Space design of showroom and live hall for the house builder. The main space use is as a reception and salon. We tried "Visualization of sound" so that we can feel the sound even in normal times when we are not hosting live performances. The gold lattice that sticks along the void space spreads dynamically, as though shouting with a megaphone, and the balance of black and gold changes depending on the viewing angle as if playing the melody. Families often visit this place. I wanted to give a visually pleasant stimulation, not just sound.
