昆明大华白沙湖虹桥鱼跃展厅，昆明/建筑设计

The project is located in Panlong District, Kunming. It is a part of the whole Baisha Lake urban design. We have participated in the urban design and fully understand the current situation and future appearance of the surrounding environment. The whole design should not only meet the use requirements at this stage, but also present the image of the whole area. This is a time axis.

建筑基地在白沙湖水库西南角，周边现状复杂，未拆迁的棚户区与西侧山崖上的既有建筑将基地包围，场地高差达到10m，并且唯一一条进入场地的道路小而逼仄，然而一旦高度抬高，湖光山色就尽收眼底。

The construction base is located in the southwest corner of Baisha lake reservoir. The surrounding current situation is complex. The base is surrounded by the unremoved shanty town and the existing buildings on the West Cliff. The height difference of the site reaches 10m, and the only road to the site is small and narrow. However, once the height is raised, the lake and mountains will be seen.

建筑选址上，我们选择了基地内最高的位置，并采用漂浮的空间形象，这样建筑能够跃过周边场地的嘈杂，获得1500m的水景视野。

In terms of building site selection, we have selected the highest position in the base and adopted a floating spatial image, so that the building can leap over the noise of surrounding sites and obtain a 1500m waterscape view.

视线设计

Sight design

建筑的形态与视线关系息息相关，如何“藏”与“露”，贯穿了项目的始终。

景观上要解决的一大问题就是如何经过前场小路，进入场地，合理的绿树与景墙，打造一条曲径通幽的小径，引导参观者进入场地。在小路最后一个弯处，建筑主体形象呼之欲出，景观顺势打造一个观景平台，这个平台能将建筑与湖面完整呈现。

整体建筑表皮在南侧高起，规避了不利视野，并且隐藏了屋顶的设备。

4层露台东北侧完全敞开，一览湖光山色，2层露台则用一个凹型线条，柔美的将建筑与湖面及远处的花之城地标建筑遥相呼应。

The form of the building is closely related to the line of sight. How to "hide" and "reveal" runs through the whole project.

One of the major problems to be solved in the landscape is how to enter the site through the front path, create a winding path with reasonable green trees and scenic walls, and guide visitors into the site. At the last corner of the path, the main image of the building is ready to emerge, and the landscape takes advantage of the trend to create a viewing platform, which can completely present the building and the lake.

The overall building skin rises on the south side, avoiding the adverse view and hiding the roof equipment.

The northeast side of the terrace on the 4th floor is completely open to view the lake and mountains. The terrace on the 2nd floor uses a concave line to gently echo the building with the lake and the landmark of the city of flowers in the distance.

而建筑首层在中部架空，是为了景观视线的引入，同时将未来片区内的两栋超高层地标纳入观景画框。

建筑内部2层主展厅用一道32m的长窗，最大限度的收入湖景，这条长窗也成为建筑形象上一道独特的元素，在入口转弯处的观景平台就可以看到。

The first floor of the building is overhead in the middle, which is to introduce the landscape line of sight, and bring the two super high-rise landmarks in the future area into the viewing frame.

The main exhibition hall on the second floor inside the building uses a 32m long window to maximize the lake view. This long window has also become a unique element in the architectural image, which can be seen from the viewing platform at the corner of the entrance.

建筑难点

Architectural difficulties

为完成建筑漂浮的构想，同时波浪状的外表皮在三维空间上呈现扭转的姿态，这些都对工程师与施工人员都提出了很高的要求。

结构上采用局部桁架，满足了建筑15m的空间悬挑，并且保证了内部空间的有效利用。

曲面幕墙在设计与施工中都有巨大的困难，项目面临着2276块相似而不同的板材加工及施工问题，同时每块板材上有着不同的穿孔肌理，这些孔在立面上呈现若隐若现的流线肌理。

In order to complete the idea of building floating, and at the same time, the wavy outer skin presents a twisting posture in the three-dimensional space, which puts forward high requirements for engineers and construction personnel.

The local truss is adopted in the structure to meet the 15m space overhang of the building and ensure the effective utilization of the internal space.

There are great difficulties in the design and construction of curved curtain wall. The project is faced with the processing and construction of 2276 similar but different plates. At the same time, each plate has different perforated texture. These holes show a faint streamline texture on the facade.

