The site for Haiyang Road School is located at the junction of Chengdu’s Tianfu New Area and the High-tech Zone, a one-hour drive from the old city center. The site is regular in shape, surrounded by 100-meter-tall residential buildings on the west, south, and north sides, creating an oppressive sense of enclosure. Only the east side—facing Tianfu No. 5 Primary School and Kindergarten—offers a relatively open outlook. This is a typical plot of land created by rapid urban expansion. The surrounding area lacks cultural context, and the standardized road cross-sections, homogeneous building outlines, and uniformly spreading street textures make it difficult to determine its affiliation. Chengdu is often cloudy with little sunshine, and it is particularly tolerant of east-west orientation. People here love the outdoors and have a lively, down-to-earth atmosphere. The residential buildings surrounding the site are filled with outdoor stalls, creating a strong local atmosphere. On clear days, the outline of the snow-capped mountains can be faintly seen in the distance, and the long shadow of the houses on the west side slowly covers the site like a curtain. We transformed the surrounding residences into a place resource, and by taking advantage of the shadows, we placed the playground between the surrounding buildings and school buildings. This not only maximized sunlight and alleviated the sense of oppression, but also made this long shadow the most natural dramatic backdrop for the campus, reshaping the urban structural relationships. Here, shadows are no longer a symbol of oppression; instead, they serve as a medium connecting the land, the climate, and the human body, infusing the daily life of the campus with a sense of time and theatricality.The design attempts to draw an analogy between the "inside, outside, and in-between" of a space and the "rooms, courtyards, and alleys" of a campus. We abstract the various functional spaces on campus—regular classrooms, functional classrooms, canteens, gymnasiums, libraries, lecture halls, etc.—as a collection of "rooms". The rooms, streets, and courtyards are interwoven and orthogonally distributed, flowing freely and extending towards the site boundaries. Children can wander through these streets and alleys, unexpectedly meeting in the corners, or simply zoning out on the grass under a tree. This kind of free exploration represents a quality that is all too rare in modern campuses. The spatial layout is also designed for growth, capable of adapting to future uncertainties in usage and educational diversity. A large sports ground at ground level offers flexibility for the city; The "rooms, alleys, and courtyards" can be interconnected, allowing teaching to break through the boundaries of traditional classrooms and collectively form an expandable learning field. Furthermore, the large platform can be flexibly expanded in combination with various spaces, forming an organic whole that continues to grow as needs evolve. 13 settlement volumes made of "rooms," 10 courtyards of varying sizes, and spaces of varying widths both inside and outside the elevated second-floor platform—weave together to form a campus that grows organically.
