Current attitudes towards health dictate that sanitisation of living environments is akin to healthy conditions. However, recent studies show that total erasure of microbial communities may be detrimental to health, removing potentially beneficial bacteria from our vicinity. Microbiosis proposes the microbiome of the built environment as a tool to enhance occupant health through complementary design methodologies, aimed to reintroduce health-promoting microorganisms.
The project is based on leading research within the fields of health, the microbiome, and the built environment, supported by individual data collection, environmental analysis, and material studies. Results were fed into a procedural computational design agenda, with the intention of creating niches for selective health-promoting bacteria to outcompete other, potentially harmful, microorganisms. Robin Hood Estate in London was chosen as an experimental site to apply the microbiome-centric retrofitting approach for creating healthier urban environments. Units were modified regarding airflow, human interaction, and space usage as agents affecting microbial dispersal and transfer from building to occupant.
Swabs and air samples were taken from surfaces based on location, light intensity, and air flow to understand the effects of environmental factors on microbial communities.
Different materials were sterilised, left in air to colonise, then swabbed periodically. Microbial cultures were grown on agar to evaluate community development.
Full library of material iterations developed to augment the growth and survival of selected health-promoting species of bacteria.
Rice and rice husk material samples were inoculated with Bacillus subtilis. These biomaterials allowed persistence for longer than existing built environment materials.
An air-tight microcosm was developed to simulate the effect of air flow and surface geometry on colonisation processes of bacteria within a room.
Perspectives inside the apartment showing bio-receptive materials applied to surfaces and furniture to introduce beneficial bacteria to the built environment.
The geometry is based on the proposed interior cladding of the apartments and used as the physical application of the materials used in this project.
