Juna Restaurant sits on Jalan Arjuna, Ubud, on an elevated site. The plan follows the land’s contours. Spaces are arranged to frame internal views and a west-facing outlook toward the river and rice fields, bringing the landscape into the dining area.

The project is grounded in vernacular construction practices, details, joints, and roof craft, paired with a contemporary bamboo architecture approach. In a dense, built context, a central circular plan establishes a clear human scale and creates an internal opening for light and air, a central relief. Had the roof converged to a single apex, the interior would feel enclosed, and the structure would demand an excessively tall roof. Here, the roof instead steps and vents toward the middle, directing rainwater to a central point while maintaining openness at eye level. The structure combines a series of arches with an A-frame that defines the enclosure.

The primary structure is bamboo. A skylight uses SolarTuff panels on a steel frame, finished to blend with the bamboo and provide a flat, watertight surface. The roof is finished with Ulin wood shingles, executed by local craftsmen, integrating local techniques within a contemporary system.

Passive strategies drive performance: an open plan and a ventilated roof gap support continuous airflow and allow hot air to exit naturally. The inner courtyard improves daylight and cross-ventilation. A central pond, abundant planting, and controlled air inlets work together to mitigate heat and improve thermal comfort. Water is managed with an on-site deep well and elevated storage, enabling a gravity-fed supply and reducing pumping.

Inside, large openings maintain airflow and daylight. The kitchen, bar, and dining were coordinated with restaurant operations to ensure efficient service and a close connection between staff and guests.
