When Korean architect Byoung-soo Cho set out to design his dream house in Seoul, he found the project unexpectedly challenging at first. Eventually Cho settled on the idea of arranging four two-story, rectangular concrete boxes around a central courtyard, giving the home a layout resembling a cardboard box with all its flaps open. Because the boxes only overlap partially, each box can have windows on all sides, allowing fresh air and sunshine to flood inside.
