山中天艺术中心玄馆原为751园区内的工业厂房及其附属办公建筑，建成后成为山中天艺术中心的主力展馆。一期作为主展厅率先落成，主体内部东西两侧是混凝土柱，撑起40mm厚的混凝土折板屋顶，下面为近500m2的无柱空间。

Originally an industrial building and its ancillary office buildings in the 751 Park, Wind H Art Center (PhaseⅠ) was built to become the main exhibition hall of Wind H Art Center. The first phase was completed first as the main exhibition hall, with concrete columns on the east and west sides of the main interior, holding up a 40mm thick concrete folded slab roof, with a column-free space of nearly 500㎡ below.

设计思路很简单：将原有无柱大空间做成主展厅，夹层下方为小展厅，上方为公共教育及办公室。主入口保持原位，以北为艺术品商店。四个功能分区都要独立封闭，以保证主入口到内院的路径畅通。

The design concept is simple: the original large column-free space is turned into the main exhibition hall, with a small exhibition hall below and public education and offices above. The main entrance remains in its original place, with the art shop to the north. The four functional areas are enclosed independently to ensure a clear path from the main entrance to the inner courtyard.

利用空隙和零余部分置入一个混凝土的“巨石”，像空心的多孔结构，容纳门厅、照壁、楼梯间、洞口、前台、储物柜，连接并分隔四个象限，使各自独立又连通。并利用保留墙体形成纵横交错的洞口和两个不同标高的“通廊展厅”和“夹缝展厅”，其下容纳空调设备和库房，实现功能与形式的统一，并形成东西向和南北向的空间层次与观览节奏。

A concrete “monolith”, like a hollow porous structure, is placed in the gaps and fragments to accommodate the foyer, the illuminated wall, the staircase, the cavity, the reception desk and the lockers, while connecting and separating the four quadrants, making them independent and interconnnected. The retained walls are also used to form interlocked openings and two different elevations of the “gallery of passageways” and “gallery of slits”, under which air conditioning equipment and storage are housed, achieving a unity of function and form, and creating a spatial hierarchy and rhythm of east-west and north-south views.

“狭缝画廊”作为空间制高点，通过原结构间脱开的600mm狭缝和一组三角形侧高窗采光，向西俯瞰大展厅，并在北端形成另一个多孔空间，成为序列的收束。邀请艺术家张小川设计发光艺术装置“腔体与演生”，从入口斜墙的孔洞中连通前台和楼梯间两个区域，强化了虚实结合的形态特征。

“The Slit Gallery” is the peak of the space, lit by a 600mm slit between the original structures and a set of triangular side windows, overlooking the large exhibition hall to the west, and forming another porous space at the northern end as a closure of the sequence. The artist Zhang Xiaochuan was invited to design the luminous art installation “Cavity and Evolution”, which connects the reception area and the staircase through a hole in the sloping entrance wall, reinforcing the combination of real and imaginary forms.

整座建筑的形体和表面处理追求“含蓄的丰富性”，以期达到“朴实无华，生动多姿”的效果。以中国传统园林以实造虚以及虚实转换方法为参照，用虚空切挖实体，以实体创造虚空，用标高变化整合空间功能，合理调配疏密关系，并统一在可观看的界面中。

The form and surface treatment of the whole building pursues a “reserved richness” in order to achieve a “simple, unadorned and vivid” effect. In reference to the traditional Chinese gardening techniques of “creating virtuality from reality” and “transforming between reality and virtuality”, solid was cut by voids and, in turn, created voids. Elevation changes are used to integrate spatial functions, and the relationship between density and sparseness is rationalised and unified in a viewable interface. Through simple shape and diverse materials, the new and the old fit together, creating spatial and sensory layers and forming embedded and porous space.

通过朴素的造型与多元材料选择，使新旧契合、制造空间与感官的层次，形成反复嵌合、多孔多窍的空间。利用角落、缝隙和零余空间“造园”，通过梳理复杂功能来创造复杂空间，在最小尺度内完成高密度建造，尽量保留原有大空间，这样一来，小而密的新建部分在大而疏的保留部分中穿行，以疏密对比表达对城市日常历史的尊重，这些历史曾经也是日复一日的现实，写进新旧更替的时空褶皱中。

By using corners, gaps and spare spaces to create garden and creating complex spaces by sorting out complex functions, high construction density is achieved in the smallest possible scale, while preserving as much of the original large space as possible. In this way, the small and dense new parts traverse among the large and sparse preserved parts, expressing respect for the city’s everyday history by contrasting sparseness with compactness, which was and is the daily reality. Once was also a day-to-day reality, written into the temporal folds of the old and the new.
