F.I.T. House (Flexible, Intelligent, Transformable House) is an architecture system designed to simplify the process of construction by designing a single shape panel. These panels join together like a puzzle and they connect to form a sturdy structure without the use of any metal fixings. By replicating a single panel, the structure comes together and can be expanded in size by adding more panels. Because the size can be adjusted, this system can quickly and flexibly propose the optimal plan to construct for the needs of disaster areas. Such examples include simple housing, community centers, and temporary medical facilities.
