If the essence of space is to represent the appearance of the dweller, then our purpose is to let the inner world of the dweller to be established in the actual space. Stage is a theatrical space, linking the classical opera style with walnut material, and using strong contrasting colors to make each space in the field have its own attributes. The semi-open compartment relationship increases the flexibility of the space in the future. The arch with red copper wall divides the living room, the leisure area and the dining room, but it is also the visual key to connect the three spaces. The red copper will oxidize with the passage of time, which makes time meaningful to the space and is a clever makeup. It can make the space classic and eye-catching, and It can also produce a unique charm with the time goes by.
