To maximize high quality space in the kampung, a reorganization of functions and locations is necessary. We have a focus on open spaces and different strategies are used to increase the amount and quality of these spaces. We made examples of how open spaces in the kampung could be transformed. An open space could either be strengthened as a green space, or used as a site for a high density building. Weak housing structures would be given new use, for example as a base for a garden, that would work as flood protection for houses. We propose high buildings along the depot and towards the river, to create open alleys between water and street.

River strategy: The main approach was to redefine a new edge removing the vulnerable settlements along the river, widening the riverbank and implementing new greenery. The river should also be activated as a transport line where goods and people can be transferred within the whole kampung. Land strategy: The site was divided into three layers – a new hard edge on the southern Part of Bukit Buri, a transportation backbone in the centre and e quiet green belt along the northern river side. Existent qualities in Bukit Duri were strengthened. The activities of workshops, shops, carpentries and traffic were enhanced. The old railway depot has been reactivated as a train station, the workshops densified and a new flexible building structure  is planned.

The concept for the section evolved directly from our terraced unit. The terraces were extended and used as a an artificial topography creating different situations to meet, to sell local products or just enjoying the river scenery on different levels. Establishing versatile visual conjunctions was a very important issue for the concept. On the right side the section is more urban with integrated small shops inside the volume of the terrace system. On the lower levels these shops can be directly tied to the use of the river. Fish and water related agricultural products can be sold here. On the left side of the section a series of terraced gardens are leading down to the river. The soil is stabilized through brick or concrete walls and the vegetation of the gardens. The walls lineary run along the river serving as flood breakers and pathways. The accessibility of the river is on both sides guaranteed through a simple wooden footbridge structure. Here we wanted to make the river less deep so artificial fish ponds can be installed.

The organisation of the block is characterized through an orthogonal grid based on the messurements of the unit. The grid is 2.7m in square with small internal streets of 1.35m width. An important aspect was to preserve the feeling and atmosphere of the original block system by evolving its organisational structure. An important inspiration was the competition entry for a housing estate in Previ, Lima by Atelier 5 as well as the Siedlung Halen near Bern. Both projects operate on small scale level creating high densities and a variety of high quality outdoor spaces. In both projects the preservation of a human scale in architecture was essential. Even when the unit operates autonomous in term of water supply and grey water treatment, on block level we did organise communal water ponds for rain water collection. Through a drainage system these ponds further water the gardens. The composting toilets serve as sanitary installations for the bigger block.

The attempt was to create a simple, modular structure by using local materials. The newly designed unit had to match the vernacular appearance and the scale of the built homes in the kampung. The module is based on a grid of 2.7m in square. This represents one living unit which can be multiplied in every direction, horizontaly and verticaly. The strucuture is a simple column construction, where each ceiling is flexibly fixed in between them.To react to the flooding, we decided to provide multiple ceiling levels. Starting with a terrace where the building is grounded on, this topic is continued inside the building as well. That way the people always have a way to escape the flood to the next storey. On top a terrace with an additional unit provides shelter in times of extreme flooding.
