Text description provided by the architects. Located in the trendy Sanlitun area, a 60-year-old auditorium that has seen multiple transformations now houses Crossboundaries’ new office.

在搬进来之前，跨界公司开始了整栋大楼上层的设计，创造了一个现代的商业空间，包括办公室和公共空间。一个新的屋顶，均匀地散布天窗，添加到原来的结构，一个前礼堂，从50年代开始。它的上限被提高，以便在新插入的程序中有足够的空间供夹层水平使用。让墙壁裸露的决定，暴露了它过去和新的转变，揭示了建筑物的历史和以前的业主的故事。

Before moving in, Crossboundaries took up the design for the whole refurbishment of the building’s upper level, created a modern commercial space with offices and public space. A new roof, evenly scattered with skylights, is added to the original structure of a former auditorium from the 50s. Its ceiling is raised to allow adequate space for a mezzanine level in the newly inserted program. The decision to leave the walls bare, exposing its past and new transformation, reveals the story of the building’s history and previous owners.

内部跨越边界将空间划分为四个独立租赁办公室。这四卷书被推向外墙，在中间形成了一个高耸的中庭，供流通和活动之用。在办公区域内，独立的夹层地板形成空隙，与原来的外墙流通，空气和光线从天窗过滤。窗户打开进入中庭，开阔了使用者的视野，扩展了他们对开放式平面图的感觉。

Internally Crossboundaries divides the space into four offices for independent leases. These four volumes are pushed toward the outer walls forming a lofty atrium in the middle for circulation and events. Within the office areas, freestanding mezzanine floors form voids with the original outer walls for circulation, air and light filtering from the skylights. Windows open into the atrium broadening the view of its users, extending their senses of the open floor plan.

跨越国界目前占据着中庭尽头的办公室。到达时，主楼层是一个很大的空地，用作会议和接待区，阁楼层作为工作空间。两个层次平行运行的服务区被插到办公室的后面，用可移动的引脚板进行分层。在主地板上，隐藏在连续墙后面的是一个储藏室和一个小型会议室，而夹层地板则存放着材料和参考资料库。

Crossboundaries currently occupies the office at the end of the atrium. Upon arriving, the principal floor is a large open space serving as meeting and reception areas, the mezzanine level functioning as workspace. A service area running parallel across both levels is plugged into the back of the office layered with movable pin boards. On the principal floor, concealed behind a continuous wall are a pantry, storage room and a small meeting room while the mezzanine floor holds the material and reference library.

为了标志着新办公室的完工，跨界公司为其开业方创建了一个装置。将数百米长的红线插入中庭的空间，用灯光将人的影子投射到白色的墙壁上，这一装置以充满活力的活力吸引了办公室外的客人。

To mark the completion of the new office, Crossboundaries created an installation for its opening party. Inserting hundreds of meters of red string into the atrium’s volume with lights casting shadows of people to the white walls, the installation engaged the guests beyond the office space with vibrant dynamics.
