The study of the diploma thesis entitled " Redefining the shells-Conversion of an industrial building into a homeless accommodation center" by students Dionysia Astli and Jovahnna – Ioanna Giannopoulou and supervising professor Mr. Fabiano Micocci focuses on one of the most sensitive and important problems of our time – the homelessness. It is not an unprecedented phenomenon of today's time, on the contrary, it is a timeless situation that was observed in various places and periods of time, from ancient times until today. Unfortunately, society is unable to find a solution to the problem. As a result, it swells continuously. In Greece, the largest number of homeless people are found mainly in the large urban centers of the country, such as Athens, Thessaloniki and Volos, and today, through surveys that have been carried out, more than 1600 people have been recorded living on the streets, of which most are gathered in the capital.

 The reasons that lead to homelessness can be multidimensional and different from person to person. For this reason, it is crucial to develop personalized models that treat each person as unique – an understanding that is also necessary for the way we approach the effects of homelessness.

 The idea of the thesis proposes the creation of a new structure for the temporary accommodation of homeless people, which will provide them with the appropriate support so that they can be helped, work and gradually become fully independent and integrate smoothly into the wider society.

 For the creation of the new multi-purpose building, the former industrial building specifically in the area of Nea Ionia, where it operated as a textile factory, was used. Moreover, the park in front of the building was redesigned in order to raise awareness and awaken ecological consciousness and create agricultural jobs, so that the guests can work and at the same time contribute to the structure.

 The guests of the center will work in the pergolas of the program in which they will grow vegetables, fruits and herbs and will have the possibility of selling them in the public market that will be set up in the square of the complex.
