Design Concept
OSS (One Stop Shop), An administration office center, located in Koror State, Palau, is a contemporary civic building that consolidates governmental functions while staging a nuanced dialogue between Austronesian cultural lineage and modern architectural elements. The site fronts Bethlehem Park—an everyday gathering park for local residents—with a sports complex to the left and an outdoor baseball field at the back, forming an urban space that connects daily life, recreation, and governance.
Responding to the site’s fan-shaped open space, the plan unfolds in a radial, fan-like geometry. This deliberate outline subtly echoes the rounded form of Palau’s traditional currency, the Udoud, allowing the administrative office to be recognized as a cultural signifier and embedded within collective memory.
The project’s main architectural idea draws from Palau’s most emblematic traditional building type, the Bai. The design team transformed the Bai’s iconic triangular roof into a monumental main entrance—a soaring, triangular glass curtain-wall system. Through expansive glazing and skylights, the open ceiling space captures Palau’s saturated sunlight and the blues of its sky, bringing the island’s atmosphere into the interior. In this way, visitors entering a modern civic facility remain sensorially attuned to the rhythms of clouds and light. To further respond with the Bai’s raised platform typology, the building’s ground-level primary façade employs large, transparent triangular floor-to-ceiling glazing. This makes the upper volume—where the cultural symbolism is most concentrated—a sense of levitation, while also drawing daylight deeper into the public service spaces at ground level.
The exterior design is conceived as an architectural palimpsest—a three-dimensional storybook. Mythic animals, human figures, and allegorical motifs traditionally expressed in Bai are abstracted into a geometric symbols. Interlacing triangles and linear patterns across the façade and window grids, the design reconstitutes ancestral iconography as a contemporary architectural element. Moreover, acknowledging the Palauan tendency toward a horizontal, eye-level lived perspective, the open ceiling space is bridged at level 3 by skywalk that offers an elevated yet grounded view point from which citizens, even while attending to the OSS, can look out toward the vast blue ocean and Palau’s most precious natural asset.
Organized around the guiding principle of “centralized services, shared public realm,” the OSS forecourt supports civic events and everyday parking needs, while establishing a spatial dialogue with the park’s pavilion—rich in traditional architectural forms and motifs. As a civic threshold for gathering, the forecourt plaza extends into the OSS lobby to form a public area that carries forward local cultural memory, positioning the OSS as an active component of daily life.
