Have you ever heard of “agrowaste design”? This is how Filipino-Ghanaian architect Mae-Ling Lokko titles her work, a pioneering research initiative on the use of biomaterials in architecture. Alongside the growing demand for food production and housing in the 21st century, there is an equally fast-growing flow of material resources in the form of agricultural byproducts. This has the potential not only to close product lifecycle loops but also to foster forms of generative citizenship through upcycling.

Lokko seeks to rethink product cycles and use within the construction industry through a circular economy—where nothing is wasted and everything can be reused, even after it becomes obsolete.

Planning and implementing projects to prioritize active travel has been a requirement in Brazilian cities since 2012, under the National Urban Mobility Policy. Walking is the most significant mode of transport in urban life, accounting for 39% of daily trips in Brazilian cities. Furthermore, walkable cities are more sustainable, resilient, healthy, social, and democratic.

To this end, the Walkable City Award, organized by SampaPé! with support from ITDP Brasil and Walk 21, sought to discover and recognize public sector projects and initiatives implemented in recent years to prioritize walking. Its inaugural edition received 28 eligible projects from 16 different cities across 10 states and the Federal District, representing every region of the country except the North. All submissions are featured on a map of public walkability initiatives available on the Award website to inspire future projects.

A team of Brazilian architects was awarded third place in the international Toronto Affordable Housing Challenge, organized by Bee Breeders. Developed by Ana Luisa Rolim (Coletivo-rt arquitetura), Isabella Trindade, Beatriz Bueno, and Larissa Falavigna, the project LaneWAY OF LIVING: Green Villages in The Heart Of Toronto’s Urban Fabric proposes a series of units featuring a cross-laminated timber (CLT) structure and a charred wood exterior finish.

The COVID-19 pandemic deepened the crisis of urban centers, especially those whose vitality, like Rio de Janeiro's, is closely tied to commercial and service activities.

Lockdown mandates and the rise of remote work substantially reduced foot traffic, which previously sustained a range of local businesses—especially bars and restaurants, small retailers, and cultural venues.

Renewable energy storage, particularly for wind and solar, remains a challenge. However, researchers at Chalmers University of Technology in Sweden are taking a major step toward creating an eco-friendly cement-based battery. Still in the prototype stage, the project focuses on the construction industry. 

In search of sustainable and scalable materials, researchers Emma Zhang and Luping Tang, from the Department of Architecture and Civil Engineering, developed a new concept for rechargeable batteries. The process begins with a cement-based mixture containing small amounts of short carbon fibers to increase conductivity and flexural toughness. A metal-coated carbon fiber mesh—iron for the anode and nickel for the cathode—is then embedded into the mixture. This is the first concept of its kind in the world.

Non-Visual City: An Audio Guide to Downtown São Paulo is an auditory and acoustic project essay exploring urban relationships and their events. Centered on how visually impaired people perceive the city, the proposal seeks to challenge and engage with their urban experiences to enhance their right to the city, autonomy, and citizenship. The spatial focus of this case study is the area where the open streets project for pedestrians was implemented in São Paulo's Centro Novo (República district). 

When studying indeterminate architecture, there is an almost natural instinct to label it. If not to label it, then to resolve it so that it can—even if only momentarily—become something more concrete. But what happens if we do not try to define it?

In 2019, along with a few colleagues, I visited the Bonpland Building, designed by the Argentine firm Adamo Faiden. Before our visit, during a conversation with friends, I tried to explain the concept behind many 21st-century porteño buildings: the logic of site occupation structured as front and rear blocks connected by a centralized circulation core; the building envelopes; and, in the case of the Bonpland building, a floor plan where the only structural elements were the vertical circulation and the wet cores. I commented on the building's exercise in indeterminacy and received a highly interesting response: I was told that this lack of resolution in the interior layouts was simply laziness on the part of the architects.

Transforming cities built for cars into environments that prioritize the well-being and mobility of all people can make urban centers more resilient and inclusive. Changing ideas and practices so deeply ingrained in city planning is no trivial task. However, a new report by WRI Brasil, "Complete Streets in Brazil – Promoting a Paradigm Shift", shows that the seeds of change have been sown and are already bearing fruit.

The publication documents the results of four years of work by the National Network for Low-Carbon Mobility, an initiative by WRI Brasil and the National Mayors Front (FNP) that brought together 21 Brazilian cities committed to shifting the paradigm of street and city design.

The construction industry's role in the current climate crisis is deeply concerning: spanning material production, construction, and building operations, the sector is one of the largest emitters of greenhouse gases. At the same time, urban populations are growing at historic rates, and when looking at the development of large cities—which are major energy consumers—it seems that reducing the discipline's impact relies on small-scale community and individual initiatives rather than broad political and professional actions.

History shows us various local techniques and materials that have proven sustainable over time through the efficient use of resources that require no heavy industrial processing and eliminate the need for long-distance transportation. In some cases, at the end of their life cycle, materials like adobe and timber can even be returned directly to the environment.

