Tokyo

Tokyo geographically is made up of plateaus, hills and mountains. Along its eastern border runs the Edo River, the Arakawa River and Sumida River downtown divides Tokyo from Chiba Prefecture, to the south of Tokyo the Sakai River and th lower stream of the Tama River separates Tokyo from Kanagawa Prefecture with many of its tributaries running through Tokyo. Many of the rivers and tributaries are no longer visible to those living and visiting Tokyo, extensive infilling of canals, moats and rivers occurred after the WW1 in

the Meiji (restoration) period when Japan rose to become a major industrial nation. The sequences of events led to rapid growth and centralised population densities, transportation shifted from the water onto the land. Roads were widened and more footpaths were established which eventually led to tributaries being buried under the city.

and Shimbashi, Sukibashi were all old districts of old downtown area of the Edo period which were all connected by bridges - where views of hills and water in a dense built up city brought a sense of spaciousness where people would gather - where activities such as markets and festivals also took place.

Wet has been replaced with dry. Place names such as, hashi, bashi meaning bridge or jima, shima meaning island and kawa, gawa are seen but are no longer visible. Places like Kyobashi

Ginza

Ginza is a district in the Chou Ward of Tokyo, Japan â&#x20AC;&#x201C; its 87 ha and is well known as a popular shopping district. Ginza was developed during the Meiji Era (1868-1912) to become westernized. Hence it has a distinctly strict grid set against many other districts of Tokyo with irregular and interlocking street networks. The implementation of this current urban model was implemented in 1872 by a British engineer Thomas Waters, where the intension

was to develop a traffic efficient city with large thoroughfares and boulevards. However despite planning large urban blocks these blocks can be broken down to many sub blocks subdivided by secondary streets and tertiary street networks. The scale relationship dynamic between small alleyways and tall and smaller buildings in large blocks is a fundamental character of the Ginza grid.

The endless movements within the Ginza grid offers a dynamic experience to pedestrians as primary, secondary and tertiary streets are interconnected with little to no cul-de-sacs. Tertiary streets extend the footpath in-between buildings and create alternative routes through large urban blocks. The existence of these many little streets collapses the hierarchy of the large orderly and strict grid of Ginza which becomes one of the defining spatial characters of the Ginza street network.

Nihonbashi (Edobashi) is a district of Chou Ward and it is located east of the Imperial Palace and north east of Ginza. In the Edo Era Nihonbashi was a major mercantile, and continues to be one of the largest commercial centres in Tokyo and is home to the famous Nihonbashi (Japanese bridge), which is connected to the Tokaido

highway with Nikko Kaido, linking the old capital (Kyoto) with the new capital of the Edo Era (Tokyo). When its grid was introduced it was orientated following the lay of the land in the Low City (Shitamachi), which were aligned with the canals systems.

Second World War, 1945 areas like Ginza and Nihonbashi were re-developed and wider boulevards and main streets (omotedori) were established.

Information Exchange

Nikos A. Salingaros – Urban Space and its Information Field Explores the use of urban space linked to the information field generated by the surrounding environment. Where a successful urban space offers tactile information – sensory deprivation or overload is uncomfortable because it means we have no information about the threats or

opportunities that is around us. Information and Exchange is translated into colour – where each colour is given a value, high values (score) are awarded based on the intensity of the hue, low hue intensity is awarded a low score and white and black is null. The scores are then weighted, the low scores are boring and unpleasant – which

usually references, blank walls or unbuilt spaces and sky. The higher scores are exciting because it allows the opportunity to explore.

