Proposal for reuse of Iwafune-oki oil and gas field platform

Outline of work

So far, 12 maritime platforms have been built in Japan. However, only the Iwafune-oki oil and gas field off the coast of Tainai City, Niigata Prefecture, is still in operation, and the remaining 11 units have already been dismantled and removed. The mainstream method for dismantling and removing the marine platform is to cut the structure near the seabed and lay it on its side in the sea to leave it. In addition, the marine platform has been quickly dismantled and removed because it cannot be left on the sea due to navigational safety after the operation is stopped. On the other hand, Japan's maritime platform construction technology is excellent enough to be exported overseas, and it is robust enough to withstand waves and earthquakes.

In this design, we explored the possibility of reusing the maritime platform, which plays a part in Japan's energy production, as an aquarium and accommodation facility after the oil production is stopped. The huge scale building surrounded by the sea is full of attractive space. Using existing elements as clues, we created a variety of spaces.

As you experience the architecture, you will witness the huge structure of the marine platform. Knowing that we have spent a great deal of resources and energy on facilities to produce energy, we realize the tremendous hugeness of the industry that supports our lives.

Moving wind smoke
――Research on moving space that creates natural ventilation ――

Outline of work

Natural ventilation, as explained by Bernoulli's theorem, has the disadvantage that it does not work in the absence of wind. Therefore, in this research, we devise a mechanism that enables natural ventilation by utilizing the relative air flow generated by moving the space itself. Next, the spatial shape and opening arrangement for this mechanism to work effectively will be clarified by CFD simulation. Finally, we will create a small real space based on the above examination, verify the effectiveness of the mechanism, and present the possibility of a new smoking space in modern cities.

In this design, in order to create a relative air flow, the space unit is mounted on a four-wheeled vehicle and towed manually. In addition, an air supply port was installed in the lower rear part of the space unit, and an exhaust port (with a smoke exhaust filter) was installed in the upper part.

As for how to use the real space, it is assumed that you will visit sightseeing spots. The opening is designed so that the scenery of the city is easy to see and people's eyes are not bothered. When stopped, the two walls are flipped up and connected to the external space to be used as a place like a teahouse where many people gather. This is reminiscent of the lifestyle culture that used to stop at a teahouse and take a break when traveling between post towns on a kago.

By designing these real spaces, we propose the possibility of new smoking spaces in modern cities.

Research on small-scale development of a former railroad freight site in the Tokyo area  --Proposal of a freight-only linear site -

Outline of work

Railroads support Tokyo, which has a hinterland population of 37 million. Railways that transport passengers and freight have changed their transportation system to meet the needs of the times, especially for freight. The site of the freight line that remains in the Tokyo area is a symbol of railroad freight that appeared and disappeared due to the modernization of Tokyo. The freight carried by the railroad was linked to the industry that took advantage of the location of the town, but the current redevelopment of the freight line cannot take full advantage of its characteristics and is buried in the town. The development of the former railway site should be unique to freight lines. Therefore, we will reconsider the basis of town development unique to freight lines. While 50% of the site is being developed on the road, the site of "Kawasaki-Hama-Kawasaki" that has not been developed on the road is targeted. The impact on the area around the freight line is roughly divided into two types. There are cases where the freight line is arranged so that it goes straight along its axis (road development type) and cases where it is completely ignored and the surrounding buildings and blocks are non-direct (site development type). The form of architecture is created based on the unique landscape created by the influence. There is a big difference in the development use of the site depending on these two types. The road development type is likely to become a road, and the site development type is likely to be developed for residential store construction. Therefore, as a program that makes the best use of the relationship with the surrounding area of the site, commercial and apartment buildings will be placed on the ground in addition to the existing welfare complex. By passing a bicycle path to the upper part as a complement to the function of the road lacking in this site, we propose a bicycle path construction that will serve as a base for regional revitalization while eliminating the division of the surrounding area.

