The question of sustainable architecture is a function of many parameters relating to our tropics, our modes of operation, our cultures. the Karawitz agency is trying to change the paradigm to put these notions into perspective, testing devices and testing itself in regions far from its habits. From cameroon to martinique, the agency has developed projects that respond to specific environments. Each time, the program is interpreted in a vernacular architecture that responds to its environment. The choice of manufacturing techniques and local materials can enable the inhabitants to appropriate their spaces by participating in their construction.