Prospect & Refuge

The information exchanged with pedestrians provided clues Signages, doors, windows coded in colour provided information to pedestrians and allowed them to read their environment, it creates excitement and the opportunity to explore, or the security to navigate the street. Information Overload The theory of prospect and refuge - seeks secured environments and thereby meeting human psychological needs. Such environments provide people with the capacity

to observe (prospect) without being seen (refuge) â&#x20AC;&#x201C; in the expanded theory by Grant Hildebrand, prospect and refuge is the concept of complexity, exploration and opportunity the opportunity to observe or hide. The qualities of these space-particularly including volume, configuration, access to natural light and outlook can significantly influence a personâ&#x20AC;&#x2122;s emotional response to that space. Enclosed spaces will evoke a feeling of safety

or relation while a view from the space can add levels of stimulation and excitement. Aesthetics is based on experience, behaviours and strategic relationships, humans evaluate environments functionally, searching for the strategic opportunities they may provide, and movement through the space allows a degree of choice.

Cellular Automata

There are 3 different types of components for the aggregation, public/commercial/residential components. The components are connected through attaching bars. The openness of the components determines the hierarchy of attaching bars. The public unit has 4, named from P1-P4, the commercial has 3 and residential has 2.

To set up the rule for aggregation, the principle is 3 residential components and 1 commercial component share 1 public component, comprising a basic urban unit.

residential components will be connected to either public or commercial components. The units are then connected to form the city.

There are 2 steps to generate the iterations. The principal rule is to determine the connection between public and commercial components, whether it is at P1/P2/P3/P4. After that, the

Circulation and Observations

plus:

minus:

• A multitude of varying experiences and qualities

• The circulation paths only facilitate pedestrian activity on-foot, and do not cater for those with inhibited mobility.

• Circulation paths around the outer perimeter as well as through inner areas. • Quite an intimate tone throughout • Many opportunities to interact with other residents or workers in open spaces and pathways

• While the paths provide a multitude of different experiences, they are not efficient or intuitive; it would be difficult to navigate for non-regular visitors and time-consuming for those solely aiming to get from one destination to another.

• There is a lack of choice in the pathways; users are often forced to use specific individual nodes to ascend or descend this example. • Pathways often cross next to or over residential blocks, which may be undesirable for privacy or security reasons.

1. Wide Circulation Path

3. Water Facade

5. Communal Area

1a: Water running along the center of a large circulation path: • The movement of the water mirrors and complements the movement of the pedestrians, giving a sense of accompaniment, and perhaps spiritual support for their continued movement. • Breaks up the wide space of the circulation path, creating a less exposed experience. • When experienced in static conditions, opportunities for play/touch/observation of the water are greater. Value: 3

3a: Water falling down facade: • Shrouds the building, creating a sense of discovery or curiosity when approaching the entrance. • Emphasises the experience of transitioning between the two spaces. Value: 7

1b: Water falling onto the horizontally flowing water: • Creates connections between separate vertical levels, and punctuates the continuity of the horizontal flow by creating powerful moments of interest. • The impacts may give rise to small amounts of mist spray, bringing the experience of ‘touch’ beyond the primary boundaries of the water flow. Value: 4 1c: Still water framing the tori gate: • Contrasts with the moving water channel that bisects the circulation path; hence complements the change in domain signified by the tori gate. • The stillness also complements the religious conditions of the space beyond; the water largely remains at the one location, similarly to the kami whose presence is implied by the gate. Value: 5

2. Overpass 2a: Water running along a circulation path (at the same level) • Circulation movement; see 1a. • The relation with the path below creates a moment of interest as a point of interchange. Value: 3 2b: Water running along circulation paths (at different levels) • Circulation movement; see 1a. • The relation with the path above creates a moment of interest as a point of interchange. • The shaded space below the upper path creates a shelter, that may serve as a respite or idling space. • The different levels allow for different perspectives of interaction with the water, and also maybe indicate a separate circulation channel for smaller water transports. Value: 3 CONSIDERATIONS for improvement/alternate experiences: Expanded spaces along the water edge(s) for idling activities that encourage the interaction or viewing of events associated with the water.

CONSIDERATIONS for improvement/alternate experiences: Could reduce the presence of the water channels along wall edges to allow people to approach and touch the wall, experiencing the sensation of touching a wall shrouded in water. Temperature could also be considered in this case. Walls of water (higher volumes of water), such as aquarium walls/tunnels/columns.

