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.
Innovative materials play a crucial role in shaping the future of architecture. They offer not only novel ways to craft buildings but also sustainable and efficient solutions to address pressing environmental challenges. Architects and designers are now more than ever exploring and integrating innovative materials into their projects. By harnessing the unique properties of these materials, they create structures with new visual languages while also being environmentally friendly.
As part of our year-in-review, we reflect on the innovative materials that were featured. These materials delved into the concepts of recycling agro-waste, adapting bio-based products, transforming local materials, and decarbonizing concrete. The objective was not only to offer alternatives to traditional construction practices but also to help reduce carbon emissions and promote a more sustainable built environment. In this dynamic field, these materials demonstrate the potential to revolutionize building design and construction in diverse contexts, paving the way for a more sustainable and resilient future.
The Climat de France is a French colonial social housing project in Algeria designed by Fernand Pouillon and currently renamed Oued Koriche. Located approximately 8km west of the country’s capital, Algiers, it was built from 1954 to 1957, right in the middle of the Algerian War of Independence. The project has several buildings with different scales. Its most prominent structure is a large rectangular building that houses 3000 dwellings, along with a spacious interior square similar to a Roman forum and exterior windows inspired by the mosaics found in Islamic architecture.
This social housing scheme has a complex history, involving the integration of Algerians into the French lifestyle, the use of modern architecture to challenge traditional Muslim ways of living, and the transformation of its collective square into a site of protest and rebellion.
Local communities are more than just a collection of buildings and infrastructure. They possess a distinctive architectural character that mirrors their history, culture, and values. As part of our year in review, we take a deep dive into the top narratives that examine the architectural identity of different local communities.
These stories explore a wide range of topics, including unique geographic territories, cultural tribes, iconic landmarks, communal collaboration, and socio-ecological urban planning. Through these narratives, we uncover the captivating tales behind the buildings and public spaces that shape certain cities and towns.
Located 270km north of Dakar, the capital of Senegal, and near the border with Mauritania, is the Island of Saint-Louis. It is a prominent colonial city in West Africa, known for its blend of Mediterranean architecture with a tropical climate. Saint-Louis was founded by the French Colony in 1659 as its first trading post on the Atlantic coast of Africa. It later became the capital of French West Africa (AOF) and Senegal. However, it lost this status in 1902, which led to its economic decline.
This complex history has made Saint-Louis a melting point for different layers of architecture and urbanism. The island showcases a grid urban form with double-storey villas, which is typical of 19th-century French colonial urbanism. Additionally, it features tropical courtyards, shaded balconies, 1920s art déco houses, and early '30s modern civic buildings. However, due to its economic and infrastructural isolation, this architecture and urban heritage have continuously degraded. Therefore, it seeks new interventions for the conservation, restoration, and re-adaptation of the city.
Buildings that are designed to layer stories and memories, evoke a sense of aspiration, define cultural narratives, and build a national identity will always be important in all societies. When buildings have this power to shape communities, make an impact on a city’s image, and change the course of socio-economic growth, then they can be identified as iconic. Though the term “iconic” is subjective, it is one that pushes the boundaries of architecture in any context. It calls for spatial originality, proposes innovative material technology, and necessitates a radical socio-economic investment to be realized.
However, since the economies of developing countries in the global south cannot meet the requirements of these architectural structures, is there a more suitable socio-economic model for monumental structures in this context? Can the incremental principles of small adaptable changes and growth be applied to the finite iconic aspiration of this architecture?
Rammed earth is one of the oldest methods of constructing walls and still holds great potential for modern earth construction. One aspect of this potential is the gift of its colors and layers, which become visible as the formworks are removed, revealing a layered character. As a process that involves the layer-by-layer compression of gravel, sand, silt, and clay, its resulting appearance is a horizontal stratification of earth tones, material content, and curing procedures. This colorful appearance of rammed earth walls can be controlled and explored through patterns, texture, pigmentation, and natural clay colors, offering an opportunity to push its boundaries within architecture.
