Zhejiang Conservatory of Music, where " Floating Cornice on the Brook” is located, the country's tenth and only newly constructed professional music education college. At the time of the design competition ten years ago, reflecting on the current pattern of conventional enclosed universities surrounded by walls, Zhu Peidong, the Chief Architect, has tried to take "an Open Music Art Park" as a new spatial prototype, and operated in the form of landscape and settlement namely "Flowing Landscape, Hidden Mountain Residence" - the operation of this landscape and settlements – to breaks away from the scale and interface of the traditional university campus to seek a more free and open new spatial prototype of art college construction.

Since the campus was built and put into use in 2015, with the gradual running-in of the campus software and hardware supports, and the improvement of the operation and maintenance management level, the management team of the college decided to declare the whole campus as a 4A cultural tourist attraction. Thus, it provides us with a practice opportunity to continue the original intention of design in the form of campus micro-renewal, and helps the campus to expand its identity connotation from the "open campus" at the design level to the "public scenic spot" at the social and ecological level.

Linear Embedding: North-South Connecting



The layout of campus buildings varies with the land use and is divided into two groups, north and south, with distinct morphological characteristics and distinction. On the north side, it is the natural landscape architecture embedded in the mountain and on the south side,it is the ceremonial space with clear artificial boundaries. The design leaves the middle part blank, connecting the north and south campus groups with flowing curving walkways, meandering channels along the mountain and natural landscape.

As an important infrastructure upgrade for the campus 4A scenic spot evaluation, strengthening the public attributes of the middle section of the campus and activating the existing campus space have become the proposition purpose of our Open-ended micro-renewal.





Through the retrospection of our original design intention at that time, combined with the current new needs of development inside and outside the campus, we finally selected the rainwater garden along the mountain canal in the middle section of the campus, which was originally left blank, and embedded a linear pedestrian system with minimal intervention approach on the site.

Borrowing from the traditional Chinese painting technique of scattered perspective and translating the spatial elements of "Plank, Corridors, Cornice, Bridges" of classical Chinese gardens, we try to superimpose multiple focal points, spatial forms and behavioral scenes in the longitudinal space of Floating Cornice on the Brook, so that people can gain a circuitous and diversified spatial experience and reading perspective when walking and viewing, aiming to activate the existing inefficient vacant space in this section of campus and improve the campus public roaming experience.

On the north side of Floating Cornice on the Brook, the wooden plank path gently floating on the ground is used as the guide, connecting the music department building which fades along the mountain and entwines with the remaining sound; On the south side, it ends with the unilateral cantilevered steel bridge and platform base, facing the campus canteen that linear spread out on the ground. Thus, it has formed the natural walking path at the foot of Wangjiang Mountain, providing a new experience of walking from north to south of the campus through woods and Brooks for teachers and students and visitors.

Parallel Corridors: East-West Dialogue



In the boundary of the campus’ central part of, the newly-built Floating Cornice on the Brook and the Cloud Corridor in the Valley of Music, which has been in use for many years, are parallel, integrating into the natural mountain scenery in the middle of the campus, forming a campus public space system that can induce diversified daily behaviors. Ten years ago, Cloud Corridor in the Valley of Music was designed in accordance with the overall concept of the campus, emphasizing the design entry point of soft curves and flowing landscape. The solid volume of fair-faced concrete contains the delicate texture shaping by board grain, and at present constitutes the established design basis for our campus micro-renewal.




The new steel and wood folding corridor Floating Cornice on the Brook on the east side and concrete corridor Cloud Corridor in the Valley of Music on the west side are added. One is light and the other is heavy, one is virtual and the other is real, one is folding and bending, one is soft and the other is rigid. They connect the north and south of the campus in different ways, and form a dialogue spanning over a decade in the form and topography, structure and materials of each other. They form the hidden boundary of Zhejiang Conservatory of Music facing the Natural Mountain and gentle slope landform in the middle. In the corridor, in line with the flowing space structure of the campus, the landscape presents a geometric linear shape. The landscape road and corridor are like melody and notes, guiding the crowd to move dynamically across the campus.

