An artist's depiction of the city of Venice after the implementation of the metabolic materials of Rachel Armstrong. The limestone formations protect the buildings from the sea and new sea life can utilize the architectural formations bringing a new attraction to the city which is sustainable and natural.
Another exciting bit of research involving living, or in this case, semi-living protocells and architecture. Dr. Rachel Armstrong, from the Bartlett School of Architecture, discussed her ideas for buildings that not only repair themselves, but signal a departure from traditional architecture. Her ideas call for architecture that merges with the environment through materials that are alive and become part of the ecological systems in the surroundings. In this way the buildings can be sustainable, beneficial to the inhabitants of cities, and produce opportunities for new encounters with life.
