Set on the edge of the Mediterranean and shaped by centuries of continuous occupation, Naples is a city where architecture is inseparable from time. Layers of Greek foundations, Roman infrastructures, medieval churches, Baroque palaces, and Modern interventions coexist within a dense and compact urban fabric. Naples reveals itself as an accumulation of structures, adaptations, and reuse, where buildings are rarely isolated objects and more often part of a larger spatial, social, and historical system.

Perched above the cliffs of Crimea, the Druzhba Thermal Sanatorium appears less as a building than as a landed spacecraft. Its circular forms, suspended decks, and spiraling ramps evoke a scene from Andrei Tarkovsky’s Solaris (1972), where architecture and psychology merge into a single landscape. Built between 1978 and 1985 by Igor Vasilevsky, the complex was conceived as a thermal resort for workers of the oil industry, part of the Soviet Union’s extensive network of sanatoria dedicated to health and recreation.

Architectural heritage is often described as what survives time. Yet survival does not explain why certain buildings are preserved while others disappear. Many works now protected as cultural heritage were once criticized, contested, or openly rejected; they were accused of being socially misguided, materially flawed, or symbolically excessive. Over time, however, these same shortcomings have become central to their meaning as heritage emerges as a slow and unstable process of interpretation.

A long table can sit almost anywhere and still do the same work. It can stretch beneath a market canopy, run along a school dining hall, or occupy the center of a shared living room, and it immediately changes the room’s temperature.

Once a Najdi settlement defined by mudbrick walls and courtyard houses, Riyadh has undergone one of the most radical urban transformations of the 20th and 21st centuries. The discovery of oil reserves, the consolidation of political power, and the rapid expansion of infrastructure reshaped the city from a regional capital into a sprawling metropolis almost within a single generation. As a result, Riyadh’s urban fabric is marked by discontinuities, fragments of vernacular architecture coexist with mid-century institutional modernism, and a rapidly evolving contemporary skyline.

Beneath the visible surface of cities lies an invisible architecture. Subways, tunnels, water systems, data cables, and bunkers form a dense network that sustains urban life while remaining largely unseen. The ground beneath our feet is not a void but a complex territory that holds the infrastructures, memories, and anxieties of our age. In recent years, as land becomes scarce and climate pressures intensify, architects and urbanists have turned their gaze downward, rediscovering the subterranean as both a physical and conceptual frontier. To design underground is to engage with the unseen mechanisms that shape the world above.

On the southern edge of Vienna, a cluster of monumental terraces rises above the cityscape, their stepped balconies cascading with greenery and their rooftops crowned with swimming pools. This is the Wohnpark Alterlaa, one of the most ambitious social housing projects in postwar Europe. Designed by Austrian architect Harry Glück and built between 1973 and 1985, the complex was founded on a provocative principle: municipal housing should not only provide affordable shelter but also offer the pleasures and amenities usually reserved for the wealthy.

In architecture, most practices revolve around delivering projects to clients. Offices are shaped by deadlines, budgets, and clear briefs. While this structure produces buildings, it rarely leaves space for architects to question broader issues — about how we live, how cities are changing, or what the future demands of design. But alongside this production-focused system, a quieter movement has emerged: studios, collectives, and foundations that prioritize research, experimentation, and reflection. These are the architecture think tanks — spaces designed not to build immediately, but to think first.

In contemporary architecture, commercial spaces have become more than points of sale; they are stages where identity, image, and experience converge. Stores, showrooms, and branded interiors often operate as laboratories where architects experiment with form, material, and light, translating corporate narratives into spatial experiences. In this context, the architect emerges as a mediator of desire, shaping atmospheres that guide perception, evoke emotion, and subtly influence behavior. This role reveals a complex intersection between design and capitalism: the creation of spaces that sell not only products, but also aspirations, lifestyles, and cultural meaning. By transforming commerce into an architectural performance, these projects invite reflection on how the discipline negotiates its agency in a world where visibility and image have become as essential as function.
