架构师提供的文本描述。现有仓库位于北京北三环某航空厂房内，为三湾36米深的混凝土结构，前两个海湾高度4米，上海湾空间7.8米。设计的关键问题是，通过在4米高的空间中插入一层夹层，在顶部创造额外的工作区域，并在其下面建立存储空间，从而为工作区保留完整的高度空间。夹层极低空间与主区域极高空间之间的对比产生空间张力。在悬臂楼板下面有一个壁龛，就像模型显示的那样。原来的正面被拆除，并转变成全高度的玻璃，以显示插入的白色体积的干预。休息室，作为一个新的元素，从正面投射出来，变成一个展示。

Text description provided by the architects. Located in an aeronautical factory on North 3rd Ring of Beijing, the existing warehouse is a three bay 36 meter deep concrete structure, with 4 meter high space in first two bays and 7.8 meter space in last bay. The key issue of design is to preserve the full height space for work area by inserting a mezzanine floor in 4 meter high space, creating extra work area on top and storage space underneath it. The contrast between very low space on mezzanine and very high space of main area generates a spatial tension. A niche underneath the cantilevered floor functions as the model displays. The original facade is demolished and changed into full height glazing to reveal the inserted white volume of intervention. The lounge room, as a new element, is projected out from facade and turned into a showcase.

新元素的主要材料是钢板、霜冻玻璃、白色石膏板墙和乙烯基地板，以产生纯体积的抽象，而混凝土、钢和木材等现有元素的原始材料则通过去除油漆来重新暴露，以强调其构造。因此，新元素的抽象与重纹理的现有结构形成了强烈的对比。

While the major materials used for new elements are steel plate, frost glass, white gypsum board wall and vinyl floor to create abstraction of pure volume, the original material of existing elements such as concrete, steel and wood is re-exposed by removing the paint so as to emphasize its tectonic. Thus a strong contrast is created between the abstraction of new element and heavy textured existing structure.
