Architecture 101: The Essentials

Throughout the history of architecture, the circle has been associated with multiple meanings—from the cosmic geometry of ancient temples and the oculus of classical buildings to the rose windows of Gothic cathedrals and the portholes of ships. However, in the 20th century, the circle acquired a new cultural meaning. As aviation, space exploration, and technological innovation transformed the way society imagined the future, circular forms began to evoke machines, spacecraft, capsules, and even new forms of habitation.

Since the 2008 crash, a scatter of small practices (none more than fifteen years old and none large enough to need a manifesto in the traditional sense) have arrived, independently of one another, at some version of the same refusal: to sound too certain, too soon, in a discipline that had spent the previous decade selling confidence as a finish. They would probably resist being filed under one heading, but the coincidence itself is that something about practising architecture after 2008 made innocence look like the only posture worth trying.

The courtyard at Rozzol Melara measures two hundred meters on each side, which makes it larger than any square in Trieste. Two L-shaped blocks of exposed concrete enclose it, one of them twice the height of the other, climbing from seven to fifteen stories as the ridge falls away toward the gulf four kilometers below. Concrete pylons spaced every fifteen meters carry the blocks down to a slope they never quite touch, opening porticoes deep enough to walk through, and above them the facades resolve into loggias at the scale of a single room. Seen from the coastal road, none of that is legible; one can only see a gray line drawn across the hills.

The Pyramid of Tirana opened as a museum to Enver Hoxha in October 1988, three years after his death and three years before the regime collapsed. In the decades that followed, it served as a radio station, a conference venue, a nightclub, and a base for NATO during the Kosovo war. In 2023, MVRDV reopened it as a park and technology school, adding steps to the façades so that the building could be walked over. The inauguration was timed to the Western Balkans Summit on 16 October, a date that some critics pointed out was Hoxha's birthday. Two projects of national self-definition, thirty-five years apart and built on opposite political premises, have used the same structure.

In the heart of Ahmedabad's Navrangpura district in India sits the Sardar Vallabhbhai Patel Stadium. More than just a cricket ground, the stadium stands as one of India's earliest experiments in modernist public architecture. Built in the decades following the country's independence, the structure has not only become an engineering landmark, but also a major public space within Ahmedabad's urban fabric. Despite the building's architectural and historical significance, as well as its deep involvement in daily community life, it has suffered significant physical degradation as a result of decades of poor maintenance and lack of funding. That fragility is precisely why it has drawn international attention. In 2020, the World Monuments Fund (WMF) placed the Sardar Vallabhbhai Patel Stadium on its World Monuments Watch, a global list highlighting cultural heritage sites facing urgent preservation challenges. 

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.

As pillars of our cultural landscape, many masterpieces of the Modern Movement are often demolished, abandoned, or altered regardless of the context in which they are located. Preserving this architectural legacy highlights the role of architecture and design professionals in shaping built environments where continuity between the past and the present reinforces communities' sense of place. On Long Island, a coalition of advocates came together to save the A. Conger Goodyear House, which dates to 1938 and was designed by Edward Durell Stone. Considered one of the notable examples of the International Style in the United States, the house attracted significant attention throughout the 1940s, appearing in specialized journals, books, and popular publications.

In a slim volume with a yellow-edged cover, recently published by the Porto-based imprint Circo de Ideias, the architect Paulo Martins Barata (a founding partner of Promontório) makes a deceptively bold claim that the architecture produced in Europe since the Great Recession belongs to neither of the two camps that structured the twentieth century's fiercest disciplinary debate.

When we think of façades, we rarely think of them as habitats. We see them as the elements that separate interior from exterior, regulate temperature, reduce noise, and protect buildings from external conditions. They give architecture its visual language, but they are also expected to keep the outside world at a distance. In doing so, façades have often been understood as barriers: surfaces that define where human comfort begins and where the environment is meant to remain outside.

