The pumping station has been abandoned for many years, staying lonely in the neighborhood. People passing by,never realize its existence nor even take a look at it. However, ，mottled walls and wild vines hide a lot of memory. It is the architect's topic to revive its existence. The client wants to convert it into an office of 8-10 occupants. Space is the essence of architecture. Our strategy is to maintain its structure and spatial relationship, and eliminate superfluous decorative elements, dig out its inherent memory and value.

Different from the common buildings,the pump house has many holes on the floor for device use , and two exhaust chimneys on the corner. Although these components are no longer used, we still reserve and convert them into new building elements to have a dialogue with the old memory.

As the office is settled in a residential area, the privacy of the office is one of the most important factors in this design. We locate the terrace on the south facade which is away from the residential buildings. On the north facade which is visible from the residents, we built a solid wall with a skylight and a bottom ribbon window, which makes the space mysterious but not depressed. The pumping station is six meters high, with lots of high-side windows . An added mezzanine space can take advantage of these windows. What we only need to do is to adjust its size and proportion slightly. We convert the original underground water storage space into a basement. In order to avoid risks of bio-gas, the basement entrance is located outdoors,where cantilevered steel steps can be located between the gap of the arc retaining wall and the main building. Two old trees adjacent to the building look more prosperous in front of the pure white wall.

一个废弃多年的泵房，独处于居民区的深处。小区里朝九晚五的人们，甚至不会多看它一眼。斑驳的墙体，恣意的藤蔓留藏着许多记忆。如何重塑它的存在，是建筑师思考的课题。业主想要把它改建成能容纳8-10人办公的场所。空间是建筑的本质。我们的策略是在保留其结构和空间格局不变的前提下，剔除多余的装饰构件，挖掘其内在的空间记忆和价值，赋予其应有的气质。

不同于普通的建筑，泵房的楼板上为器械预留了许多吊装孔，墙角上也设置了两个排气烟囱。这些构件虽然不再使用，但仍然被我们保留下，通过建筑手段加以利用，与旧时的空间记忆展开对话。

由于身处居民区内，办公室的私密性也是要解决的问题，我们将室外平台设置在背对居民区的南侧。北侧通过加建的实墙，与居民的视线隔绝。而顶部的天窗和底部的条窗则与户外空间产生联系，使空间神秘而不压抑。泵房有六米的层高，开了很多高侧窗。加建的夹层空间正好可以利用这些窗，只是对其比例尺寸稍有调整。原有的地下储水空间被我们改造为地下室。为避免沼气的隐患，我们将地下室的入口设于室外，利用原来的弧面挡土墙和主体建筑的空隙，布置了悬挑楼梯。紧贴着建筑生长的两颗老树，在纯净的白色墙面的映衬下，更显得生机盎然。
