Lagoon: The Latest Architecture and News

In Lagos, a city with a complex urban fabric that includes historical buildings and vast interpretations of contemporary architecture, lies PatrickWaheed Design Consulting (PWDC). This design practice, Co-led by Adeyemo Shokunbi, aims to contribute to a Nigerian architectural language through the renaissance of local materials. Through explorations anchored in local laterite, they have developed the material as a modern finishing technique, investigated its potential as a natural dye, discovered new ways to employ its thermal properties, and now build the research prospect of other local materials. I had the opportunity to speak with Architect Shokunbi, who discussed the initial inspirations and investigations during the construction of two building projects (Mad House & Abijo Mosque) in Lagos. These projects brought the Laterite finishing technique to life and now help build the case for a Nigerian architectural language.

Land reclamation from the sea has become a popular phenomenon in coastal development. It is the most preferred solution to the need for land in coastal areas and has been implemented for various use cases, including flood control and agriculture. Nowadays, it has become a famous urban response to the rapid increase in coastal urbanization, economic activity, and global population. Countries like China and the Netherlands lead the chart on the amount of land area reclaimed. However, most reclamation projects today take place within urban centers in the global south. Cities in West Africa, East Asia, and the Middle East produce these new lands as economic forerunners for their commercial industry and as platforms to house luxury residences.

But the relationship between the design and production of reclaimed lands and the response of water in ocean environments is complex. It requires a symbiotic relationship with water bodies for stability but can provoke natural forces when negligently imposed on the sea. Ocean water behaviors, including tidal accumulation, sea level rise, connection to wetlands, and aquatic biodiversity, can question the success or failure of land reclamation projects in different contexts.

African cities are expected to experience a significant increase in population over the next 30 years. According to United Nations projections, these cities will welcome an additional 900 million inhabitants by 2050. This demographic shift will create both opportunities and challenges that will reshape the nature and structure of these cities. These challenges include the need for economic growth, increased demand for housing and infrastructure, and the development of supplementary transportation systems. So far, most African cities have responded to this rapid population growth with sprawling horizontal development patterns that expand the fringes of the city, increase social fragmentation, and ultimately lead to greater car dependency.

The threat of climate change is looming before us. Sea level rise concerns over 410 million people at risk of losing their livelihoods. Coastal cities are choked with high-rise buildings and traffic-laden roads, consuming land insufficiently. Synthesizing these problems, architects across the world have proposed a potential answer - floating cities. A future of living on water seems like a radical shift from how people live, work, and play. Vernacular precedents prove otherwise, offering inspiration for what our cities could morph into. As world leaders discuss courses of action to tackle climate change at the COP27 climate summit in Egypt, ArchDaily dives into the concept of radical water-based settlements.

Half of the world’s population now lives in cities, according to UN-Habitat’s latest reports. While this number is set to increase to two-thirds by 2050, urban challenges are growing exponentially, making it more crucial than ever, to transform our cities. Annually, the world population review assesses the growth of cities and the number of residents living in metropolitan areas, to understand global evolution trends. In 2022, the list of the top 20 most populated countries remained similar to the 2021 edition, with a slight change in numbers and positions. Tokyo kept its status as the world’s largest city, with 37 million inhabitants, while Delhi and Shanghai, followed in second and third positions.

Comparing the results to the 2021 edition, the only decrease that can be seen in the top 20, involves both Japanese cities, Tokyo and Osaka. The rest of the list had, on average, a growth of 1.8% in the total of people residing in metropolitan areas. In fact, African cities Kinshasa in the Democratic Republic of Congo and Lagos in Nigeria gathered the highest rates, with respectively a 4.39% and a 3.54% increase in residents in 1 year. The largest city in the American continent is still Sao Paulo in Brazil, followed closely by Mexico City and Buenos Aires in Argentina, further down the table. In Europe, Istanbul is the most populous, with more than 14.5 million residents.

According to the United Nations’ latest report on populations in cities, by 2030, “urban areas are projected to house 60 percent of people globally and one in every three people will live in cities with at least half a million inhabitants”. Growing in both size and number, cities are hubs of government, commerce, and transportation, and in 2021, the world’s 20 largest cities are home to half a billion people. In fact, one in five people worldwide lives in a city with more than 1 million inhabitants.

Below, we have rounded up the top 20 megacities in the world of 2021, according to the number of people that live in their metropolitan area. While Tokyo is the largest city on a global level, with a total of more than 37 million residents, the majority of the most populous cities in the world are in the two most populated countries, China and India. Among these, we have 5 metropolises in China, Shanghai, Beijing, Chongqing, Tianjin, and Guangzhou, and 3 in India, Delhi, Mumbai, and Kolkata. The largest city in the American continent is Sao Paulo in Brazil with 22 million people, followed by Mexico City and Buenos Aires in Argentina. Istanbul takes the 13th position with one part of the city lying in Europe and the other part in Asia.

For the past two weeks, cities across Nigeria were hit by protests against the notorious Special Anti-Robbery Squad (SARS), a police unit setup in 1992 to fight armed robberies. The anti-SARS protesters are calling for the unit’s disbandment, due to its high-handedness, extra-judicial killings, extortion, and numerous human rights abuses.

Tragically, the protests came to a brutal climax on October 20, with the shooting of protesters at the Lekki Tollgate by gunmen believed to be agents of the Nigerian state. This led to casualties, which are currently a subject of controversy: the Lagos State government concedes that two persons lost their lives; groups like Amnesty International insist the figures are much higher.

Parpend, a design studio from Lagos, Nigeria, interviews every year a group of architects to discuss their favorite projects and how they created them. Believing firmly that design should be a fusion of function and expression, statements are compiled in a publication in order to highlight the designers’ creative process to achieving good design.

Entitled “PERSPECTIVE”, this edition of the report, destined for designers and non-designers alike, examines 4 projects with 3 designers: Seun Oduwole, Principal designer at SI.SA talks about the JK Randle Centre for Yoruba History and Culture, on Lagos Island; Tosin Oshinowo, Director at cmDesign Atelier discusses a Bahá’í temple competition and an art space for Victor Ehikhamenor, a prominent Nigerian artist. Moreover, James Inedu-George, Head of Design at HTL Africa explores a mosque contest.
