Thesis Project, Fifth Year Library Excellence Award

Gwanghwamun square, which has historically served as a public and civic space in South Korea, is struggling to meet the diverse demands of citizens in the rapidly evolving urban landscape. The square’s design and limited functionality have hindered its ability to adapt to the changing needs of the people. It has become an extraordinary stage-like space, controlled by a single purpose and thematic changes, rather than a common gathering place for citizens. To address these limitations, there is a need to reconfigure the square or introduce a new type of square that caters to the functional requirements of modern society and fosters harmony among users.

Gwangwha square of 1970, under military dictatorship

After 1960 Korean independence, Gwanghwamun Square, under the military dictatorship regime, became a space where planned government events such as military parades took place. It functioned as a vertical civic space, serving to showcase the strength of the dictator to the citizens and assert its dominance.

Gwangwha square of 2023, after intervention

With the advent of democracy in the 2000s, civic awareness grew in South Korea, leading to discussions about creating horizontal civic spaces. However, there have been persistent challenges by the government and politics. It prevented the square from being ordinary place for every citizen and made it into a political stage. In response, I propose a new square typology.

Undersquare 13 | Cemetery

In the lower sections of the plaza, more subdued emotional programs are situated. At the bottom of the ‘undersquare’, in the cemetery, commemorations for events and figures that citizens wish to remember take place.

UpperSquare 11 | Stage

Conversely, at the very top of the entire section, the ‘uppersquare’ houses spaces for the most open and dynamic, perhaps even bold, programs. For instance, spaces are allocated for programs like protests or performances that cater to a large audience.

ABSTRACT

Since 2000, Gwanghwamun Square has failed becoming and generating a stage for political-crowd chaos, rather being a square for all, has been the chaos itself riding on the conflicts between opposing political forces, which emerged in the wake of the country’s rapid economic development and democratization.

To address this, I reimagined the square by weaving a grid system(vector field) with elevation(gravity, additional function on the field) to examine new typology. Doing so, I explored the idea that when a crowd grows large enough, it moves according to physical laws(advection)* and we can predict its movement.

For this, I organized and modified the Navier-Stokes equations to reflect the influence of elevation(gravity) and crowd density(divergence&pressure) on the flow of particles within the grid.

ORGANIZED CHAOS

The altered topology and the resulting influence of elevation are transformed into a gradation of gravity, which also helps to generate organized chaos within the plane. The scattered spaces and crowds, once caught in a cycle of disorderly collisions and disintegration, now share an organized and segmented yet interconnected space, creating a spatial gradation.

Now, we can enjoy organized flow, which demonstrate organized space with degree of gradation.

Previous square has no intervention or elevation. There is no grid and no rules, only chaos for politics

UPPER SQUARE, BLOCKS, UNDER SQUARE

The new square is divided into above-ground and underground sections. On the surface, along the undulating plane, public programs such as protests take place, while each block in the underground section offers indoor spaces. Spatial connections between ‘Under Square’, ‘Blocks’, and ‘Upper Square’ allow for free movement, and the Upper Square itself creates architectural promenade, connecting all three spaces.

The previous GwangHwa Square was just wide and flat.

The flat GwangHwa Square is excavated underground, and sections are divided according to a grid.

The divided sections are assigned architectural functionalities and programs, with separate masses connected as one long square on the surface.

The upper surfaces of the masses that connect on the surface are adjusted in height at each corner to create distinct square spaces. This design allows users to utilize the same square while experiencing different emotions.

The surface of the ‘Upper Square’ traverses all sections of the entire square sequentially.

The Shali Fortress, once a historic symbol adorned with legends, has lost its former glory, becoming a neglected corner. We aim to rejuvenate it by creating a modern performance space and community hub, leveraging its rich heritage for a sustainable future. Our project bridges the past with progress, honoring Siwa’s essence while building a thriving local community.

Day | Bazaar

At the heart of the Shali Fortress, an amphitheatre takes center stage, transforming into a bustling bazaar(marketplace) for local residents and visitors during non-performance hours.

Night | Amphitheatre

However, as night falls and darkness descends, vibrant lights illuminate the stage, giving captivating performances for the visiting audience. The amphitheatre transformed from community space to a stage, becomes a dynamic cultural and economic hub at the heart of Siwa Oasis.

