RAD+ar punctures arched facade to protect office building from jakarta's humid climate

RAD+ar protects workspace building from jakarta’s humid heat

In West Jakarta, RAD+ar (Research Artistic Design + architecture) completes the Sagehaus Office Garden, a high-density working space designed to stay naturally cool despite the humid heat of the city. The project serves as the headquarters for an athletic sportswear brand, packing flexible workspaces, creative social zones, and a rooftop gym into a 2,000-square-meter building that channels Jakarta’s breezes through its very structure.

At the core of the design is the Dome for Wind, a carved form that directs airflow across shaded gathering spaces, breezeways, and garden terraces. The arched facade itself avoids direct solar gain by slicing and puncturing the surface rather than relying on conventional shading systems.

To handle the climate, the Indonesian RAD+ar team uses a mix of passive strategies. These include thick thermal mass in the main public spaces, strategic staircases that encourage walking over elevators, and large carved facade openings designed to capture light without trapping heat. The breezeways and garden restrooms are key to comfort and energy efficiency, offering staff a cooler, more pleasant environment while minimizing reliance on mechanical cooling systems. Even the high-security file room, tucked deep in the center of the floor plan, benefits from this layered, breathable approach. The rooftop doubles as a gym and recreational garden, providing a flexible outdoor space that strengthens the commitment of the building’s program to wellness and sustainability.

Three horizontal zones define the layout, starting with a ground level for social and creative activities, controlled office spaces in the middle, and a flexible rooftop garden above. This stacking of functions maintains an open, adaptable atmosphere without compromising security or work efficiency. Across the site, public spaces, meeting rooms, lounges, and leisure zones are layered to encourage movement and casual interaction throughout the day.
