Architecture firm Marutau Arqui has completed the Octa House, which is nestled on Shikoku Island in Japan. It is defined by a multi-faceted red facade and it is made up of two overlapping octagons. The design project was created by the design team for a local family with three children.
The plot is surrounded by high-rise buildings and is built on what was once a car parking lot. The founder of Marutau Arqui, Yoko Okegawa explained that bright and vibrant hues were chosen to bring "warmth, softness, and identity" to the home. "We proposed a brick color that is familiar to people in Japan and blends in well with the streetscape, yet does not blend in with its surroundings and expresses a strong sense of presence."
