HARAJUKU STATION A Glimpse of Tradition

The current Harajuku Station which was completed in 1924 is the oldest wooden architecture that is adopted as a station in Japan, embodying a British architectural style. In 2016, Harajuku Station went under reform in preparation for the 2020 Tokyo Olympics. This assignment required us to contemplate a new proposal for Harajuku Station while designing an Observatory/Exhibition Space to appreciate the Japanese heritage and culture.

Elevation Facade Design The characteristics of the bipolar city of Harajuku are applied to the facade design.

Viewing the Harajuku Station from the Meiji Jingu forest, it is a single wall with windows that stands straight up in people’ s vision. The station blends in with extruded volume blocks of eastern Harajuku. Viewing the Harajuku Station from the updated city, the facade overlaps expressing a more organic figure, so as to blend in with the scenery created by the trees of Meiji Jingu Forest. This was my

The station flow line concludes mainly within the first floor for train users to minimize the vertical movement for handicapped users. The flow line to the appreciation space may be fulfilled by using the elevator or slopes that extend from the first floor to the basement floor. The station is positioned at a sloping topography, which makes this sloping movement within the station feel natural.

The office floor on the second floor is mainly for employee usage. However, two elevators connect all floors allowing barrier-free vertical transport if necessary.

Highway Over Generations

Academic Project Individual Project

Demolition as a Theatrical Experience

A highway runs above the Nihonbashi River. It was recently announced that the highway would be transferred underground. The assignment questioned us the contemporary form of infrastructure, as well as whether the highway should be preserved or transferred. Half a century has passed since its construction, and the highway faces difficulties such as decrepitude and law revisions. The requisite of the assignment was to create a “theatre� while contemplating about such topic.

Daily Theatrical Experiences Throughout my daily life, I have considered observing construction sites within my commuting paths to be a theatrical experience. It is a temporary stationed phenomenon that changes daily. Sometimes the change is drastic and draws the viewer's attention. I have received some kind of stimulation from it.

Ideal Representation of Nihonbashi in the Future

Nihonbashi

Now that the transfer of the highway has been resolved by the

(Bridge)

Ministry of Land, Infrastructure, and Transport, I decided not to go against the decision, but to accept it as a natural process of civic reformation. My solution was to make the transformation process of Nihonbashi into a theatrical experience. During the process, the architecture site would function as a demolition/reinforcement base of the highway that lies along the Nihonbashi River. It will function as a gateway to the river and support the on-water construction.

Heavy construction equipments will be imported to the site and exported to the river. Once the highway is transferred underground, the architecture site will be diverted into a resource center, preserving traces and memories of the transformation process to succeed for the future.

the highway was first constructed, it made sense to overlap an infrastructure, where such a process had been taken place within the bridge itself over the centuries. Some people still say that the highway should be preserved as an epitome of the rapid economic growth of Japan from 1955 to 1973. However, people’ s sensibility towards certain scenery changes over time. The bridge is the symbol of the city, and the name is carried on to become the name of the city as well as the name of the river. This project proposes a method of succession through a theatrical experience.

H YPER S CHO OL

Hyper School is a term defined by professor Furuya as “ a school that goes beyond schools� . After the great earthquake in 2011, there has been much discussion on what local communities ought to be. Hyper School should be an existence that transforms the community and acts as a stimulus for synergetic effects. Not only does it function

Concept

Management 1

The former headmaster once said, “Ridley College is a Secret Garden.”

It has been over 30 years and situations have changed where there is a need for an exposed garden. However, the idea should to an extent be preserved. This project creates a gradation from a Secret Garden to an Exposed Garden and allows alteration.

A volume is placed to fit the site of the previous Lower School.

2

In other words, the privateness and publicness of the building can be strategically altered, which directly concerns the security of the school as well. The aim of the project is not to create barricades between the school and the public to guarantee security. I believe security can be obtained when the public eye is strategically employed into the site.

The volume is divided into three by a broad categorization of functions.

Two orthogonal passageways divide the building’s interior. The degree of accessibility to each section is different according to the day and time of the week. When a section is prohibited for a certain time, the path to the particular section is closed. The section of activity is easily controlled and security is guaranteed. In this way, the school will be able to control the flowline and the privateness and publicness of the building.

A New Commercial Starting Point

Aoyama Bell Commons, designed by Kisho Kurokawa originally functioned as a fashion center of Aoyama/ Omotesando. At present, established fashion houses permeate throughout the city, and it can be said that Aoyama Bell Commons contributed to spearhead such development. The building however, being detached from the main street, lost popularity along the years and closed in 2014. This assignment required us to create a condensed version of the modern information-oriented society at the site of Aoyama Bell Commons.

Site Background Aoyama/Omotesando is a city that consists of various commercial facilities. Brand-named fashion houses align along streets. These are old-established stores permeating the city, creating difficulties for newcomers to join the industry. Mass production of clothings are displayed in stores, where consumers purchase. This consistent cycle has become fixed, disallowing anonymous newcomers to prosper.

Aoyama Bell Commons The site was previously a commercial facility called Aoyama Bell Commons. The building used to be labeled the center of fashion, however, lost popularity due to the opening of other

fashion houses that had a secured number of consumers.

Below are some of the prototypes that I created to study ways of inserting a social condenser within a volume. To imitate a real condenser, two cores must be created. I used two different methods in order to obtain this.

