思考

2018年，在广西壮族自治区柳州市白露新区的柳江边，我们接到了一个城市展览馆委托，场地是在一片规划好的城市公园里。通过对设计任务的解读，我们发现展览馆的建筑体量和用地要求，与城市公园要求的开放性、通过性，形成了一组需要调和的设计问题；并且城市展览馆的独立性空间与城市公园公共性空间相结合，也产生了空间上的不连续问题。所以在前期设计中，这两方面给到我们一定的挑战，但是也给予了一个机会让我们用一种更非常规的方式去设计这座展览馆。

建筑师作为城市成长的发起者之一，在实践与教育中，建筑师群体大概形成了一套价值观和方法，那就是‘公共利益与私人利益之间取得平衡，争取优先考虑公共利益’。所以当我们思考这个可能会是非常规的展览馆时，实际上是我们如何在各方利益的驱动下去还原、去实践这套建筑师的价值观。

项目地址位于柳州市白露新区临柳江北的一片开发区中，前身是一个江边小村，也是一个后工业用地。柳州是广西里一个相对特殊的城市。几十年前，她和姐妹城市梧州是全国为数不多的准一线工业城市，有强大的重工业基础，汽车、钢铁、化工……在那个特殊的年代，重工业是中国对抗外国封锁的武器，是这个时代的印记，也是我们应该在场地的设计里面有所表达的。而在建筑师与委托人前期沟通的时候，也被反复提及如何在这个项目中唤起柳州人的骄傲感、认同感。

规划布局

回应展览场馆与公园的空间问题，为了保持公园的空间连续性与公共性，在概念方案中，建筑师提出把建筑完全埋藏在地下的想法。然后通过露出地面的透光裂缝和建筑本身呈现出来粗壮的几何结构，营造出一个‘工业光之森林’的秘境，既可以在夜间为公园提供照明，也可以以一种低姿态去提示市民地下存在一个有待探索的空间。

在展馆的布局及与周边公园的空间关系上，我们在概念设计阶段尝试利用了一些参数化的分析方法（UrbanSpaceDecoding），这个尝试使得我们可以在一个人为设定的大框架合理功能分区原则上，得到尽量多的公园&展览馆流线模拟结果，我们再在这个基础上进行选择和优化。最终我们优化出了一个展览场馆与公园空间品质俱佳结果。

Before design

In 2018, we had been assigned a design commission, which was a river side exhibition hall located in an on-going planning public park. Through a several weekssite and surrounding urban context study, we found out that the volume of exhibition hall together with its high were going to make the contradiction while considering a public park should be open and consistent in space. Furthermore, the independency of exhibition space would weaken the publicity of park. Therefore, in the conceptual design stage, these precedent conditions brought us many challenges; however, it also offered us the opportunity to use the new method to design this exhibition hall.

Architect as one of the developers for urban planning, through the design practice and architectural education, an acknowledged value system, which is always keeping the balance between private and public interests and try to put the public willingness in priority, has been formed. For this project, it is actually a experiment that we full fill the belief of architect value system while balancing the different interests from all the urban stake holders, e.g. the government, real-estate developer, residents......

The project site located on a development zone of Bai Lu new district of Liu Zhou city, where was a post-industrial zone, and used to be a river side village. In terms of the city, Liu Zhou is a heavy industrial basement city which holding a special position in the Guangxi province. A few decades ago, it was one of the most important industrial basements of China. Thus, the local people are very proud of this piece of history. While we discussed with the clients and other participants, we were always told to make link with this history.

Urban planning

Earth-shielded like architectural form has been regard as one possible way to reconcile the conflictions arose from the exhibition hall and park. There are cracks and sinking open space after we put the architecture under-ground. The light from interior spaces escape through the cracks and sinking open space could generate a sense of ‘industrial forest of light’; it could bring special visiting experience for the tourists and, most importantly, these lights throw the clue to the visitors that these is an unknown underground space to be explored.

