项目位于一栋保留老厂房骨架的现代建筑(原世博会案例联合馆 3)的顶层，带有一个超大的露台。室内 32 米的大进深和仅3.5 米的净高给想要寻求空间突破的设计师带来了一定的难度:如何在相对局限的条件下满足两家公司日常办公的功能需求，同时还要赋予这个空间积极的功能，打造出一个博物馆级别的多功能展厅?

The building, the Expo Joint Hall No. 3, retains the structure of a preexisting old factory. With an oversized terrace, the project is located on the top floor of this building. The interior depth is 32 meters, but the height is only 3.5 meter this was a major design challenge due to we want to break this boundary. To meet the functional needs of daily work between the two companies was a challenge, too. In the end, we provide a space with useful functions and additionally bring a “museum style” multi-purpose exhibition hall.

原有建筑改为办公出租后保留了西侧的垂直客梯和东侧的自动扶梯。经过设计师反复推敲和论证，最终选定了更靠近路口且方便易达的垂直客梯作为上到四楼的主要方式。设计以“白色舱体”的电梯厅为起点，用贯穿南北的“反引力”会议厅和茶室将空间分为两个独立的区域，强化横向立面的延伸，同时利用环绕走道打造出回廊式的多功能展厅。

The elevator on the west side and the escalator on the east side were kept after the function changed to office usage. After many deliberations, we finally figured out that the elevator is more accessible and closer to the intersection. It becomes the primary entry to the fourth floor. The design starts with the white elevator hall that increases the extension of horizontal facade. The "anti-gravity" conference room and tea room divide the area into two individual spaces creating an encircling walkway that can be used as a multi- functional exhibition hall. This walkway surrounding the conference room has unlimited scenarios that can be used as a multi-function scene.

基础空间扣除结构和机电风管后实际净高只有常规的 3.5 米，加上较大的进深，整体略显昏暗和压抑。设计师将最大的会议室设置在此，整体抬高与地面相脱离，抬高的平台向三个方向延伸并出挑达 3.6 米。立面上利用楔形视觉误差，巧妙的将钢梁藏身于结构之内，所见之处只有不到一公分的厚度。尽管整个会议室体积感很强，但它的质量感却因此被大大削弱，传递出一种视觉上的“轻”。在顶面和地面限定下，形成一种戏剧性的“反引力”效果。同时，抬高并延伸出来的平台亦可以作为舞台和展台使用，在未来的运用中可随时增添内容，会议室周围留出环绕走道自然形成了回廊式的展示空间，营造出一个充满创造力的复合场所。

After placing the structure and the electromechanical air duct, the net height of the central area is only 3.5 meters. The largest conference room in this area and is separated from the ground with an elevated platform that extended 3.6 meters in three directions. The wedge facade creates an illusion to hide the steel structure inside of the construction. Although the conference room is considerably big, it generates a moderate and light appearance. Due to the contrast between the top volume and the floor a dramatic "anti-gravity" effect is formed.

中心区的大会议室正对北侧的露台，吊顶从会议室顶部一直延伸至室外形成雨蓬，立面上用同样的手法，使出挑达 11 米的雨蓬看上去轻薄如纸。在雨蓬的下方设有茶室，设计师希望茶室看起来与雨蓬非常接近但实际上又没有互相接触，因此将雨蓬的中间挖空，悬臂雨蓬夸张的出挑深度轻盈地遮蔽在茶室的上方，希望它们在保持这种张力的情况下进行对话。

The central conference room faces the north side of terrace. The ceiling extends from the top of the conference room to the outside awning. The same method that is used on the facade makes the awning, 11 meters long, looks as light as a paper. The tea room is under this area. The objective was to create an indirect connection between those two elements. In order to demonstrate this effect, the cantilevered awning is exaggerated and lightly shades the tea room.

由于受纵向条件的限制，因此强调横向立面的延伸，扩大空间的深度与广度，成为设计的基本原则。项目南临黄浦江，但受原有扶梯和机房的限制，实际拥有一线江景的面并不多，我们在这里布置了必要的前台、接待区和办公室，仍保留了一跨的开间，结合壁龛和门洞营造出一个内凹和穿透的盒子，江景资源亦得以用“镂空”的方式被引入前厅。前厅左右两侧的墙体以黑色钢板包裹，内凹的截面为温暖的木色，一冷一暖相互平衡又表现出与周边白色空间的强烈对比。凹凸错落的壁龛，打破了单面展示墙的乏味感，对于立面的延伸和空间的收放变化起到了积极的作用。同时设计师在设计中利用了顶层的优势，将局部屋面打开，最大化的把阳光引入室内。当阳光穿透天窗，光线形成的虚影赫然投射在地面上，随着时间的推移，整个区域呈现出不同的光影氛围，让原本封闭的空间具有了延展性。原设计方案中天窗下方还设有一部通往屋顶露台的楼梯，经多次和物业协商后最终未能实现，留下了一些遗憾。

Although the project is located on the south of Huangpu River, there are not many front-facing river views because of the restrictions by the original layout and the position of the escalators and facilities rooms. The principle of the design became emphasizing the depth and breadth to extend the lateral facade. We planned the front desk, reception area, and offices near the entry. The niche creates a recessed space and river view can be seen through this "box". The walls on the left and right sides of the front hall are covered with black steel panels. We use wooden plates to surround the inner face of this box. The balance between cold and warm materials create a strong contrast with the white space around this area. The staggered wall niches break the monotonous environment enriching the design of the facade. We take advantage of the rooftop and placed a skylight to introduce natural light in the room. When the sunlight penetrates through the skylight windows, the shadows reflected on the floor create different patterns at different times of the day. In the original design, there was a staircase leading to the roof terrace under the skylight, but the idea was abandoned due to multiple reasons.