穿孔同样出现在架空层的镜面不锈钢吊顶上，镜面能否反射地面水景，视觉上加大了架空层的空间尺度，避免压抑，而这些穿孔配合灯光不仅能增加空间的丰富性，同时有效缓解镜面材质由于微小的不平整带来的视觉干扰。

The perforations also appear on the mirror stainless steel ceiling of the overhead floor. Whether the mirror can reflect the ground waterscape visually increases the spatial scale of the overhead floor to avoid depression. These perforations combined with lights can not only increase the richness of the space, but also effectively alleviate the visual interference caused by the micro roughness of the mirror material.

内部空间

Interior space

参观者由整个镜面不锈钢与水景交相呼应的架空空间进入一层大厅，一层大厅周围用全通透的玻璃幕墙包围，将阳光引入，并获得良好的景观视野。

Visitors enter the hall on the first floor from the overhead space where the whole mirror stainless steel and waterscape interact. The hall on the first floor is surrounded by fully transparent glass curtain walls to introduce sunlight and obtain a good view of the landscape.

参观者可通过一个标志性的螺旋楼梯或者电梯进入二层主展厅，这是一个850㎡的空间，并且拥有一个32m宽的长窗，能否俯瞰整个白沙湖片区，同时二层展厅南侧，就连着二层的露台，展厅向上，能够到达顶层的全景露台。

Visitors can enter the main exhibition hall on the second floor through a symbolic spiral staircase or elevator. This is an 850 ㎡ space with a 32m wide long window. Can you overlook the whole Baisha Lake area? At the same time, the south side of the exhibition hall on the second floor is connected to the terrace on the second floor. The exhibition hall is upward, and you can reach the panoramic terrace on the top floor.

建筑施工

Building construction

即便前期的设计及准备工作多么完备，施工中依然会遇到不少问题，这也是建筑设计必然面对的，因地制宜的建造。

首先在各施工方的工作分工上，为使各方了解建筑的设计需要，我们复原了完整的建筑数字模型，包括建筑、结构、室内空间、景观、幕墙结构、表皮、甚至设备管线，这样无论业主、建筑师、工程师、还是施工方，都能参考这个模型，从而对自己将要建造的这个建筑有所了解和研究。

在实际施工前，施工方建造了一个1:1的局部样板墙，用以研究表面铝板的拼接方式，如何精确高效，同时尽量避免内部构件对外观的视觉影响。

Even if the preliminary design and preparation work are complete, many problems will still be encountered in the construction, which is inevitable for the architectural design. The construction should be adapted to local conditions.

First of all, in terms of the division of work of each construction party, in order to make all parties understand the design needs of the building, we have restored a complete digital model of the building, including architecture, structure, interior space, landscape, curtain wall structure, skin, and even equipment pipelines, so that no matter the owner, architect, engineer, or construction party, they can refer to this model, so as to understand and study the building they are going to build.

Before the actual construction, the construction party built a 1:1 local sample wall to study the splicing method of surface aluminum plates, how to be accurate and efficient, and try to avoid the visual impact of internal components on the appearance.

另外，灯光也是一个重大的难题，不仅在样板墙，在实际施工中也进行了无数次的调试与试验，希望能形成星空的效果。

为更高效的完成整体的曲面效果，我们选择将曲面板切割成大小不同的三角平面板，整体拼接成曲面，但这样每块铝板都会与5块交接，铝板在安装中，面临的最大难题就是如何将每块板与周围板拼接在一起，呈现完美的交缝。施工方将2块三角板组合为一个单元，从而降低了施工的难度，加速了进程，最终两千多块不同的三角板，每块都拥有一个编号，分毫不差的安装完成，得益于业主、设计、施工、材料等整个团队的精诚合作。

In addition, lighting is also a major problem. Numerous commissioning and tests have been carried out not only in the model wall, but also in the actual construction, hoping to form a starry effect.

In order to complete the overall curved surface effect more efficiently, we choose to cut the curved panel into triangular plane plates of different sizes and splice them into curved surfaces as a whole. However, in this way, each aluminum plate will be connected with 5 pieces. During the installation of aluminum plates, the biggest problem is how to splice each plate with the surrounding plates to present a perfect joint. The construction party combined the two triangular plates into one unit, which reduced the difficulty of construction and accelerated the process. Finally, more than 2000 different triangular plates were installed with a number, each of which was completed exactly. Thanks to the sincere cooperation of the owner, design, construction, materials and other teams.
