With the Milano–Cortina 2026 Winter Olympics underway, it is worth looking back at how the Olympic Village has evolved from a purely functional solution into a strategic urban project. From improvised housing compounds to key pieces of urban regeneration, Olympic Villages have repeatedly functioned as large-scale experiments in how parts of the city can be built within a short period of time.

Designed under intense time pressure and for a highly specific population, these environments reveal shifting ideas about housing, collective life, and the urban legacy of mega-events. Across different editions, the Olympic Village reflects broader ways in which events, housing, and cities intersect under conditions of urgency.

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.

With more than 3,000 apartments housing nearly 9,000 residents, Alterlaa was conceived as a city within the city. Alongside its residential towers, it incorporates shops, schools, medical services, and cultural facilities, ensuring that daily life can unfold entirely within its boundaries. The project reflects a moment of optimism in Vienna's urban policy, when housing was understood as infrastructure for collective well-being rather than as a commodity.

Historically, architecture and the built environment have insisted on creating flat, hard surfaces. In earlier eras, walking without paved ground meant mud-caked shoes, uneven footing, tripping hazards, standing water after rain, and high maintenance. Hence, as we shaped cities, we prioritized a smooth, continuous, solid horizontal datum. The benefits are real: easier walking, simpler cleaning, and straightforward programming—furniture, equipment, and partitions all prefer a level base. This universal preference for building on flat ground remains the norm and, for many practical reasons, will likely continue to be.

What's less recognized is that making a truly flat surface is surprisingly difficult—and many well-executed "flat" floors aren't perfectly flat at all. They are often gently sloped, calibrated to precise gradients for drainage. While interior spaces do not always require this, many ground floors and wet areas do incorporate subtle inclines as a safeguard—whether for minor flooding or to manage water that overflows from the street or plumbing when one of the discharge systems is malfunctioning.

Following California's Covid-19 health regulations in early 2020, Metro, the Los Angeles public transit agency stopped collecting fares on its busses as a safety precaution measure. However, the company's decision turned into the United States' biggest free-transit experiment, as ridership never dipped below 50 percent, even with the stay-at-home orders enforced by the government. Following 22 months of the decision and around 281 million fare-free transits, the company has decided to restart collecting fares, but is planning on using the information gathered throughout these two years to implement future improvements and introduce other free or reduced-fare programs in the city.

In this week's reprint, author Walter Jaegerhaus explores the U.S. housing challenge, drawing a timeline of the evolution of different architectural solutions, from around the world. Seeking to "inspire designers today to create new housing options", and hoping "that the U.S can again embrace its experimental origins and try out new ideas and methods", the article highlights examples from Europe and the Americas.

Around the world, cities are the “ground zero” of inequality and unsustainability. The two largest cities in the United States, New York City and Los Angeles, are also the two most unequal cities, and one-third of the United Kingdom’s poorest 10% of families live in London. Meanwhile, two-thirds of the world’s energy and 70% of global carbon emissions are attributed to cities. This leads to the question of how the evolution of public policy, and urban design, can strategically combat these two growing issues. Around the world, cities are looking to mobility as part of the solution, and in particular, asking a simple question: what if public transport was free?

In some theoretical books, architecture and the human body are more or less the same, each depending on one another. Oftentimes, however, it is the body that undergoes detrimental adjustments to adapt to the architecture, not the other way around. 

In the newly released book X-Ray Architecture, architectural historian Beatriz Colomina argues that health facilities inspired modern architecture's most dominant formal signatures. 

Every famed design movement has an interesting story of how it managed to influence architecture and design through the years. Despite their impact, not all movements began with the same principles they managed to ultimately lead with, and Bauhaus is no exception. The clean-cut modernist archetype, which has pioneered modern architecture for a century now, was once an experimental design institution of expressionism, unbound creativity, and handcraft, bridging the styles of Art Nouveau and Arts and Crafts with Modernist designs.

Studio Gang, BIG, Calatrava and SOM are among twelve leading architecture teams vying to work on the Chicago O'Hare International Airport expansion. The city’s request for qualifications calls for demolishing O'Hare's Terminal 2 to replace it with a global concourse and terminal for both domestic and international flights from United and American Airlines. The city’s Department of Procurement Services estimates the total costs of the expansion process (from design through construction) will cost an approximate $8.7 billion. Known as O’Hare 21, the project represents O’Hare’s first major overhaul in 25 years.
