A series of monumental spiraling structures with vaulted roofs and balconies overlooking a 45,000-square-meter site in Sibang Kaja, Bali, is an innovative foray into sustainable architecture. Designed by IBUKU back in 2008, “Heart of School” is made of local bamboo and grasses that once deteriorated, can be easily removed, composted, and replaced with similar materials. The multi-story structure features thatched roofs evocative of coiled nautilus shells that sit atop three, open-air towers. It houses a high school and its administration and was a catalyst for Bamboo U, which offers courses in architecture and design using the woody material.
“Heart of School” is also included in Build Better Now, a virtual exhibition highlighting 17 inventive projects working to combat the climate crisis. “Globally, CO2 emissions from the building sector are the highest ever recorded, with buildings and construction responsible for 38% of total global energy-related CO2 emissions,” a statement says. The exhibition promotes alternative, sustainable methods, and other projects include a low-carbon home made with 3D-printed clay, an “urban ecovillage” in São Paulo’s Jardim Nakamura favela, and bridges constructed with laminated timber in Amsterdam.
