Sustainable living is basically being able to construct the balance of protecting and using natural resources. In this way, the heritage value transferred to future generations is formed by the interaction of people and the environment. This is also very important for "architecture", which expresses sustainability and is an important tool. In addition to the continuity of sustainable architecture and cultural heritage, it is possible to create economic resources and detect sociological data. Local architecture, which bridges the past and the present and best reveals the relationship of people with each other and their environment, has a place in many parts of the world with its rich diversity. Local architecture has an active place in contemporary society with its cultural, socio-economic and concrete identity values. These structures are protected by various strategies and methods and transferred to future generations. One of these methods is adaptive re-use. Within the scope of adaptive re-use, the study examined the principles of sustainability through eight second-degree registered Islamkoy residences in the Demirel Complex of Islamkoy village in Atabey district of Isparta province in Turkey. Thus, by evaluating three basic principles, environmental, economic and social, in terms of the continuity of local architecture with the sub-parameters determined, it was aimed to reveal the benefits and damages caused by the complex to the settlement in terms of sustainability. In this way, the change and transformation created by re-functioning with the renewal of building materials and typology was examined.
