Concrete is a very important construction material in Taiwan, it is strong and stable, but also too cumbersome and cold. We hope to reestablish the value of concrete as not just a lifeless material, but through interacting with light and shadow, time and space, it can become the catalyst for vitality and life in a home. We used semitransparent eco friendly concrete, and engraved upon it early Taiwanese window patterns. Thus forming "luminous stones" As sunlight passes through it, warm life and memories shall pour into your homes and lives.
