Red clay roof tiles appear in many architectural traditions around the world, despite the cultures being geographically or historically distant. However, this isn't necessarily surprising. Clay is an abundant and accessible building material worldwide, with some studies and other sources suggesting it comprises approximately 10-13% of the Earth's soils. Red tiles, in particular, are often a product of the local soil's mineral content and the firing process. Their widespread use across unrelated regions is less about shared cultural influence and more about material logic: clay is cheap, durable, and easy to work with using simple tools and techniques. In Vietnam, for example, there is a unique and visible tradition of clay tile use that dates back centuries. Regions like Vinh Long, nicknamed the "kingdom of red ceramics", have an abundance of this material, supporting a long history of tile-making. In some parts of Vietnam, these tiles are known as Yin-Yang tiles, due to the concave and convex shape in which they are formed during production.

Understanding the temperature gradient in a building is essential in cold or temperate climates, where airtight enclosures and continuous insulation are used to prevent heat loss. However, this approach is not suitable for tropical areas like Central America, where the climate is marked by a consistent alternation between wet and dry seasons rather than four distinct ones. Factors such as proximity to the sea, elevation, and local topography influence microclimates across short distances, but high humidity remains a common challenge. Sealed, airtight walls with no ventilation can quickly become breeding grounds for mold, making the thermal strategies of temperate climates problematic. In response, local designers have developed alternative approaches that embrace, rather than resist, the outdoor environment, allowing airflow and evaporation to manage interior comfort.
It shouldn't be too surprising that architectural concepts were traveling around the globe long before the online spread of information. While many regions share certain historical events and hence references (such as colonization and the mid-20th-century independence movement/ turn of political systems), others might have simply developed parallel solutions to similar climates and material availability. Additionally, it was only natural that with the dissemination of a more uniform architectural pedagogy acquired while studying abroad, followed by the internet boom, we would find almost twin projects from every corner of the world. While these might look nearly identical from some angles, they might bear different layers and stories. Then again, they might also display the same reasoning and prompts shared by counterparts from across the seas.
Humid environments present some of the most complex challenges in architectural design. From the tropical monsoon season of Southeast Asia to the equatorial heat of Central Africa, these environments demand solutions that account for intense moisture, high temperatures, and the constant battle against mold, decay, and stagnation. Yet, for centuries, communities in these regions have developed architectural techniques that do not fight against humidity but instead work with it, leveraging local materials, climate-responsive design, and passive cooling techniques to create sustainable and livable spaces. By considering atmosphere as a sensory and climatic phenomenon, architects will craft spaces that are not only evocative but also responsive, adaptive, and sustainable.
In late 2024, an important addition was made to the growing literature on Modern architecture in Africa. "Modernism in Africa: The Architecture of Angola, Ghana, Mozambique, Nigeria, Rwanda, South Africa, Sudan, Tanzania, Uganda" was published by Docomomo International and Birkhäuser, shedding light on multiple previously unpublished buildings. The book has a focus on education, although other building types are included. Amongst these are several university buildings in Nigeria which are explored here. Like other Modern buildings on the continent, they illustrate historical narratives of independence, decoloniality, international relations, and architectural education.

Reflecting on 2024, numerous architectural exhibitions have opened worldwide, addressing various themes, exhibition formats, and featured architects. Architectural design and architecture practice influence our daily lives in subtle and often unnoticed ways, where the end-users embrace built environments as they are. This reaction may arise from a combination of factors, such as a sense of powerlessness to enact significant change after a building is constructed or the experience of growing up in environments over which individuals had little or no agency in shaping. For these reasons, architectural exhibitions serve an essential purpose, offering society a chance to pause, reflect, and critically examine the myriad issues that surface during designing and building. These issues are often overlooked or need to be acknowledged, as practitioners may prioritize delivering projects within strict timelines over exploring more profound reflections.
In 2024, museums, galleries, and curators responded to the evolving challenges within the built environment with various approaches. Some exhibitions questioned the ethics of building materials and the practices behind supply chains, drawing attention to the broader implications of material choices. Others focused on documenting architectural movements worldwide, emphasizing their cultural and historical significance and the urgent need to preserve and adapt rather than replace them with entirely new builds. These efforts highlight the role of exhibitions in raising awareness about pressing issues while fostering a more critical dialogue about the architectural discipline.
The mid-twentieth century marked a transformative period for Africa as 29 countries achieved independence between 1956 and 1964, signaling the dawn of the nation-state across the continent. This era resonated with a spirit of liberation and progress, paralleling the global movements of that time, such as the establishment of international organizations like the United Nations (1945) and the Organization of African Unity (1963). Within this context, Modernist architecture emerged as a powerful symbol of national identity, ambition, and the collective aspiration for a brighter future. As newly independent nations sought to define themselves apart from their colonial pasts, the adoption of Modern Movement principles facilitated the construction of key infrastructures, such as convention centers, parliament buildings, and hotels, as well as the development of architectural education, as native-trained architects begun to either replace or cooperate with foreign-born professionals.
