UPSIDE DOWN Location Date Typology Project Position

Seoul, Korea Jun. 2015 - Aug. 2015 Housing Complex Teamwork Team Leader

The project "Upside Down" starts from the idea of finding and creating the hidden spaces without using additional lands, which are the main constraints of the site. From the simple and intuitive imagination, this project is able to provide sufficient area for the recess of the selected people, the residents, and provide a lively regional atmosphere to all the people who visit this site.

The given site "Gingorang Gil(Long Gorge Street)" is a cramped residential district. It is encompassed by mountains, located far from urban amenities and infrastructure. Also, there are scant public spaces for people. Generally, the town has a depressing atmosphere.

Cut and Reverse

Necessary Urban Context near the Site Design Concept

Too narrow spaces in existing condition

Cut the blocks and expanding intervals

Reverse half of the blocks onto the sky

Space for Residents Only

Safe Communication

Entirely Physical Contact

By reversing some masses in the same district, hidden spaces between the volumes above and below appear. The specific physical characteristics of these spaces can provide a variety of activities for residents and visitors. 02

Share Lives through Spaces The whole upper part of the project is provided for residents only. In this space, residents can interact among themselves in various spaces including a rooftop garden, open spaces between each unit, and access space to buffer spaces. By doing so, they can solve the isolation problems.

Nakwon commercial complex is famous because it is one of the first-generation modern architecture in Korea. This building is taken care of as a public heritage designated by the Seoul city government. However, due to its extremely big-scaled planning, it has some problems in the urban aspect. Hence, this project suggests the proper shape of this building to remain and develop more to be used in the future.

Materials and Construction Proposals By using various types of material contents, the project finds proper stuff according to the programs contained in the masses. Also, through these materials, it can blend well into the regional contexts. By reproducing the detail models for parts of the building, the real construction methods for the facade are studied. The joint details of mullions and glass, hanging parts of the metal panels onto the concrete walls are suggested.

THE URBAN CRADLE Location Date Typology Project Instructor

Seoul, Korea Sep. 2016 - Dec. 2016 Library & Cultural Complex Graduation Project Youngho Yeo, Minwha Lee

The project "The Urban Cradle" tries empirical approaches from the research data of the site. By applying architectural and spatial manipulation, its purpose is to suggest that different spatial quality could influence on people's perception and the reaction of the region and their lifestyles. Different scale of space can mediate the atmosphere prevalent in the area, and revitalize the urban functionality.

Interact with the Site This project is focused on the practical approach and solutions for the problems in the selected site. The site's negative mood from the illegal housing and landfill can be purified by nature, Yangjae stream and Dal-Teo hill park nearby the site. Also, there are a lot of schools, but supporting urban facilities are too scant. To provide enhanced quality of life quality, a cultural complex including a library is suitable for the site to achieve the goal.

2 1. Originally the site is the core of contamination of the urban atmosphere in this region because of negative elements. 2. C o n s i d e r i n g t h e s u r r o u n d i n g e n v i r o n m e n t s , t h e s i t e w i l l b e c h a n g e d t o b i g - s c a l e d i n v i g o ra t i n g p r o g ra m s . 3. A big-scaled space overwhelms the surrounding moods with its own vitality, and it spreads positive effects to nearby regions.

Transformed to Embrace the Region Started from the huge volumes as big as possible, the chunk is carefully carved by the influence of the surrounding conditions. It dominates the regions, but at the same time, it considers them. By adjusting properly to the environment, it reduces disharmony with others and smoothly permeates into the townscape.

Monolithic Volume big as possible

Manipulation of mass to be accessible

Penetrate volumes to connect

Connect each all spaces in function

Connect mass in forms read as one

Elevate one side to conform to contour

As a result of the design process, a rough model of building form was accomplished. Conforming to the site boundary horizontally, and looking like a hill vertically, it can perfectly be projected to the site.

Overwhelm the Regional Atmosphere by Scale A huge single mass compared to the residential buildings dominates the regional atmosphere. Also, the position of the site as an intersection of natural resources and social territory makes the function of the project more important. In this plan, we can see that proper indoor and outdoor spaces on the site are located properly and interact vigorously with each other to evoke a positive mood around the region.

