The integration of biotechnology into architecture is opening a new direction for the construction sector: buildings capable of generating construction materials. The concept is based on the use of biological systems integrated into building structures—especially façades—that can produce biomaterials or mineral compounds useful for construction.

One of the most studied mechanisms is biomineralization, a process through which microorganisms transform chemical compounds into solid minerals. Under certain conditions, bacteria can produce calcium carbonate, a material similar to the mineral components used in cement and concrete. Recent research is exploring the possibility of integrating these microorganisms into controlled biological structures installed in façades or architectural panels.

In these systems, microorganisms are cultivated in bioreactors integrated into the building, where they use light, water and nutrients to generate mineral compounds. The resulting materials can be collected and used to produce construction elements or to repair existing structures.

Another direction of development is represented by biological façades with microalgae, systems capable of producing biomass that can be used in industrial processes. These installations function simultaneously as architectural elements, carbon capture systems and biological production units.

From an energy and climate perspective, these technologies are of major interest. The construction sector is responsible for approximately 40% of global energy consumption and a significant share of carbon emissions, and the integration of biological processes could contribute to reducing environmental impact.

At present, most projects remain in experimental or pilot stages, yet the rapid evolution of research in biotechnology and architecture suggests that buildings of the future may function not only as habitable spaces, but also as productive platforms capable of generating materials and resources directly within the urban environment.
