Located in the heart of Chengdu Plain, Wenjiang was the birthplace of Yufu kingdom in ancient Shu over 4000 years ago. It is known as “Golden Wenjiang” for its abundant land and prosperous industries. Chengdu New Century Foreign Language School is a famous school in Wenjiang. Founded in 2000, it has been regarded as a leader of Wenjiang education. With the continuous expansion and high-level development of school scale, Wenwu campus, the old campus in Wenjiang City, can no longer meet the demands. Therefore, the construction of Guanghua campus of Chengdu New Century Foreign Language School, located in the direction of Guanghua Avenue, was started.

There are several contradictions in this project. The first is the contradiction between a variety of functional requirements and extremely compact land use. Secondly, the three-stage coordination system of elementary school, junior high, and senior high brings the contradiction of spatial integration and separation of students across age span. Thirdly, the contradiction between dense construction and environmental space quality. Finally, the construction goal of high-quality campus with extremely limited engineering investment. These contradictions have become difficult points for design breakthroughs, and have led to repeated tempering of creative ideas. We persist on our design concepts of respecting the surrounding environment externally and integrate into the urban design; we strengthen the sharing of the field internally and create the memory of the place; we insisted on people-oriented, thinking from the perspective of the core users—students; and we convey the idea of inspiring young people’s dreams while protecting their sturdy growth in our space design. In the general graphic design and single graphic design, we reflect on the interpretation of a new era education mode with the requirement of healthy growth of children and adolescents. In the architectural form, facade, and detail designs, we aim to isolate noise, fulfilling natural light requirements, and achieve other physical environment conditions.
Following the contradictions and ideas mentioned, we refined a method of “linkage pile” in the design. Linkage Pile provides us a new mode of exploring the creation of a high-density campus suitable for teaching and living on extremely restricted sites, and practicing a large-capacity and high-quality teaching building with low technology and limited cost.

Spatial Pile Strategy
The design task requires the land to contain 42 classes of high school classrooms, laboratories, and offices, as well as 24 classes of primary school classrooms, laboratories, and offices. If the space is completely spread out, the site is far from enough to contain 12 grades, dormitories of 3000 students, canteen of 2000 students and 300 teachers, grand auditorium of 1500 people, and small auditorium of 400 people. Moreover, the project has to also contain fieldhouse of 800 people, separate sports grounds and stands for elementary and high school, 7-lane heated swimming pool, an office building, guard rooms, enrollment station, and etc. Thus, we designers put forward the strategy of “spatial pile” to stack up various functions, which may be the only reasonable and effective design direction.

In the teaching building, the meandering folding ruler shape lengthens the daylighting surface, thus fulfilling the daylight requirements and noise isolation conditions in the classroom area. In areas that cannot satisfy a classroom condition, we set up the laboratory and other auxiliary rooms, and then stack the office room on the floor above the classroom. In addition, the large space of the fieldhouse is designed to be multipurpose: meeting the functional and capacity requirements of large-scale assembly and artistic performance through altering internal arrangements. This design avoids the repeated construction of the grand auditorium with low utilization rate, thus saves the investment. At the same time, the multifunctional fieldhouse is stacked on top of the two-story student canteen, and the basement is equipped with a staff canteen. The lower space is designed with a sunken square to improve convenience and comfort. The concentrated dining area facilitates meal preparation and distribution. The heated swimming pool is put into the semi basement space formed under the activity platform at the main entrance. The small auditorium is stacked under the activity platform behind the stand of the elementary school sports ground. The enrollment station is stacked on the upper layer of the guard room at the main gate.

Through spatial pile, the project is condensed into five main buildings and two guard rooms. Two north-south oriented elementary and high school sports grounds are arranged on the east and west sides of the project. On this basis, a zone distribution of high school area in the west, elementary school area in the southeast, residential area in the northeast is formed. The junior high teaching building and the dormitory building are on the north side near the street. Between two buildings, there are the main entrance square and the campus’s main entrance of over 30 meters wide. In the elementary school area, the teaching building and the sports ground form an open axis to the east. The compact campus not only establishes the logic of multiple axes in the interior, but also opens “green” to the surrounding areas, contributing to a “virtual” urban interface.

