Landscape and urban design studio SLA has unveiled the design for the public realm and streetscapes of Toronto's new 39.8-hectare waterfront community. The urban landscape project "Ookwemin Minising" is located in the Port Lands, an industrial and recreational district southeast of downtown Toronto, currently undergoing urban revitalization to transform the area from a former industrial zone into a naturalized river valley, mixed-use neighbourhoods, and public parkland. The overall transformation is being led by Waterfront Toronto, a publicly funded, not-for-profit corporation established in 2001 to oversee the regeneration of the area, as part of a broader government initiative to renaturalize urban areas and increase housing density. The redevelopment of Ookwemin Minising is expected to be completed in phases between 2031 and 2040.
In 2012, Cities Without Ground: A Hong Kong Guidebook offered one of the clearest documentations of a condition that many residents experience intuitively but rarely name: Hong Kong's dependence on elevated, second-storey urbanism. Through drawings and careful mapping, the book captured how the city's pedestrian networks are routinely lifted above the street—separating people from traffic, extending commercial frontage beyond ground level, and negotiating a hilly topography where "flat" circulation is often an engineered achievement. Since its publication, these systems have only grown in prominence—not only for their sheer spatial complexity, but for the way they recast public space as something continuous yet selective, connective yet curated.
This fascination, however, has always carried a parallel unease. Elevated passages can be generous and effective, offering sheltered movement and reliable connectivity. Yet they also raise persistent questions: where do these routes lead, who gets to connect, and what kinds of programs are invited—or excluded—by this "privileged" level of circulation? The second-storey city does not simply bypass vehicles; it can also bypass the street as a civic stage. Over time, it risks shifting architectural attention away from ground-level public life, relieving designers from having to negotiate pedestrian scale, frontage, and the messy reciprocity of the street. In its worst moments, the result is a landscape of podium clusters and sealed megastructures—buildings that perform connectivity at Level 2 while remaining indifferent to the neighborhood at Level 0.
In recent decades, cities across the world have seen an increase in the demolition of elevated concrete freeways. Taipei, Seoul, Portland, and Boston, for example, have all seen the rise and fall of these infrastructures to give way to parks and new urban regeneration ideas. In other cases, like Montreal in Canada, some people opposed the freeways even before they were built, effectively rerouting viaducts, preserving heritage, and freeing waterfront views. For San Francisco, in the United States, the story of the Embarcadero Freeway is one of those narratives that serves as a case study of the city's mid-century infrastructural ambition, people's reaction to the project, and its eventual reversal in favor of urban connectivity.

The city of Barcelona has announced the five finalist teams selected to advance in the international competition for Liceu Mar, a new cultural venue planned for the Port Vell waterfront. Promoted by the Gran Teatre del Liceu in collaboration with the Port of Barcelona, the project is conceived as a second venue for the historic institution, expanding its artistic and civic role while strengthening its international presence. Bringing together a group of internationally recognized and locally rooted practices, the shortlist underscores the project's global relevance, with the winning proposal expected to be announced in autumn 2026.
Set along the outer breakwater of Port de Cap-d'Ail, located next to Monaco, the Beach House occupies a threshold between land and sea. Surrounded by water and docked boats, the building sits in close dialogue with the harbor, exposed to the shifting light, reflections, and atmosphere of the Mediterranean. Within this setting, the house reads almost like another vessel moored along the harbor wall.
When architect Dave Rowles began work on the project, however, the residence offered little of this character internally. The former private home had been stripped back almost entirely, leaving a raw concrete shell. The renovation, therefore, began with a fundamental question: how can an interior capture the qualities of its surroundings? Rather than competing with the powerful maritime context, the design focused on creating a calm, material-driven interior that frames and amplifies the beauty and experience of the surrounding landscape crafted from oak, cedar, marble, and stainless steel details. In collaboration with barth, a company specializing in interior craftsmanship, Rowles transformed the concrete structure into a cohesive interior, where natural materials, light, and refined detailing define both the interior and exterior spaces.

Hariri Pontarini Architects and Snøhetta have been selected to design the new Ontario Science Centre in Toronto. Announced in February 2026, the 400,000-square-foot facility will anchor the site's ongoing transformation through a 220,000-square-foot building defined by a series of scalloped, modular volumes. A central component of the proposal is the physical integration of the existing Pods and the historic Cinesphere via elevated connections and a continuous public promenade. Construction is expected to begin in Spring 2026, with completion anticipated in 2029 as part of a broader waterfrontredevelopment strategy.

