Barcelona has just become the first city in the history of the UIA World Congress of Architects to host the event twice. Thirty years separate the two editions, and the distance between them says as much about architecture's changing self-understanding as anything spoken from a stage. In 1996, the congress placed the city at the center of the debate, consolidating a post-Olympic urban model that would go on to be studied and contested for decades.

In 2026, under the theme "Becoming. Architectures for a Planet in Transition," Barcelona hosted a very different conversation. The congress's curatorial team — Pau Bajet, Mariona Benedito, Maria Giramé, Tomeu Ramis, Pau Sarquella, and Carmen Torres — organized the program around six thematic lines: Becoming More-than-human, Becoming Circular, Becoming Embodied, Becoming Interdependent, Becoming Hyper-Conscious, and Becoming Attuned. As they told ArchDaily ahead of the opening, the premise behind this structure was that most architectural decisions are, in practice, very specific — which material is used, what is demolished or preserved, how much water or energy a building consumes — yet those specific decisions carry planetary implications.

For most of the twentieth century, architecture has learned to read cities through roads. Street hierarchies define urban plans, intersections organize movement, and buildings are understood by the façades they present to sidewalks. Roads appear so fundamental to urban life that they are often mistaken for a universal condition. Across much of Southeast Asia, cities developed according to an entirely different spatial logic. Long before automobiles reordered urban landscapes, rivers served as streets, marketplaces, civic spaces, and public infrastructure. Movement occurred primarily by boat, commerce unfolded along waterfronts, and architecture addressed water rather than asphalt. Reading these cities through their waterways changes how architecture itself is understood. Infrastructure, in this case, is not the road but the river.

Bamboo is often praised before it is understood. It grows quickly, carries a long history of building cultures, and appears to offer architecture an immediate ecological language. In photographs, it can seem almost self-explanatory: light, natural, renewable, and already aligned with a more sustainable future. Yet this apparent clarity is also what makes bamboo difficult to discuss with precision. Once it becomes a symbol of environmental responsibility, the material itself can disappear behind the image it produces.

This is the risk of bamboo's contemporary revival. It can be imagined too easily as a green substitute for industrial materials, a regional atmosphere, or a softer alternative to the harder languages of steel and concrete. In each case, bamboo is admired before its conditions are understood. The more important question is not whether bamboo is sustainable in a general sense, but what kind of architectural culture it requires: what forms of knowledge, maintenance, regulation, labor, and time are needed for its sustainability to become real.
