The correct hint is intuitively felt from the traditional courtyard houses in Beijing. The architectural concept is a horizontal and vertical layering of private and public spaces, guiding paths and views, encouraging visitors to explore every space and discover the moments in between. The external treatment unifies the different interiors into a single shielding box, binds the different openings together, and provides a range of visual porosity relative to the internal procedures through different blind densities. With the gradual change of materials and the continuous fluctuation of light quality, the space experience continuously develops upward and inward, and the space experience becomes brighter, lighter and wider.
