Seeking to create a fluid dialogue between architecture and its surrounding landscape, the study of topography embodies an awareness and exploration of the use of materials, self-sufficient strategies, low-maintenance solutions, and landscape designs that integrate into the natural environment and minimize the environmental impact of projects. Beyond recording variations in elevation, sun orientation, prevailing winds, or drainage slopes of the terrain, several architects in Argentina demonstrate a strong interest in developing architectural solutions capable of adapting to natural geographies and restoring the bond between nature and the human being.

In the history of modern architecture, Louis I. Kahn is regarded as the undisputed master of monumentality in the United States. At the height of his career, Kahn managed to create a unique type of architecture, often awe-inspiring, but avoiding overdone grandiosity, expressing its constructive system, yet avoiding structural exhibitionism, steeped in history but developed with a new language and system of forms. His interest in light as a functional element and the specific qualities of materials extended beyond his buildings, in all the objects he created to populate them following their intrinsic spirit. To celebrate this legacy, Form Portfolios has now launched "Monumental Modernism," the first collection of lighting, objects, and furniture modeled after those discovered in Louis I. Kahn's buildings.
For over five decades, Swiss photographer Thomas Mayer has developed a serene, emotional, and documentary language for architecture. His lens captures the random and memorable moments of our built environment - reflections in the rain, long blue hours in Nordic summers, and the quiet darkness of sacred spaces. Recognized by ArchDaily as one of the top architectural photographers, Mayer carries an abundant fascination for light and space.
Tucked discreetly beneath the colonnade of Saint Mark's Square in Venice, Carlo Scarpa's Olivetti Showroom exerts a quiet yet unmistakable presence. Though often overshadowed by the grandeur of nearby landmarks—St. Mark's Basilica, the Clocktower, the Loggetta, and the Procuratie Vecchie—it attracts a particular kind of visitor: those who seek out one of Scarpa's architectural gems hidden in plain sight. Modest in scale but rich in detail, the showroom is meticulously maintained by FAI (Fondo Ambiente Italiano), the National Trust for Italy.

Gallaudet University was established in 1864, becoming the first American educational institution for the deaf and hard of hearing. The university is officially bilingual, with American Sign Language (ASL) and written English used throughout the educational programs. Over the years, the university has grown, adapting both its teaching methods and its spaces to the needs of its students, in turn learning from them how to counter the challenges they face and create a safer and more comfortable environment. These lessons turned into design guidelines, created to educate the architectural community about the strategies they can employ to create more accessible spaces for all.
As a result of the ideas competition organized by the governments of Sweden, Finland, and Norway in 1958, Sverre Fehn's Nordic Pavilion won first prize, becoming one of the most significant works of his career and one of the most outstanding Scandinavian architectural achievements during the mid-20th century. Designed to create a space at the Venice Biennale for the biennial exhibitions of these countries, Fehn's proposal addressed several key architectural challenges—ranging from its integration with the site and incorporation of pre-existing elements to the handling of physical boundaries and uniform natural lighting. His design explored the interaction between architecture and trees, the flexibility in the exhibition space, the filtering of light, the connection between interior and exterior, the concept of movement through space, and the display of artworks.
Architecture is often defined by its physical form, materials, and structural elements, but light and shadow truly shape the experience of space. These elements influence perception, guide movement, and evoke emotional responses, transforming static structures into dynamic environments. Throughout history, architects have harnessed the interplay of light and shadow, using it as a fundamental design tool to create atmosphere and meaning.
The creative fusion of art and activism in urban spaces has propelled the British collective Led by Donkeys into the spotlight, garnering millions of views for their interventions on social media. Their critical visual occupations - whether billboard messages during the day or large-scale projections at night - raise a compelling question: which medium holds the greater persuasive power? The book "Led by Donkeys: Adventures in Art, Activism and Accountability" offers a deep dive into their conceptual approach, charting their rapid evolution over six years. What began as a London-based response to Brexit has expanded into a global critique of political hypocrisy, addressing issues in Europe, the Middle East, and America. For Peter Weibel, former director of the ZKM Center for Art and Media in Karlsruhe, Germany, the innovative fusion of activism and art—or "Artivism"—represents the first new art form of the 21st century. Years of experience in environmental activism provided the group with crucial insights into the mechanics of political communication, the organization of public interventions, and the challenges of achieving meaningful societal change.
As communities grow more multicultural and increasingly diverse, these spaces serve as physical manifestations of religious inclusion, encouraging the acceptance of religious and ethnic minorities within multicultural landscapes. Their proliferation reflects a growing need for inclusive environments that cater to diverse spiritual needs while promoting interfaith understanding. However, designing and implementing these spaces presents complex challenges, often sparking debates about representation, neutrality, and the very nature of sacred space. These discussions underscore the delicate balance architects must strike in creating spaces that are both universally welcoming and spiritually meaningful.

