As cultural institutions advanced major preservation projects and new demographic data reframed understandings of urban growth, this week's architectural discussions centred on how cities and museums adapt to evolving social, environmental, and infrastructural conditions. Efforts to safeguard modern heritage, developments in long-term urban planning, and reflections on architectural legacy intersect with global observances such as the International Day of Persons with Disabilities, highlighting the ongoing need for more inclusive and accessible environments within the built landscape.

Jakarta has become the world's most populous city, according to the World Urbanization Prospects 2025 released by the United Nations Department of Economic and Social Affairs (UN DESA). Using an updated and harmonized method for defining urban areas, the report estimates Jakarta's population at nearly 42 million, placing it ahead of Dhaka, which is about 40 million, and Tokyo, 33 million. The revised ranking illustrates how updated measurement criteria and continued demographic growth are reshaping understandings of urban scale in Asia and globally.

Public spaces remain some of the most dynamic sites for unbuilt architectural experimentation, revealing how cities and architects can imagine accessibility, gathering, and civic identity. In this curated Unbuilt edition, submitted by the ArchDaily community, the selected proposals examine parks, pedestrian corridors, cultural landscapes, and open-access urban environments that invite people to meet, move, rest, and participate in collective life. Rather than treating public space as leftover terrain, these projects position it as essential infrastructure—shaping urban health, memory, and social interaction.

The Indonesian parliament has approved a bill to relocate the capital from the city of Jakarta to a completely new city to be built on the island of Borneo, 1,300 kilometers from the current capital. The decision, first announced in 2019, comes as a reaction to the myriad of challenges faced by Jakarta, including pollution, traffic congestion, and, perhaps the most threatening, rising sea waters. As a consequence of excessive groundwater extraction, rapid urbanization, and rising sea levels, 40% of the city is currently below sea level, making it increasingly difficult for the infrastructure to protect the residents. President Joko Widodo proposes an alternative: relocating the administrative center of the country to a new green metropolis, to be named Nunsantara, meaning ‘archipelago’ in ancient Javanese.
