Being able to experience, by replaying the loop of desire in line with the ecstasy of sushi melting in your mouth.

This is an architectural compression of research, desires, and memory emerging from the means of commodification of tuna knowledge passed down by generations of the Tsukiji Tuna community in Japan.

Landscape of Differentiated Expertise

Oxford DS6

“The environment we perceive, it is our invention” as postulated

by H.v Forster, the investigation begins with a perceptual journey, to create personal maps of existing places (Sense).

The journey begin with a focus of sight, and then smell and ended with an amalgation of sight and taste. The quantification of the senses creates a vivd sketch of momentary spaces, (Map)ping the human experience.

The device (Wear) functions as an “interpretant” of space. It is an functioning artefact that embodies the aesthetic and ethic criteria and our way of thinking about the [city]space. It contains within itself, names, places, situations, and all the contradictoriness and complexity.

This studio will explore the the future of urban networks whether for people, information or matter; creating projects that rethink, augment and mutate existing conditions.

The symbolism of this real, physical environment which surrounds us and affects our senses can beused to contruct new possible scenarios in the future (Speculate), new ways of interpreting layers of the city.

Flow-place

Studio’s Philosophy

The early part of the 21st Century is seeing a paradigm shift from bureaucratic hierarchies toward technology-driven networks, exemplified by the sharing economy. In this data-centric context the studio’s preoccupation with flow, networks, systems and technology is combined with exploration of the qualitative and the personal, building a narrative which includes thoughts, emotions, memories, and behaviours.

S01

In the speculative future, building are reconstituted into a new entity, via a self organising algorithm, that consist not only of objects, but also events, ideas, activities. A speculative algorithm that is can be used and re-used to design new system of networks, boundaries, borders and constraints. Exploring relationships between physical objects and the flows around them (Transient), a new system of relations, a new kind of infrastructure that imbues a new identity, meaning and performative capabilities focusing on tectonic and programmatic interventions will emerge - towards a new multiplicity.

URBAN SPECULATION Desire and Memory To expand on the theme of performativity of taste, the themes of overconsumption was evident when contemplating the possibilities of a future that captures the experience of taste, visually.

In a society, that overconsumes and data-obsessed, this device brings forth a question: when does it get too much?

Taste City Identity of a city is made up very much by the palettes of its resources, its locality creating a strong economy force of supply and demand.

Such is the case of Sushi, the globalisation of sushi and its evolution into a modern delicacy reveals a complex dynamics of globalization and “a virtous global commerce and food culture”( Issenberg, 2007).

Fish on a macro scale The research in taste, and its active feedback depends on previous memory and experiences. Data in the form of electrical impulses were measured by a working of EEG device and also a visual platform that exposes a new dimension of expression in terms of taste.

“Seeing is believing” is applied to the dimension of taste and memory.

Details of global freighting of fish to Japan, in particular, Blue Fin Tuna, was researched into charting Japan’s sushi economy, with a special emphasis on Tokyo’s Tsukiji Market.

“Taste” Origin Latin Tangere (‘To touch) Gustare (‘To taste’)

Old French Tast Taster

(Touch, Try, Taste)

Taste (‘touch’)

Our eyes let us “taste” food at a distance by activating the sense memories of taste and smell. Even a feast for the eyes only will engage the other senses imaginatively, for to see is not only to taste, but also to eat. The chef’s maxim, “A dish well presented is already half eaten,” recognizes that eating begins (and may even end) before food enters the body. Television cooking shows—there are now entire channels devoted entirely to food—are a way of eating with the eyes by watching others prepare, present, and consume food, without either cooking or eating oneself. Cookbooks, now more than ever, are a way of eating by reading recipes and looking at photographs. Those books may never see the kitchen. Indeed, experienced readers can sight-read a recipe the way a musician sight-reads a score. They can “play” the recipe in their mind’s eye.

While not unique to the experience of food, visual aspects of food are no less essential to it. First, the eyes play a critical role in stimulating appetite. Visual appeal literally makes the mouth water, gets the juices going, starts the stomach rumbling—in other words, sets the autonomic reflexes associated with digestion in motion. These responses—salivation, secretion of gastric juices, hunger pangs—are involuntary, spontaneous, instinctive, though the cues are ones that we learn. Second, the eyes are bigger than the stomach. Visual interest can be sustained long after the desire to taste and smell has abated and appetite has been sated. Perhaps for this reason, the most spectacular displays are likely to come at the end of the meal.

