There are many emergency situations on earth nowadays which are caused by various reasons like wars, floods, storms, and earthquakes as has been lived in the eastern part of Türkiye on the 6th of February, 2023, in which many shelters become necessary to be built as quickly as possible. But in this kind of places, after the necessity disappears, what happens to those shelters is a big and important question of efficient use of resources, energy and money, besides getting many of these shelters ready to be used in a very short time. Therefore, the aim of this study is to examine the accommodation problem of emergency shelters from the viewpoint of sustainability, and to propose a method to solve this accommodation problem which comes from a vernacular model of building use in Türkiye, which will lead us to create sustainable architecture products of shelters that will not waste our resources, energy and money. In order to do this, sustainability and Village Room terms are described, six case studies are examined and from this examination “City Rooms Model” is proposed. This model would be used in anywhere in the world and after the residents move out, these buildings would still be being used efficiently. Therefore, the proposed model in this study would lead the world to a circular economy and a more sustainable future providing better accommodation possibility and opportunity. With the use of this model, sustainable architecture, sustainable world and sustainable future would be achieved.
