FORM

The project "Life Hub" is proposed in the closed train station to solve the social problem around and physical isolation of the site. The site is in Oakland, near the area previously used for industrial factories and storages. The city governmenet has a big plan to improve this site, and some of them are already under construction to make the residential districts, but the region does not have social infrastructure and physical connection close to the public. By suggesting community programs together with the massive transportation hub, this project can revive the original function of the existing structure, and at the same time it will be open to the public to enhance the community-friendly atmosphere.

Life Hub

An old train station which is not used anymore is currently located in the western part of the site.

As one of the design strategies of the renovation project, the volume is derived from the existing structure. Especially, the cut railroad on the second floor is reconstructed to be extended to, and connected with the volume newly suggested.

Since the main program of the station was on the 2nd floor, the added massing looks it is suspended by a huge structure to continue the property, reminding a tunnelvv. By doing so, the ground floor is fully opened to the public, making it easy to access and pass through.

The building consists of two different spatial types; the pedestrian, and the vehicular. There is a bus parking lot and mechanics udner the vehicular massings to support the public transportation programs. On the other hand, the pedestrian massing floating a little bit lower than the vehicular is provided for the community, which contains the community-supportive programs and the ground level is entirely open to the public for the local events and leisure place for the community.

The main communal space is the intersection parr of the two massings, open to the sky and most people using this structure are encountering. Every space is connected to this location, so this place functions as a pivot point of the whole space and gathering space for visitors.

The project "The Urban Cradle" tries empirical approaches from the research data of the site. By applying architectural and spatial manipulation, it suggests 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.

Academic Work 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. By using the same method of dealing with the scale of the space, various spatial applications are possible. Overall, there are three representative spaces to be emphasized.

Balcony Blocks the hot sunlight

The shape of a housing unit is derived from the analysis of sunlight in a planaer and sectional consideration. The outer walls of the unit are slightly tilted for th sake of increasing as much sunlight penetrating the massing as possible.

According to the information from sectional analyses, the shape and angle of the balcony are designed to let the proper amount of sunlight into the room in accordance with the seasons, and at the same time drop the maximum amount of sunlight into the sunken space.

The site is carved using various methodologies to get the enough sunlight into the underground space, and a linear park is connecting the north and south on the ground level for sake of the convenience of the pedestrians.

In order to solve the social problems of a lack of residential space, the housing units are staggered from undgerground level to the upper level above the ground, and public programs are mostly located underground so that this sunken space can be activated by passers-by and visitors and well harmonized with the underground housing programs.

By proposing the potential of living underground, this project can make a first step of the new lifestyles and culture of citizens in the future.

Housing Unit Above Ground To assist in solving the lack of housing units problem in the urban area, some units are stacked toward the sky, keeping the design idea.

Rooftop Walkloop with Greenery Consisting of the roof structure from the housing units underground, the linear park with ample greenery can provide a pleasant space to the citizens for leisure, and at the same time give them the shortcut path from the north to the south.

Staggered Housing Underground The housing units underground are arranged in a linear order to maximize the sunlight they can get. Also, the units are stacked obliquely in a vertical direction to minimize blocking the sunlight toward the lowest level.

Carved Ground with Public Space Considering both maximizing the amount of the sunlight and the area of usable space underground, the ground is carved in a slope. most space underground is occupied by public and commercial programs which does not need a lot of sunlight.

The Collision

The form-finding process is started from the analysis of various circulation expected to be occurring in the site. The pink line, which represents the vehicular circulation, starts from the south western point, the bottom part of the picture, and repeatedely turns the point of the site.

As the same methodology, the pathway of the visitors from outside indicated with blue lines and residents with yellow lines are intertwining in the site.

This structure systems gets along with various circulations and space to make the integrated organization of cultural complex with necessary urban infrastructure to provide the goodquality service to the residents and visitors.

Concept & Form Finding

Secondly, the circulation is categorized overally into twy types; the vehicular, and the pedestrians. The pink one infers the region provided to the machines, and the blue area is decorated for the people. Except the entrance, the vehicles are rotating inside the deep part of the massings, and the people's zone is encompassing the vehicular's for the sake of safety and pleasant environment to hover over.

Vehicular & Pedestrian Circulation Analysis

Finally, the massings divided by the circulation become the space with programs. In order to check the static and dynamic space easily, void & solid technique is applied to analyze the whole space. The solid chunks indicate the overall shape of the massings, while the transparent part designates the boundary of the project.

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.

These spaces are the final pursuit of this project to provide a buffer between residents and visitors to communicate with each other actively and thereby instill vitality on the overall town atmosphere. These spaces can lead these people to do certain activities in the area of both macro and micro scale.

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.

The site is located in a crowded r e s i d e n t i a l a r e a . Pe o p l e c a n n o t protect their privacy from the exterior environment, and do not have personal space to enjoy their life. In addition, convenience facilities are far from the site, reducing the quality of life of residents from the built environment.

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.

This project is to suggest a proper program into this site to regenerate the site and the surroundings. Currently, this area has remained as an abandoned quarry. The 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 point of suffocating CBD environment. Therefore, the project suggests a proper program acting as necessary in the urban contexts, and also in the aspect of architecture and environment, it can provide a fresh space to visitors.

Competition

The site is one of a few locations where it is still remained not dense and crowded. By proposing low and wide massings in the site, the project will make a big breathing hole in the cityscape even if the surroundings are redeveloped and tall buildings will be constructed nearby the site in the future.

The site is divided into 4 parts by two big roads, 8-lane road in north-south bound, and 8-lane road bridge newly constructed as well. Due to this environmental condition, the site is totally isolated from walking access, and entirely dominated by cars passing by with high speed. Furthermore, the previous program, quarry, is also not familiar to people, so that this site has been abandoned for a long time from the modernization period of Seoul since 1960s.

On the north of the site, there is a subway station, Sadang, which is always 24 hour-busy place with employees and students. It has been a hot place for decades, since this place has been a southern center of Seoul, and the entrance gate entering Seoul from the south. Comparing to the surrounding environment, the site is pretty much quiet and desolate even though it is right before the busy place. For the pedestrians and visitors of this place, it needs to become a friendly space to people and totally open to them.

Now, by proposing this project, the site can be redesigned and rejuvenated with citizens visiting here. Functionally, the express bus terminal is located to support the urban life of people, and connected with the subway station to enhance the transportation system from Seoul to the countryside. Diverse cultural infrastructure is located on the other parts of the site, and finally a big ring is connecting the 4 parts of the site in the air for the pedestrians to access easily and enjoy the urbanscape.
