Appreciation towards Architecture School of CAFA for providing the following description:

北区礼堂原来是作为阶梯教室使用。此次改造是为了提升空间以及设备品质，用以举办国际会议，同时作为学院的学生活动中心。在传统的观念里，礼堂空间象征着荣誉感与秩序，其所呈现的是内向的，程式化的稳定性。然而，基于当下美术学院开放、灵活的教学氛围，我们将礼堂定义为校园公共空间的一部分，让它成为集校园活动、学术交流、集会等多元化的交互场所。

Auditorium in North Campus was originally used as a lecture hall. The renovation is designed to expand the space and improve the quality of the equipment, which will be used to host international conferences, and to serve as the student activity center. In the traditional concept, auditorium symbolizes sense of honor and order, which presents introverted and stylized stability. However, based on the current open and flexible teaching atmosphere of college, we define the auditorium as a part of the public space of the campus, and make it a diversified interactive place for campus activities, academic exchanges, assemblies and so on.

空间拓展|Spatial Expansion

场地的最大问题在于内部公共空间的局促与外部环境的杂乱且浪费。首先，我们打掉正面外墙，将原有较为狭窄的前厅向广场延伸；其次，拆除了门厅南侧墙面，让常年废弃的花架纳入到室内中，并利用临近绿地设计了一个微型花园，使其成为面向景观的独立阅读区；最后，扩大了入口门斗的面积，增加了一个从侧面进入阅读区的路径，建筑南侧由此形成了一个围绕景观的院落围合。

The biggest problem of the auditorium is the constraint of the internal public space and the disorder and waste of the external environment. First of all, we knocked off the outer facade so that the original narrow front office can extend to the square. Secondly, we removed the wall of the south side of the hall, so that the abandoned flower-shelves were incorporated into the interior, and designed a miniature garden with adjacent green space, making it an independent reading area facing the landscape. Finally, we enlarged the area of the foyer of entrance, and added a path from the side to the reading area, forming a courtyard surrounding the landscape on the south side of the building.

窗景与舞台|Window Scenery and Stage

建筑正立面是一个6米高，20米宽的折面巨大橱窗。白天，它将外部景观纳入室内以得到最大限度的采光和开阔的视野。到了夜晚，从室外像室内望去，由于室内地台相比室外地面升高了90公分，因而自然形成一个面向外部广场的“舞台”。人们的视线所观看到的内部活动场景就像是一出生动的舞台剧。

The facade of the building is a huge folding window, 6 meters high and 20 meters wide. In the daytime, it incorporates the exterior landscape into the interior to get maximum lighting and an open view. At night, looking from the outside to the inside, because the indoor platform is 90 cm higher compared to the outdoor ground, so it forms a stage facing the external square naturally. The inner activity is like a vivid stage play.

新建的折面钢板与原有建筑构件相互穿插生成若干连续的“视窗”。这些窗景沿着人们的行走过程产生由私密到开放的变化。其核心意义在于打破室内外的边界，为学生创造一个开放、生动和有趣的活动场所。

The folding steel plate newly constructed and the original building components intersect each other to form several continuous windows. These windows change from privacy to openness as people walk. Its core meaning lies in breaking the boundary between indoor and outdoor, and creating an open, vivid and interesting activity place for students.

南侧由于新旧结构的并置所形成的视窗经过微型花园的介入，有效的隔离了室内与外部广场环境。人们的内部活动透过院落吸引着外面人的视线以产生“窥视”的趣味。

The widows formed due to the juxtaposition of old and new structures with the intervention of miniature garden, the south side effectively isolates the indoor and external square environment. People’s activities inside the building attract people outside through the courtyard to create the interest of peeping.

红与黑的空间构成|The Space Composition of Red and Black

蒙德里安说：真正的造型表现，只能通过形状和色彩的动势平衡来表达“纯粹的实在”。受此启发，我们让楼梯的红色在空间起到控制构图和平衡的作用。原有外墙被拆除后所形成的框架被强化成两个巨大的景框。透过其中，楼梯展现了黑与红的图形关系。当人们站在窗外，可以透过景框感受形状与色彩相互叠加的戏剧性。也让楼梯成为了一个充满形式感的“秀场”。

Piet Mondrian said, real modeling was purely abstract compositions that expressed a dynamic balance through black grid lines and blocks of primary colors on white and grey grounds. Inspired by this, the red of the stair has the effect that controls composition and balances in the space. The frame formed after the removal of original outer wall was reinforced into two huge window frames. Through them, stair showed the graphic relation of black and red. When people stand outside the window, they can feel the dramatism overlapping of shape and color through the frame. The stair also becomes a show field full of sense of form.

校园公共空间存在的意义就是让师生们产生“使用”的欲望，因为“使用”是实现人与空间交互的重要方式。在美院理性、严谨的灰砖建筑背后，是一个个无序而具有活力的艺术与文化生活场景。我们希望改造后的空间能够成为展现这些场景的舞台。

The significance of the existence of campus public space is to make teachers and students have the desire to use, as “use” is an important way to realize the interaction between human and space. Behind the rational and rigorous grey brick architecture in the Central Academy of Fine Arts is various scenes of art and cultural life with disorder and vitality. We hope the space after renovation can be the stage to show these scenes.
