Development of nano and biotechnologies encouraged us to develop a concept of automated building, which will significantly reduce the many negative impacts of traditional construction on the environment. The paper describes the concept of Nano- to meter-scale building, a new way of building, which unfolds from the nano into the meter range. The concept is based on bionanorobots, producing building materials using carbon, contained in CO2 from the air. Criteria and requirements regarding nano and biotechnology are defined and compared to the current research in the field of biotechnology, nanorobotics and production of carbon nanotubes. The paper is further presenting a new building technology that will enable control and monitoring of construction at nano level, as well as requirements regarding design methods and tools, for the digital model of the building will become the only input to the automated nano-building process. The paper concludes with a plan of further research and development.