A large mansion with 30 entrances
Ginza Aerial Art City Concept by Regenerating Infrastructure — Designing a Cross-Urban Architecture by Making the Tokyo Expressway Pedestrian and Combining Museums and Apartment Houses —

Outline of work

Since the high economic growth, railroads and highways have been rapidly expanded, and it can be said that public spaces in Japanese cities have been transformed by these "infrastructures". This plan re-evaluates civilian buildings (elevated highways) that may become useless as the times change, as part of the history of Tokyo that embodies high economic growth, and walks. By reorganizing it as a pedestrian space, it presents a perspective on a new urban public space in the future. As a conversion plan for the Tokyo Expressway, which was built as a bypass for traffic mitigation, the expressway, which can be said to be a transit device made only for passing cars, will be reorganized into a "pedestrian space" for people. The total length of about 2km on the Tokyo Expressway running in Ginza has been converted into a pedestrian space, which has been disassembled into three areas. Draw a master plan in each section and develop in the core part. Instead of the conventional skeleton x infill conversion, the skeleton as an architecture is inserted into the skeleton as a civil engineering structure, and in a diagram that can be taken as a skeleton x skeleton, an atrium space is formed at the overlapping part and a connection relationship is planned. .. The plane of the feet is planned magnetically around the atrium, and the living space is planned on the atrium. We will set up an art museum and an apartment complex, propose a connection relationship with adjacent facilities, and present a new image of the city in Chuo Ward.

Public facilities that change from shelters to temporary housing after a disaster  ――Proposal of design mainly for functions in extraordinary times ――

Outline of work

We designed and proposed public facilities that incorporate the functions of evacuation shelters and temporary housing. In the event of a disaster, shelters will be opened to accommodate evacuees. However, as the evacuation life becomes longer, there are many cases where evacuation shelters and waiting areas are changed. The background of this problem is the movement of evacuation shelters due to the narrowing of space, the elimination and consolidation of facilities due to the recovery of daily operations, and the difficulty of securing the site for temporary housing. However, such changes in the environment after a disaster sometimes destroy the connections and communities created between the victims, causing withdrawal and lonely death.
In order to solve these problems, I wondered if it would be possible to propose a facility that can handle long-term evacuation life by incorporating the function of an evacuation center in advance in a cultural facility where the suspension of daily operations is relatively not a problem. Therefore, based on the existing libraries and parks, we designed public facilities with built-in functions of shelters and temporary housing. When a disaster occurs, this facility will quickly turn into an evacuation center, then switch to temporary housing, and after reconstruction, it will return to normal usage. In addition, in order to respond to changes in the environment after the disaster, the problems of evacuation shelters that occurred in the past earthquakes were extracted from the past literature and organized and analyzed in chronological order. After that, in order to respond to these problems and changes in the environment, the proposed facility will be a variable facility that changes in four stages after a disaster, and the facility management policy at each stage and problems that should be resolved with priority will be examined. bottom.

Ah and Apa and Mento

Outline of work

Kamoi, located in Tsuzuki-ku, Yokohama, is an interesting area with a mixture of residences, warehouses and factories. We thought that the expected population decline would increase the building stock of warehouses and factories, and by using them, it would turn into an attractive city.

The large space of a warehouse is ideal as an activity base for artists, and incorporates the element of living there. It is like sleeping in a school classroom or corridor while preparing for a school festival.

By making it open to a large number of people, including local residents, you can feel the background of the work, such as the lifestyle and philosophy of the artists who live there. In this way, by performing the entire cycle of thinking, production, and exhibition in one space, you can experience something that cannot be experienced at a museum.

The front yard is a free space that can be used freely, and people who work nearby can eat lunch during lunch break, elementary school students can play after school, and there is a cafe inside so you can have tea. The exterior space between the two buildings will be an imaginary space, a place for artists to relax and get inspiration. In addition, this is a new type of apartment that allows you to enter "inside" as needed, such as only the front yard, only the cafe, and even the space of the artist inside.

Ruins to inherit
――The site of the stone mine concentrator to a whiskey distillery and accommodations ――

Outline of work

Yasuishi City, Iwate Prefecture, is the birthplace of the modern steel industry. The site of the stone mine concentrator is located at this location. A concentrator is a place where ore and non-ore are concentrated since the time when ore was blasted. The majestic figure on the slope has been dismantled now, but the foundation and retaining wall still remain. The theme of the master's design is to maintain and renew this place, which can be said to be the historical identity of the stone.

