Parasitic Dilemma

Designing Multispecies Habitats for Symbiosis and Coexistence in the Built Environment


Introduction
Urbanization and industrial expansion accelerate pollution, climate change, and biodiversity loss. This thesis reimagines architecture as a dynamic, living system that fosters biodiversity, promotes multispecies coexistence—from microorganisms to humans—and mitigates environmental damage.

Methodology
The research follows a mixed-method approach, combining literature review, spatial and environmental analysis, and computational experiments. An actor-based spatial strategy maps human and non-human interactions, informing the design process.

The project relies on three key concepts:

I. Bioreceptivity
Bioreceptivity refers to a material’s ability to support living organisms (Guillitte, 1995). It enables microbial, fungal, and plant colonization, creating habitats for insects, birds, and other species. Both intrinsic factors (surface texture, porosity, material composition) and extrinsic factors (temperature, humidity, sunlight exposure) influence its effectiveness (Ortega-Morales et al., 2021).

II. Landscape Ecology
Urban environments, often seen as biological deserts, can be designed to support biodiversity. The Patch-Corridor-Matrix Model (Forman, 1995) enhances ecological connectivity, guiding urban planning to promote species movement and ecosystem resilience.

III. Multispecies Design
This approach challenges human-centered architecture by introducing a method for designing multispecies habitats and understanding the complex relationships between different species within the built environment.

The chosen site is an abandoned industrial hangar in the Port of Belgrade, one of Europe’s most polluted cities, struggling with air and water contamination. This location serves as a testing ground for ecological restoration.

The project accommodates both human and non-human users:
– Humans: Occupy the Research Hub, where environmental conditions are monitored.
– Endangered species (Ferruginous Duck, Eurasian Beaver, European Ground Squirrel): Reside in Protected Core Zones, shielded from predators.
– Local species (Red Fox, Roe Deer): Roam Open Ecological Zones, connected togreen corridors for migration.
– Moss & Plants (Tortula muralis): Colonize bioreceptive geopolymer surfaces,enhancing biodiversity.

The project balances biodiversity conservation with ecological integration:
– Protected Core Zones safeguard vulnerable species.
– Open Ecological Zones encourage natural interactions.
– Urban Corridors connect fragmented green spaces, ensuring ecological flow.

To promote moss colonization, the structure’s form creates self-shaded, humid microclimates. Ladybug analysis optimizes the geometry, reducing solar exposure to enhance bioreceptivity. Karamba and Galapagos simulations optimize the structure by reducing roof displacement and improving stability through strategic support placement. The structure is shaped using an inflatable balloon mold, reinforced with steel and bioreceptive geopolymer—a sustainable material with high strength and microbial colonization potential.