This article inaugurates a new series titled Rediscovering Modernism in Africa, aiming to explore the architectural legacy of the Modern Movement in Africa, highlighting its role in nation-building and the evolution of architectural education, while shedding light on the architects and movements that shaped this transformative era.
As, one by one, the African nations gained their independence in the middle of the twentieth century, building programs were central to the process of nation-building. In several of those countries, this included the construction of the state's institutions such as their respective national assembly. These buildings not only facilitate the legislative process but also symbolize the new nation's governance, identity, and aspirations. The period of independence movements also coincided with the introduction of the Modern Movement across the continent, which was associated with progress and a break from the colonial past. Across Africa, some national assemblies were constructed early and were part of the nationalization process that preceded independence, while some were constructed long after.
Two museums in Africa built in the mid-twentieth century carry the name 'National Museum.' They reflect the story of their respective nation's history and are tied to notions of national identity. Both are also examples of fine architecture built on the principles of Modernism, a movement associated with nation-building in Africa. However, their inception and purpose followed very different paths. This article explores the under-reported architecture of the National Museum of Ghana in Accra and the Sudan National Museum in Khartoum.
Honduran architect Angela Stassano is contributing to Central America's architectural landscape with her applied research regarding bioclimatic designs. Based in San Pedro Sula, Honduras, her projects draw from local heritage techniques to address the needs of hot, humid tropical environments. Stassano has developed her expertise through over 30 years of hands-on research, culminating in a bioclimatic architecture guide that outlines her methods for construction in this region. One of her most notable projects, Las Casitas, is a residential complex that embodies this research. The project includes multiple energy-efficient tropical houses that harness the local climate, resulting in low energy and operational costs.
The middle of the Twentieth Century saw the independence of most countries on the African continent. Those euphoric times brought forward-looking sentiments and a wish to break with the past. As an architectural movement, Modernism was ideal for the day, and newly independent countries had extensive building programs to assert themselves as fully functioning nations.
Hotels are one type of building that illustrates the complex architectural and political history of the times. Some were built specifically to host international delegations, others to boost tourism, while some were built as strong leaders' wishes. Although a marginal building type, several hotels across Africa stand as physical records of important parts of their respective country's history. Following an exploration of the histories of West Africa's Modernist Hotels, this second article turns to East Africa to uncover the ways in which this understated typology relates to larger histories of independence and national identity.
Located north of Dakar, near the city's airport, is an architectural composition of triangular volumes known as the International Trade Fair Centre, Dakar, Senegal. Also known as the Foire Internationale de Dakar or FIDAK, this structure is an iconic example of 60s modernism in West Africa. It synthesizes the complexity of simple forms within vernacular spatial patterns. Completed in 1974, it reflects the post-colonial ambition of the country and has grown as an adaptive spatial framework for major cultural events and exhibitions.
Every year, Earth Day, celebrated on April 22, presents us with an opportunity to contemplate the conditions of our planet and our impact upon it. Generating around 37% of global carbon emissions, the construction industry has an important, often detrimental, role to play, thus placing an increasingly urgent responsibility on architects and builders to devise strategies for reducing this number. Still, the built environment represents the habitat for most of humanity, and so it has the potential to protect and shelter people from the risks posed by the changing climate. Read on to discover a collection of articles delving into the strategies available at urban and architectural scales for mitigating the effects of climate change and minimizing the industry’s impact upon it.
When we think of the word "tropic," the image that typically comes to mind is an exotic space, characterized by perpetual warmth and humidity, with frequent and heavy rainfall nurturing lush vegetation. Throughout history, this tropical climate has been romanticized as a paradise and criticized for potentially fostering weakness due to its perceived clemency.
Thankfully, those judgments and associations have been relegated to the past, paving the way for theoretical and practical projects that outline the advantages and disadvantages of living in a tropical climate. These projects acknowledge the various strategies to enhance human adaptability within these distinctive climatic conditions.
Bruno Stagno from Costa Rica not only reflects on how responses to the environment can be the main foundation for the inspiration and identity of architecture but also suggests going a step further, envisioning architecture for an entire latitude.
We discussed his current concerns and motivations, the shortcomings and necessary innovations in tropical cities, the relationship between academia and professional practice regarding the environment, and, above all, projections for the future of Costa Rican architecture.
Architecture in the Global South often embodies a rich cultural heritage and craftsmanship, incorporating vibrant colors, intricate patterns, and symbolic elements. It also tackles the challenges faced by developing economies, such as limited resources, rapid urbanization, and social inequality, by promoting inclusive and community-driven design solutions. As installations and pavilions serve as radical templates for interrogating these architectural ideals and seeking innovative solutions, we present the top architectural installations as part of our year-in-review. They encompass curated exhibitions like the Venice Architecture Biennale, as well as permanent pavilion structures in specific contexts that delve into local materials, waste reuse, and the reinterpretation of historical narratives.
