Twenty years after its ideation, Herzog & de Meuron's controversial Tour Triangle in Paris is reaching completion. The triangular, all-glass tower located in the city's 15th arrondissement topped out at 42 stories on April 24, 2026. The project's progress was marked by opposition, financial roadblocks, and legal disputes before construction began in 2022. The 180-meter tower is now the third-tallest building within Paris city limits, behind the 330-meter-tall Eiffel Tower, the 231-meter-tall The Link in La Défense, and the 210-meter-tall Tour Montparnasse. The building will retain this title indefinitely due to a skyscraper ban reinstated in 2023 by Mayor Anne Hidalgo, following persistent opposition to tall buildings in the city. The recent progress was documented by photographer Stefano Candito, ranging from an urban view of the building to a close-up look at its nearly completed structure.

Rotterdam-based firm MVRDV has announced a new milestone in the development of its Tour & Taxis Towers, a mixed-use project in Brussels, Belgium. The design was commissioned by real estate investor and developer Nextensa in 2021, within the framework of a site-specific land use masterplan also designed by MVRDV. The two-tower project combines offices, housing, and public amenities across 58,000 m², forming a landmark in the neighbourhood and reaching 126 metres at its highest point. Recently granted construction permission, the project is designed to reduce embodied carbon through the use of a hybrid structure and lightweight façade elements, aiming to minimize the use of concrete in both the structure and foundations. From the early stages, the firm has employed its CarbonSpace software to guide these decisions.

This article is part of our new Opinion section, a format for argument-driven essays on critical questions shaping our field.

The modern sustainability project is built on the promise that evolving technologies can reconcile urban and economic growth with ecological responsibility. By the metrics developed by the built environment professions and the policies adopted by governments, progress is tangible and accelerating: buildings consume less energy per square foot than they did a generation ago, vehicles emit fewer pollutants per mile, and urban infrastructure is more integrated and measurably cleaner in many cities. And yet total resource consumption continues to rise. Sustainability, as currently practiced across the built environment professions, has become a strategy for optimizing consumption rather than reducing it. Until the profession is willing to question the scale and structure of demand rather than the efficiency with which that demand is met, its most celebrated achievements will continue to fall short of the problem they claim to address.

The ReGreeneration project, a Horizon Europe project led by Inetum and supported by C40 Cities, ARUP, Placemaking Europe, and several others, operates as an active collaboration with local governments, private companies, academia, and civil society organizations at the intersection of urban regeneration, green public spaces, and neighborhood-scale design. Its premise addresses how European cities are built and maintained and how they experience a changing climate, arguing that cities must fundamentally change to remain livable under accelerating climate pressures.

Photographer Paul Clemence documented the International Gateway Centre (IGC) in West Kowloon, a mixed-use development by Zaha Hadid Architects in Hong Kong, as it approaches completion. The photo series captures the project at a stage where its overall massing, facade systems, and spatial organization are largely realized, while final works continue across public and interior areas. Clemence's close-range views highlight the vertical shading pleats, the curvature of the glazed envelope, and the transitions between structural and environmental elements, underscoring how the building's formal language is resolved through construction.

As housing shortages and affordability challenges intensify across global cities, this week's architectural discourse centers on how design, policy, and adaptive strategies intersect to shape the future of urban living. Initiatives range from grassroots movements and legislative reforms aimed at expanding access to housing to innovative models that rethink ownership, development, and community engagement. At the same time, architects are reimagining existing structures and districts, transforming underused offices, historic landmarks, and unfinished buildings into mixed-use, culturally significant, or publicly accessible spaces. Across scales, these stories illustrate how architecture negotiates scarcity, value, and social priorities, demonstrating its capacity not only to produce new buildings but also to recalibrate urban environments in ways that balance heritage, sustainability, and human experience.

Cities are slowly reshaping themselves. Walkable streets, bike-friendly networks, and mixed-use neighborhoods are becoming planning priorities as climate goals, changing lifestyles, and remote work reshape daily patterns. Yet even as these people-centered ideas gain momentum, most cities still rely heavily on private cars, creating a tension between the urban futures we're designing for and the mobility habits that persist today.

This tension has pushed architects and developers to rethink one of the hardest pieces of the urban puzzle: parking. Mixed-use buildings are multiplying, stacking homes, workplaces, and services into tighter footprints, and every square foot has to work harder. The challenge is no longer simply where to put the cars, but how to integrate parking in ways that support density, livability, and long-term adaptability—allowing cities to evolve without letting vehicles dominate their form.

UNS has revealed images of SeoulOne, a master plan designed for Hyundai Development Company (HDC) in Seoul, South Korea, intended as a new model for multigenerational living. The project, already under construction on a brownfield site in the northeast of the city, reimagines an existing industrial site and railway area as a 405,000 m² car-free neighborhood for a multigenerational community. A never-sleeping, green master plan for Seoul, SeoulOne is envisioned as a mixed-use mini-city where all essential services for people of all ages are available within a 10-minute walk. The design includes 24/7 residential towers, retail spaces, offices, a hotel, sports facilities, daycare centers, senior living facilities, and a medical center, offering permanent services within walking distance. More than 30% of the site is dedicated to vegetation, including pocket parks, roof gardens, water gardens, and a forest walk, creating a year-round green village.