For that purpose, it is important how to position this place in the whole city of Sekiishi. I investigated the various possibilities that exist in Sekiishi City and concluded that the function as a "production site" and "new base" is suitable for this place. We propose a whiskey distillery as a "production site". There is natural water that can be collected from mines in Sekiishi City. The port of Sekiishi secures the distribution side, and the abundant wood resources are ideal for barrels and fermenters.

The raw material barley is produced in neighboring Morioka, where Morioka cold noodles are famous. And although the distiller, which is important for whiskey, needs to be made of copper, copper is also mined at the stone mine, and copper ore still exists. By making full use of the resources that exist in Sekiishi City, it is possible to make complete Sekiseki whiskey. In addition, there are many industrial remains in the stone. One of them, Hashino blast furnace, was registered as a World Heritage Site. Many of these remains have problems with access from urban areas. Therefore, we proposed accommodation facilities using the site of the former concentrator and aimed to create a new base.

Silk Line Factory-  Yuki Tsumugi Industry Promotion District Plan by Utilizing Low-Use Freight Tracks  ---

Outline of work

In recent years, the number of railway lines that have been discontinued or underutilized is increasing due to the effects of industrial restructuring and regional decline. Most of the track site is undeveloped, and the site where it is being maintained is undergoing promenade / green road maintenance and road maintenance, but it is limited to the maintenance of the old track space. The Takaoka Electric Mfg. Co., Ltd. line in the eastern district of Oyama City, Tochigi Prefecture, which is becoming one of these railway lines, is a freight track laid to transport large transformers and is used only a few times a year. Community route development in land development is being considered.

In addition, Yuki Tsumugi Sangyo, which is a traditional industry of Oyama City, has been one of the city's industries since the Meiji era, but it is declining due to the influence of technological innovation, and many traditional techniques by hand have a long history. It is about to cease in our generation.

Therefore, in this plan, by using the open space adjacent to the low-use freight track and connecting the production process of the reconstructed Yuki Tsumugi industry, a livelihood of the city that is integrated with daily life will be created for the purpose of inheriting the tradition. Propose an industrial district plan and develop a living landscape in the eastern district of Oyama City, Tochigi Prefecture.

■ Silk Line Factory Consists of 5 bases related to Yuki Tsumugi Industry.
① Workplace responsible for cocoon ball production by sericulture breeding ② Workplace for producing raw silk from spinning live silk cocoon balls ③ Workplace for dyeing and patterning live silk to be tied ④ Workplace for weaving cloth ⑤ Market Plaza A plaza that sells products produced at each base and serves as a place for PR.

The mining city dreams of a festival

There are two "voices" in my hometown.

One is "screaming". It is no exaggeration to say that my hometown is declining. The other is "dynamite sound". There is a big existence called a lime factory in this town. However, due to changes in the times, factories have declined, and the city has shrunk accordingly. Now that we cannot see tomorrow for the mining industry, we should think about how it should be. Therefore, we will study the city with the mining industry, that is, the "mining city", and propose the reconstruction of the mining city for the purpose of revitalization.

The stage is "Kuzuu, Sano City, Tochigi Prefecture". The "lime factory" that exists as a synonym for this town and the "discontinued line" that was created because of the lime factory will be targeted for planning, and an educational program called "accommodation learning" will be put together in these two places. By opening the lime factory, which is full of historical and spatial experiences, to the city as a "school for learning about society" and the abandoned railway line, which was once the backbone of the city, as an "accommodation for learning about life", children can learn and at the same time. I thought that the energetic appearance would give the city a lot of energy.

To conclude, this time I researched based on Kuzuu, but if other mining cities are developed in the same way, a different landscape of mining cities will be created. To that extent, it was full of a wide variety of potentials.

I am convinced that the day will come when the mining city will be proud of itself with a loud voice.

