Infrastructures: The Latest Architecture and News

Air rights transactions have become essential in urban development, allowing cities to grow vertically while preserving limited land resources. Typically defined as the right to use or sell the space above a property, air rights enable property owners to transfer unused floor area ratio (FAR) to neighboring parcels, creating increased density and financial gain opportunities. As urban centers face mounting pressures from limited land supply and population growth, air rights continue to offer a creative solution that fosters architectural innovation and economic efficiency.

NEOM has announced the appointment of new partners to advance the city planning, design, and engineering for the initial phase of THE LINE, a core component of its region in northwest Saudi Arabia. The collaboration brings together Delugan Meissl Associate Architects (DMAA), Gensler, and Mott MacDonald, who will work alongside THE LINE's design and development teams to shape the urban landscape, offering expertise in urban design, planning consultancy, and infrastructure development.

New York-based office Field Operations, renowned for their work on Seattle's waterfront and New York's High Line, along with Toronto's Brook McIlroy, have been tasked with transforming underutilized lands beneath the Gardiner Expressway in Toronto. The project was launched by The Bentway Conservancy, in partnership with the City of Toronto, and represents the second phase of the development aiming to revitalize underutilized spaces along the expressway. The initiative set out to transform three large traffic islands between Dan Leckie Way and Spadina Avenue into an 11,500-square-meter public space for recreation and community activities.

Traveling on land through vast regional areas of African countries has been an inefficient ordeal, particularly in West Africa. Google Maps optimistically estimates it would take 53 hours to drive nonstop from Lagos, Nigeria's largest city, to Dakar, Senegal's capital. However, this estimate doesn't account for the poor road infrastructure, complex border crossings, and socio-economic challenges that realistically extend the journey to about a week.

This is why the ongoing Trans-West African Coastal Highway project offers a great opportunity to connect and unlock the region's potential. This project, also known as TAH 7, is a transnational highway initiative linking 12 West African coastal nations, from Mauritania in the northwest to Nigeria in the east. Its gradual construction opens new avenues for freight movement, rail infrastructure, and, more importantly, innovative forms of architecture around borders, addressing their unique socio-cultural functions.

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.

The relentless drumbeat of climate disasters in the headlines—scorching heat waves, raging wildfires, historic floods, crippling droughts—are no longer a series of anomalies. As a grim new reality across much of the globe, these extreme weather events, driven by human-induced climate change, are becoming more frequent and severe. In short, they are clearly symptomatic of a broader and more pervasive environmental crisis.

Eastern and Southern Europe is enduring a severe heatwave, with temperatures reaching over 40 degrees Celsius in many countries including Greece, Croatia, Macedonia, and Romania. Driven by hot air from North Africa, this prolonged heatwave has raised significant threats for residents and has strained the cities’ mechanisms for protection and climate mitigation. As the heatwaves expose the vulnerabilities of urban infrastructures, cities across Europe are striving to implement measures to address these challenges.

Following the collapse of the Francis Scott Key Bridge in Baltimore, Maryland, construction group WeBuild, in collaboration with design office CRA-Carlo Ratti Associati and engineer Michel Virlogeux, has revealed an updated design for a replacement bridge. The new cable-stayed design aims to redefine the entrance to the Baltimore Harbor and offer an improved version of this symbol of the city.

MASSLAB has just won the competition for the new roof of Bragança's Water Treatment Plant in Portugal. Integrating public use of this infrastructure, which until now only serves a functional purpose, the project showcases adding value to existing infrastructure by rethinking them. Blending architecture, landscaping, and urban design to transform this structure into a vibrant public space, MASSLAB seeks to change the perception of water treatment facilities in urban settings. By reimagining the roof as a livable infrastructure, the project transforms the purely functional roof into an engaging and integral part of the urban fabric.

Social infrastructure encompasses the resources and services that allow the creation of communal bonds and social connections. Within the built environment, it manifests through public spaces like parks, libraries, and community centers alongside threshold spaces such as public transportation stops.

These public social spaces play a crucial role in strengthening communities and, in turn, their ability to respond to catastrophic climate-related events. They can provide physical shelter to the populations most vulnerable to these events and foster resilient networks of people who can more quickly recover. Given the escalating frequency of extreme weather events in the United States due to climate change and its social infrastructure inadequacies, examining public spaces as a critical tool for climate resilience becomes vital.

I am by no means an expert on public-private partnerships. But for about 10 years, as the University of California Berkeley’s campus planner and then campus architect, I watched these developments play out in higher education—sometimes from a front-row seat, sometimes as a participant. During that time, this strategy, promoted with great enthusiasm and optimism, was touted as the answer to whatever problem arose. And yet the definition of a public-private partnership was slippery. The concept itself seemed to be all things for all people, depending on what was needed, who was recommending it, and what equivalents (if any) existed outside the university. The bandwagon continues to play today, making it ever more important to nail down the pros and cons of this development strategy, not only for colleges and universities, but for all public decision-making.

Medellín stands as an inspiring example for many cities worldwide. It is a city that transitioned from deep collective fear to hopeful enthusiasm for urban and social life characterized by quality and coexistence. The city's crisis has always been associated with violence and drug trafficking. However, this crisis is more structural and profound, it responds to many more factors, some of which are associated with the accelerated growth of its population, as in many Latin American cities.