CPC concrete slabs are based on the technology of "carbon pre-stressed concrete," which originated from a long-term research project conducted by the Zurich University of Applied Sciences Winterthur (ZHAW) and Silidur AG, Andelfingen. These panels are reinforced with thin, pre-stressed carbon strands, allowing them to be three to four times thinner and lighter while maintaining the same load-bearing capacity as traditional reinforced slabs.
CPC's innovative approach to concrete panel production reduces material usage by 75% and minimizes the carbon footprint of concrete production. ArchDaily interviewed Professor Josef Kurath from the Department of Architecture Design and Civil Engineering at the Zurich University of Applied Sciences (ZHAW), who collaborated with CPC Construction in developing these concrete panels. We discussed his perspectives on decarbonizing architecture, the inspiration behind the development of CPC panels, a comparison with traditional concrete, and the potential for scalability and accessibility in the future.
The built environment is responsible for approximately 42% of annual global CO2 emissions. During a building's lifespan, half of these emissions come from its construction and demolition. To decarbonize architecture and control global emissions, it is important to rethink and reduce the upfront or embodied carbon impacts of demolitions, as well as implement sustainable construction strategies for buildings. Demolitions typically involve dismantling, razing, destroying, or wrecking buildings and structural parts, leading to unsustainable levels of carbon emissions, material depletion, waste, and pollution. These hasty methods of ending the life cycle of a building have negative impacts on the environment, material components, and recycling strategies. Therefore, there is a clear need to re-think the way in which we approach the end of a building or infrastructure project's life towards a more sustainable system of deconstruction.
Seratech's technology, developed by Sam Draper and Barney Shanks, eliminates the CO₂ footprint of concrete and reduces carbon emissions in construction. This innovative process uses silica, a waste product from flue gases, as a carbon-negative cement replacement in concrete. By incorporating silica, the required amount of Portland cement is reduced by 40%, resulting in the production of carbon-negative concrete. This groundbreaking technology won the 2022 Obel Award for its focus on embodied emissions.
The Obel Award is an international award that promotes architecture in the service of both people and the planet. Seratech was the fourth winner of this new international prize for architectural achievement, preceding this year's 'Living Breakwaters' by SCAPE Landscape Architecture. ArchDaily had the chance to interview Sam Draper, CEO of Seratech, about the company's role in building a sustainable construction industry and their plans for scaling their innovative process.
Rayon, an innovative online design tool that aims to create a new collaborative approach to developing "mundane buildings" within the city, has been selected as part of ArchDaily's 2023 Best New Practices. Founded in 2021 by Bastien Dolla and Stanislas Chaillou, it is a collaborative design software that brings together professionals in the architecture, engineering, and construction (AEC) industries. The software company believes that there is a “culture of the ordinary” in architecture. This culture represents an ecosystem of buildings that may seem unremarkable or aren't impressive landmarks in the city. However, these buildings and their construction professionals make up 90% of the urban fabric and contribute to the design culture that collectively gives identity to the city. The founders believe previous software generations have neglected this culture and propose Rayon as a novel tool to fill that gap by enhancing collaboration and user ergonomics.
Tropical Africa boasts vast forests that cover 3.6 million square kilometers of land in West, East, and Central Africa. These forests provide valuable timber resources that significantly impact sectors, such as the furniture, fuel, and paper industries. However, interestingly, timber is seemingly absent in the contemporary architecture of the countries in this region. While architectural taste plays a role, the main reasons for this absence can be attributed to the wood industries' inability to meet the requirements of availability, affordability, aesthetic appeal, durability, and climatic and structural performance of timber. The wood industry in tropical Africa is mainly composed of informal and small-scale operations, focused primarily on sawing logs rather than refining wood for architectural or structural purposes. Despite this, the large number of informal enterprises in the region presents an opportunity to reshape the wood industry and utilize the local forestry resources to construct timber buildings.
Protest has always been a powerful tool for creating change, and public spaces provide a platform for social engagement in societies. As part of the International Day of Democracy, we examine Africa, its series of emerging protests in the past year, and how citizens in various countries question political justice, demand better living standards from their government, and interrogate their nation’s sovereignty. With demonstrations ranging from organized large-scale marches to smaller spontaneous outbursts, residents of these countries have explored public spaces in symbolic and significant ways to amplify their voices. These spaces include public squares with cultural and historical meaning, sites of political buildings, or makeshift protest areas such as roads and open areas. Through this, African cities show how people make these spaces their own and how the power of their conglomeration cannot be ignored in unwrapping the democratic essence of public spaces.
