In 1972, Robert Venturi, Denise Scott Brown, and Steven Izenour published Learning from Las Vegas, challenging architects to reconsider the underappreciated, largely dismissed commercial landscape in the United States. Their storied distinction between the "duck," a building whose form communicates its meaning, and the "decorated shed," an ordinary structure whose identity is conveyed through signs and symbols, questioned a widely accepted modernist assumption that architectural expression should emerge from form and function. By examining billboards, neon lights, casinos, and the commercial strips of Las Vegas, the authors argued that architecture should study the visual languages of American consumer culture.

A bayou is a slow-moving body of water, typically a creek or river that winds through low, flat terrain in a broader wetland landscape. Found throughout the Gulf Coast, bayous are distinct from swamps, which contain forested wetlands characterized by standing water, and from marshes, where tall grasses and herbaceous plants grow in saturated soils. The currents of a bayou landscape support biodiverse ecosystems of plants, trees, insects, birds, and fish, while the shifting water levels, saturated ground, humid air, heavy rainfall, and long, hot summers create a blurry environment between land and water, wet and dry, interior and exterior.

In Europe, cities are confronting the challenge of adapting existing urban conditions to a changing climate and warming summers while improving access to nature, quality public spaces, and the resources of everyday routines. ReGreeneration, a Horizon Europe initiative working across nine European cities, approaches this challenge through urban renaturing at the neighborhood scale. Combining strategies for complete neighborhoods, communal spaces, and nature-based solutions for cities, the Barcelona project examines how climate adaptation is embedded within residual, peripheral spaces of daily life. As part of a series following ReGreeneration across the participating cities, this article turns to Barcelona, where the project is working in the Trinitat Nova neighborhood to explore how small, often overlooked, urban spaces contribute to broader models of regeneration.

The landscape and scattered settlements of Ireland carry a reputation for wildness. Rugged cliffs meet the Atlantic, green fields roll across the interior, and rain and wind change the scene by the hour. A closer look reveals a worked terrain as historic stone walls divide agricultural fields, roads and paths connect towns to the coast, and castle ruins alongside cottages record centuries of occupation. Change is the expected condition of the island, shaped as much by human hands as by geology and weather, and the practice of treating the existing context as material to adapt and modify runs deep.

Ireland has a large inherited building stock, from vernacular cottages and farm compounds to Georgian and Victorian urban terraces, while a growing share of it sits vacant or derelict as housing remains scarce and expensive. Planning and heritage protections shape what can be altered, while growing attention to embodied carbon makes demolition increasingly difficult to justify. Under these pressures, design strategies for renovation are one of the most inventive areas of contemporary Irish design. Architects cut into old structures to admit light, set new materials against aged ones, and redesign buildings for contemporary lives and routines.

There is no shortage of ways to imagine what the world will look like after a climate catastrophe. Genres of movies and novels have been built around the question of what happens when contemporary safeguards fail, from dystopian fiction and post-apocalyptic literature to disaster films, graphic novels, and video games. Burning forests, submerged cities, abandoned infrastructure, resource scarcity, and mass displacement are a familiar visual and narrative vocabulary. We have become remarkably fluent in imagining the consequences of a world that fails to respond to climate change.

Botanical gardens bring the landscape, design, community, and scientific inquiry into close conversation. Emerging from medicinal gardens and private collections that were dedicated to classifying plants, botanical gardens were developed into institutions where specimens gathered across regions and climates could be cultivated and presented to public audiences. Their evolving position in society produced a distinct architectural repertoire, from greenhouses and conservatories to herbaria and laboratories and, eventually, visitor centers and hospitality spaces. Architecture remains integral to the botanical garden as an instrument of cultivation and a framework for organizing and studying the field of botany.

Public space is often intended to be perceived as universal, but access is unevenly experienced. For many women, moving through the city involves a continuous assessment of exposure, visibility, proximity to others, lighting, transport access, escape routes and the likelihood of harassment. These calculations are shaped by spatial conditions as much as social ones. Safety is a question of urban form, maintenance, mobility, governance and the distribution of public investment. While the built environment may not cause gender-based violence, it can intensify vulnerability and normalize unequal access, especially to public spaces.

For architects and planners, there is a critical distinction between designing for security and designing for safety. Security strategies tend to focus on surveillance, control, policing and the management of movement, while safety depends on whether people can see and be seen, if routes are legible, whether public spaces support activities throughout the day, and how long-term maintenance is supported. The role of design is to alter the conditions under which public life takes place.

San Francisco is a city that has always remade itself under pressure. Its Victorian streetscapes have survived seismic retrofits and glass towers, its neighborhoods defined as much by change as by its resistance to change. But no force in the city's history has reshaped the built environment as completely, or as quickly, as the technology economy. What began in the postwar sprawl of Silicon Valley migrated north and inscribed its logic onto the skyline and the lives of residents. The result of this logic is an architectural culture of considerable technical refinement and refined material palettes, yet one that remains largely indifferent to the existing population.

The cost of indifference is measurable and mounting. San Francisco must accommodate more than 82,000 additional housing units by 2031 under California's Regional Housing Needs Allocation framework, in a city where median rent already ranks among the highest of any American metropolitan area. Teachers, healthcare workers, and service employees are actively displaced by a real estate market calibrated to a single sector's income levels rather than the city's largest workforce.

