Located in suburban area of South Jakarta, Rumah Sisik Batu—translated as a house with stone scale (or skin)—is a recently finished renovation project by ArMS. Prominent use of basalt as the building envelope is evident even at the house’s parking space and a security post located at the front. Muhammad Sagitha of ArMS pointed out that the inspiration behind the project’s name was from the angled and layered arrangement of basalt pieces that resembles animal scales.
