Manufacturing/Building Method

Shipping containers are mass-produced for the transportation of goods. The structural capability, modularity, transportability, and interior space capacity of shipping containers are advantageous for their application in this type of solution. The site preparation consisted of the construction of a concrete platform and steps to adapt the classroom to the existing site and create outdoor space for the children. The platform is also the foundation for the shipping container that was transported and installed using a crane. To protect the shipping container from direct sunlight, designers added a roof composed of a steel structure and corrugated metal panels.