4. Water Terraces 4a: Still water terrace: • Individually, the water terraces are simple and calm; a pristine feeling can be observed from the stillness of the surface. Value: 2 4b: Moment of release of water into terrace below. • The moment of release is presumably quite a rare occasion; a short-lived event that momentarily engages the attention of those present, regardless of how beautiful they may find it. Value: 4 4c: Cascading water terraces: • Based upon the forms of rice paddies, the terraces recall the idea of agriculture and rural settings. • Stillness; see 5a. Small waterfalls; see 10c.

10. Small Garden

7a: Water channels: • Circulation movement; see 1a. • Small channel; see 5c. • The added koi (or other fish) create a stronger sense of nature and the ecosystem, granting some company to those walking by. Value: 4

10a: Water curtains: • Provides a sense of ‘soft’ separation between spaces; views or sounds are not prevented, but either lightly distorted or masked. • The meditative qualities of the falling waters complement the calmness of the garden space, and provide a soft sense of enclosure or refuge. Value: 4

7b: Pond: Pond; see 10b. • Unlike 10b, the approach is more interesting in that the channel leads people towards the pond, traveling through a narrow passage, which then expands upon entering the clearing/courtyard/ garden; a brief moment of tension and release. Value: 7 CONSIDERATIONS for improvement/alternate experiences: Using channels for drainage systems ( in conjunction with roof systems). Creating moats around different buildings/subjects/ areas.

8. Water Corridor 8a: Water ceiling/enclosure: • Experiencing refracted sunlight; the distorted light waves and their dynamic patterns. • Soft visual separation similarly to 10a, that helps enclose the corridor space. Value: 7 8b: Waterfall walls: • Water curtains; see 10a • Together with the ceiling, the water systems enclose the corridor separating the space from the outside, providing a sense of privacy and protection without obstructing natural light from entering. Value: 6 CONSIDERATIONS for improvement/alternate experiences: Potential to design other refracted effects, and also coloured light effects.

9. Stairwell 9a: Stairwell water feature: • The verticality of the water complements the vertical movement of the pedestrian circulation. • The water creates activity in the empty space in the center of the stairwell, and draws the eye up/ down the space. • The low intensity complements the deliberate ascent/descent of stairs, which are often a more humble alternative to faster modes of vertical transport like escalators/elevators. Value: 6

10b: Water pond: • The calmness and scale of the pond complement the garden as a meditative space. • The pond and garden support an ecosystem that gives more life to the space. • The bridge allows for and encourages more intimate interaction with the water, also from a different perspective. Value: 9 10c: Waterfall: • The waterfall provides a specific moment of interest in garden which can be observed and appreciated (and occupy/clear the mind), and also further masks out external distractions from the space. Value: 4

11. Elevated Water Channel 11a: Large elevated water channel: • Experiencing the environment outwards from or atop the water rather than towards the water from outside. • Larger volumes of water carry more gravity; more authority. Value: 8 11b: Horizontal water strip below: • See 1a 11c: waterfalls: • See 1b CONSIDERATIONS for improvement/alternate experiences: Using these higher volumes of water, allowing activities like swimming. Creating space for activities along the water edge. The potential scenery and views along the channel Explore more river experiences: river banks, beaches, river networks, river markets, rivers that spill over etc.

CONSIDERATIONS for improvement/alternate experiences: Create experiences around condensation. Explore the moment where the drips contact with the water (or other surfaces) below.

Design Proposition

Tokyo was once a city of water, and it was an integral part of the city. Life was orientated around the water systems of canals and rivers - it connected people to their place and environment.

Second World War when â&#x20AC;&#x2DC;rubble of the bombed buildings was used to fill in small waters in the cityâ&#x20AC;&#x2122; (Graaf, R. and Hooimeijer, F., n.d. Urban Water In Japan).

