What is abandoned? Why do they exist and how can they be used? Both the examples of Volos and Athens, note a large stock of abandoned buildings, reminding us of the need for feasible and applicable practices for their reusage. Along with a methodology for their utilization and recording, this dissertation presents a DIY construction of a wooden loft (1: 1), during a co-hab in a house of Volos. Lastly, with reference to the abandoned in Athens and specifically in the area of Metaxourgeio, a design proposal is presented for the reuse of a building, in a bakery-cafe.
