Today, the need for designing appropriate housing spaces becomes a fundamental aspect of architecture. To ensure the operation of these spaces and their sustainability, an architectural approach is needed. Transformable architecture, which encompasses designs that can be transformed according to different functions and used for many purposes, is the architectural approach for enhancing housing spaces that might adapt with the ongoing process of changing needs. Hence, architects are challenged to create innovative spaces to satisfy the needs of all users. Therefore, the main aim of this research is to explore the role of transformable architecture in redefining contemporary housing spaces in respect to the various needs of users in different psychological, environmental and economic contexts. To achieve this aim, this research employs a scientific methodology starting by reviewing the literature that provides knowledge about transformable architecture and its implementation in contemporary housing spaces; then analyzing four selected international case studies: Suitcase house in China, Safe house in Poland, Living Room House in Germany, and Sharifi-ha House in Iran and comparing them. These facts serve as the foundation for the authors' argument that transformable architecture is a good stand point for suitable design strategies to improve the functionality of housing spaces and to respond to diverse users' needs. A set of recommendations regarding the application of this architectural approach are drawn as guidelines in designing contemporary housing spaces.