The disappearance of the waterways began during the Showa-Era and the

The proposition for this design is to relieve Tokyo from the pressure of urban

sprawl, and regain and preserve its existing rivers and environs. It attempts to reconnect the relationship of water to its community and city.

Nihonbashi (Edobashi) in the Edo Era, served as a major connection point with its road networks (Gokaido), river and canal system playing a central part to the economic growth in the Edo period. Nihonbashi was a place of interaction, exchange giving rise to new industries

and cultures. In the latter half of the 1990s a significant increase in population emerged and for a decade from 1995-2005 the Nihonbashi area was designated an emergency urban renewal development (Tsubomoto, Uozumi and Wakabayashi, 2012).

Tall condominiums were developed, and the private sector lead the redevelopment. Large high-rise towers with proposals reaching up to 287m and occupying entire blocks.

The city’s population boomed (shortly after being renamed to San Francisco) due to the discovery of gold in 1848, and so the urban grid was largely designed to accommodate in the influx of people due to the gold rush.

DESIGN LAYOUT & PRINCIPLES

The grid is primarily comprised of two orthogonal grids that meet along the diagonally-running Market Street, which was first laid out in a survey by Jasper O’Farrell in 1847. The grid is noticeably regular, and is quite compact in the downtown area to the Northeast above Market Street, with smaller alleys and laneways being more prevalent.

Another noticeable feature of San Francisco is its irregular topography, upon which the grids were overlayed. As a result the streets undergo significant changes in elevation that are not indicated by the grid. However, around the Twin Peaks in the centre of San Francisco, the regular gri has been disrupted to accommodate the more extreme topography.

VILLA EL SALVADOR In 1971, the government surveyed and divided up a large piece of vacant land south of the city of Lima, offering lots without services to any family in Lima that needed housing—a type of development which came to be called a barriada asistada (assisted shantytown). These lots were organized into “residential units”, groups of several blocks that featured a central plaza to ensure the presence of public space and to create a natural scale for community organization. Originally, Villa El Salvador consisted of only government produced, surveyed plots - a chalk grid drawn in the sand. Each standard group of 16 blocks is 300 by 300 meters and is centered around a public plaza, many of which have now fallen into disrepair. This necessitates immediate attention in order to improve the quality of life in Villa El Salvador.

Villa El Salvador zoning plan.

An irregularly divided block, still following the naming principle.

Villa El Salvador was conceived as more than just a residential neighborhood. It was planned to have three major programmatic zones - residential, agricultural, and industrial - which allow for future urban growth using the grid as a framework. The houses, in turn, were grouped into 24 lots, organized in 16 blocks, which formed a residential group, which reserves a central communal area where the inhabitants built an initial education center, a communal premises, a medical post, sports areas and recreational.

The coding system is based on the complexity of the space, such as architectural elements, human activities, trees and objects. The wiring system create another layer of nodes and links, which increases the spatial complexity. The rhythm diagram shows that the excitement of city is quite flat.

Based on Camillo Site Theory, some interplay between stimulation and temporary relief are placed to improve the excitement according to the wiring connections. Another layer of circulation and public spaces is proposed to increase the connectivities. The rhythm diagram reflects the interplay between stimulus and relief as well as the increment of excitement.

TOKYO Ginza 銀座 Ginza is a district in the Chou Ward of Tokyo, Japan – its 87 ha and is well known as a popular shopping district. Ginza was developed during the Meiji Era (1868-1912) to become westernized. Hence it has a distinctly strict grid set against many other districts of Tokyo with irregular and interlocking street networks.

DESIGN LAYOUT & PRINCIPLES

The implementation of this current urban model was implemented in 1872 by a British engineer Thomas Waters, where the intension was to develop a traffic efficient city with large thoroughfares and boulevards. However despite planning large urban blocks these blocks can be broken down to many sub blocks subdivided by secondary streets and tertiary street networks. The scale relationship dynamic between small alleyways and tall and smaller buildings in large blocks is a fundamental character of the Ginza grid.