SPATIAL JOURNEY Location Date Typology Project Position

Favignana, Italy Jan. 2018 - Apr. 2018 Art Museum & Cultural Complex Experimental Project Individual Project

The site is an archaeological remain with a long history in Favignana, Italy. It has become silent and useless as time has gone by. This project, hence, tries to reuse the site and heritages proper to contemporary usage by suggesting new architectural programs around the ruins. Consequently, it can attract visitors from the outside, so that establishes the foundation for the prosperity of the Favignana region.

Integration of Two Strokes N

The First linear element found from the site is the entrance trail from the road. It is as long as 1.5 km, and ascending slope to the destination. It seems as it needs to be changed interestingly so that visitors can easily approach without feeling bored or tired.

The existing Condition of the walls is almost demolished, and there is just a trace of the location. They can emphasize the castle and provide new forms of spaces to visitors when properly restored and transformed.

Long path + Linear Walls = Continuously transforming spaces

By folding and bending the linear paper, lots of studies for spaces made from paths have been done.

Human experiences different spatial quality at or in the different forms of spaces.

What if these various forms are sequential?

From the entrance to exit, the section of the moment varies subsequently, and that makes it be a unique space. 21

From Line to Space

Wall Restoration

From linear elements, path and walls, it starts transformation by folding or bending to divide and differentiate the space.

Layer Expansion

As developed further, some parts of the walls become roofs and cover the space, but attach onto the outside environment. People could feel it is a different space but not perfectly isolated.

Mass Allocation

Finally, mutated walls encircle the whole space and absolutely segregate the spaces from the surroundings.

Form Transformation

Through various section studies, people can feel the space as distorted passage like the photos left. This kind of space makes people feel soaked into space, and this feeling makes people move, and flow all over the site. Information Center

Currently, this area has remained a s a r u i n o f t h e q u a r r y. T h e attractive point of the site is that it is an empty space in urban contexts of Seoul, and it has a potential to be a breathing part of stuffy downtown environment. Therefore, the project suggests a proper program acting as a key role necessary in the urban contexts, and also in the aspect of architecture and environment, it can provide a fresh space to visitors.

Elements for Emptying the City The site has been used for a quarry to supply the rocks to Seoul for a long time. After closing the quarry, it was abandoned and remained as a ruined place. However, due to this reason, it becomes one of a few empty spaces in compacted urban contexts of Seoul. This project caught the characteristics of the site, so it tried to make a void for the breathing of the city by using proper programs for hollow spaces.

Traffic Volume over Time

Ratio Between Transportation and Population

Destination from each Terminal

Originally traffic density is concentrated to Seoul-Busan Express Way. However, the new construction of the expressway penetrating the site, the traffic density over Seoul can be disseminated. By surveying the overall condition of traffic and population, this project assures the feasibility of the terminal program in the site. By suggesting the terminal program in the site, the project can do a significant role of emptying the traffic in a dense area.

Provide the space to People In addition to suggest a terminal program as a functional role in the city, space itself is fascinating enough for people to enjoy the urban contexts. To provide the space to citizens, the project considers the leisure and cultural programs combined with the terminal functionality. In this process, sociogeographical condition and functional aspects are carefully considered to make the volumes proper to the site.

Cultural Contexts in the cave, Trace of the Quarry

At the western side of the quarry, the quarry cliff itself becomes a big screen for various performances. The internal space of the quarry mountain becomes the cave. In this space, gallery and library programs are arranged according to the spatial characteristics that there are quiet and isolated from the disturbing exterior environment. on the other end of the cave, the trails attached on the cliff wall continue, consecutively provide the exotic spatial quality to the visitors.

It makes a clear and opened view of the western part seen from the top of the eastern deck. The combination of terminal buildings of low-height and the quarry facade creates a distinctive and different image from the ordinary urban fabric and even looks like an eco-friendly environment. At night, the large face of the quarry facade becomes a screen, and many lights of various colors, forms, and intensities brighten the site, and it becomes from abandoned ruins to human-friendly space.

