蒲江观景台丨中国成都丨MVRDV

MVRDV已完成蒲江观景台的建设。这是一处由覆土拱形木结构构成的观景设施，坐落于成都以南的丘陵之中。该项目既是一处游客目的地，也是一处活动空间，充分利用了中国中部地区壮丽的自然景观。建筑在设计上既力图融入自然环境，又希望在山脚平原远望时成为一处清晰可辨的“灯塔”。覆土木拱结构呈现出一种伸缩式的形态，引导访客走向开阔的观景窗与向坡外挑出的观景阳台。

MVRDV has completed construction on the Pujiang Platform, a viewpoint comprising an arched, earth-covered timber pavilion perched among the hills to the south of Chengdu. The project serves as both a visitor destination and an event space that takes advantage of the spectacular natural beauty of central China. Designed to blend into nature while also standing out as a beacon when seen from the plains below, the structure of earth-covered timber arches takes a telescopic shape, drawing visitors to the expansive viewing window and balcony that projects out over the slope.

蒲江新城目前正位于成都西南方向加紧开发中，目标是为居民提供一种高品质、可持续的生活方式。在蒲江以东的丘陵中，原本已有一处简易观景点，可俯瞰正在发展的新城以及其背后的邛崃山脉全景。蒲江县规划和自然资源局委托 MVRDV对该观景点进行升级改造，使其成为具有吸引力的旅游目的地，同时也具备举办从婚礼到政府会议等多种活动的空间能力。

The new town of Pujiang is currently under development to the southwest of Chengdu, with the intention of providing its residents a high-quality, sustainable lifestyle. In the hills to the east of Pujiang, a simple existing viewpoint offered commanding views over the growing town and the panorama of the Qionglai Mountain range behind it. MVRDV was commissioned by Pujiang County Planning and Resources Bureau to upgrade this viewpoint, turning it into a desirable destination for tourists, as well as an event space capable of hosting everything from weddings to government meetings.

MVRDV的设计起点，源于一个重要的发现：原有观景观景台在建设过程中削平了山体。设计通过营造一座覆土的拱形亭体，使其与周围景观融为一体，从而在空间意象上“重塑”了原本存在的山丘形态。同时，设计对场地内的路径系统进行了优化，新增多条通往观景点的线路，其中包括一处嵌入扭转楼梯结构中的次级观景观景台。亭体本身采用木结构建造，作为鼓励中国建筑行业更多采用木材的一种示范——尽管木材在降低碳排放方面具有显著优势，但受制于法规与行业惯性，其在中国的大规模应用仍相对有限。

MVRDV’s design started from the revelation that the hill was flattened during the construction of the pre-existing viewing platform. By creating an arched pavilion covered with an earth berm that blends into the landscape, the design creates an echo of the hill that existed before. The design also improves the path network to add multiple routes to the viewpoint, including by adding a secondary viewing platform incorporated into a twisting staircase structure. The pavilion itself is made using a timber structure, serving as a demonstration to encourage greater adoption of wood in the Chinese construction industry; despite the benefits of wood in reducing the carbon emissions, Chinese regulations and industry at large remain hesitant to adopt the material at scale.

建筑入口位于亭体东南侧覆土坡体中，一处嵌入式的小型玻璃立面标示了进入路径。进入内部后，屋顶向上抬升，而地面则顺着山势向下倾斜，整体空间顺应自然坡度展开。由此形成的阶梯式看台空间，非常适合举办展示活动，或供人们静坐，通过另一端高达10米的玻璃立面欣赏景观。该立面设有一对超尺度的滑动门，可将室内空间完全打开，与外部观景阳台融为一体，使阳台在需要时成为室内空间的自然延伸。

The pavilion is entered via a small glass façade set into the earth berm on the building’s southeast side. Inside, the roof slopes upwards as the floor slopes downward, conforming to the slope of the hill. This slope forms a tribune that is ideal for presentations, or simply for sitting to take in the landscape through the 10-metre-tall glass façade at the other end. This façade incorporates a pair of oversized sliding doors that open the interior to the viewing balcony outside, maximising the connection between inside and out and allowing the balcony to serve as an extension of the indoor space when required.