Taste in its most materialistic form in relation to architecture can define areas within a macro context in terms of districts, where the aroma and mere flavour of a certain cuisine can help initiate place-making and memorable journeys. Mnemonics and genus loci quality of the sense of taste is one that exists unconsciously in the collective thought process of the masses, and not confined to the few individuals actually paying attention to it.

The sensation of flavour is different to each person, as is the perception of a space to its varied user, to each their own appetite. Common terms of taste experience include relishing, tang, savouring. An individual appreciation of the burst of ingredients merging together to form a singular emotional experience of pleasure, indifference or dislike. The qualitative of taste, is expressed by the device, coded by quantitative data. It is in its representation of sensation that runs in line with experiencing architecture. Architects, in a nutshell, are always trying to define the intangible aspects of either society, culture, community into building design by trying to abstract them into form and space. Justification of use of tools at hand, using tangible sources like ingredients and architectural elements to provide an intangible experience. With the device, we can finally complete the full circle, by recreating it into a tangible result, completing the experience, both sensorial and spatial.

Taste can also help the architecture discipline and its practice extend to domains varying “from the physiological to the atmospheric, from the sensorial to the meteorological, from the gastronomic to the climatic. In a world where more and more skeptics and cynics are born everyday, a want for a interactive building that transforms and projects the internal physiological experience, the need for justification and visual confirmation is an actual qualification for future architecture. An architecture or system that engages the senses of the users, whilst retaining its covert functions and ambience.

Value is marked up, determined by selected auction houses and companies in Tsukiji. Manipulation of stocks.

Future anticipates that intermediate wholesalers with the skills and personal relationships with the end users, and trade owners will find new distribution system.

A city needs an ever evolving creative myth, allowing its inhabitants to understand it collectively and imagine its future. A new creative myth generates a new genius loci. Sometimes a myth fades and a new myth must replace it for a city to prosper.

With the displacement of independent intermediate wholesalers, there is an opportunity in anticipating new outlet for their skills in the future.

PROCESS CENTERING, THE THEATRE OF CONSUMPTION PRECEDENTS Process Lengthening, “The quest for slowness, which begins as a simple rebellion against the impoverishment of taste in our lives, makes it possible to rediscover taste.”

The Slow Food Pavilion will be situated in an area of 3,500 square meters at the eastern end of the Expo’s central boulevard, alongside the Mediterranean Hill. The scheme sees three built structures grouped around a central plaza, reminiscent of the rural Lombard farmsteads, subdivided into a theater, exhibition space and tasting area.

‘Orto in Condotta’

by Herzog De Meuron

An Educational Inniative

A pavilion that promotes the core principles of this year’s Expo - biodiversity, sustainable agriculture, and access to food that is good, clean and fair for all.

“Our architectural and curatorial proposal is based on a simple layout on tables which creates an atmosphere of refectory and market,” continues Herzog & de Meuron. “People can watch visual statements and read key texts about different consumption habits and their consequences for our planet, they can meet and discuss with exponents of sustainable agriculture and local food production to learn about alternative approaches, and they can smell and taste the richness of agricultural and food biodiversity.”

The design of the structure is intended to mirror the the contents it is hosting: simple, lightweight, low environmental impact and long lasting. A conscientious effort to promote agricultural production above architectural prowess.

After the Expo ends in October, the structures will be dismounted and reassembled as garden sheds in school gardens all over Italy as part of Slow Food’s educational initiative ‘Orto in Condotta’.

The tripartite pavilion is subdivided into a theatre, exhibition space, and tasting zone, with each program occupying compact areas of less than 455-square-meters apiece. Herzog & de Meuron’s understated approach mirrors the grassroots nature of Slow Food, and is a conscientious effort to foreground agriculture and food production as against architectural showmanship.

Maintaining a human scale, the single-story pavilion controls traffic volumes and flow and allows visitors to more effectively engage with on-site experts and written and visual material. The three timber structures circumscribe a triangular courtyard, and are formally suggestive of the traditional Lombardian farm house, or Cascina.

“Back Office”

Upstream from the marketplace, brokers assemble catches from separate producers into larger and larger flows of commodities of increasingly homogenous character for auction at Tsukiji and similar wholesale food market.

Downstream from the marketplace, however, customers do not demand large quantities of single commodities; they want small amounts of wide range varied products.

Crucial task of auctions and the traders is to match supply with demand, by transforming one bulky product stream into another that is much more diverse.

close interprersonal ties in a highly interdependent social world.

They take a quiet pride in flexibility and autonomy that come from running their own business.

