Daminghu 100 Culture & Arts Center | TAOA

It's a building renovation project. In an old traditional neighborhood, the base is located on the south shore of Jinan DaMing Lake. The building has been transformed from offices and a hotel into an artistic and cultural complex, opening up to the city with a simple and distinctive personality, reuniting the natural landscape of lake and the lakeside historical and cultural district, activating and bringing new vitality to this historic city.

With a more open attitude, the client hopes that the building will become a gathering place for urban culture and art, bring new experiences to this gray-based old town, and lead new cultural life in Jinan. For this, design starts from the original basic condition of the building.

The building is the reinforced concrete frame structure, and the floor slab adopted a prestressing system. Low floor heights and the lack of connection among floors shackle the openness and freedom that art spaces should have. From the inside out, we reorganized the building's function, creating the freedom and proper variation of the interior space, thus affecting the facade and connecting with the open view of DaMing Lake.

We separate some relatively independent and closed functions to form multiple independent "boxes", which are freely stacked, staggered and squeezed within the framework of the six-storey space, blanking the homogeneous structural columns, and breaking the horizontal limitation of the floors. The blank-leaving among the "boxes" become open functions, creating a column-free public space that crosses the floor, flows freely and grows vertically where the upper and lower floors connect. The corridor of horizontal traffic function is also integrated into the public space and interconnected. The original structural frame and floor panels were visually liberated.

The changes in the core are reflected in the façade and shape of the building. The open public space vacated by the "boxes" maximizes the scenery of DaMing Lake on the north side and the sunlight on the south side into the interior, and the squeeze of the "boxes" creates a more permeable interior space of the building, from the inside out, strengthening the sense of transparency of the landscape at the external opening.

The definition of the functional attributes of building is not a very clear distinction, and human use cannot be simply regulated. Not limited by the original floor height, we use the location of the floor slab that has been demolished and modified in the creation of internal space to open up the connection among floors and establish a new space height of the public part, and also reduces the secondary damage caused by the original structure.

The building combines art galleries, theaters, art bookstores, cultural and creative space and art education into complex with different attributes and atmospheres, and related commercial behaviors rely on these open places. Art and commerce are blended together without clear physical boundaries. Art galleries, art bookstores, and cultural and creative space run through multiple floors through public staircases at the openings of the floors, allowing for maximum sharing of art spaces. 

We add a fully open transportation system in the cross-level public space and retains the convenience of vertical elevators. The spiral staircase extends vertically like a sculpture, connecting the platforms of different heights. Open traffic constantly shifts positions in the space, traversing different functions in roaming, increasing the sense of experience of the building and connecting the floors to the ground. 

To make these stacked "boxes" a whole, we wrapped the surface of the building with aluminum sheets. Echoing the interior space, punched aluminum plates with different permeability produce the transparency required, so that the wrapped "boxes" space can be perceived by pedestrians walking on the street. The aluminum plates are folded out of the corrugated shape, so that it can generate enough stress on itself without creating excess structure. The punched aluminum panels as windows of independent space, and together with the blank-leaving among the "boxes", are superimposed on the facade, forming staggered layer imprints of different sizes. At the same time, the public part has become more open.

At night, interior lighting shines through surface holes and openings, rendering the entire building warm. Due to the staggering and continuity, the internal become both independent and mixed, forming a three-dimensional, abundant, open and free art life experience center.

The original equipment is moved and the roof is transformed into a covered semi-outdoor dining event venue, which offers panoramic views of DaMing Lake and the beautiful scenery of Jinan's historic city.

