.
Naturally, this process of deep perception is no guarantee of enlightenment. Mostly, it occurs in the most profane of moments: while waiting at a traffic light whose timing is as relentless as the cosmic order itself, or in the dense crush of the subway, where one suddenly realizes that the "multiple coordinate system" of the world consists of nothing but a large number of people all trying to remember where they left their bags. Here, in the absurdity of the everyday, the circle closes—for it is precisely in this moment of amusement that realization becomes the most human of impulses.
Insight does not unfold linearly here; it is a charging interplay, a constant layering and reflection, in which the retardant moment—the hesitation before final determination—serves as a necessary corrective. Insight thus becomes a cumulative movement: a layering in which every new understanding rests upon the previous one, while simultaneously casting it into a new, elastic light. Only in this openness can the multiple coordinate system transition from a theoretical construct into a living intuition. In this state of highly intense consciousness, the actual encounter of forces unfolds.
When the systematic engagement with Sagan's physical order meets the existential friction of Platonov's world—the anthropological shock, the sensory experience, and the fleeting movements of the soul—that spark arises in which, through analytical precision, insight can emerge from condensed perception. This movement unfolds in three modalities:
This practice transforms the photographic image into an optical installation. While artists like Tomás Saraceno or Gordon Matta-Clark thematize the relationship between human, architecture, and cosmos through spatial interventions, I perform this act through a dynamic architecture of the gaze. My images are a constructive process: I reassemble the space of exposure from different points in time in order to re-map it as a complex constellation grown in layers.
We do not map the result; we visualize the impact. In this undefined area, in this threshold space of action, experience is composed of sensory reflection, architectural process, philosophical inquiry, and the vast, infinite gaze upon the cosmos. Why, then, do we measure space? Measuring is far more than an analytical act; it is a fundamental act of unfolding. In a tradition that defines survival through holding on, remembrance through naming, and understanding through perpetual questioning, my dynamic cartography becomes an existential expression of life. It is an act of bearing witness to a fragmented world—an attempt not to mend its fractures, but to anchor oneself within them through an active, sustained engagement.
My pictorial composition serves as the catalyst for the constitution of the landscape of essence: It is no longer an external depiction, but the result of that layering in which architecture, time, and human experience merge into a unity. At this moment, when cartography reaches its limits, the image takes form anew as a constructive act of realization: truth emerges as a contingent construction. It is here that the essence of the image reveals itself as an open resonance chamber for existence.

"Art does not reproduce the visible, but makes visible." – Paul Klee
My artistic practice operates at the intersection of photography, perception and movement. In the tradition of Lyonel Feininger (1871–1956, NY), I understand architecture not as a static mass, but as a pulsating structure. Where Feininger broke the world down into crystalline, transparent planes, I use the camera directly to rearrange urban structures. Being on the move is the guiding principle for these multiple-exposure photographs: transition rather than arrival; instead of loose sequences of landmarks, the path stands as a project of positioning.
Layering forms the core of my work. Through the technique of multiple exposure, photographic works emerge that go beyond the documentary image. It is an "urban archaeology" of the moment:
Like a geological formation, each photograph tells its own story of a different perspective, a different incidence of light, a different movement within the space.
My experience in acting flows into my photography as a rhythmic element. I read urban spaces like the score of a role. Here, the work meets the musicality of every sequence of movement, of every emotional shift – a quality that was also characteristic of Feininger's prismism.
Places thus become scenes with their own tension and inner dynamism. This visual musicality makes it possible to recognize situations in fractions of a second and to bring them to a climax like a fugue. The result is not a static state, but a fluid process of perception – a way of seeing that follows the rhythm of the human eye as it glides searchingly over architectural edges.
"Everything flows, nothing remains." – Heraclitus
