Project description

This project is situated within the heart of Edinburgh’s city center, in Prince Street Garden. It comprises a bridge spanning north to south across Prince Street Garden, with its southern end nestled at the foot of Castle Rock and its northern end connecting to a garden promenade parallel to Prince Street. This bridge serves not only as a thoroughfare linking the city’s two ends but also as an architectural endeavor that integrates considerations from multiple fields including botany, art, and ecology.

“Seeding Architecture”

Symbolising the concept of seeding architecture, this bridge aims to blend nature seamlessly with urban environments. Its southern end adjacent to Castle Rock and its northern end connecting to the garden promenade parallel to Prince Street draws inspiration from Geddes Gardens flanking both sides of the Royal Mile. These gardens are seen as seeds of natural environments planted within urban settings. Part of the space on the bridge inherits the metaphor of seeds in form and constitutes a dual narrative of seeding with its function as a botanical laboratory: On the eastern side of the bridge, a series of vessel structures serve as exhibition halls, showcasing achievements in botany and themed tea room/shop. These suspended vessels complement the cabins on the other side of the bridge. These cabins provide researchers with lab space to explore and study the world of plants.

The form of the bridge harmonizes with its surroundings, with its crane structure not only providing visual dynamism but also hinting at the close relationship between research and exhibition, urbanity and ecology. It resembles a painting floating in the wind, illustrating the symbiotic relationship between ecology and humanity.

Site Plan with Bridge
Concept Generation

This project began with a study of the historical patterns of Edinburgh’s urban development, culminating in the creation of charts depicting the changes in urban and natural (rural) areas.

The Royal Mile is Edinburgh’s first street. In the 15th century, market activities were permitted by the royal family, leading to the gradual development of markets and streets on both sides. The city began to expand to the north and south of the Royal Mile.

Following the Industrial Revolution, increased productivity and the construction of the North Bridge accelerated urban development. The city’s footprint expanded further, with the former Nor Loch drying up and green spaces being enveloped by the urban environment.

Later, Patrick Geddes advocated for the clearance of dangerous buildings and ruins amidst the dense housing on both sides of the Royal Mile. These cleared areas were termed Geddes Gardens. Given its significant reversal trend in the charts, I hoped to gain inspiration for eco-friendly architecture by focusing on the form of Geddes Gardens depicted in the diagrams.

Urban History Study
From Gardens to Vessels

From the Royal Mile to the North Bridge, urban expansion has always been accompanied by the construction of roads. Simmel calls the building of bridges the culmination of the act of building roads. Inspired by my study of urban development, I began to focus on the Royal Mile, particularly its relationship with Geddes Garden. I see these gardens as natural seeds sown in an urban environment. Initially, I brought the relationship between Geddes garden and royal miles into the form of a bridge. The idea of attaching volumes on both sides of the bridge is clear from these two models from early in the project.

In addition to the metaphor of seeds, Geddes garden is also similar to vases. which means natural plants surrounded by an artificial wall. By seeing the Geddes garden as individual vases, I am reminded of the paintings of Giorgio Morandi. 

 

While exploring the relationship between wind and architecture, an axonometric aerial view from the north of the site to the south was discovered. The bridge, Prince Street Garden, and Castle Rock are combined in a very similar way to the Japanese painting "Fuji Mandara." This painting depicts the trajectories of people climbing Mount Fuji and the airflow flowing through it, which resemble the bridge form and contour lines of this site. Air currents and cloud forms from the painting were used. The relationships between roads, houses, wind, people, and the natural environment were extracted from the paintings. Colours were then used to distinguish human activity sites, houses, and people’s actions, and these resulting colour blocks were placed into an axonometric drawing. Through imagination, the general direction of the laboratory space was obtained.

The idea for the final design came from a combination of all the conceptual explorations attempted during the semester. On top of these patterns that exploit the specific shapes and textures of Morandi’s vessels, I layered the architectural language derived from Fuji Mandara. These two aspects of exploration culminated in two elements of the final building: the rounded vessels on the east side of the bridge and the hard lines of the laboratory section on the west side of the bridge.

Reflective Statement

The course handbook suggests that in the current era, the focus may be more on the "consequences" rather than the causes of architectural forms. This implies that, from a design generation perspective, emphasis should be placed on the materiality, construction, and usage of buildings, rather than on abstractly generating architectural forms.

In this course, the unit approached construction in a more poetic manner. The last four stanzas of Philip Larkin’s poem "Bridge for the Living" cleverly convey a sense of something being constructed and experienced within us, representing a constructive and poetic construction. To achieve this, a series of factors were intertwined, shaping the final proposal’s construction logic, poetic combinations, and procedural space. This approach led to an enhanced understanding (or dialogue) between ecology and urbanism. Unlike the more straightforward description in the handbook, there exists a poetic ambiguity here. Although it begins abstractly, it genuinely concerns the consequences of the environment and architecture.

The ambition of this project was to address this issue from both poetic and scientific perspectives. Through previous learning and practice, it became clear that environmental conservation is central to the architectural industry, with emphasis on material usage and energy efficiency. This is reflected in environmental accounting methods like carbon footprints, material energy consumption, and lifecycle assessments such as LCA, LEED, and LBC. However, Braham in "Environments of Maximum Power" points out that these energy accounting forms are insufficient to provide a new ecological architectural form for the new century, as they fail to fully understand the operation of ecological systems. Additionally, it was observed that mandatory regulations often lead to mechanistic thinking, simplifying the pursuit of environmental sustainability into specific paradigms or data metrics. This approach risks entangling ecological architecture in scientific determinism.

This implies, to some extent, abandoning skill. As Gaston Bachelard declares in "The Poetics of Space," skilllessness is not a form of ignorance, but a difficult transcendence of knowledge. The greatest takeaway from the course is the ability to utilize "skilllessness" – deriving architectural forms from poetic ambiguity. However, the poetic elements in this context are definite, primarily the concern for environmental issues. Deriving architectural forms from these seemingly unrelated concepts requires a metaphysical bridge. Thomas Harrison suggests that standing on a bridge is like standing on uncertain ground, suspended between two places. Ultimately, exploring the tectonic requires determining how the bridge is suspended and its connection with the ground. This means that through exploration and design, a bridge was ultimately found from the concept of environmental issues to actual architecture. It is important to note that this process does not mean abandoning science but rather attempting to find a parallel route alongside it.

Phenomenological knowledge was incorporated into the design, specifically addressing environmental concerns not only on the ecological engineering level but also from a spiritual level. By combining poetics, an interaction between architects and building users was pursued, making buildings closer to poetry. If buildings are retold in usage like poetry, the purpose of intersubjective communication can be achieved, thus allowing concerns for the environment to be communicated through architectural forms.