Timber has been a popular source of construction material for thousands of years. Through sawing, milling, and other engineered wood conversion processes, various wood forms have been created and applied in products, furniture, and architecture. However, these processes can sometimes alter the basic lines of wood structure. The stems can be split, grain patterns changed, and some woods, such as oak and cedar, are easily reduced while others can become intractable. This led to the exploration of whole timber forms in ancient structures, such as log cabins, which layered timber in different cross-sections to form home profiles. Through design, the use of trunks or branches of trees in their entirety can accentuate their innate mechanical properties for structural sustainability. Although these practices are fairly absent in contemporary building techniques, new technological innovations expand the prospects of timber construction in architecture.
The concept of a city can be viewed as a constantly evolving system where both architects and users contribute to its design and redesign. While its framework may start with planners or designers, the character of the urban fabric is ultimately shaped by the societies and generations that inhabit it. The question of "city authorship" often arises in the context of masterplan design. Can architects and urban planners determine the extent to which a city will evolve through its initial design? The answer is no. User authorship then acknowledges that city planning should not be approached like building design, where designers attempt to predict every aspect of shape, pattern, behavior, and culture. Instead, it recognizes the role that people play in shaping the urban fabric through their personal taste in architecture, the development of neighborhood personality, and ongoing redesign that contributes to the story and spirit of a place. These factors should be considered in the initial design by engaging ideas related to future expansion, adaptable infrastructure, and empowering citizens to contribute to the city's architecture, thus making the city design democratic. This article explores conceptual radical cities where designers embrace the ideas of user authorship and the constant evolution of ephemeral architecture.
Our daily lives involve constant communication with the city. As we move through different spaces, we ask ourselves questions like "Where am I now?", "Where am I headed?", "What am I looking for?", "What is this building for?", and "How do I experience this space?" While spatial encounters may feel intuitive, environmental graphic design (EGD) provides the answers by serving as an important interface between us and the built environment. It involves the design of graphic elements that merge with architectural, landscape, urban, and interior designs to make spaces more informative, easier to navigate, and memorable. EDG comprises three major elements: text, shape, and color. Text and shapes typically encapsulate the graphic information, but color projects it, amplifies it, and helps communicate it within the packed scenes of the city. In spatial experiences, we perceive colors first, since our senses mostly register visual sensations. Therefore, the strategic use of color is critical for environmental graphics to provide a layered experience of identity imagery, sense of place, and emotional connection.
Art has always been a means for people to connect with space, and art movements have served as a platform for exploring new relationships with architecture. By incorporating art into buildings and interior spaces, they have been transformed, resulting in a fusion that creates beautiful, inspiring, and spiritually uplifting environments. Throughout history, various art movements, such as the Renaissance in the 17th century, Baroque in the 18th century, and Art Nouveau, Art Déco, and Bauhaus in the early 20th century, have had a significant impact on architecture. Architects drew inspiration from the ideals, concepts, stylistic approaches, and techniques of these movements, using them to create large-scale habitable structures. As the home is a fundamental expression of an architectural movement and the simplest canvas to exhibit the artistic ethos of any particular era, studying the interior spaces of houses provides a detailed picture of art's influence on spatial organization, furniture design, product patterns, and user interaction.
African societies' cultures are intrinsically linked to color. From fabrics to clothing, products, sculptures, and architecture, various societies explore rich and vibrant colors that are vivid, expressive, and joyful. Through different shades, hues, contrasts, motifs, and ornamentations, colors are embraced as an unspoken language, a palette for storytelling, and a sense of cultural identity. Although the use of color in African societies may seem decorative on the surface, it is extremely symbolic, with a deep sense of history behind it. Traditional African architecture is a prime example. Ethnic societies have endowed their homes with color through ornaments and motifs, expressed it with religious and cultural patterns, employed it on facades to tell familial stories, and created labyrinths of communal architecture that not only celebrate color but explore its ethnic meaning.
