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.

Buildner has announced the results of the Dubai Urban Elements Challenge, a landmark international design competition organized in strategic collaboration with Dubai's Roads and Transport Authority (RTA). With a total prize fund of 2,000,000 AED (approximately €500,000), the initiative represents one of the most significant publicly funded global design competitions focused on urban transformation.
The competition was conceived as a forward-looking procurement and innovation platform for one of the world's fastest-evolving metropolitan environments. Participants were invited to propose modular, climate-responsive urban elements—seating systems, shading devices, lighting infrastructure, wayfinding components, rest areas, and micro-retail structures—designed to enhance pedestrian life and strengthen Dubai's public realm identity.
On February 5, 2026, Almaty, Kazakhstan's largest metropolis, was officially declared the host city of the 2029 Asian Winter Games. The Host City Contract was signed between the Olympic Council of Asia (OCA) and the National Olympic Committee of the Republic of Kazakhstan during a ceremony in Milan, Italy, one of the host cities of the ongoing Winter Olympics. Established in 1986 in Sapporo, Japan, the Asian Winter Games will mark their tenth edition in 2029 and are held approximately every four years. The announcement follows an earlier decision to postpone the Games, which were originally scheduled to take place in the Trojena ski resort, masterplanned by LAVA and currently under construction as part of the NEOM mega-project in Saudi Arabia.
Cities around the world share a common goal: to become healthier and greener, supported by civic infrastructure that restores ecosystems and strengthens public life. The question is how to reach this. Global climate targets, local building codes, and municipal standards increasingly guide designers and planners toward better choices. Still, many cities struggle to translate these frameworks into everyday, street-level comfort and long-term ecological protection. What happens if the city is no longer treated as a traditional city, but as a national park?
National parks operate through systems of protection that treat land as a network of ecological relationships rather than a collection of isolated sites. They establish a shared baseline for what must be preserved, maintained, and made accessible over time. When this logic is applied to the urban environment, success can inspire pride and a sense of shared responsibility among designers, policymakers, and residents, fostering a collective commitment to health, habitat, and civic infrastructure.
January 26 marks the International Day for Clean Energy, an initiative aimed at raising awareness and mobilizing action for an inclusive transition from fossil fuels, such as coal, oil, and natural gas, to power generation systems with lower greenhouse gas emissions and fewer pollutants. The term "clean" signals a fundamental shift away from extractive, finite, and exhaustible energy sources toward systems based on renewable resources or on capturing energy embedded in natural processes. In a world grappling with climate change, clean energy plays an important role in reducing emissions and expanding access to reliable power. However, being labeled "clean" does not exempt these systems from the impacts associated with their production, deployment, and commercialization. In this context, architectural knowledge related to space, materiality, and habitation becomes relevant for supporting a transition toward energy systems that are sustainable over time. As stated by the United Nations, the science is clear: to limit climate change, reliance on fossil fuels must end, and buildings must be heated, lit, and electrified through clean, accessible, affordable, sustainable, and reliable power sources.
India's built environment has, in recent years, gained visibility through a growing number of transformative architectural and infrastructure projects. Cities and towns scale faster each year, despite looming concerns around climate and economic volatility. The nation has shown resilience in balancing rapid urbanization with resource constraints; this is no small feat. India's architectural practices rarely rely on novelty alone; they are built on systems that have existed for centuries. Through ArchDaily's Building for Billions, recurring stories have highlighted the social intelligence and adaptive capacity embedded in these practices, revealing an architecture that operates less as isolated form and more as infrastructure.
In 2025, India's most consequential design projects unfolded largely out of sight. While public attention gravitated toward museums, cultural landmarks, and visually arresting façades, the architecture that most decisively shaped daily life existed underground, at the city's edges, or inside secured compounds few citizens would ever enter. Sewage networks were rebuilt, flood tunnels bored beneath dense neighborhoods, substations lifted above floodplains, and data centers multiplied across peri-urban landscapes. These were not peripheral works of engineering; they were the spatial systems that allowed Indian cities to remain functional through record heatwaves, erratic monsoons, and accelerating urban growth.
