Through a series of competitions, speculative commissions, and built work, FOA's first monograph is structured to reflect the development of their specific attitude and as a compendium of the technical arsenal that they use to within their practice. With the spirit of scientific classification, the genesis of an architectural project is identified within a series of phylum, actualized and simultaneously virtualized, in their specific application to the unique conditions of a project's location. Phylogenesis also includes a collection of texts from several critics who investigate related topics that touch upon different aspects of FOA's discourse.
