The Phi Books have used the house as a metaphor for interdisciplinary collaboration by using narrative, making and performance to explore how borders, walls and doors facilitate collaboration. This has lead to the production of books and interactive material produced by the authors and the participants, which are both fictional and imaginative while also being methodologically reflective. We would like to present the development of the Phi Books Project, showing its different stages, from the initial formulation of algorithmic fictions to technologically mediated and embodied systems for collaboration.
