Inspired by Indonesian cast rice dumplings known as Ketupat, the Kopo house mediates a difficult site and creates locally resonant space.
Bounded by a highway, factory and motorbike dealership the Kopo House site provides a challenging context for a residential project. To detach the domestic space from its immediate chaotic urban condition, the house internalized all available exterior space forming a series of courtyards and rooms surrounded by seven-meter- high walls. Given the severity and opacity of the home’s exterior surface, strategies were adopted to soften, puncture and reduce the scale of the concrete walls.
Local bamboo veneer mats or “Bilik” were used as flexible formwork to create openings and pattern the surface of the concrete. Parametric software and CNC cutters were used to create a ruled surface molds for forming openings. Through a series of drawings and prototypes the novel techniques for casting were translated both through digital machines and manual craft.