While designing the circulation of the exhibition hall and its surrounding environment, in the conceptual design stage, we tried to apply the parameterization method, ‘Urban Space Decoding’, in order to get as much simulated results of circulation as possible. Base on the massive simulated results, we finally picked the most potential one and developed the master plan accordingly.

构思图

建筑

回应前面提出的展览馆与公园的兼容问题，建筑师构建了一套完整的逻辑语言。便是用内聚的、纯粹的几何形式，结合下沉、起伏、裂缝光的手法，去营造一个既谦逊又神秘引人的场所。在行为上、体量上，展览馆是完全不会破坏公园的公共性和通行性的建筑物。

具体来说，如果我们把整个场地看作是一整张卡纸，通过在上面刻出不同的十字交叉线，折起或按下不同的角，可以使我们的场地形成形态丰富的景观空间，或是小山丘，或是下沉庭院。与此同时，我们也把展览馆及其从属建筑消隐在最大的对称四个折角空间下。在前期设计我们制作了一个工作模型去表达我们的设计。

在展览馆建筑主体的中央，我们利用形体形成的下沉空间设置了一个中庭广场，这个空间把展览馆分散开的功能重新联结到一起，同时下沉广场也承载许多的活动。建筑的屋面使用了可上人的植草屋面，使得来公园活动的市民能够站在屋面的斜坡上鸟瞰下沉空间发生的事件，形成微妙度互动。

在功能方面，我们预留足够的高度给予两个主要下沉展览空间，方便其日后进行功能迭代。同时对于另外两个次要的下沉空间，通过与设备结构专业的密切配合，我们尽可能缩减了非必要的机电辅助空间，取而代之的，为我们利用这些空间边角料引入了一些服务居民的生活功能，比方说螺蛳粉、咖啡厅、社区书吧……目的是营造出多样的服务业态，希望她能在各方的运营参与下，更多的参与到市民的生活中，而不是仅仅作为一个城市展览馆。

Architectural design

In order to reconcile the conflictions caused by the exhibition hall and park,in terms of architectural design, we had applied a complete set of design language, which is by using the earthshielded like space and cohesive Euclidean geometry form. The goal is for constructing a humble, mysterious and interesting place. The exhibition hall will not ruin the publicity of park, no matter in the functional or volume perspective.

Specifically, for the massing, we cut several cross-lines on the card paper,then through pull up or press down the vertexes; we will get some interesting spaces, such as the mini mountains,sinking courtyards, slops……The volume of exhibition hall is hiding below the slops or mountains of four sides.

At the central of architecture, we design a sinking courtyard; it is not only the most important traffic space which is linking the separated volumes, but also offering a central stage for the exhibition hall operators to hold any activity.

Visitors can go up to the grass rooftop. At rooftop, they can observe the events and activities of the central sinking courtyard.

展望

柳州万科城项目，本质上是一次从无到有的城市塑造，如凯文林奇所说: 街道、广场、标志物、公园、住宅、学校……缺一不可。而城市展览馆作为复合型的重要城市节点，在未来将会对社区放射出巨大的影响，希望在日后的时间发展中，她能如我们所设想，包容角色变化的方方面面。

We set aside enough high for the interior spaces of the main exhibition zones, remaining the possibility of renovation in the future. In the meanwhile, for the rest of two secondary spaces,which are mainly for equipments and administrators, through worked closely with the equipment engineering consultants, we minimized the equipment spaces and substituted public service spaces,like restaurant, coffee, mini book store…… We try to design a compound exhibition hall, which is not only for showing stuff, but also for the daily life of residents.

Future & Expectation

Like Kevin Lynch wrote in his book ‘street, plaza, landmark, park, school, none can be dispensed with’. This project was actually a urban creating process from 0 to 1, and the Urban Development Exhibition Hall of Liuzhou should be a compound urban public space and post a positiveeffect to the neighborhood. We hope it can adjust itself to any change in the future urban development.
