Kongjian Yu, Creator of the Sponge City Concept, Passes Away in Brazil Plane Crash

Kongjian Yu, the pioneering Chinese landscape architect and urban planner credited with coining the "sponge city" concept, has passed away at 62. According to Reuters, he was killed in a plane crash on Tuesday in the wetlands of Mato Grosso do Sul state, in Brazil, while reportedly filming a documentary about his work, after being featured in the opening program of the São Paulo International Architecture Biennale last week.
A globally-recognized advocate for ecological urbanism, Yu gained international relevance after his "sponge city" philosophy was adopted as a national policy in China in 2013. The approach prioritizes nature-based solutions, such as wetlands, parks, and permeable pavements, to absorb and retain water. This novel method stood in stark contrast to traditional concrete infrastructure, offering cities a way to combat urban flooding and accelerate climate change by working with nature rather than against it. His ideas have since been implemented in hundreds of cities worldwide.

Form Follows the Existing: 15 Homes Designed to Preserve Local Trees

The preservation of the environment and the harmonious integration of the built and natural elements are fundamental principles in contemporary architecture. Various design strategies are employed to achieve this balance, ranging from the revival of vernacular techniques to the use of advanced technologies. However, this concern goes beyond the choice of specific construction systems or innovative materials; it also manifests in the design approach that ensures the preservation of the site's natural elements. In this context, we present 15 homes designed to protect local trees, showcasing how architectural decisions can adapt to nature rather than impose on it.