Function Linkage Strategy
For such a boarding school, the limited project land not only carries the teaching function, but also is a place for 3000 students of 12 grades to live 24 hours each day. New teaching mode, rich learning experience, and high consumption of limited space are the problems that need to be solved by designers. Comfort under any circumstances of weather must be taken into account. Therefore, in the design of four core buildings on campus, which are high school teaching building, primary school teaching building, canteen and fieldhouse, and student dormitory, the corridor is used to form an all-area connection. The library, lecture hall, canteen, fieldhouse, also the grand auditorium, thermostatic swimming pool, and other facilities with high frequency of use are interspersed in the ground floor of each building or the accessible place on the ground floor. Students in any area can easily reach any places through the corridor.

With the strategy of zoning layout and functional linkage, students of different ages and different functions are placed in different spaces, and a free flowing traffic path is created. This is a space order built by a variety of transition spaces, such as building veranda, corridor, ground floor overhead, stadium viewing platform and activity platform, which run through each building volume. The functional spaces of different scales and different personalities are organically linked together, which provides a more convenient path and shelter for each user.

Organic linkage strategy is not only a series of functions, but also a great increase of the accessibility of campus space, which increases the sharing degree of public space such as library, fieldhouse, lecture hall, canteen, and atrium space. It avoids the repeated construction of homogeneous space, and also expands the application of functional space for different users. The traffic path within architectural space is no longer simply and linearly extended, but rather migratory, changeable, virtual while realistic. Students can enter the open and continuous transition space by opening the door, and they can experience constant changes in the process of moving. Such series of open and diversified campus places not only make the use of space more efficient, but also provides extra interests, which is an essential space quality for a school that can accommodate more than 3000 teachers and students.

Low Tech Vitality Strategy
The extremely compressed project investment and construction period determine the design to choose the route of low technology and low consumption. As a result, ZZHK designers give up the expression of special-shaped space, complex structure, and other dazzling technology. Instead, they use natural architectural technology to explore the most direct space interaction between people and architecture — squares, which are grand in scale while simple in structure. Choice of ordinary building materials and conventional technology also enhances such square elements. However, the creation of facade features will not be abandoned under the restrictions. The creativity aims at giving vitality to the building. Each floor of the building is suspended with horizontal fillet hanging plate, and it is decorated with colorful wave pattern metal plate decoration, forming a simple, smooth and lively facade image. The architecture simulates a dancing ribbon fly across the campus. The grass in primary school area symbolizes the vigorous growth of pupils, and the blue in high school area symbolizes the sky of dream, striving to bring good psychological effects on the users.

In addition, the hanging boards on façade also has multiple benefits. First, as the high-density urban environment and its surrounding roads challenges the education space, the hanging boards on the classrooms away from the south and west urban roads and sports ground function to shading, noise reduction, glare avoidance, and ventilation organization. Secondly, the climate is often poor, which requires the intervention of air conditioners and air purifiers. At the same time, a clean room for students to use and store should be set up. The inner side of the hanging boards is also a hidden place for equipment and cleaning room. Thirdly, the hanging boards cover the outer wall of the building, reducing the requirements for the disposal of windows, walls and risers on the inner facade, creating conditions for optimizing the cost of the outer wall.
The simple and regular plane and facade design provides great convenience for the implementation of prefabricated buildings. The overhanging hanging board on the facade envelops the building, reduces energy consumption, improves the use function, and improves the environmental quality of the classroom. The green and blue “ribbons” interspersed, creating a light and smooth rhythm on the overall image of the campus. Thus, ZZHK Architects are able to activate the vitality of the project with low technology and cost.
