Architecture of Biologically Grown Buildings

Despite the current challenges of climate change and overuse of natural resources, with buildings contributing to 30% of global carbon dioxide emissions, buildings are still designed or retrofitted using old and inefficient processes in a “business as usual” way. Typically, several candidate designs are created by an architect, and the most favourable design is put forward for final development. This leads to a minimum exploration of the vast space of design possibilities, frequently working against the climate and achieving sub-optimum performance.
But can we imagine a world in which building designs are grown into ultimate configurations from design embryos, like nature grows biological organisms, exploring the design space gradually and thoroughly? How can we replicate the processes from developmental biology, working with the climate, minimising the environmental impact, and completely changing the culture of the current design theory and practice?