In architecture, it's often the finer details that make the grandest impact. Across the ages, architects have carefully oriented buildings to balance function and aesthetics, with light as their guiding principle. The pursuit of perfect lighting in buildings dates back to medieval times—and the search continues. It turns out that simply allowing light into a space isn't enough; it's the direction and quality of that light that truly elevates the environment.
This year, the VELUX Nordic Architecture Competition—aptly titled "Daylight from Above"—invited architects from Denmark, Sweden, and Norway to explore the nuances of natural light in residential design. The competition urged them to craft spaces where light plays a starring role, sculpting interiors that shift and change with the hours and seasons. The aim? To create homes where light doesn't just brighten a space but elevates the experience of living in it..
Robert Wilson embodies the roles of director, set designer, scenographer, lighting designer, and architect in a single figure. Internationally celebrated as a pioneer of stage lighting and honored with numerous prestigious awards, including the Golden Lion of the Venice Biennale and the Praemium Imperiale, Wilson, now in his eighties, continues to travel the world, staging remarkable productions. His use of light and color is marked by precision and minimalism, creating scenes that skillfully oscillate between stillness and drama. During rehearsals at the Düsseldorf Schauspielhaus, he elaborates on the interplay between stage and architecture, his creative process, and the profound impact of light on darkness.
Walls have long been more than mere structural elements; they are canvases that narrate stories, reflecting desires for nature, spirituality, or the pursuit of tranquility and stimulation. With advancements in addressable LED pixels, walls have evolved into immersive digital surfaces capable of displaying any image in large format, adapting to the needs of the moment.
However, while universities continue to train architects and interior designers to create static buildings, the art of meaningful storytelling through digital screens—especially those with dynamics—remains largely unexplored in academic curricula.
Over the years, the nocturnal landscape of cities has witnessed a significant transformation, marked by the emergence of more than 80-night mayors globally, a trend that has been on the rise since the early 2000s. Andreina Seijas, currently working as an Associate at Gehl, has analyzed these shifting dynamics of night-time governance in her research and during her doctoral studies at Harvard GSD. Seijas speaks in the interview about this development, challenges, and opportunities with night mayors, global differences, and the role of climate change. Seijas' upbringing in Caracas, Venezuela, where safety concerns dictated strict curfews, ignited her passion for creating safer, more inclusive urban environments, particularly for the youth. Her quest for a better future for the urban night explores the potential for cities to become safer, more inclusive, and more productive by creating spaces for work and leisure after dark.
Although an architectural project comes to life with palpable materials, it is also defined by intangible qualities that give it richness, dynamism, and liveliness. Among them, the interplay of light and shadow can transform environments and affect their perception, determining the user's spatial experience. Besides providing natural ventilation, privacy, and thermal comfort, lattices allow this duality by filtering the entry of sunlight while projecting repetitive figures on the surface. In this way, perforated walls and ceilings can create multiple geometric patterns of light and shadow that become design elements capable of generating unique atmospheres.
A recent study suggests that our home galaxy, the Milky Way, cannot be seen by one-third of humanity. Why? Millions of city lamps brighten our cities every night, but only part of their light is used to actually illuminate streets or sidewalks – the rest is lost and emitted above the horizon, brightening the night sky and contributing to what is known as light pollution. However, as the artificial glow from towns and cities increases every year, the consequences of this urban phenomenon go beyond just preventing us from seeing stars. Other harmful effects include: causing a hazardous glare that can reduce safety, excessive energy consumption, waste of money and resources, disruption of ecosystems’ natural day and night cycles, suppression of melatonin production and several negative repercussions on public health. In this sense, choosing the right lamps (with a well thought-out design) is crucial to reduce light pollution.