MVRDV创始合伙人Jacob van Rijs表示：“这一地区的丘陵景观极为壮观，因此我们面临的挑战之一，是在最大化景观体验的同时，尽可能减少对自然环境的影响。通过增加一座具有山丘形态、并覆以绿色屋顶的亭体，我们不仅降低了自身的干预强度，也在空间上重建了原本存在的山体。这种对自然的尊重与保护，正是设计的核心精神，并在建造策略中得以延续——采用木材等生物基材料，使建筑更具可持续性，从而对自然环境造成更小的影响。”

“The hills of this region are truly a spectacular sight, so one of the challenges we faced was to make the most of those views while reducing the impact on the landscape”, says MVRDV founding partner Jacob van Rijs. “By adding a hill-shaped pavilion with a green roof we not only minimise our own impact, but we recreated the hill that was there before. This act of preserving and respecting nature is the essence of the design, which is continued in the construction approach, using bio-based materials such as wood that are more sustainable and thus have less impact on natural environments such as this one.”

项目的景观设计旨在强化场地原有的自然特质。所选植物反映了基地现存的生物多样性特征——包括亭体屋顶覆土坡面，其土层厚度为10厘米，能够支持多种草本植物、花卉及小型灌木的生长。同时，场地内原有的水系被用于雨水收集与灌溉。

The landscape design of the project aims to enhance what already exists at the site. The plants used reflect the site’s current biodiversity – including on the earth berm over the pavilion’s roof which, with a soil depth of 10 centimetres, is capable of hosting a wide variety of grasses, flowers, and small bushes. Meanwhile, existing waterways are used for rainwater collection and irrigation.

设计充分整合了场地内原有的步行路径，并通过新增一处楼梯将其串联成一条环线。楼梯顶部设置了一处圆形次级观景观景台，可360度环视远处群山与近处自然景观。▼路径顺序，Path sequence © MVRDV

The design incorporates the pathways that already existed on the site, adding a staircase to connect them into a loop. Atop the staircase is the circular secondary viewing platform, offering 360-degree views of both the distant mountains as well as the nearby natural environment.

除木结构本身有助于降低建造阶段的隐含碳排放外，项目还整合了多项策略以减少运营能耗。覆土坡体及其植被提供了显著的保温性能与热惰性，有效缓解温度波动；室内天花采用分层构造，以促进自然通风，从而降低室内温度。大型观景窗朝北设置，配合屋檐出挑及周边树木，对较小的入口立面形成遮阳，最大程度减少太阳辐射得热。此外，建筑部分能源需求由地源热泵系统提供。

In addition to the project’s wood structure, which helps to keep its embodied carbon emissions low, the design incorporates a variety of strategies to reduce operational emissions. The earth berm and its greenery provide a significant amount of insulation and thermal mass, reducing the effect of temperature changes, while the ceiling is layered in a way that allows natural ventilation to cool the space. Solar gain is kept to a minimum, thanks to the north-facing orientation of the large window, and the roof overhang and surrounding trees that protect the smaller entrance wall from direct sunlight. Meanwhile, a portion of the pavilion’s energy requirements are provided by a geothermal heat pump.

这些可持续策略确保蒲江观景台充分体现了山脚下新兴可持续城镇的身份特征。无论是当地居民还是游客，在此都能直观感受到一种与自然环境无缝融合的可持续建筑范例。夜晚时分，从观景窗透出的灯光使其成为丘陵中的一盏明灯，从下方平原清晰可见。

These sustainable features ensure the Pujiang Platform reflects the identity of the emerging sustainable town at the foot of the hill. Upon visiting, local residents and tourists alike see a demonstration of sustainable architecture that seamlessly integrates into its natural surroundings, and at night, the light shining from its window turns it into a beacon in the hills, clearly visible from the plains below.
