PROGRAM & COURSE:

RMIT University - Master of Architecture.

Architectural Major Project (Thesis).

CONTRIBUTION:

Concept & Schematic Design, Graphics & Illustrations, Visualizations.

“Kampung Raya” (or the Celebrated Village in Indonesian) seeks to develop an alternate high density urban typology for the city of Denpasar (Bali) in Indonesia, seeking to explore how can an incremental architectural intervention, specifically Public Housing can operate as an “infrastructure” within the city.

01

The project accommodates nearly 900 residents and residential units at a densely-tight site and it is built adjacent to the public amenity spaces in between the units and uses accessories as a typological component, specifically porosity and protection to adapt to its climatic conditions whilst keeping its indigenous spatial quality from the ‘Warung’ typology.

The Falcon Civil Hangar is designed for maintainance and storage for commercial private jets and fighter jets. It occupies 5 jet planes with office and community spaces at the rear end of the terminal.

The process undertaken was to follow the requirements

02

known as FRD (Facilities Requirement Document.), which specifies requirements and design types of the hangar.

The work undertaken is under coordination of architects and drsfters from Wisana Matra Karya based in Jakarta, Indonesia.