The spatial consequences of urban form are revealed when health outcomes are mapped over neighborhoods. Neighborhoods that support walking, daily errands, social interaction, and access to essential services create opportunities to incorporate physical activity into routine tasks. Places that are organized around long distances and automobile travel suppress this opportunity. Physical activity and the motivation to incorporate it into daily life are shaped by the distance to a grocery store, the safety of a pedestrian crossing, the frequency of public transportation, the width of a sidewalk, and the quantity of services within walking distance.

Concéntrico returned to Logroño for its 12th edition in June 2026, transforming the city into a working site for architecture. Since its founding in 2015, the festival has built an identity on resisting a distant, controlled exhibition of design by constructing full-scale installations in the city's streets, plazas, and vacant lots. Concéntrico embeds installations directly into daily life, engaging residents and visitors as active, observant participants. This year's program brought together more than twenty projects by architects, designers, and researchers working across geographies and methods, each contributing to a citywide experiment in reimagining public space.

Nature-based solutions are a primary strategy for contemporary climate adaptation and urban ecological resilience, embraced by cities regardless of their geography or climate zone. Green roofs, urban forests, bioswales, expanding tree canopy, protected wetlands, and permeable landscapes are featured prominently in municipal adaptation plans. These interventions are deployed across neighborhoods, distributed through street networks, and measured by hectares restored, trees planted, stormwater retained, or temperatures reduced. This shift expands the role of ecology within cities, establishing environmental elements as infrastructure systems and providing planners with a grounded framework for integrating natural systems into urban development.

The Arts and Crafts movement is often remembered as an architectural style defined by handcrafted details, an intimate scale, natural materials, and a rejection of excess and industry. Its influence is frequently traced through visual characteristics that continue to appear in contemporary architecture and interiors, from exposed timber and crafted joinery to an emphasis on texture and permanence, yet reducing the movement to an aesthetic vocabulary overlooks its far more significant contribution. For William Morris, Philip Webb, John Ruskin, and their contemporaries, architecture was a question of how things were made, who made them, and whether the process of making could cultivate dignity, meaning, culture, and beauty.

The ice cream shop functions as an exercise in branding through playfulness in retail and commercial spaces, a small architectural gesture designed to draw people in off the street or across the park. From dense urban cores to quiet coastal towns, designers return again and again to color, materiality, and childlike curiosity as the primary tools for these spaces. This consistency appears to persist regardless of climate, culture, or context, signifying that the common threads of design are connected by experience and indulgence.

Agritourism is commonly understood as a hybrid model, with equal parts of overlap between the agriculture and hospitality industries. Under this framing, agritourism is valued as a variation on an existing theme, a supplementary activity layered onto rural production. This framing no longer holds in the 21st century as the scale and independence of agritourism's growth have transformed it into a distinct economic sector, one with architectural consequences that neither the agriculture nor the hospitality industries are equipped to address in isolation.

As cities around the world brace for extreme temperatures and waves of unrelenting heat, urban greening is one of the best solutions for leaders to combat this reality. The benefits of planting trees for physical health, mental well-being, and thermal relief are well documented, and a mature canopy can transform a space by several degrees on a hot day. Trees cool the air through evapotranspiration, filter pollutants and absorb stormwater, and enhance biodiversity in urban spaces.

Urban planning is often confused with adjacent disciplines: urban design, environmental policy, civic strategy, local politics, or data analytics. Moreover, the overlap in training and responsibilities between planning and urban practices makes the field difficult to define clearly. In practice, it is often easier to recognize the consequences of bad planning than to articulate the outcomes of good planning. When planning is working well for residents, it should disappear altogether. It should remove friction from daily life so that people would not think to credit a discipline at all. At its core, urban planning is the relationship people have with their environments, and when that relationship is functioning, the mechanics of housing, transportation, affordability, access, and inclusion should feel ordinary and expected.

This has not always been the lived experiences of planning practices, and in many places, it still is not. Urban planning has historically served as an instrument of division, used to segregate, exclude, and erase communities under the language of progress and order. Zoning maps, infrastructure investment, and land-use decisions are expressions of who holds power and that history is embedded in the boundaries that continue to organize cities around the world. It is embedded socially, as well as physically, in the assumption that participation in planning requires expertise or formal training that most residents lack.

Cities are increasingly designed to mitigate risk, and by doing so, need to collect data on climate, infrastructure, biodiversity, and social fragmentation so that the language of resilience becomes a fixture of planning. Yet the underlying conditions that produce polarization, civic disengagement, and ecological breakdown often remain unquestioned. The tools that dominate urban practice tend to address only one register of human experience, while the emotional and imaginative dimensions of transformation are not treated as reliable solutions.

Philosopher Felix Guattari proposed that sustained ecological transformation depends on simultaneous attention to three distinct ecologies: the ecology of the mind, the ecology of society, and the ecology of the environment. Mainstream environmental politics tends to concentrate on one or two of the three, flattening a complex condition into a defined problem with a clear answer. Ancient rituals remind us that transformation depends on practices that simultaneously engage the body, the community, and the environment.
