Heres a school design I made for a design exchange contest back in the day. The building uses sustainable building materials such as recycled steel and recycled iso shipping containers to create the form of the building. The exterior cladding is made from the corrugated siding of the shipping containers. The colored squares on the facade indicate the outline of each shipping container used on the second floor. Each iso shipping container must be checked for any inadequacies before being installed on the steel frame that holds the containers in place.