As preparations advance for the Milano Cortina 2026Olympic Winter Games, set to take place from February 6 to 22, 2026, this edition introduces one of the most geographically wide-ranging configurations ever implemented for the Winter Olympics. Extending across two cities, two regions, and two autonomous provinces, the competitions will be staged over more than 22,000 square kilometres of Northern Italy. Metropolitan venues in Milan are paired with longstanding Alpine centres in Cortina d'Ampezzo, Livigno, Bormio, Anterselva, and Val di Fiemme, creating a framework that bridges urban and mountain contexts. More than 90 per cent of the venues are existing or temporary facilities, reflecting a strategy centred on adaptive reuse, selective upgrades, and long-term integration into regional sport and cultural infrastructures. Nearly 2,900 athletes will compete in 116 events, including the debut of ski mountaineering and several new mixed-gender formats that signal evolving approaches to winter sports programming.
Faced with the combined forces of population growth, economic prosperity, and urban expansion, cities are witnessing a significant rise in the movement of people and goods—mirroring the evolution of diverse mobility systems within urban environments. As technologies advance and modes of transport evolve, the adaptive reuse of train carriages, airplane cabins, and other service infrastructures reveals opportunities to explore their creative potential. Materials, technologies, and design tools converge around a shared goal: refurbishing and repurposing disused structures to give them new life.
Infrastructure has long defined the backbone of cities by linking people, landscapes, and economies through systems that often go unnoticed until they fail. Today, as global challenges demand more adaptive and human-centered responses, architects are rethinking what infrastructure can be: not just a framework for movement and utility, but a catalyst for ecological restoration, cultural continuity, and civic imagination. The following unbuilt projects, submitted by the ArchDaily community, explore this expanded role of infrastructure, where airports, bridges, industrial parks, and pedestrian networks become architectural expressions of connection and care.
This week's architectural developments highlighted how design operates as a form of social and culturalinfrastructure, linking care, community, and context across scales. From London's reinterpretation of the almshouse model to the transformation of urban gateways in Phnom Penh and Tirana, architecture reflected a shared interest in spaces that foster connection and adaptability. Parallel to these urban and infrastructural works, new cultural projects in Paris and Hanoi explored how museums and performance spaces can renew public institutions through material experimentation and spatial flexibility.

OUALALOU+CHOI has won the international competition for the design of the new Casa Sud Train Station in Casablanca, Morocco. Based in Paris and Casablanca, the architecture and urban design practice led by Tarik Oualalou and Linna Choi is recognized for its work exploring the relationship between architecture, infrastructure, and public life. The winning proposal envisions the new station as both an infrastructural hub and a civiclandmark, addressing the needs of a rapidly expanding metropolis while contributing to the urban and social fabric of Morocco's economic capital.
In Jacques Tati's Mon Oncle (1958), architecture itself becomes a character: sliding doors, an automatic fountain, gates that emit mechanical sounds, devices that both enchant and frustrate the inhabitants. The comedy arises precisely from the fact that these seemingly trivial systems silently shape everyday life. More than six decades later, the observation seems prophetic. In contemporary buildings, countless systems work autonomously and discreetly, going unnoticed when they function well. Among them, automatic doors, traditionally seen as secondary elements, are emerging as part of a new "invisible infrastructure": connected, efficient, and intelligent systems that support comfort, sustainability, and operational resilience.
In the early years of the New York City subway system, natural light played a dominant role in the illumination of subterranean spaces. The architecture emphasized a connection to the sky, often through skylights planted in the median of city avenues above — lenses in the concrete sidewalks.
However, it proved extremely difficult to keep the skylights clean, and light eventually stopped passing through. Subway authorities moved toward an almost exclusive reliance on electric lighting. While this allowed for greater flexibility in station design, permitting construction at any location and depth, it also created a sense of disorientation and alienation for some passengers.
For the design of Lower Manhattan's Fulton Center, Arup, in conjunction with design architect Grimshaw sought to reconnect the century-old subway system with the world above.
