The original site is a narrow and closed semi-underground space. Our proposal is "let in light and nature" To break the closedness of the space, we removed as many walls as possible so that light and scenery can enter inside. By using Lightweight perforated metal mesh as the main material of the space, through the combination of gray metal plates, white texture paint, and gray carpet, as well as figure walk past forming interactive virtual shadows, which increase the flexibility of the space and create the hierarchy and dimension of space. From darkness to light, space is reborn.