The remarkable research paper “A Long History of a Short Block,” by Bill Easterly, Laura Freschi, and Steven Pennings, analyzed the development of a block on Greene Street in New York's SoHo neighborhood over four centuries. Throughout this period, the city remained in a constant state of development, demonstrating that the question “What is the ‘original character’ of a neighborhood?” is far more difficult to answer than it seems.

To begin with, the skyscraper-filled Manhattan we know today is a relatively recent development in its history. Before the Dutch arrived in what they would call “New Amsterdam” in 1625, the region was dominated by forests and wetlands—a rich ecosystem that even included bears and wolves.

Steel frame is a system composed of galvanized steel profiles, with a thickness between 0.80 mm and 3 mm, cold bent, and assembled as structural frames, with vertical and horizontal studs. To wrap the structural profiles, OSB, cementitious or plasterboard sheets are used, which can be finished and painted internally and externally. Inside the walls, insulating materials can be included, such as mineral, glass wool, or others, to increase the thermal acoustic insulation. In the steel frame system, all the electrical and hydraulic parts are installed before closing the panels, making the process more efficient and without breakage and material waste. Cleanliness of the work, efficiency and speed are key points in this constructive system that is widely spread around the world.

The Brazilian Center for Steel Construction (CBCA) has announced the winners of the 14th CBCA Competition for Architecture Students. The nationwide competition was open to students from architecture schools and colleges across the country, focusing on the theme "Health and Well-being."

Arquicast has shared with us a recent interview with one of the most important Brazilian architects of her generation, whose work perfectly exemplifies the diverse responsibilities that architects can assume in their contribution to society. Maria Josefina de Vasconcellos, better known as Jô Vasconcellos, shares a bit of her history and her plans for the future.

Before stamps and digital printing, wallpaper was a luxury item and a status symbol, as every design had to be hand-painted by artisans. As a symbol of wealth, it emerged to replace tapestries and paintings in 16th-century European homes. In Brazil, for instance, wallpaper only became economically viable in the 1930s, and its widespread popularization was only realized in the 1960s.

On August 17, Brazil celebrated National Heritage Day, 21 days after a protest set fire to the statue of Bandeirante Borba Gato in the southern zone of São Paulo. This contradiction opens up an important discussion: how are we constructing memory in our cities? What are we valuing as our country's heritage? 

The term historical and cultural heritage refers to the tangible and intangible creations of a given culture within society. What defines a cultural asset as heritage is its historical and social relevance, which can be linked to collective and individual memory, as it is through these memories that we understand the past. From an architectural perspective, the term heritage is constantly associated with historic buildings that typically embody Catholic religious values or the bourgeois lifestyle of the elite.

Well-designed environments are essential to reduce the risk of accidents and response times in the event of a fall. For architects, designing safe cities and homes is crucial, especially in light of global demographic trends. Developing an architectural project through thoughtful design and correct product specification is, first and foremost, an act of care and concern for our older relatives and fellow citizens. It is essential to ask, "For whom?" and "What are their needs?" so that, from there, we can think about how to improve their quality of life.

This is a conscious invitation for architecture to play an active role in today's society—a positive shift that delivers both design and quality of life.

Spending more time at home made many people realize that designing interior spaces goes beyond mere personal "taste"; rather, their environments directly influence our comfort, mood, and quality of life. This perspective has altered how we view the bathroom itself, prompting a search for solutions that liven up this space and rescue it from the standard monotony in which it is typically designed. To that end, we have searched our archives for several examples that break this mold, showcasing spaces that bring more personality to the home and enhance the well-being of their users. 

Disability and the diversity of bodies and people should be an engaging subject for architects: it is about lived experience, problem-solving, and designing a better built environment.

While the topic involves critical theory and aspirations for collective life, it is often viewed merely as a compliance-driven field—or worse, a sensitive subject fraught with outdated terminology and archaic habits of thought. Typical design routines do not always account for the variety of human bodies.

“From the problem of locomotion derive all other problems of urbanization.” It was in 1882 that the Spanish urbanist Arturo Soria y Mata made this assertion, and in response to it, created and implemented the concept of the linear city. Based on a functionalist doctrine, this city model abandons traditional structures such as squares and blocks, subordinating the design to circulation paths in its most rational spatial configuration: the straight line.

Ruins of once-elegant buildings eloquently illustrate the worst that can happen to a city after the end of an economic cycle. Wealthy families no longer have the resources to maintain their estates, and even middle-class buildings are partially abandoned when their owners, unemployed or struggling, relocate in search of opportunities elsewhere.

Left vacant and unused, physical heritage slowly degrades. Urban history is filled with examples across all eras and continents: Rome at the end of classical antiquity, Venice at the dawn of the modern era, Paraty after the shift in the Gold Route, and Detroit today.