For much of the twentieth century, architectural culture was shaped by the pursuit of lightness. Steel structures and curtain walls reduced the building envelope to a thin layer separating interior from exterior, while façades became smooth, continuous surfaces where windows were cut as precise openings within an abstract plane. But for centuries, buildings were conceived as bodies of mass; walls possessed depth, windows were recessed within thick masonry, and space was often experienced as something carved from the solidity of construction. In recent years, several contemporary projects appear to revisit this older spatial logic, reintroducing thickness as an architectural condition through deep openings, monolithic volumes, and heavy envelopes.

Modern cities are running on performance indicators. They move millions of people each day, concentrate capital, separate land uses, and sustain complex systems of logistics and consumption. In that sense, the city functions as a system to be continually adjusted and optimized. 

Deep in western Honduras, within a valley near the Guatemalan border, lies the ancient Maya city of Copán. Flourishing during the Classic period between the fifth and ninth centuries CE, the city developed as a regional epicenter through trade networks, dynastic politics, and monumental architecture. Today, the site is designated a UNESCO World Heritage Site due to its extensive architectural remains, including stepped pyramids, sculpted stelae, and ceremonial core. Over a century of systematic archaeological research has documented its urban morphology, revealing distinct residential districts, civic spaces, and systems of movement and visibility.

Modern housing was one of the places where modernism made its boldest promise: that architecture could reshape not only the city, but the way people lived within it. As Argentine architectural historian Ramón Gutiérrez has argued, popular housing is "the great unresolved subject, one that usually does not appear in histories of architecture." In Latin America, this absence is significant. Across the 20th century, expanding cities turned housing into one of the clearest ways to imagine urban change, and modernism entered not only plans and drawings, but apartments, neighborhoods, streets, and domestic routines.

"There is no space without event, no architecture without action." When Bernard Tschumi wrote these words, he was articulating a fundamental principle of the architect's practice. Architecture is about behavior. Every stroke of a pen on a floor plan is a proposition about how occupants will move or what actions become possible.

Very close to the Mexican border, in the southwest corner of the United States, lies the city of San Diego. Its urban history began in 1769 with the arrival of a Spanish military expedition commanded by Gaspar de Portola, which marked the first permanent settlement in the territory that was known as Alta California. However, unlike the more formally urbanized administrative capitals and towns of Mexico and Central America, San Diego was conceived as a frontier outpost. Today, it has become the second-largest city in California, just after Los Angeles, and its urban grid tells a story about the Hispanic heritage that is intertwined with the contemporary cultural environment of the United States. 

When Mexico City hosted the Olympics in 1968, it was the first time the Games had been awarded to a Latin American country as well as the first time for a Spanish-speaking nation to host them. This made the games a good opportunity to project Mexico and its culture internationally, thus prompting the government to constitute an organizing committee with prominent local talent. They appointed Pedro Ramírez Vázquez as its president, a Mexican architect who held significant influence over the state's mid-century building program. His approach was explicit: architecture as a synthesis of international modernist technique with Pre-Columbian references and local material culture. Under his direction, the committee would oversee the construction and adaptation of venues distributed across the southern districts of Mexico City, nearly all designed and built by local architects, engineers, and technicians. 

The relationship between constraint and design excellence is well established in architectural theory, yet often remains underexplored in discussions of site-specific practices. When architects encounter extreme topography, they face a fundamental choice: transform the landscape to accommodate the building, or modify the building to fit the landscape. The first approach is straightforward and requires the builder to cut, fill, terrace, and build on level ground. This choice, however, carries cascading consequences as any amount of earth moved may destabilize slopes, disrupt drainage, and fracture ecosystems. A growing body of innovative architectural work demonstrates an alternative to earth-moving and retaining walls.

Architecture is traditionally chronicled through the persistence of the solid. We define the discipline by the weight of the lintel, the mass of the pier, and the resistance of the wall. Even when lightness is invoked, it is usually understood as a subtractive act, the thinning of a section or the precarious reduction of a load. Yet there is a parallel history, less visible and harder to isolate, in which the primary material of construction is not what occupies space, but what moves through it.
