Oval Shaped Tire Classrooms

The primary building structure consists of walls made of packed tires. The walls follow the shape of a circle with a 14’ internal diameter creating a geometrically stable shape where no buttressing is needed.

Tires are filled with the earth taken out during the excavation stage, and non-biodegradable waste. The tires are stacked in a running-bond pattern to maximize interlocking between courses. Additionally, horizontal rebars are laid between two courses about halfway up the wall in order to stiffen it against lateral forces during the construction stage.