Information-Oriented Society The recent society sees an overflow of information, creating a society oriented on it. As the information-oriented society progresses, the relationship between individuals dilutes. Exchanging information has become something that does not require a face-to-face interaction. Therefore, it is not rare for people to engage in activities with the anonymous others. The defect is that some of these information have an unknown source, or may be manipulated and contain fallacies. The upside of this information-oriented society is that people learn to create a buffer zone within their minds. In other words, information is starting to be evaluated purely on quality

Modern Social Condenser I interpreted this Social Condenser, as the name suggests, a condensed version of the information-based society where people have to select their own information. I Method 1 Extruding Half 10 Floors & 6 Floors

thought this inclination of the information-oriented society could be applied to a city such as Aoyama/Omotesando where everything is evaluated on name-value. As an experimental method, I created space based on anonymity. By maintaining “anonymity” , the products will be taken out of their context, allowing name-valued

brands and the newcomers to compete on the same evaluation axis. Consequently leaving the consumers to judge purely based on the quality of the products. This is what I called a Modern Social Condenser. My interpretation of a Modern Social Condenser will be inserted in the new Complex to connect the anonymous businesses with the consumers. In other words, this is a system where consumers can contribute to the growth of the anonymous businesses, acting as a catalyst towards their entry to the industry.

Openings that are closer to the floor is kept less angled, and openings that are off the ground may be more angled. Thus allowing the workers in the office/production core to have a finer view towards the Social Condenser.

their context. Each brand is conferred a small space, where they can freely create installations and display their items. If the consumer wishes to purchase, the item will become tagged and sold in the commercial core, where the customer will proceed to purchase. This is when the source of the item will be fully revealed to the consumer. In conclusion, consumers are able to judge purely by the quality of the item, without any miscellaneous information that may jeopardize the essence of fashion. Newcomers are able to compete on the same evaluation axis as others, and the social condenser will support aspiring designers to prosper in the industry.

Ground Floor Design The ground floor design is crucial in a city where tall building blocks are scattered. Commercial areas for Established fashion houses are limited to the lower flats, the higher flats being dedicated to office areas. Commercial building complexes, on the other hand, have most floors opened to the public. In order to incorporate such complex building within the axis where numerous fashion houses align, the ground floor must act seamlessly to the city to enhance mobility. By achieving this continuity, the complex will less likely be diluted in a competitive industry.

CULTUVERT Archival / Thriving Space for Idiosyncratic Cultures on the Culverts of Rivers in Shibuya

The City of Shibuya is composed of multiple culverts. Some are utilized as commercial streets, however, there are many that still remain in the background of the city. This proposal aims to revalue and recontextualize linear voids deriving from culverts, and also suggests a solution for a prevailing obstacle in Shibuya. This project started from the sudden closure of Miyashita Park for civic development, consequently evicting users who composed the idiosyncratic cultures of Shibuya.

In the midst of searching for activity areas, there was news that a new “place” was constructed for us in the site of Rivers in Shibuya.

The street curves and the width changes as I walk through. All the buildings are facing their backs and the street is quiet. A park appears.

I go underground to see the open channel. I never knew such a river went through Shibuya.

I enjoy skateboarding, which I was not able to do for a long time. I also met some friends from the past.

I go back to the surface and see street furniture continuing in a line.

I see a unique building alongside the promenade.

I decide to drop by.

I arrive at the Atelier / Co-Working Space. Some are creating artwork and some are having a small group discussion. A spray work artist talked to me and painted my skateboard for me.

I leave the site and see artworks being displayed and sold on the street.

I arrive at the storage area. There is storage called “Shibuya Time Capsule” where the wall is transparent, allowing people to see what is being stored.

Our culture is visualized.

I also store my skateboard. I am close to Shinjuku Station now. I have decided to call it a day.

Background of Linear Voids in relation to Composing Elements

In addition to the roads dealt in my graduation thesis, other forms of linear voids could be taken into account to possibly generalize linear space as an entity.

This could lead to the discovery of an effective usage of linear voids within a city.

The research conducted for my graduation thesis was applied to the production of my graduation project that followed.

When drawing a train station Voronoi and a 500m radius circle from the stations (sphere of influence), empty spaces appear between these circles. These empty spaces are distant from surrounding stations, that is to say, mobility is mainly created by “walking” . This project aims to revalue the linear void through the action of walking.

Linear Voids in Tokyo Utilization of Linear Voids within Tokyo sees much room for improvement. Recently, there are some cases where linear spaces are effectively used. However, most still remain unused or is assigned a function that is driven out from the center of the city. It is treated as a mere waste box of the city.

Linear Voids emerging as a result of rivers being diverted to culverts tend to be narrow and may also curve at different points. As a result, it may impose difficulty in its utilization and the linear characteristics are not valued. In most cases, it becomes a path that fades out to the background of the city. Cases like Cat Street, where the linear void possesses a significant civic function is rare.

The planned site was chosen accordingly to the Voronoi and the 500m radius from stations. Site 1 and Site 3 are in the empty spaces close to the Voronoi line. Site 2 was placed close to the empty space but not within since the linear void had completely been transferred to a road within the empty space.

Miyashita Park in Shibuya closed for development until 2020. When it closed down, the government forcibly evicted the homeless and many lost their place of activity.

Commercial facilities and a hotel will be newly incorporated and will transform into something different, not solving the prevailing issues. It used to be unique with a skateboard park, rock climbing, and a futsal field. Cultuvert seeks to create a displacement park for Shibuya Culture.

A natural ventilation system is crucial in an atelier-working space for artists, since some materials may be toxic if used in a confined area. The building consists of a semi-outdoor space for such material use.

Future Vision of Cultuvert The importance of this project lies in the three sites being connected with a pedestrian designated linear void. Three planned sites were necessary to highlight the faint connection of the linear void which spans 4km. When moving between the sites, people will utilize the linear void. In other words, people in the same condition (Constituent of Shibuya Culture evicted from their main activity area) will walk through the same passage and a form of unity will be created. Not only are the sites their activity areas, but the linear void itself will also become their activity area and unexpected exchange may occur. This is how the idiosyncratic Shibuya Culture will be cultivated in the midst of civic development.
