This minimal concrete house was designed by Japanese architect Tsubasa Iwahashi. The concept was to connect the resident family inside the house while occupying different rooms. Family members are connected to each other, but at the same time house gives them a moderate sense of privacy. They can spend time together or alone. House is located in the suburbs of Hyōgo Prefecture. It contains two-storeys, however the space inside is arranged across multiple floors. In order to create a hidden storage area and a loft room, the second floor is divided into two levels. There are total three staircases in the house. One of them is a traditional wooden staircase that leads from the reception to piano room. On the ground floor there’s a living, dining and kitchen areas. Sliding glass doors extend the living room to a wooden terrace. Wooden floors and ceiling beams can be found in every room.
