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.

The International Union of Architects designates the first Monday of October as World Architecture Day each year, aligning it with the United Nations' World Habitat Day. This year, both occasions are drawing attention to the global housing crisis as a fundamental element of human dignity, inclusion, and well-being. The UIA's motto reads: "Housing is a Human Right. Build It." The organization calls on architects to contribute to advancing equitable access to housing through design, research, and advocacy. From a holistic perspective, the crisis consists not only of a shortage of residential buildings, but of multiple, interconnected barriers to accessing an adequate place to live. The challenge calls on the dual nature of the architect's work: the capacity for abstract design thinking, and the practical knowledge to transform material reality. For architecture to make the right to housing a reality, both capacities must be put into practice: building new governance structures, different models of shared ownership, designs for alternative forms of cohabitation, and new, environmentally sustainable construction systems.

"After all, time is a key ingredient of my profession," states Francis Kéré in his book Francis Kéré: Building Stories. Architecture is constantly evolving and transforming over time. Bricks, doors, windows, walls, stairs, and other elements become the protagonists of a process that begins with a sketch and eventually takes shape as a built work.

Considering that architecture begins when its inhabitants start to make a space their own, Francis Kéré develops his projects progressively, continuing to work on the design even during the construction phase. As his architecture grows over time, integrates with its surroundings, adapts to the needs of its users, and responds to change in flexible and experimental ways, it seeks to become part of the lives of those who inhabit it.

The Lucas Museum of Narrative Art officially opens its doors to the public today, September 22, 2026. The museum's sculptural, curved silhouette was designed by Ma Yansong of MAD Architects, with landscape architecture by Mia Lehrer of Studio-MLA and Stantec serving as executive architect. The opening follows a Founding Members Preview held from September 5 to 11, giving members an exclusive early look at the galleries, and a star-studded opening night on Saturday, September 19, featuring celebrity co-chairs at a launch event for the museum, co-founded by George Lucas and Mellody Hobson. The date aligns with the announcement made by the institution nearly a year ago, though the project has a longer history: approved in 2017, with construction beginning the following year, the opening was originally planned for 2025. The museum sits within an 11-acre (4.5-hectare) site in Los Angeles's Exposition Park and comprises a 300,000-square-foot (27,900-square-meter) structure featuring galleries, two theaters, a retail store, a library, a café, a restaurant, and event spaces.

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.

On the International Day of Democracy, this year the United Nations revisits a traditional idea within the concept: broad citizen participation in government decision-making. On this occasion, the international body invites reflection on how participation and the inclusion of diverse voices in government decision-making can help build a more equitable society. From a spatial perspective, reflection on democracy can move beyond this vertical framing and instead understand it through encounter. What does it mean for a space to be democratic? How can architecture contribute to achieving the principles historically associated with democracy? In the current context of crisis in political organization systems worldwide, this day serves as a platform to question individualization and authoritarianism through the socio-spatial tools available to us.

Launched in September 2024, the Rediscovering Modernism in Africa series joined a growing worldwide interest in this topic. Previously underrepresented in architectural discussions, the work of architects and researchers on the continent and abroad has continued to tell the story of these high-quality modern works of architecture. These buildings represent designers striving to create locally suited architecture using global concepts and technologies, coinciding with huge political changes as most African countries gained their independence.

Oslo is the capital of Norway as well as its largest city, serving as the country's political, economic, and cultural center. Nestled at the head of the Oslofjord and surrounded by forested hills, it's home to roughly 700,000 people in the city, with over a million living in the greater metropolitan area. Founded around a thousand years ago, Oslo has a long history as a trading post and administrative seat. However, much of its modern character was shaped after a major fire in the seventeenth century led to a full rebuilding under Danish rule, when it was briefly renamed Christiania. Today it consistently ranks among the world's most livable cities, prized for its blend of urban life and easy access to nature.

Nairobi's architectural identity was transformed by Kenya's independence in 1963. As the new nation sought to define itself, the city became a testing ground for a modern architecture that could embody progress while responding to African culture, climate, and local conditions. This opened a period of architectural experimentation, with different approaches emerging to the relationship between modernity, identity, and place.

The Kenyatta International Convention Centre is perhaps the clearest expression of this moment. Its architecture brought together modernist principles with references to African forms, establishing a distinctive response to the ambitions of a newly independent nation. Around it, Kenyan and international architects developed other interpretations of modernism, from the sun-shading facades of Reinsurance Plaza to the sculptural silhouette of Nation Centre, alongside religious, educational, and civic projects that expanded the architectural vocabulary of the city.

An exhibition tracing the vision behind Herzog & de Meuron's ten selected projects in China will open on September 12, 2026, at the M+ Museum in Hong Kong. The exhibition marks the museum's fifth anniversary; since opening, M+ has built its collection around visual art, design and architecture, moving image, and Hong Kong visual culture from the twentieth and twenty-first centuries. The museum building, designed by Herzog & de Meuron between 2012 and 2021, is located in the city's West Kowloon Cultural District (WestK), a cultural hub spanning forty hectares alongside Victoria Harbour. "Herzog & de Meuron: In Focus" is curated by Ikko Yokoyama and Iris Ng and reviews projects dating from 2002 to 2021, including Tai Kwun in Hong Kong (2006–2018) and the National Stadium in Beijing (2002–2008).

ZHA has been selected to design a new 198-hectare urban district in Baku, Azerbaijan. The project surrounds the existing Baku Expo Center events venue in a pine forest area that is planned to be preserved. The plan responds to the city's population growth over the past decade with a masterplan to organize the provision of a wide variety of residences. This is the firm's second project in Baku, after the Heydar Aliyev Center cultural venue, completed in 2013. On a different scale, the buildings in the new district appear to follow the geometric style inherited from Zaha Hadid, in a series of white buildings with rounded edges that convey an idea of fluid architecture.

In 2021, a collaboration between the Italian architecture studio Mario Cucinella Architects and WASP, an Italian 3D-printing company, led to the development of TECLA: a house 3D-printed entirely from raw earth. Five years later, the technology behind it has grown, quietly spreading across several continents and design practices. By controlling the speed, angle, and path of the extruder nozzle, architects are able to create more than just walls. Throughout the years, they have been experimenting with how to shape the 3D-printed material into detailed surface motifs, reintroducing relief, texture, and intricate patterns directly into the structure. In this way, they are attempting to bridge earth-building traditions with digital computation, in an era where code is starting to influence form and material expression in architecture.
