This week's architecture news covers a range of projects addressing the changing needs of cities, from the adaptation of existing sites to the development of new cultural and public spaces. As Antalya prepares to host COP31, projects in Rotterdam and Pittsburgh focus on the renovation of established cultural institutions, while developments in Copenhagen, Chicago, and Tbilisi explore new approaches to recreation, public access, and urban regeneration. Elsewhere, Foster + Partners has revealed plans for a mixed-use development in Yerevan, VG13 Architects has won the competition for a new stadium and sports district in Zagreb, and Aria Property Group has unveiled a residential and public precinct in Brisbane ahead of the 2032 Olympic and Paralympic Games.

The Human Shelter: Expedition into What Makes a Home is an exploration of the feeling of home. Directed by Boris Bertram and funded by IKEA, the film looks at present ways of living in Norway, Iraq, the United States, Nigeria, Japan, Uganda, and Iceland, interrogating the role of home in order to project it into the future. Through imagery and personal narratives, the documentary connects the concept of home with landscape, movement and settling, time, migration and security, vulnerability, and nature. How do displaced populations create a home? When does a shelter become a home? Portraits, stories, and shelters across four continents give viewers a glimpse of an answer to these big questions in a one-hour film tour.

Direct contact with a material allows one to appreciate textures, compare finishes, and observe how its appearance changes under different lighting conditions. At an exhibition, these possibilities are complemented by exchanges with manufacturers and professionals, helping to understand applications and resolve questions about their use. This relationship between material exploration and architectural practice was one of the central pillars of the seventh edition of Obra Blanca, which drew more than 23,000 professionals to Expo Santa Fe in Mexico City.

Balsa Crosetto Piazzi is an architecture practice founded in 2015, based in Córdoba, Argentina, and Boston, USA. Led by architects Juan Manuel Balsa, Rocío Crosetto Brizzio, and Leandro Piazzi, the core of their work is the material side of architecture. For them, a building is not just a finished object, but rather a way to organize everything that goes into making it. Their work is shaped by a slow process; during the construction and design stages, they pay attention to where the materials come from, who does the work, what skills those people already have, and what's actually available nearby. This allows their built work to become a platform that serves as a starting point, bringing all of these pieces together. In that sense, they also describe their projects as opportunities to "deconstruct entrenched conditions."

An opening between two rooms shapes how people move through a building, what they see from one space to another, and whether an area feels connected or separate. Although doors are among the most frequently used interior architectural elements, their impact on the interior organization is often considered late in the design process. Yet their movement and relationship to surrounding surfaces influence circulation, furniture placement, and the perception of space.

In residential renovations, these decisions are particularly important. Existing walls, structural elements, building services, and ceiling heights can limit options, while new layouts often balance open-plan living with the need for privacy. In new construction, architects have greater freedom to coordinate wall cavities, suspended ceilings, and door mechanisms from the outset.

When the Ostrogoths besieged Rome in 537 AD, their first military act was to cut the aqueducts. Eleven gravity-fed channels supplied the city with up to a million cubic meters of water per day, more than enough to sustain a population of over a million, fill the public baths, and scour the sewers. Without the aqueducts, Rome became a fortified enclosure around a contaminated river, proving that water was essential to the city's existence.

Unlike land, which can be fenced off, or oil, which can be stored, water is a resource that nobody can fully own, yet everyone depends on. It moves through aquifers, across borders, and down rivers. The Romans were cognizant of this fact; as the aqueducts constituted public infrastructure, the water flowing into fountains was accessible to all. Frontinus, the administrator who oversaw Rome's water system in the first century AD, documented every allocation, every illegal connection, and every abuse of the system with the rigor of someone who understood that water management was a civic act. Architecture, in this sense, has always had the capacity to make water a common good, and equally, by the same means, a privilege.
