UF01.
Aquaponic Rooftop Farm, Basel, Switzerland.

UF01 (2011) is the first realized aquaponic rooftop greenhouse in Europe. The project intervenes on one of the most extensive yet underused spatial reserves within contemporary cities: large, flat industrial rooftops. Detached from everyday use and largely invisible, these surfaces remain outside the urban imagination despite their structural capacity and scale.

UF01 relocates food production from the ground to the rooftop, introducing an aquaponic farming system conceived not as a technical add-on, but as an architectural and spatial organization operating at an urban scale.

The intervention is structured through a clear act of displacement. Elements typically associated with ground-based production and logistics — prefabricated greenhouses and industrial containers — are lifted onto the rooftop and recomposed as a coherent architectural system. Food production is separated from its conventional territorial setting and repositioned within the industrial fabric of the city.

Aquaponics defines the internal logic of the project. The reciprocal relationship between fish, plants, water circulation, and spatial configuration organizes both technical performance and architectural layout. Production is not hidden behind the building or relegated to infrastructure, but becomes the structuring principle of space itself.

The system follows a modular and generic architectural approach. A greenhouse accommodates the aquaponic cycle, while container units host storage, technical infrastructure, and administrative functions. These elements can be arranged in multiple configurations according to site-specific conditions, allowing adaptation without loss of systemic coherence.

By assembling productive, industrial, and architectural components on the rooftop, UF01 establishes a concrete condition in which unused urban surfaces enter into operation. The project does not propose an abstract model, but demonstrates the buildability of a new spatial relation between city, production, and architecture.

As a built prototype, UF01 extends a research trajectory later articulated within Epistemic Design: spatial reorganization does not merely symbolize change, but materially reconfigures ecological, economic, and urban systems.

Displace — UF01 operates through a physical and typological shift, relocating agricultural and industrial components from the ground to the rooftop and redefining buildings as active productive surfaces.

Expose — The project exposes the latent infrastructural capacity of industrial rooftops, revealing them as structurally and spatially capable of hosting urban production rather than remaining inert surfaces.

Mediate — UF01 mediates between architecture, ecological cycles, and urban industry by integrating aquaponic systems into a coherent spatial framework that holds together vision and technical realization.

Activate — The project activates unused industrial rooftops through the assembly of greenhouses, containers, and infrastructural systems into an operative architectural condition.

Through construction rather than speculation, UF01 demonstrates that urban production can be structurally embedded within the city’s existing fabric.
