The subject of this thesis is the concept of underground dwelling, as a cryptic and invisible act of habitation in theory, and also in action, in matters of creating and taking advantage of invisible space. Under these two perspectives, the person of a rag collector appears to be the creator of an underground habitation complex, consisting of several units that leach on the underground maintenance shafts of the rain water collection pipe system of Volos.

  This underground dwelling system in which the Collector habitats, is to be revealed and documented as an archeological find by another fictional character, the Investigator. The thesis presents the drafting, documentation and study of the dwelling as executed by the Investigator, who becomes obsessed by his research.

 The storage and organization practices as well as the compositional attributes of a collector are presented through this fictional human dipole, and in the end, the Investigator’s research on the Collector’s hoarding behavior becomes an obsession on collecting information instead of objects.
