This project revolves around mereological parts’ condition. It defines the house as a condition among multiple architectural parts rather than one defined whole. First, the architectural parts were defined as modules, and then, multiple aggregations were created. Each aggregation was studied vis-a-vis the notion of living. The conceptual approach of this project studies the expansion of systems under mereological condition, systems of closed spaces, semi-enclosed spaces and voids. Therefore, it moves from a wall, to a part, to groups of parts. In such architectural systems, all the parts are ontologically flat, meaning that chronology in terms of designing and making is rather replaced by discrete parts.
