As the visitor center of John Jay Heritage Center and another entrance of John Jay estate, the design shows the labor distribution status in history and its corresponding space in the visitor center abstractly. Through the replacement and turnover of two different materials in the section— material belonging to the interior (plants) and material belonging to the exterior (lath)—the labor and service places of the tourist center are extended into the exhibition places. This shows the history of the emancipation of slaves by revealing and breaking the original history of spatial hierarchy, and the two sides of John Jay’s history. The space of the building is linear. Every space that tourists pass through is affected by the room serving the space. The exhibition content is closely related to this influence. Tourists can see or feel the workers behind the scenes from the cracks, openings, and extended structures, such as the historical exhibition hall and archives, the hall and office, the dining room and the kitchen, etc. Materials and structure are closely linked and complement each other. Therefore, the workers in the tourist center are not only workers. Their working state and place becomes a part of the exhibition, making the building itself express the most important part of John Jay’s history—the change of labor structure and its spatial state.