ManresaIsland Corp. has unveiled the final vision for Manresa Wilds, a 125-acre waterfront park planned on a former power plant peninsula along Long Island Sound in Norwalk, United States. Developed in collaboration with landscape architecture firm SCAPE and architecture studioBIG, the proposal outlines the transformation of a polluted and long-inaccessible industrial shoreline into a publicly accessible coastal landscape. Following the receipt of a stewardship permit from Connecticut's Department of Energy and Environmental Protection in December 2025, the project will move forward in phases, beginning with the opening of the 28-acre Northern Forest in spring 2027. Subsequent phases, extending into the early 2030s, will deliver the majority of the restored landscape and the adaptive reuse of the 1960s-era power plant as a year-round civic and educational hub, opening nearly two miles of coastline that have been closed to the public for decades.
Urban masterplans remain an exploratory ground for unbuilt speculation, offering insight into how cities might recalibrate mobility, ecology, and collective life in response to accelerating environmental and social pressures. In this Unbuilt edition, submitted by the ArchDaily community, the selected projects bring together a range of large-scale proposals that examine urban centers, waterfront districts, infrastructural corridors, and cultural landscapes as spatial frameworks for reconnection and resilience. Rather than treating the masterplan as a rigid blueprint, these projects approach urbanism as an adaptive system shaped by climate, topography, infrastructure, and public space.
Across varied geographies, from Northern European town centers and Mediterranean coastal districts to Central Asian polycentric hubs and Gulf megacities, the proposals explore diverse architectural and urban strategies. They range from park-led civic transformations built over highway tunnels to elevated pedestrian networks above active transport systems, mixed-use blocks structured by historic planning logics, marina developments integrating environmental stewardship, and research-driven models for equitable landscape urbanization.
Zaha Hadid Architects has released images of its design for the redevelopment of the waterfront along the Zhedong Canal in Hangzhou's Xiaoshan District, China. The Qiantang Bay Central Water Axis project envisions a sequence of landscaped parklands, terraces, and gardens along the canal basin, proposing the transformation of former industrial areas into a green corridor extending toward the city center. The proposal adds to other recent design initiatives in the area, including Snøhetta's Qiantang Bay Art Museum, planned at the confluence of the Qiantang River and the Central Water Axis, as well as Zaha Hadid Architects' Grand Canal Gateway Bridge, a pedestrian bridge intended to connect the firm's 800,000-square-meter Seamless City masterplan on the east and west banks of the Grand Canal.
Coastal development in major cities has long been a terrain of opportunity and contention—shaped at once by the pursuit of capital (premium views, scarce land, and the promise of reclamation), by civic demands for public access and collective waterfront life, and by contemporary aspirations for sustainability and place-defining urban identity. Precisely because these agendas rarely align, extracting the full potential of waterfront sites is never straightforward.
Yet in New York City and Hong Kong, we can trace each city's ambitions—despite differing strategies, priorities, and political logics—through a set of keystone projects that anchor their coastlines. Read together, these projects reveal not only what each city chooses to value, but also what it is willing to trade off in order to build at the edge.
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 Nobel Foundation has revealed the first design proposal for the new Nobel Center, a public cultural and educational institution dedicated to science, literature, and peace. Designed by David Chipperfield Architects Berlin, the project will be constructed along Stadsgårdskajen at Slussen in Stockholm, with construction scheduled to begin in 2027 and completion planned for 2031. Conceived as a permanent home for the activities surrounding the Nobel Prize, the building aims to make the work of Nobel Prize laureates accessible to a broad public through exhibitions, public programs, and interdisciplinary exchange, positioning the center as both a civic landmark and an international point of reference.
Set to open on January 19, 2026, the Sydney Fish Market marks the first completed project within the broader renewal of Blackwattle Bay on Sydney's inner harbour. Designed by 3XN in collaboration with BVN and Aspect Studios, and delivered by Multiplex, the purpose-built facility replaces the former market with a contemporary structure that combines an operating wholesale fish market with retail, dining, and publicly accessible waterfront spaces. Positioned approximately one mile southwest of Sydney's central business district, the project reframes one of the world's largest fish markets by volume as both working infrastructure and a civic destination.
The State of Qatar announced on December 4, 2025, the selection of Frida Escobedo Studio, with Buro Happold engineers and Studio Zewde landscape designers, to design the new headquarters for the Ministry of Foreign Affairs. Intended to establish a more visible civic presence for the Qatari diplomatic service and provide public access to the Ministry complex, the project is planned for a prominent site along Doha's waterfront, transforming a significant section of the city's Corniche. Situated beside Doha Bay, the 70,000-square-meter (750,000-square-foot) project is conceived as a combination of new construction and the adaptive reuse of the historic modernist General Post Office currently on the site.

Snøhetta has been selected to design the Qiantang Bay Art Museum, a new cultural landmark within the Qiantang Bay Future Headquarters development in Xiaoshan District, Hangzhou, China. Conceived in collaboration with the Architectural Design & Research Institute of Zhejiang University Co., Ltd. and Buro Happold, the project encompasses architecture, landscape architecture, and interior design over 18,000 square meters. The museum will form part of Hangzhou's expanding downtown area along the Qiantang River, serving as an important destination for art, culture, and public life.
RSHP has announced the completion of the Barangaroo South Masterplan in Sydney, marking the realization of a 15-year redevelopment that has reconnected the city's north-western harbour edge to its urban core. Once a disused container port, the 22-hectare site has been transformed into a mixed-use, carbon-neutral precinct, integrating commercial, residential, and public spaces along the waterfront. Developed in collaboration with Lendlease following an internationaldesign competition, the masterplan is organized into three zones: Barangaroo South, a high-density extension of the Central Business District; Barangaroo Reserve, a reconstructed natural headland that reintroduces native landscapes to the harbour; and Barangaroo Central, a low-density residential area linking the northern and southern ends of the development.
