Co-habitation Space: A Model for Urban Informal Settlement Consolidation for the Heritage City of Yogyakarta, Indonesia

Yogyakarta City has a sacred cosmological space formed by imaginary philosophical axes based on the centuries′ old Javanese belief system. The Kraton or Sultan′s Palace is the focal area with the space around the philosophical axes functioning as a buffer area, and the outer circle that serves as a supporting area. All are linked by the concept of co-habitation space. This paper aims to explain the spatial, philosophical principles in relation to the phenomenon of changes in the urban space in Yogyakarta today. The concept of co-habitation space is physically understood as activities showing guyub (harmony/togetherness) carried out by urban citizens. These can be seen from place attachment, livelihood, and spatial territory. The focus of this research is the sharing phenomenon (′co′) that takes place in kampong (urban neighbourhoods) spaces and their surrounding areas. This study uses a rationalistic approach and mixed methods of which the main methods employed were observation and space syntax. The results of this study suggest that the level of guyub in an area is influenced by the local spatial configuration. This study concludes that the concept of co-habitation space affected the way the Sultans of Yogyakarta utilized their kingdom′s territory for the welfare of their people.

Green Modular Concept of Sustainable Kampong Cityblock in Indonesia

The change in housing form from landed houses to more than 20-story high-rise apartments that prioritizes the aspects of a high efficiency often no longer considers the aspects of habitation culture. Kampongs as a form of urban vernacular settlement that has a habitation culture of close-knit neighboring culture are very vulnerable against high-rise urban living culture. This paper aims to analyze the process of the habitation culture transformation through green-modular approach. The green approach used in this model involves sustainable design principles of ‘co-habitation architecture concept’. The neighboring behavior of kampongs with a very close neighboring culture needs to be approached by using sustainability principles in the context of high rise kampong cityblock architecture. The concept of co-working responds to the needs of social interaction; co-benefit concept responds to the needs of accommodation to support informal economic activities; and co-exist concept responds to the needs of harmony for tropical architecture that utilizes a combination of natural thermal comfort system and artificial thermal comfort system. Meanwhile, the modular approach used in this model involves the principle of space efficiency coordinated in modular system and space effectiveness principle that can respond to the needs of interaction space. The variations of organic living units connected through a corridor system with pocket space are hoped to be able to accommodate neighboring culture and informal economic activities in a modular space coordination system.
