Commissioned in 2012 following an international design competition, Snøhetta's BusanOpera House is under construction on the city's North Port waterfront, with major works scheduled for completion in late 2026 and an opening planned for 2027. Conceived as the first opera house in South Korea's second-largest city, the project redefines the traditional opera house as an open and inclusive civic institution. Rather than operating solely as a venue for performance, the building is envisioned as a public destination that supports everyday use, collective experience, and long-term cultural engagement within Busan's evolving urban landscape.
The Busan Slope Housing project by OMA addresses urban redevelopment on the steep hillsides of Busan, South Korea, drawing on the city's topographical complexity and historical settlement patterns. Developed in collaboration with the BusanArchitecture Festival and the Department of Housing and Architecture, the project explores strategies to rethink hillside neighborhoods while responding to both contemporaryhousing needs and the social and spatial legacies of these areas. Rather than replacing these areas with conventional high-rise estates, OMA envisions a flexible, context-responsive framework that integrates contemporaryhousing typologies with the site's inherited structure.
The Bureau International des Expositions (BIE) announced yesterday, on Tuesday, November 28, that Riyadh, the capital city of the Kingdom of Saudi Arabia has been selected to host the 2030 World Expo, by securing the necessary two-thirds majority of votes in the first round. Marking another milestone for the Gulf, following Dubai's Expo 2020 and Qatar's hosting the FIFA World Cup in 2022, this five-yearly event draws millions of visitors and investments. Under the theme, "The Era of Change: Together for a Foresighted Tomorrow", Expo 2030 Riyadh will run between 1 October 2030 and 31 March 2031.
Competing against South Korea's port city of Busan and Rome in Italy, Riyadh won the bid with 119 votes, while Busan received 29 votes, and Rome got 17 votes out of the 182 members of the Paris-based Bureau International des Expositions (BIE). Other explored subjects were the themes of “Transforming Our World, Navigating Toward a Better Future” by Busan and “People and Territories: Regeneration, Inclusion and Innovation”, for Rome.
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.
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.
UN-Habitat and blue tech firm OCEANIX unveiled the design of the world’s first prototype for a sustainable floating city, to be hosted by Busan. The project is intended to provide a scalable framework of development for coastal cities facing land shortages and rising sea levels. With a population of 3.4 million people, Busan is the second-largest city in the Republic of Korea and, at the same time, one of the most important maritime cities, making it a suitable environment for deploying the floating city prototype.
