The concept of fitness advocated by Wonderfit is different from other fitness concepts, so we abandon the space division required by the ordinary gym in the layout of the space, instead, think more about how to integrate socializing and fitness into your life. A black volume penetrates the building, thus entering the space, and a small opening at the entrance brings in light and guides people inside the building. As the center of the space, the light on the ground connects the two different atmosphere of the fitness area and also guides the vision.
