Xu Tiantian is the founding principal of DnA_Design and Architecture, an interdisciplinary practice that addresses both the physical and social dimensions of the contemporary living environment, across scales. Born in 1975 in Fujian, China, she received a Master of Architecture in Urban Design from the Harvard Graduate School of Design and a bachelor's degree in architecture from Tsinghua University in Beijing. Her recent work focuses on rural revitalization through a strategy she describes as "architectural acupuncture," understood as small-scale, site-specific interventions designed to activate local culture, agriculture, and tourism. These interventions, primarily concentrated in China's rural regions, have been recognized by UN-Habitat as a global model for urban–rural integration. In this interview with Louisiana Channel, she reflects on the role of the architect, questions architecture itself and the concept of beauty, explains her working methodology, and emphasizes the spatial dimension of nature.

The most innovative and impactful design projects arise from the intersection of different fields. The architecture community has always borrowed from, or been inspired by, other forms of cultural production such as film, photography, literature, and theatre. In the theatricality of Baroque churches and the cinematic sequences of contemporary museums, architects have looked beyond the building itself to understand how space can shape a story and construct an experience.

Worldbuilding takes this one step further. Instead of designing only the architecture of a place, it asks architects to establish the social rules, narratives, technologies, economies, atmospheres, behaviors, and relationships that make that place believable. Rather than beginning with, "What should this building look like?", worldbuilding suggests beginning with, "In what kind of world would this building make sense?"

What makes a building worth preserving? Age is the most common answer, but not always the best one. A building from the 1950s or 70s may carry as much historical significance as a medieval cathedral; it simply demands a different framework, one that weighs political context, cultural meaning, and architectural innovation over the mere passage of time. This is especially true for modernist architecture across the so-called Global South, where the movement took on unique forms of expression.

It is precisely this conversation that ArchDaily and World Monuments Fund are now opening together. WMF brings on-the-ground conservation expertise across the world, and ArchDaily brings the editorial capacity to contextualize that work and connect it to a global audience. The goal is to do both at once: preserve places and tell their stories, shaping how modernist heritage is understood far beyond the field of preservation itself.

Architecture this week reflects on how buildings and cities adapt to changing cultural, social, and environmental conditions. From the expansion of established institutions and the preservation of architectural archives to new approaches to housing and the use of domestic space, several stories consider how architecture negotiates between existing contexts and future needs. These questions extend beyond individual buildings, touching on the role of public space, infrastructure, energy, and collective memory in shaping the built environment. At the same time, new projects and cultural programs across different contexts demonstrate how architecture can respond to local histories, urban transformation, and resource constraints while establishing new relationships between buildings, landscapes, and the communities that use them.

The origins of the Copenhagen Architecture Biennial trace back to the establishment of the CAFx yearly festival in 2014, which was renamed Copenhagen Architecture Forum in 2024 to lead new projects focused on architecture and urbanism, such as the shift from festival to biennial, with a first edition in 2025. Today, the details of the second edition are being announced: it will take place from September 9 to October 15, 2027, under the theme "Elements." After the Biennial's inaugural call to Slow Down, the event is turning its attention to the planetary elemental forces that architecture has sought to master and prepare to inhabit, questioning one of modernity's most persistent promises: control over the environment. Activities will be dedicated to and organized around each of the four elements: fire, earth, air, and water, including an open call for pavilions, exhibitions, and a symposium.

Architectural ornamentation has been a recurrent subject of debate across the industry for decades. A practice that was largely abandoned during the Modernist movement could now be standing on a platform that might, again, allow its resurgence, due to the current convergence of robotics, artificial intelligence (AI), and digital fabrication. Technology has seemingly removed the primary obstacle to decorative detail: the high cost of skilled manual labor. However, this new technical capacity demands a critical examination: What does ornamentation truly represent, and what do we gain or lose by resurrecting it through algorithmic design?
