INTRODUCTION Slum as a landscape typology ‘Kampong’

in

bahasal

literally

translates to ‘urban village’. These Kampongs or informal settlements exist within the cracks of the greater urban environment. They are diverse, social economic micro cultures. They are slums. I believe that even though these settlements consist of shelter which could be considered within the realm of architecture, they also possess a unique relationship to landscape. They could be considered a typology of landscape. Adaptation, fluctuation, compression and expansion are all qualities of landscape. They are also all qualities of these settlements. These spaces are not stagnant, they move and flow with the forces around them. They are an extension of nature through the most basic needs of humans. They are not set in stone with a projected life span, they can last the life of the city and indeed become a city if given the opportunity.

The Asian mega city The Asian mega city has given rise to new a new urban typology that has never before existed to the extent that it does today. Urban population is at its greatest point in human history and if the trend continues the urban landscape will need to evolve just as rapidly. “In 1965 the urban population of Asia was in the order of 430 million, with 1.5 billion people living in rural situations. Today the urban population is about 1.2 billion, and by 2025 the urban population is projected to soar to a staggering 2.5 billion people�, (Robins & El - Khoury, 2004). These numbers represent a significant quantitative change to the human element of cities, yet to what extent have these mega cities begun to adapt to this human influx?

Past work positioning _ f2b design studio During F2B studio I was introduced to the design challenges of designing for high density urban environments that contain informal settlements. In this case the site was the city of Porto Alegra, Brazil. Early on in the attempt to understand the site from afar, -another design challenge that I was

We discovered examples of this economic pressure pushing on the established informal settlement within the city, and so, it became the main driver for the design project.

PROCESS Immersing as process Prior to first hand site experience my design outcomes were based on assumptions and researched theory. This was a fundamentally important process in discovering how to design for these environments. Designing from afar had a limited outcome in this context due to the human relationships that exist between the city and the sites. They exist so profoundly in experience that no level of reading can hope to deliver the intricate details that can be discovered. At this stage designs can be grounded through precedents and theory only. By taking the outcomes of this process to site, the gap between design proposition and

existing

site

relationships

became clear. By immersing myself into this environment, and being able to critically analyse my previous work, I was able to develop an approach that addressed the kampongs needs, and the cities at a variety of scales.

17


Original site

Petamburan is located west of central Jakarta. This particular settlement rests between two rail lines and off a major canal. It was my site for the first half of my research which dealt with the issues that came with designing from afar. I will aim to demonstrate my design strategies and offer analysis as to their level of success based on the second stage of my research process.

18


Design reflection

Phase I Armature Considering

the

theory

of

Kim

Dovey in Becoming Places, “There is a tendency to target high profile settlements that are visible from major transport routs for eviction� (2010, p83), and the armature design method from Elemental, I was able to determine a starting point for a design intervention. Focusing on the temporal nature and location of the settlement I began to develop my design focusing on, on-site resettlement and personal construction.

19


This idea of building armature and separation proved strong enough to further develop. The programs that it could support, location and its form would need to reflect existing relationships on the ground. At this stage the design is still functioning singularly. By this I mean there is yet to be any consideration of conditions and needs outside of this site. By taking this idea of the armature and understanding

Phase II Flood as opportunity. Flood as opportunity was in response to the architectural approach taken in ‘Armature’. The desire to use landscape as a driver was fundamental to this design. Though the site would not facilitate this design, the overlays that start to happen are an important step in understanding relationships between,

typologies, site and people. 22

23


Phase III Water When it Matters. Water when it matters was driven by the need to have an immediate impact on the established settlement. The intent for the design was there, yet the inability to understand the existing conditions on the ground makes the design more conceptual that practical.

24


1.

‘Water when it matters’ is an excellent example of design that arises from a theory and assumption. The area where this design is located is a kampong that is over 150 years old. It is established and has adequate access to tanked water as well as public toilet infrastructure. The micro

Intent My approach aims to demonstrate that the cultural, social and economic opportunities that exist within the poor social class are fundamentally important to the city. The existing relationships that exist, no matter how foreign, need to be considered as an integral and unique opportunity to help inform design. A bottom up design approach, with a desire to rethink existing infrastructure and that understands the social requirements of the population is the foundation for the adaptation and transformation of the urban environment.

When asked where he would relocate once evicted his response was unsure. 5. Charity funded school located through the wall, offers free education and support to families and children. The location is fixed reducing the number of children that can benefit from the program.

2030 Indicators The great equalizer of Jakarta is the traffic. This is of high priority within the spatial master plan, with Olivia Stinson suggesting in Expat Indonesia that “the city could reach total gridlock in the streets by 2016” (2010, p36). To

The question that presents itself is whether the new rail system will become a replica of the existing relationships that exist in Gembrong Gaplok or if a ‘new’ typology can create opportunity not just for public transport but for housing, access, networks and economies of the informal nature.

Cross flow, by this I mean the ability of a person to traverse the rail line at the perpendicular is vital to this design. The reduction of the ‘channel’ effect allows for people to cross more often without the existing situation of enclosure being felt.

Luar Batang 1. The edge of the kampong is the youngest, and often the least established. However the ability to attach to the ‘body’ is a clear accelerant in establishment. This image gives some indication into the reliance on bamboo that exists within Luar Batang. 2. Entry into the Kampong is directly off the market space, most residence work and live within Luar Batang. This walkway operates as a walking ‘plaza’ with everything that one would need, and often not need to live. Cloths, school books, food, water.

3. The old port area is a hive of activity; many marine industries still operate here. Everything from fishing, boating supplies to seafood and other stalls deemed necessary for the environment. 4. Offsite micro economies are strong within Luar Batang. These are fishing boats with a port tour operating in the back ground. These industries are informal, yet are vital to the city.

5. Religion is extremely important within every culture. Here is an ad hock mosque that is located within the heart of the Kampong.

2030 Indicators

Luar Batang

The Jakarta 2030 spatial master plan indicates a strong desire and intent for more open green space within the city. As indicated on the plan (above left) several zones have been selected for this endeavour. The Luar Batang region is set for some dramatic change. If this vision is realised, a huge amount of new land will come available for water front living for the middle to upper income bracket. This in its nature is well out of reach for the majority population, new land will become green space at huge expense whilst existing open space will be given over to public warehousing,

The spatial plan ‘map 43, Priority Area for Specific Planning Policy’ gives a black and white indication of intent regardless of existing cultures, economies and social networks.

Conclusion The fact that this project evolved into more than just a exploration in design, which for me was the initial aim, is something that I am still in the process of coming to terms with. My involvement with Jakarta Hidden Tours, Ronny and his partner Anika has is many ways added another rich layer to this research. The design of the Education Garden within the Ciliwung Kampong is just as much a thank you to them as it is a response to my understanding of that site. Opportunity

The Ciliwung Kampong presented, to me, an amazing opportunity to help Ronny have an even greater impact through his work. In many ways I am adding to the foundations that he has already laid, but this is what good design does, it works with the existing, not against.