Apply space-time (time)-  Shibuya Station Toyoko Line elevated line site plan  --- 

On March 16, 2013, the Toyoko Line became a direct connection to the Fukutoshin Line, and Shibuya Station became a transit station. Therefore, there is concern that people may flow out of Shibuya. Therefore, I thought that it was necessary to create new value so as not to lose the bustle of Shibuya. In this plan, we propose a method to create a sustainable city by using the site of the elevated line of the Toyoko Line. We analyzed the origin of Shibuya, which has developed by gradually overlapping time and space, and adopted it as a design method. By 2026, when the Shibuya station block was completed, we designed the road from Shibuya to Daikanyama in six stages, taking into account the changes that occur around Shibuya. In addition, in this design, we left the elevated line that created the culture of Shibuya as the same thing in the city, and designed it to encourage the renewal of the city around the elevated line as a way to create new value. It is a design of a city that keeps updating while leaving memories. Specifically, we will rebuild the aging elevated line. When a part of the building is being rebuilt, there will be a detour. Since this detour is slightly deviated from the original position of the elevated line, the relationship between the surrounding site and the elevated line changes a little. Embed a space that triggers value there. Space changes its quality while reading the times step by step, and pays attention to the changes in the city. By embedding a space that encourages change little by little in the city, a city where planned cities and unconsciously born cities coexist is created. Time and space accumulate, and new value continues to be born.

Meidaimae Station Area Development Plan-  Design of urban space that coexists with elevated railways  --- 

Tokyo is where continuous grade crossing projects are progressing in various places. The areas divided by railways have developed with their own characteristics, but the three-dimensional railways that eliminate the divisions may completely change the urban structure. In this plan, at Meidaimae Station, which is planned to be elevated, we propose an urban space where the elevated railway and the architecture coexist by treating the elevated railway and the surrounding blocks as an integrated site.
The area around Meidaimae Station, where the railroads cross each other, is divided into zones such as "station proximity," "shopping street," and "residential district," and the way of elevated buildings and architecture corresponding to each context is presented. For civil engineering structures that will newly appear in human-scale towns, we will balance the new environment that changes due to the elevated structure and the inheritance of the urban structure that was created before the elevated structure. We plan to connect the station square, the shopping district, and the residential area to the uniform railway viaduct that linearly crosses the city, and try to bring out the new charm of the railway viaduct by softening the boundary between the viaduct and the city. rice field.

HARMONIZING RESTORATION-Renewal of Karasuyama Girls' High School Building to Elderly Complex-

Architecture is created as an asset of society and ends its role so as to be at the mercy of changes in society. The repetition has supported a society that is all about growth. However, now that growth has peaked, architecture, which has become a shell for its use, stands empty as if it reflects society. Karasuyama Girls' High School.
Due to the reorganization of the high school in 2008, it will be integrated with Karasuyama High School, and it has been decided that the school will be closed after the graduation of the students enrolled. Right now, it is an architecture that is about to become a shell for its intended use.
In this plan, we will look at the uses that will be lost due to changes in society and the uses that will be needed due to those changes, and at the same time, inherit the richness that the architecture has built up over a long period of time, and the past and future. Aiming for architecture that connects the two. Think of architecture as if you were following the rhythm and rhyme of an original poem and rewriting it into a new poem with a different meaning, or by superimposing a new melody on the original music to play a beautiful chord. The architecture is designed so that the function of architecture blends into the urban structure of the area, and the form of architecture embodies the relationship between the school building, the surrounding environment, and the earth.
The harmony of the architecture on the small hills overlooking the city echoes in the area and shares memories across generations of the people who live there. I envision such a future and propose it as a method of renewing architecture under the proposition of "harmony."

Artist in Residence with Dock-Proposal of Public Building to Create and Urbanize Local City Onomichi-

One of the problems in Japan today is the regional disparity due to the city-centered policy that disregards local areas, due to the change in policy policy due to structural reforms in recent years. Today, the impact on rural areas is increasing, and some municipalities are proclaiming bankruptcy. Furthermore, we have entered an era of turbulence such as politics, environment, business, and life, and a paradigm shift has occurred in people's values and all fields. ing. The planned site, Onomichi City, Hiroshima Prefecture, is also one of the local cities that have problems due to its harmful effects. Anxiety is a problem. In addition, although the shipbuilding industry is thriving, some shipyards are closed due to all economic fluctuations and changes in shipbuilding demand due to the enormous size of ships such as LNG carriers in recent years. Onomichi City is in a transitional period in which it must be aware of this situation and respond to it.
Therefore, when planning an artist-in-residence in the local city of Onomichi, this plan will solve various problems that Onomichi City has by making effective use of the former shipyard site that was closed and giving vacant houses a new residence function. It proposes the possibility of Onomichi City for the future, which can improve and improve the regional promotion and the regional environment, make the creative city a reality, and add another feature to the city.