Eastern Performance Stage

The newly planned waterfront park can convert the sterile and kinetic atmosphere in the site to more static and comfortable for people to enjoy and stay there. Adding to this, the floating pedestrian deck lowers the vehicular hierarchy, and change the space more human-friendly. Also, the deck controls the limit height of artificial edifices to provide a clear view and vacant spaces for the city.

Based on the development plan in this region, this project is going to propose the future of the International Boulevard, Oakland. It is currently a soundless, desolate, and especially car-oriented, not walkable place. The project is started from the positive collision between the culture and urban fabric possible to happen in this area. From this proposal, it could be changed to a vigorous and ped-friendly region, and it will become the most popular area in Southern Oakland.

The Collision Component in the Current Area The development plan of the City of Oakland is that there will be a BRT system constructed in Oakland, and there is one of the stations in the site boundary. Starting from this point, supposing that the traffic amount and crowdedness would be increased, the possible collision typologies were analyzed. Especially, the project focused on intersections. Plenty of movement from various causes meet at the intersection points, and interestingly, the site has 5 intersections which have their own characteristics.

Starting from the conceptual ideas, diverse methodologies were drawn in typical three categories: physical environment, programs, and flow. Each category defines the form, system, and movement of the urban fabric in this area. In order to make this region a self-sustaining district, the design concept is to integrate the overall things for people to live with, from the fundamental infrastructure to industry and supply.

Urban: Collision Controls the City From the BRT Station, the crowded and vigorous spaces are becoming silent and peaceful moving toward the north-western side. The amount of movements and frequency of collision is decreased, automatically it makes the town livable and stable. Industry programs are located along the Bart highway line so that they can be a buffer area from the residential area and traffic territory.

Architecture: Movement Makes a Walkable Area The site is especially concentrated on the auto-related industry. To make a walkable environment without removing the current industry, this project plans to concentrate the auto-based programs into a huge building and return the spaces being empty to the communal society. By using various typologies of movement, space is created from the circulation.

Architecture: Movement Makes the Space The movement of cars and people carve the mass to make an overall form of the building. The circulation of each movement makes a repetitive loop inside the building and the chunks remained after being carved become a space of each program at the proper location.

The region for the pedestrian and vehicles are divided by the project. Each group has its circulation route, and the paths make the void space inside the huge chunk. The intersection point in which the pedestrian and vehicles are meeting makes a big void space to provide the users spatial openness and light. Through this project, the building is no more just one building, and it becomes the aggregation of chunks.

OPEN YONGSAN Location Seoul, Korea Date May. 2019 - Jun. 2019 Typology Urban Design Approach with Renovation Project Cultural Revival of the Old National Security Agency Building in Seoul Position Design Coordinator

The city of Yongsan has a piece of a painful history. Hidden from the railway and a bunch of huge buildings, there is a small space used in a secret by the government of Korea. Today, introspecting the past brutality, the city is trying to renovate the building and open it to the public. Approaching from the urban perspective, space can embrace the public more easily with the commemoration of its past.

The Place in Veil The current condition of the site is enclosed by huge urban infrastructures. Because of the site condition, it has previously been operated in a secret. The building was also designed as if it has some sensitive secrets hidden from the normal sections of the building.

HIDING THE SITE

The building has been used for the inspection of anticommunist. It shows the modern history of Korea directly. The other floors were used as a normal government office, but exceptionally the 5th floor was used for the inspection to get a confession from the suspect. However, it was used as a site of torture to get false statements from innocent people.

The interior part would be renovated to be used as a commemorative space. Various walkable programs would be added next to the building for many people to visit and stay. Cars would be separated into the underground for a ground space to be a walkable space.

The parts of the fence at the eastern side would be removed, for the public to access easily. A new exit of the subway station would be added to enhance the accessibility Vehicular circulation would be restricted to make a walkable community The first-floor lobby space of huge buildings facing the main road would be opened to the public.

The railway in the west would become a park since the railway would be put into the basement. The pedestrian overpass would be constructed in the east to connect the urban fabric. Various tourist attractions would be connected by the tourist bus tour route. By doing so, the City of Yongsan can be returned to the public with the memory of the past.
