Investigate Sustainability Aspect in Spatial Configurations of Javanese Vernacular Architecture: Case Study of Joglo House

This research focuses on the unique spatial designs and variations found in the Joglo houses of Juwana, Pati, in Central Java, a region celebrated for its indigenous architecture. The Joglo house, a fundamental component of the Javanese cultural identity, is often inherited through generations without any formal written records, leaving its architectural details in scholarly discussions. The purpose of this study is to explore the spatial characteristics of spaces in the Joglo house that support the sustainability. The study employs the space syntax methodology to investigate the spatial interrelations among rooms in 16 Joglo houses then the 5 representative houses were picked to be analysed mathematically. By using the justified plan graph analysis, it identifies specific patterns and categorizations in the relationships between rooms, thereby uncovering the intrinsic architectural principles. The findings reveal that all the representative floor plans have a corridor as the most integrated space and there is a distinct separation between public and private spaces. This study bridges traditional knowledge and scholarly research, highlighting the intricate architecture and cultural significance of Joglo houses.