Resonant Space
-Zeche Zollverein Museum-

There are structures that have purely aesthetic effects, which are neither works of art nor buildings. Ancient ruins and ruins are close to it. What they all have in common is that, apart from the objective aspects of painting, sculpture, and architecture, the three-dimensional space they compose and create is the subject of artistic expression. There is a kind of mental space that goes beyond perceptual recognition.
Now that the concept of art itself is changing, there can no longer be a museum as a general solution for all kinds of art. The museum itself needs to be a work, not just an exhibition space that shows art. By thinking and treating art and architecture at the same time, we design an architectural space that resonates with each other, maximizing the spatiality peculiar to the work of art.
In the ruins of the Zolferin coal mine left behind on a vast land of 100ha in Essen, western Germany, the universality and eternity are assimilated and confronted with the meaning of the works of art. We create a space that resonates by combining all the elements such as the exhibition method, the production of exhibition equipment and substitutes, the exhibits that are the contents, the buildings that are the containers, and the cities that contain them.
Resonant Space is to cultivate the unique world of the thing and place, and to create new meanings, interpretations, and stories there.

Trench Town Umeda Factory site regeneration plan using soil purification treatment

In recent years, large-scale pre-created open spaces found in the northern part of Tokyo Ward have become prominent. They are often the site of closed factories or abandoned vehicle maintenance sites due to relocation to rural areas or overseas. Moreover, even when these are redeveloped, the spatiality and architectural programs that once existed on the site are rarely omitted, and they often become urban spaces that are spatially and purposefully independent of the surrounding area. Therefore, we focus on the soil purification treatment that accompanies the reuse of the former factory site, and propose the regeneration of the urban space using the excavation work that occurs in the process as a design project. Soil purification treatment refers to the past land history, and if harmful substances exceeding the specified value are found, the soil is replaced by excavating the site. In addition to the last land use, the site survey also includes past usage history, so the depth and extent of excavation includes the time of the land over a long span. However, the elucidation of the land use history by such surveys and the consequent unevenness of the land caused by the soil purification treatment, that is, the historical and physical context, are rarely reflected in the redevelopment of the site. Therefore, by positioning the unevenness of the ground carved by soil purification as a context peculiar to the site and using it, we are presenting a method of spatial composition by linking civil engineering work and construction work. We believe that this will make it possible to revitalize the environment by taking advantage of the unique characteristics of the place, which has often been overlooked, such as the origin of the site.

By considering the vacant house as a classroom, the apartment house as a playground for children, and the entire city as a school, a new relationship between the apartment house and the vacant house is constructed.

Sumi-Sumi-TRAIN ~ Carrying a lively ~

I thought about living in a train full of memories. The site is known as back alley culture, and Shimokitazawa is a gathering place for young people who like theater and music. Convert a scrapped train. The inside of the 10-car train will be a linear common area, and dwelling units, commercial facilities, galleries, and semi-outdoor theaters will be placed around the linear common area. A total of 30 dwelling units, 6 commercial facilities, 2 galleries and 2 semi-outdoor plazas will board the train and be connected via a linear common area. When you stand in a common area, your eyes are lost and people's activities overlap. People live in the usual scenery seen from the train window. The divided culture of Shimokitazawa and the trains carrying the people who live there continue to carry the bustle.

chimney Cond

With the development of technology, the time will come when the waste disposal facility will be unnecessary. At that time, we will convert the chimney that is no longer needed, bring it back to life, and propose a house that uses the shape of the chimney. For those who look up at the chimney, it shines as an environmentally conscious landmark, and the chimney moves around like breathing. It uses the power of the wind to generate electricity and power the city. In addition, it has walls that generate wind power to create a comfortable surrounding environment, and by using the power of clean wind to prepare the environment inside and outside the building, it also helps reduce CO2. A proposal for a chimney-type apartment building that has a comfortable environment for cities and people and an energy supply system for the city so that living things can breathe.