However, intermediate wholesalers are often confronted with the same problems of corporate continuity, risk and credit, labor and capital, and supply and demand that any business must face.

Sales of volumes of their businesses may be many times larger than that of the tiny mom and pop stores that charcterize the small scale sector of the Japanese domestic economy (Patrick and Rohlen 1987; T.Bestor 1990).. In fact, in many cases, they are incorporated as joint-stock co-operations.

The marketplace is not a welcoming place for labor organizers.

Many of the employeers who potentially might be union members regard themselves as floating, part0time workers, and hence have little interest in colelctiev efforts to improve their working conditions.

Small scale sectors of the Japanese economy and particularly the employees of family-run enterprises have markedly low rates of union participation.

Learning with the Body (Karada de oboeru) When handling seafood, proper attitude and care that traders gloss as kata, proper form, refes to the precise motions of a skilled artisan. The phrase “to learn with the body” describes mastery of these physical principles of work.

Fictive Kinship

The fading artisanal spirit reflects the decline of apprenticeship and the changing relationships among labor and management, this decline affecting the social fabric of the marketplace as a whole. It is a dense network of fictive kinship created through master-apprentice relations.

Trading

Artisanal Apprenticeship

An apprentice spends two hours each afternoon sharpening a single tuna knife longer than a man’s arm.

“Maguro no Kaiwa”; the conversation of the tuna, that is to listen to the fish as they are cutting it; to gauge the pressure of the forearm and wrist on the hilt of the knife and on the back of the blade from the smooth sound of a blade sliding through a block of red meat; to be alert for the small, sharp crunch when the blade reaches the bottom, outer layer of the skin ; to respond to that crunch - almost before they hear it - with a short concentrated push to put the blade cleanly through to the cutting board.

Trader guilds rearrange the physical layout of the marketplace to erase locational disadvantages.

On the institutional end of the continuum, intermediate wholesalers draw together through several kinds of formal groups structurally

STROKES

involved in administering a marketplace. These include customary trading communities, fleeting political coalitions, and enduring trae guilds organized around specific commodities, as well as overaching federations-to which Tsukiji Intermediate wholesalers all belong.

Trading communities form around specific auctions, the specialization of each group directly reflecting the demands created by Japanese food culture. The premium on fresh seafood and the vast array of speicies, grades are critical in defining the trade.

Not only are the culinary skills, processing techniques, tools and market knowledge necessary distinct,its demand structures differs from species to species.

Abstraction of Tuna Cutting Ritual

The Tuna Praxis Praxis is a key in meditation and spirituality, emphasis is placed on gaining first hand experience of concepts.

Wisdom is always taste—in both Latin and Hebrew, the word for wisdom comes from the word for taste—so it’s something to taste, not something to theorize about. “Taste and see that God is good,” Tasting the Architecture, Trusting the experience, before institution or dogma.

The Savill Gridshell

Composite At each floor level, two perpendicular pairs of glulam larch timber beams intersect each column. The beams nest into 3-inch-wide-by-10-inch-deep notches in the columns. “We knew we needed to make a deep enough notch in those columns to fit the beams [and] generate that moment connection,”.

The larch and oak logs were carefully selected and graded prior to sawmilling. This entailed an integrated procurement process involving the forester, processors and carpenters. The locally-grown larch, planted in 1935, is generally of high quality. The good management of the timber stands made it possible to examine the standing trees and select slow-grown, high trimmed timber which was likely to have close grain and minimal knots.

On Nest We Grow’s first and second floor levels, cross-bracing members bolt into tabs of the sandwiched steel plates. This crossbracing combined with the moment connections and catwalks at the third- and fourth-floor levels provide the necessary lateral resistance against seismic and wind forces.

The fabricators had prior experience of finger jointing oak but not larch. Similar adhesive techniques were used to those for the oak in the Weald and Downland project, but because this was still regarded as not fully proven, a test programme was specified. This demonstrated a strength class of up to C30 for the finger jointed larch laths. Because of the nature of the gridshell technique, the 6m off-site lengths had to be scarf jointed on site to produce continuous lengths of up to 36 m.

The Akkerwinde bridge is made so unique by the fact that the wooden construction is able to support the steel deck. Furthermore, traffic from the highest traffic class (60 tonnes) can drive over it. A list of wooden bridge facts: Length: 32 metres Width: 12 metres Height: 16 metres (not including the substructure) Total weight of the wooden superstructure and steel substructure: 360.000 kilo Weight of drive bolts and link-up bars: 9000 kilo Quantity of wood: 690 cubic metres Type of wood: Accoya®
