这个占地4.5hm2的新建公立中学位于北京西南五环外的一个新城的中心，是著名的北京四中的分校区。

学校的功能空间被组织成上下两部分，并在其间插入了花园。垂直并置的上部建筑和下部空间，在“中间地带”（架空的夹层）以不同方式相互接触、支撑或连接。

下部空间包含一些大体量、非重复性的校园公共功能，如食堂、礼堂、体育馆和游泳池等。每个不同的空间，以其不同的高度需求，从下面推动地面隆起成不同形态的山丘并触碰到上部建筑的“肚皮”，它们的屋顶以景观园林的形式成为新的起伏开放的“地面”。上部建筑是根茎状的板楼，包含了教室、实验室、学生宿舍和行政楼等。在这个巨大的结构中，主要交通流线被拓展为创建社交空间的室内场所，其中还包含为小型的群组活动提供半私密的围合空间。教学楼的屋顶被设计成一个有机农场，为36个班的学生提供36块实验田，不仅让师生有机会学习耕种，还对这片土地曾作为农田的过去留存敬意。

Situated in the center of a new town just outside of Beijing's southwest fifth ring road, this new public school on 4.5hm2of land is designed as the branch campus for the renowned Beijing No.4 High School.

The intention of creating more open space filled with nature, something that today's urban Chinese students desperately need, combined with the space limitation of the site, inspired a strategy to create multiple grounds on the vertical dimension, separating the programs into the above and the below and inserting gardens in-between. The juxtaposition of the resultant upper and lower buildings, connected at the "middle-ground" in various ways, is as much an interesting spatial strategy as a signifier of the relationship between formal and informal educational spaces in the new school.

The lower building contains large and nonrepetitive public functions of the school, such as the canteen, the auditorium, the gymnasium, and the swimming pool. Each of these spaces has varied height requirements and pushes the ground up from below into various mound shapes that touch the "belly" of the upper building. Their roofs become the undulating new open "ground" in the form of landscaped gardens. The upper building is a thin rhizome-shaped slab that contains the repetitive and rigid programs of classrooms, labs, dormitories and administration offices. This mega form extends, bends, and branches, but all are connected together. The main circulation spine within this mega structure is widened to allow rapid foot traffic during class breaks. It also accommodates some semi-enclosed spaces for small group activities, as a river with organic-shaped islands. The roof-top of the upper building is designed to be an organic farm, with 36 plots for the 36 classes of students in the school, providing them the opportunity to learn farming techniques while paying tribute to the site's pastoral past.
