The subject of this research paper is the architectural conservation and reintegration of historic buildings or residential areas in the modern urban fabric. Specifically, the study discusses the different approaches that aim to restore and preserve buildings and residential ensembles of the past. These methods over time acquire contemporary relevance, as more buildings are in need of restoration. The main question that arises is which structures is required to be preserved and under what conditions. In order to analyze the issue of restoration and integration of new uses, certain axes of study were placed. In an attempt to answer the main question we examine the new conceptual frame that is formed nowadays over conservation. An important factor is the green adaptive reuse, which aims to incorporate bioclimatic design and new technology in restorations. Furthermore, the matter of reversibility arises- that is to say, whether it is possible for future generations to restore a building to a previous phase and host new uses.
The architectural projects of the past are traces of the history and culture of each country. Over time they are abandoned and degraded due to natural disasters, anthropogenic causes, but primarily because they cease to be active components of the urban fabric and meet the needs of the society. At the same time, maintaining and revitalizing residential settlements, according to the needs of the new reality, is of great importance.
The historic restoration with elements of mimicry and the more flexible restoration approach that involves modifications and modern additions, using new distinct materials, define the frame around restoration from the 19th century to the present. Mild interventions, which do not degrade the materiality of the shell, but highlight its historical identity, tend to be followed to a greater extent.