Crossing the Brook and through the Trees / Meandering along the campus boundary


Cloud Corridor in the Valley of Music forms barrier blocking the noise with half-open fair-faced concrete corridor, while the Floating Cornice on the Brook leads the mountain into the garden with fully transparent steel and wood folding corridor. The concrete corridor curve is soft and steel and wood folding corridor twists and turns with distinct nodes. The corridor of the two materials follows their own terrain characteristics to interpret the two forms of the corridor.

There is a height difference of 1 to 4 meters on the east and west sides of the original site of Cloud Corridor in the Valley of Music, and the outer side is the campus and the urban roadway. Compared with the monotonous retaining wall, the semi-arch wind and rain corridor cantilevered continuously not only eliminates the interference of traffic noise, but also poetically builds a traffic space to overlook the distant scenery of mountains and shelter the wind and rain. The roof is then covered with soil to blend into the landscape, softening the eastern boundary of the campus. The micro-renewal design implemented by line+ preserves the original spatial design relationships and landscape texture replaces the original landscape plants by a cherry grove consist of 33 early cherry trees.

Looking west along the Cloud Corridor in the Valley of Music, there is Wangjiang Mountain. At its feet, the Floating Cornice on the Brook along the mountain edge, zigzagging forward across the Brook, compound by the spatial elements of "Plank, Corridors, Cornice, Bridge", and integrating the behavioral scenes carried by walking along the mountain, paly with water, walking along the brook and winding paths, creating a multiple and composite spatial experience path.


 


Plank: In order to avoid the disturbance to the original environment of the site, the folding corridor is elevated above the brook, as close to the water as possible, avoiding the native trees in each folding, and fitting the trend of the mountain.





Corridor: roof float on and columns stand on the plank to form a corridor, which bends in accordance with the trend of the mountain edge and the bank, folds middle part into the brook for pedestrians take several steps to sit next the brook. Corridor integrate the functions of sitting, watching and strolling, which creating a shared leisure place.

Cornice: simplify the traditional sloped roof ridge and eaves, smooth the slope difference of double-sloped roof, so that Cornice appears light and unobtrusive. The Cornice are twisted and folded on the Plank to form a bench for lounging and a buttress that defines the beginning and the ends.

Void and Solid / Hardness with Softnes



The roof structure of Floating Cornice on the Brook is a box-shaped beam with an I-shaped beam and the roof is an abstract form of double slope and four-corner polygonal roof. Corresponding to the four corners polygonal roof, the ceiling forms an inverted pyramid. All the fulcrum points converge at the apex of the pyramid, so that the roof which is north-south length of 113 meters is supported on the ground by only five slender steel columns. Vertical structural members are thus minimized use.

Viewed from the far side of Cloud Corridor in the Valley of Music, the steel column of Floating Cornice on the Brook looks like a tree trunk. The horizontal member Cornice thus becomes the visual focus, presenting the effect of Cornice overhanging over the Brook, and realizing the integration with the surrounding landscape.

At night, the lamp belt is lit, and the ceiling and column are like umbrella frames. Lights on the roof outline the path of people.





In contrast to the void presented by integration with the surrounding landscape, Cloud Corridor in the Valley of Music uses solid materials as a screen and satisfies the functional premise of sound blocking and soil retaining. Meanwhile, following the vertical height difference on both sides, the construction is adapted to local conditions. The special-shaped fair-face concrete is designed with multiple controlled curvature segments and 600 sections with acoustic gain performance to form a soft and continuous single-arm cantilever structure by setting out each half meter in sections.

