Black Box is a minimalist house located in Gyeonggi-do, South Korea, designed by UTAA. The project is located in Pangyo-dong, which began under the plan to create a sustainable urban environment in order to provide urban-space to ensure regional development and space in the city center. The clients were concerned with privacy from the windows, but in order to allow ample natural lighting to enter the home, the architects decided to utilize ribbon windows in order to retain privacy without sacrificing lighting.
