Construction Starts in Hangzhou Phoenix Valley Cultural and Creative Park

Y-Shaped Valley

Y 谷聚落



lMeng Fanhao, co-founder and chief architect of line+ studio, won the design rights for XTGroup's first project, the Phoenix Valley Cultural and Creative Headquarters Park. Meng Fanhao is the project's principal architect and lead designer, responsible for the collaborative work of architecture, interior, landscape, curtain wall, and lighting of the project, as well as managing the full process from idea to realization.


The project is in Hangzhou's southern hinterland, namely in the Phoenix Valley. Following the settlement prototype, line+ investigates new possibilities for open and mixed-use blocks within the context of the natural mountain valley environment and urban growth patterns. The project is currently under construction.





“在杭州这片得天独厚的绿色山谷间,八座单体建筑以Y型作为原型母题,顺应地形山势,散落生长为一个有机聚落,探寻人工与自然之间新的平衡点。”

挑战

Challenges

The enchanting aspect of Hangzhou lies in the dynamic relationship between its urban and natural structures, and the Phoenix Valley, located in the southern hinterland of the city, vividly showcases the distinctive characteristics of Hangzhou's nature and culture. In the previous era, the Phoenix Valley unit was seen as an object for resource extraction. Even today, traces of its past as a mining site can still be discerned from satellite images, and the surrounding mountains seem to have been preserved like "fingertips."

With the development of the city, the Phoenix Valley unit has gradually transitioned from the urban periphery to the urban core. The former cement factory has been transformed into an art creative park, hosting prestigious art institutions such as the China Academy of Art and Zhejiang Conservatory of Music. Leveraging the unique natural landscape and cultural artistic resources in the region, the government and investment companies aim to construct a headquarters park themed around art and creativity, attracting top creative and artistic companies to establish their presence.

In the evolution of spatial history, the paradigm shift from "mining-factory" to "landscape-art" signifies a transformation in the relationship between "nature" and "urban." Addressing this change and establishing a connection between nature and the city, as well as the past and the future, becomes a paramount concern.



Specifically for the site, the design needs to arrange eight independent buildings on this triangular plot with a maximum height difference exceeding 10 meters and limited space. Another major challenge in the design is how to minimize negative space and enhance land utilization in this irregularly shaped plot.



As a headquarters park, the buildings have placed extremely high demands on both commercial value representation and internal space quality. While meeting the basic conditions of good lighting, ventilation, and clear office space, there is a need to create as many diverse leisure spaces as possible. Simultaneously, the design must adapt to future trends in more personalized office environments.

原型

Prototype

The planned land has a southeast side length of approximately 140 meters, a southwest side length of about 270 meters, and a north side length of about 230 meters, forming a triangular shape.

On one hand, we aim for the architecture to restore the original form of the mountain, serving as a retrospective of historical memory and reflecting the architect's approach to intervening in nature. On the other hand, for practical functional considerations, we hope the architecture still maintains the basic geometric characteristics of modern architecture.


Based on these fundamental value judgments and after multiple rounds of scheme comparisons, we finally found the architectural form that best suits the site – filling the natural landscape with a branching Y shape.

Unlike the 90° square box, the 120° form demonstrates better adaptability to complex terrain. The strip units, compared to block units, can better fill the triangular space and reduce negative spaces between the site's edges and the buildings.

Considering the relationship between the site and city roads, the northeast side of the site serves as both the main pedestrian entrance to the park and a crucial route to enter the larger-scale Phoenix Valley Art and Creativity Zone. The Y-shaped form at the entrance confronts at an angle, on one hand, making way for the pedestrian entrance plaza, and on the other hand, combining with the elevation difference to create an entrance space with tension.



The design involves rotating two buildings in the central part of the site and utilizing the terrain to create a coherent and flowing internal public space. This ensures that the internal square meets both the public needs with sufficient scale and provides a naturally appealing and spacious environment.



A strip of public space runs through the site, connecting the east and west pedestrian entrances, resolving the elevation differences between different terraced levels. It extends in various directions, interconnecting the eight standalone buildings.


On the north side and southeast side, there are five five-story buildings each. On the southwest side, there are three buildings: one four-story building from north to south, followed by two three-story buildings. This overall layout conforms to the natural form of higher elevation in the north and lower in the south, aligning with the sunlight conditions of higher elevation in the north.

△ Terrain Elevation Analysis



Located in the canyon, the site boasts excellent views in various directions. Therefore, the buildings step back as much as possible in different directions, ensuring that each level has an outdoor terrace to provide good outdoor recreational spaces. The rooftop garden design takes equipment into consideration, using partition walls to define activity spaces and equipment placement areas, increasing the utilization of rooftop space, and simultaneously considering the building's fifth facade.


△  Individual Building Generation Diagram



In the interior design, we break down the Y-shape into a series of square spaces. First, through the rational layout of the core, we eliminate negative spaces generated by the form's turns, making the internal space completed, coherent, and full of richness and fluidity. We tailor the office environment and personalized display space to match the corporate temperament and brand tone.

立面

Facade

The façade language extends the symbiotic relationship between the city and nature, harmonizing organic architectural forms through a more concise and modern formal language to achieve a balance between urban and natural elements. This also implies that the occupying enterprises can simultaneously enjoy the wild charm of nature and the refined lifestyle of the city.

The architectural façade follows the logic of the form design, distinguishing between the lateral and end sections of the Y-shape through two design languages. The lateral side emphasizes the natural extension of the Y-shape through continuous horizontal lines. The end sections maximize glass areas to emphasize the abundant panoramic views.

结语

Conclusion

About how the city and nature coexist, Hangzhou has provided numerous wonderful answers. In the Phoenix Valley, line+ takes the settlement prototype as its consideration, envisioning a positive interaction between office and natural scenes. Just as the scars of factories and mountains declare the cognition of the past era, the new branch-like buildings will open a fresh chapter for the future.