Library

In the 21st century, amidst the flood of information, people have succumbed to unfiltered, sensational, and instant information, aggravating the information gap. Quality information leaves only limited accessibility. In such an era, a library should be more than just a place for storing and disseminating quality information; it should become a place that ignites intellectual curiosity among ordinary citizens.

4 Entrances, 4 Circulations

It provides a free-flowing circulation from all directions, with a grand entrance and a transparent façade to visually entice users. The ground floor, serving as the user’s initial impression of the space, make people experiences based on different zones and circulations. In the lower levels, easy and quick access to information is available, while as you ascend, more specialized and challenging information, as well as private spaces, are provided.

Floor Plan | 1F, 4F, 5F

As you ascend from the lower levels to the upper levels, the slabs gradually narrow. In the lower levels, easy and enjoyable access to information is provided, along with public spaces. As you move to the upper levels, there are spaces for private activities, and access to specialized knowledge. Physical books are only available on the top floor, the 5th floor.

Through redevelopment near the site, large-scale APT complexes have emerged in DongDaeMun district, forming closed communities in the most expensive area. These complexes restrict external accesses. To create an atmosphere open to all nearby residents, my design involves meticulous manipulation, both in architectural shape and circulation.

Different forms of oversized entrances are installed in each of the four directions (north, south, east, and west), implying pathways that draw people from the outside into the interior.

Logistics movements within the library are handled by robots. People focus solely on coordinating information while all functional aspects are carried out underground by robots and machines.

The transparent façade reveals the internal activities to the outside world in a transparent manner.

Mega Truss with Structural Glazing

The structure of this project utilizes transfer beams, mega truss frame and wire truss structural glazing system to achieve a transparent and uniform façade with narrowing slabs as it goes to higher floors. The entire entrance is designed to function as a vertical structure.

Changsin-dong town in Seoul, known for its clothing downtown manufacturing, is facing industry decline. To intervene, I propose a strategy of collaboration among merchants, young designers, and visitors. This approach will revitalize Changsin-dong, providing an inspiring urban experience.

Vierendeel Truss

Whole building is sustained by 2 stacked vierendeel trusses. It only uses 8 columns through entire structure.

Site Plan | From Horizontal Section | West to East

EPICENTER

as a starting point of regeneration network

The urban regeneration of Changsin-dong flows from the outermost layer of the town towards the inner layers over time. New high-value-added industries are introduced first as an epicenter, serving as the starting point of a network. This network, in turn, creates spaces for existing industries to connect with or generates new spaces for mobile or residential populations. The entire network provides a long urban promenade from the starting point to the heart of the town.

The Global Alliance of Urban Architecture (GAWU) is a consortium of global architectural universities to hold collaborative workshops for discussions on urban architecture. In the workshop held in Singapore in 2022, My team engaged in Design Probe to address climate crisis, rising sea levels, and flood damages.

Singapore is one of the most vulnerable cities in the world to climate change and sea level rising. Bishan Park, Singapore is expected to be submerged below sea level in 2050. Moreover, it is closely connected to residential areas and financial districts. In this context, I propose housing solutions for flood-affected refugees and original residents.

3D Printed Ceiling Module System

First Author, Undergraduate Research Student

Digital fabrication utilizing robots and 3D printing technology is actively progressing. I participated in a research project on ceiling prototyping using FGF (Fused Granular Fabrication) 3D printing technology and presented a paper as the first author, which was selected as an outstanding paper. Additionally, I am currently applying for a patent for the joining hardware components for ceiling module used in the research.

The panels produced using FGF 3D printing went through several design studies, resulting in three types with different thicknesses: 10mm, 30mm, and 50mm. Each type also features distinct internal patterns. As shown above, the 50mm panel is directly connected to the upper structure or frame by wires, while the other panels are all connected using joint components to hang from the 50mm panels.

To create curved surfaces by connecting each panel, a method of adjusting the angles and spacing between them is necessary. Additionally, for the connection joints to maintain a consistent angle and spacing between the panels while withstanding the load, a design was developed using FFF 3D printing to create prototypes for testing. After testing, stainless steel was used to produce the actual fasteners.