这是一个旧楼改造项目，基地位于济南大明湖南岸,建筑置身于略显老旧的传统街区，北侧面对的是明艳开阔的大明湖面。建筑改造前由曾先后作为鲁信集团的办公楼和静雅大饭店，而新的建筑将作为艺术文化空间向城市开放，身兼美术馆、剧场、艺术书店、文创体验、艺术教育和特色餐饮等，以全新的多功能复合型艺术空间重新聚合大明湖的自然景观与湖畔的历史人文街区，以简洁鲜明的建筑个性重新激活这片老城区，给这个历史丰厚的城市带来新的活力。

委托方希望赋予建筑以新的气象，以更为开放的姿态成为济南新的文化生活的引领者，成为城市文化和艺术的聚集地。为了建筑的新的目标，也为了给这个灰色基底的老城区带来新的体验，我们的设计是从建筑原有的基本条件开始的。

建筑原结构为均质的钢筋混凝土框架结构，楼板采用预应力系统。楼层之间除了楼梯间几乎没有任何联系，不太富裕的层高，这些都桎梏了建筑作为艺术空间所应有的开放和自由。于是我们将建筑新功能重新梳理，希望找出一个由内而外的思路，从根本上解决内部空间的自由和应有的变化，从而影响到外立面，并和北侧开阔的的大明湖景色建立联系。

我们将一些独立的功能分离出来，形成了一个个独立的空间，利用这些相对独立与封闭的功能形成的“盒体”，消隐掉行列均质的结构柱，打破楼层的水平线的限制，在六层高的空间框架内自由堆叠、交错、挤压。这些盒体之间所留出的空白成为了公共和开放的功能，塑造出一个穿越楼层的、流动的、自由生长无柱的公共空间，各层公共空间在上下层连通的位置垂直生长，水平交通功能的走廊也被融入到公共空间，相互联结成一体。而原有的结构框架和楼层板得以从视觉中得到解放和消隐。

这些内核的变化自然会反映在建筑的立面和外形上。盒体空出的空白，作为开放的公共空间将北侧的大明湖风景和南侧的阳光最大限度地纳入建筑内部，“盒体”的挤压使建筑产生了更具通透性的内部空间，由内而外，更加强化了外部开口处景观的通透感。

建筑的功能属性的界定并非非黑即白的，人的使用也并非可以被简单规范的，也正是因此，在内空间的营造上，将原结构被静雅饭店拆改过的位置，重新拆除部分楼板，一来尽可能不给原始结构带来二次伤害，而来借此机会打通楼层之间的联系，建立公共部分的新的空间高度，使之不受限于原有的层高。

建筑以美术馆、剧场、艺术书店、文创体验和艺术教育组合成不同属性与氛围的艺术空间，与之相关的商业行为都依托于这些开放的场所，艺术与商业交融在一起，没有明确的物理界限。美术馆、艺术书店和文创体验通过上下层开口处的公共楼梯贯穿多个楼层，使艺术空间得到最大的共享。

新建立跨层的公共空间中增加的完全开放的交通系统，旋转楼梯如雕塑般垂直延伸，连接不同高度的平台。设计保留了垂直电梯的便利性，而新增的开放的交通 在空间中不断转换位置，在漫游中穿越不同的功能，增加了建筑的体验感，使各个楼层与地面建立了联系。

为了使这些被堆叠的合体空间成为一个整体，我们将建筑体的表面包裹了一层铝板，为了使之能够和内部空间呼应起来，铝板被设计成不同通透率的冲孔铝板，这样可以产生所需要透明性，使得被包裹的盒体空间可以被街道上的行人感知，为了通透的铝板背后不产生多余的结构，我们又将铝板折叠出瓦楞状，使自身可以产生足够的应力，通过冲孔铝板形成独立空间的窗，和公共空间的空白一起叠加在立面上，形成了错落有致的大小不同的图层印记，崭新的立面就形成了，公共部分也更凸显出了开放性。

夜晚时分，内部灯光从表面的孔洞和开口中透射出来，将整个建筑渲染成一盏温润的明灯。内部空间因错动和连续变得既独立又混合，形成了一个立体的、丰富的、而又开放自在的艺术生活体验中心。

原有放置在屋面的设备被移走，改造成了有顶棚的半户外餐饮活动场地，这里可以一览大明湖的全景，尽情享受济南历史名城的美丽风景。
