Coastal development in major cities has long been a terrain of opportunity and contention—shaped at once by the pursuit of capital (premium views, scarce land, and the promise of reclamation), by civic demands for public access and collective waterfront life, and by contemporary aspirations for sustainability and place-defining urban identity. Precisely because these agendas rarely align, extracting the full potential of waterfront sites is never straightforward.
Yet in New York City and Hong Kong, we can trace each city's ambitions—despite differing strategies, priorities, and political logics—through a set of keystone projects that anchor their coastlines. Read together, these projects reveal not only what each city chooses to value, but also what it is willing to trade off in order to build at the edge.
Across cities worldwide, architecture unfolds continuously at the scale of people and community—not only through new buildings, renovations, or monumental works. "Third spaces" are especially revealing. Consider the street-side culinary realm: how seating, serving, and lingering occupy the edge of the street often discloses a city's cultural codes and spatial habits. What forms of dining and inhabitation have emerged in response to local climate, regulation, and social custom—and how have they evolved over time?
In parts of Europe, for instance, al fresco in Italy and en terrasse in France name culturally specific ways of dining in public, drawing the meal into the urban field—attuned to weather, air, and the passive sociability of people-watching. Since COVID-19, New York City has similarly expanded outdoor dining, reflecting a community-driven desire to engage the streetscape while eating—an everyday, street-level "third place" within a dense metropolis.
CityMakers, The Global Community of Architects Who Learn from Exemplary Cities and Their Makers, is working with ArchDaily to publish a series of articles about Barcelona, Medellin, and Rotterdam. The authors are the architects, urban planners, and/or strategists of the projects that have transformed these three cities, which are visited in the "Schools of Cities" and studied in the "Documentary-Courses" made by CityMakers. On this occasion, Alejandro Restrepo Montoya, Director of Urban Planning and Architecture of Medellín, presents his article "Environmental Urbanism and Urban Geographies, Medellín 2024-2027"
Medellín's urban plan focuses on answering how urban planning can improve people's quality of life. By developing its proposal, the city is promoting the social benefits that these urban planning practices can generate. Medellín emphasizes the use of natural and environmental conditions, such as valleys, streams, rivers, mountains, and hills, to develop urban planning criteria that address social needs.
Informal architecture is the dominant mode of urbanization in rapidly growing and industrializing cities worldwide. In Delhi, the city with the largest population in India has half of its residents living in informal settlements. Lagos, with a population of over 22 million, also has 60% of its residents living in informal settlements. This pattern is also observed in Cairo, Johannesburg, Kinshasa, and other cities in the global south that face similar challenges of inequality and housing shortages. As their population grows and urbanization progresses, the exploration of informal architecture schemes to address the demand for affordable housing and basic services will only increase. While the primary purpose of design is to provide structure, lessons from informal architecture offer insights into how architects can respond to such schemes.
One of the most radical instances of public space transformation happened recently. During the early months of the Covid-19 pandemic, public space transformed into “a medical resource, a distribution hub, an overflow space, a center of protest and resistance, a gym, a senior center, a community center, a daycare center, a schoolyard, a night club, a transportation corridor, an outdoor restaurant, a shopping mall, a children’s playground, an outdoor theater, a music venue, a nature center, and a place of belonging and ‘being at home.’”

Despite the bad reputation of public housing in the United States, organizations, planners, and architects in Portland, Oregon are determined to create affordable housing that does not sacrifice quality or aesthetic appeal. While Portland has developed a bad reputation regarding its homelessness problem, in the past four years resources have flowed in the right direction, and designers have taken this in stride to design livable and striking buildings, within very restrictive budgets. Through innovative and creative approaches to construction and design, these organizations and designers have utilized federal, state, and city resources to make these types of projects a reality.
February 20th marks a new edition of the World Day of Social Justice. The theme, "Overcoming barriers and unlocking opportunities", is a perfect occasion to reflect on the importance of equity in all areas of society - and especially from architecture and urbanism. And yes: they both have a fundamental role in building accessible cities and are important tools for addressing the challenges of economic inequality and social exclusion.
What is the 15-Minute City? It’s every city ever built by humans on this planet until a century ago, but with a catchy new name. If a city’s old parts haven’t been destroyed in the past century, it’s the areas that attract the most tourists. And people will travel across continents and oceans to experience the best of them.
Forty years ago, a few pioneers decided to start building 15-Minute Cities again. Actually, they built 5-minute cities because they didn’t think people would walk for 15 minutes—and, in the early 1980s, they were right, because people were so conditioned to driving everywhere back then. Seaside, Florida, is where it all began. Time magazine called it “the little town that changed the world.” For the first time in the modern history of sprawl, people could toss their car keys in a drawer or hang them on the wall and leave them there for days. When people returned from Seaside vacations, they came back asking, “Why can’t we build this way at home?” And soon, the New Urbanism was born.
On first impression, Quarticciolo is a handsome district in Rome. A human-scaled public housing complex comprising red and yellow midrise buildings arranged around internal courtyards and gardens. Designed by architect Roberto Nicolini during the Fascist regime, this village feel isn’t found in the massive postwar residential schemes elsewhere in the capital. Like other rationalist architects, Nicolini was inspired by the ancient city. Basing the layout on a classical orthogonal grid pattern, he allowed just one tall structure, the Casa del Fascio (the Fascist party headquarters), a fortress tower that looms over the main square. Most of the buildings were constructed between 1938 and 1943 to house a working-class population that was forcibly moved from Rome’s historic center to the outskirts to make way for Mussolini’s grand public works.

The fourth edition of the Timișoara Architecture Biennial, or Beta, is focusing on the theme of “the City as Common Good”. Through a wide range of events, Beta aims to address topics that are relevant and urgent globally and explore their impact on the local built environment and its response to the needs of the communities. Taking place at various locations in the city of Timișoara, Romania, this year’s festival begins on September 23rd and ends one month later, on October 23rd.
Built environments are a reflection of the social order and dynamic ideals of society. Neighborhoods and cities are cultural relics shaped by diverse communities, some of whose voices are heard louder than others. In the past few decades, Indian metropolitans have been booming with urbanization. Holding cities back from being Utopian hubs of growth is spatial inequality. The residential segregation that patterns the cities of India can be understood through the caste system. The issue, however, is largely intersectional. Forces rooted in class, religion, and gender also structure the country's social landscape.
The concept of equity is different from equality; equity means everyone needs support, but not necessarily in the same way. Therefore, the concept of urban equity allows us to preserve the uniqueness of each region of a municipality, protecting diversity and richness without overlooking infrastructure needs, which directly affect the quality of public space and the basic services required for a private residence - it allows us to design and invest in the city fairly, regardless of the region.

Throughout the world's cities, in the midst of current and projected crises-- environmental, health, economic, and otherwise--one question looms: How can we prepare our urban centers' most vulnerable sectors?
Current data paints a bleak picture of cities and the impact of climate change. With urban populations skyrocketing as people around the globe seek opportunities for a better life in the world's urban centers, cities have become gluttons for energy and other resources while simultaneously producing more emissions than ever before. On top of this, 3 out of 5 cities are at high risk for natural disasters.

Social Urbanism: Reframing Spatial Design – Discourses from Latin America, a new book by Maria Bellalta, ASLA, dean of the School of Landscape Architecture at the Boston Architectural College, is a welcome addition to the growing number of publications on the social justice-oriented form of urbanism, architecture, and public space emanating from Medellín and Colombia. The achievements of social urbanism have rightfully become synonymous with Medellín in the world of landscape architecture, urban planning and design, and architecture.
