Batang House stands as a reimagined model of tropical living in Northern Central Java, Indonesia. Built on an 8 × 12-meter plot within a standard housing complex, the project began with the demolition of an existing structure compromised by poor construction. The rebuild became an opportunity to rethink how a compact site could respond to the region’s hot and humid climate. Located on the northern coast of Java, Batang Regency experiences intense sunlight and high temperatures throughout the year. Thermal comfort, therefore, became the central design driver. We approached this challenge with a clear strategy: to minimize heat gain while maximizing ventilation and daylight within limited site constraint.
The facade employs a predominantly white palette and reflective materials that deflect solar radiation, drastically reducing surface heat absorption. Dark tones and black finishes were intentionally excluded from the façade to prevent heat retention. Instead, vent blocks form a rhythmic second-skin layer, where it becomes an architectural feature that doubles as a privacy screen and a natural ventilation system. This porous façade filters sunlight, channels air circulation, and softens the boundary between the home and the surrounding neighborhood.
Despite the limited footprint, Batang House achieves a sense of openness through spatial manipulation strategies. Gaps between the main walls and the perimeter envelope facilitate continuous airflow, while large openings, skylights, and voids invite natural light deep into the interior. This interplay of light and shadow dissolves the line between indoor and outdoor spaces, making the house feel larger and more connected to its environment.
Inside, a restrained palette of darker tones intentionally placed to provide visual calm and to reinforce a cooling effect. The interior design aims to balance modern minimalism with tropical warmth by integrating natural textures, clean lines, and a sense of quiet luxury. Every space serves a functional purpose without compromising visual harmony or climatic performance.
