Using the biomimicry method and inspired by the process of phagocytosis (which is in an organism's immune system, the major mechanism to remove pathogens when a macrophage ingests a pathogenic microorganism),PHA center resolves the site's constraint of three existing pine trees and creates an unusual fluid volume contrasted with it's rational surrounding.In this manner the project presented sustainable criteria and made a break in a street full of long buildings while providing the public with a shaded small public garden.
