This challenge teaches how to build a container home and learn how to maximize a small footprint by designing a compact yet functional home.
Participants will first follow the provided tutorial to learn the construction method, then personalize their build with their own creativity, decorations, architectural style, and functionality. Just like previous challenges, it serves as the foundation, not the final result. The tutorial can be found here: Container House Tutorial (Special thanks to Mui-yu for sharing the design.)
