This interesting apartment is located in Kaohsiung city, Taiwan, owned by a 30-year-old engineer who want to have a home with natural cement-based environment for him to relax after long busy work. Combining with travelling idea, suitcase board is used as storage as well as decoration in the living room. To have more space, the metal mini bar is the choice for dining. Foldable glass door is used to separate living room and study room to have more natural light. Steel bars were applied to shelving to avoid the heaviness of shelf in study room. Quite a unique design.
