LOCAL HERITAGE OF THE MODERN MOVEMENT ARCHITECTURE: RE-THINKING HOUSING ESTATES OF THE SECOND HALF OF THE 20^TH CENTURY HERITAGE IN IZMIR, TURKEY AND UPPER SILESIA AGGLOMERATION, POLAND, FROM A CONSERVATION PERSPECTIVE

The modernist “International Style” has evolved uniquely in distinct local contexts. Therefore, discussing and protecting Modern Movement architecture heritage necessitates an approach that harmonises universal principles with local nuances. This study reevaluates the housing legacy of the latter half of the 20^th century in Izmir, Turkey and the Upper Silesian Agglomeration, Poland, as a research and conservation endeavour. These areas, characterised by industrial significance, dense populations and dynamic residential architecture, feature housing estates from the 20^th century, bearing permanent traces of urban layouts. Our goal is to deepen our appreciation for 20^th-century modernist architecture, with a specific focus on these estates. This study uses a qualitative data collection method that focuses on case studies and includes mixed analyses of primary and secondary sources. It stands as a pilot initiative for recognising and evaluating architectural heritage while identifying potential threats to its preservation. The result is to see these structures as heritage repositories, encapsulating comprehensive information at architectural and urban scales.