The operation and maintenance of the campus have become normal after years of use. In order to reduce the interference of construction behavior to the campus teachers and students, the construction of the Floating Cornice on the Brook was carried out in summer vacation. During the construction process, the main components of the steel structure were prefabricated in the factory and then transported to the site in sections for assembly, which has shortened the construction period and ensured better accuracy. Clear fold line joints and segmental assembled prefabricated steel structure make Floating Cornice on the Brook show a state of hardness, and forms a void and solid comparison as well as couple hardness with softness.






|  2.3 Mapping of Materials  |

Warm and Cold/Outside and Inside


In terms of materials, the Cloud Corridor in the Valley of Music of fair-faced concrete presents stronger spatial tension. In contrast, because of its smaller scale and fit to the mountain, the Floating Cornice on the Brook adopts more natural timber to build, and the spatial is comfortable and relaxed for pedestrians.

In contrast to Floating Cornice on the Brook is the implicit expression of the timber in the inner wall of the Cloud Corridor in the Valley of Music. The formwork frame of the flow curve and irregular structure of the supporting concrete corridor is composed of 80mm fir board and bamboo plywood board. The timber transfer texture refines the large screen seems as clouds and waves into a tactile intimacy scale and shelter of rustic sense. From the outside to the inside, the Cloud Corridor in the Valley of Music sets each other off with the real wood grain texture of the steel wood folding corridor.

Floating Cornice on the Brook uses wood to convey two forms of expression of a single material. The dark burnt fir board is used for the roof covering and seats, which is resistant to natural corrosion and hidden the folding corridor in the woods. The ceiling and corridor buttress are made of primary red cedar wood, presenting natural color. Inside the corridor, pedestrians are accommodated with warm texture.





As the sun sets, the primary red board cedar ceiling reflects the light and shadow of the brook. At this time, the folding corridor is a comfortable and relaxed leisure space, where people lean on the fence to watch the fish, pick up the steps and sit and leisurely stroll. Floating Cornice on the Brook are extended in a friendly manner, guiding people inside and outside the school to participate in artistic activities.

Eco-Friendly: Sponge Landscapes



As an important node of the ecological axis of the campus, Floating Cornice on the Brook, with the concept of rain gardens and minimal intervention on the site, the native campus water system, trees and grasses are preserved and incorporated into the design of the space, trying to build a campus sponge landscape that combines ecological sustainability with landscape art and behavior participation.




△ Surface runoff into the brook



There is a natural transition between the Brook and the traffic and pedestrian roads in the middle of the campus as well as the Cloud Corridor in the Valley of Music through the lawn buffer zone, bush buffer zone and the brook landscape belt. Combined with the design of the corridor without contact with water, the natural gentle slope on both sides of the corridor enters the water by steps on brook bank without disturbing the growth of aquatic plants. Through the comprehensive purification of plants and sand, the water quality of natural precipitation can be improved, and the water gradually infiltrated into the soil to conserve groundwater and supply landscape water.

New Chapters of Old Songs: Campus open to public




Floating Cornice on the Brook is a freedom and openness public space was built for Zhejiang Conservatory of Music, which re-envision the campus' construction that was completed several years ago. Floating Cornice on the Brook serves teachers and students with the improved campus infrastructure, and integrates natural resources and seasonal landscape scenes to benefit the public. With new forms, structures and materials, it forms an interesting east-west dialogue with the original Cloud Corridor in the Valley of Music, completes the linear open space in the middle of the campus, and connects the buildings in the north and south areas. Thus, a public culture and art space that is open and shared with the city and permeated with the nature is formed.





Being open for use over the years, Zhejiang Conservatory of Music has held many national and provincial music and art activities for the public. Within the macro scale of the art park, Floating Cornice on the Brook improves the campus infrastructure and artificial ecological environment by constructing a natural rhythmic walking corridor, benefiting various public groups. In the microscopic scale of regional ecology, it is a rest space based on biodiversity.




As the poem says: "Nature is full of the image of time, nature stays, and time flies, all from the perfect; So the light from above shines on mankind like the flowers near the trees."
