From building codes to mobility restrictions and new diplomatic roles within city governments, climate policy is increasingly being shaped at the local level through a widening range of legislative and institutional tools. Cities as varied as Sydney, Boston, New York, Paris, Miami, and dozens across Latin America are adopting targeted strategies that reflect their distinct environmental pressures and governance structures. These initiatives range from all-electric and net-zero construction requirements, to traffic-control measures designed to curb the social costs of private vehicle use, to emerging forms of urban diplomacy that coordinate responses to rising temperatures and biodiversity loss. Together, these approaches illustrate how territorial management is evolving in response to the accelerating climate crisis, and how local governments are experimenting with regulation and collaboration to confront challenges that are at once global and deeply place-specific.
The potential of existing buildings to shape cities and communities in flux through reuse and adaptation is the key focus of HouseEurope! and their activism: addressing the pressing challenge across much of Europe, where it is often easier, cheaper, and faster to demolish buildings than to renovate. For decades, construction policies, industrial practices, and market systems have favored new development, often undervaluing the cultural, social, and environmental significance of existing structures. For their work advocating systemic change in architecture, HouseEurope! received the 2025 OBEL Award under the theme "Ready Made." In a conversation with ArchDaily, collective members of HouseEurope! Alina Kolar and Olaf Grawert discussed the organization's approach to architecture, policy, and collective action.
Across cultural districts and civic centers, this week's architectural developments highlight how institutions and city governments are reshaping their futures amid shifting environmental, social, and economic pressures. New museum and opera projects signal ongoing commitments to expanding public cultural infrastructure, while the debate surrounding Dallas' modernist City Hall illustrates the tensions that arise when questions of heritage meet rising maintenance demands and redevelopment pressures. At the same time, municipalities are advancing new regulatory tools to confront climate challenges, from electrification standards in Sydney and Boston to mobility restrictions and emerging forms of urban diplomacy. These developments reflect an increasingly complex landscape in which architectural environments evolve through a combination of cultural ambition, environmental targets, and shifting models of public decision-making.

Edinburgh, Scotland's capital, has long been recognized for its rich cultural history and intricate urban fabric. The city thrives within its museums, tenement housing, and shops nestled in Georgian buildings. In 2022, Time Out ranked Edinburgh as the world's best city, citing its efficiency across community building and urban systems such as public transport. However, as climate change makes its effects progressively visible at an urban level, the city inevitably runs into a pressing dilemma: how to sustain this quality of life in increasingly difficult conditions.
The journey toward this balance unfolds through several interconnected strategies, such as retrofitting, adaptive reuse, circular design, and community collaboration, each contributing to Edinburgh's evolving vision of a sustainable urban future.
HouseEurope!, a registered non-profit organization focused on promoting the social and ecological transformation of Europe's built environment, has received the 2025 OBEL Award. Presented annually by the Henrik Frode Obel Foundation, the award recognizes architectural contributions with the potential to drive meaningful change. Aligned with this year's theme, "Ready Made," the OBEL Award Jury selected HouseEurope! for its efforts in raising awareness and fostering public engagement around the need for a shift in construction and housing practices across Europe.
The Empire State Development (ESD) Board of Directors has approved a major office-to-residential conversion project at 5 Times Square, New York City, as announced by the New York state government. Originally built in 2002 as the headquarters for Ernst & Young, with Kohn Pedersen Fox (KPF) as the design architect, the building has been largely vacant since the corporation vacated the premises in 2022, with vacancy rates remaining around 75 percent. Gensler's proposal aims to repurpose this underutilized office space into a mixed-use complex, introducing up to 1,250 new homes, including 313 permanently affordable units.
In recent weeks, cities around the world have introduced new policies, recovery efforts, and infrastructure projects that reflect growing pressure to adapt to climate realities. From Southern Europe to South America and the United States, these urban updates address both immediate challenges and long-term shifts in how the built environment is governed, designed, and inhabited. Some initiatives focus on regulation, tightening building codes in fire-prone areas or reforming aging safety systems, while others spotlight large-scale investments tied to global events such as COP30 and the Venice Architecture Biennale. This edition of Architecture Now gathers a selection of city-led actions and collaborative efforts that point toward a more resilient, responsive future for architecture and urban life.
The Los Angeles City Council has approved the revised Citywide Adaptive Reuse Ordinance (Citywide ARO), which is planned to take effect in 2025. Building on the success of the 1999 ordinance, which facilitated the creation of over 12,000 housing units in Downtown LA, the updated policy aims to address the city's ongoing housing crisis and repurpose underutilized buildings.
HouseEurope! is the European Citizens' Initiative advocating for EU legislation to simplify, reduce the cost of, and make more socially equitable the renovation and reuse of existing buildings, has officially begun its signature gathering period. The initiative aims to curb demolition driven by speculation and foster a construction industry that prioritizes the potential of existing public and private buildings. As a tool of direct democracy, European Citizens' Initiatives allow citizens to propose legislation at the EU level. For the legislation to be officially considered and implemented by the European Commission and EU member states, it requires the support of 1 million European citizens from at least seven EU countries. The initiative opened for signatures on February 1st, 2025 and will remain open until January 31st, 2026.
It has been nearly three weeks since one of California's most devastating wildfires began, triggering an immense effort to combat the blaze and mitigate further damage. As firefighters work to contain the remaining flames, the city braces for its first significant winter rainfall, raising concerns about flooding and landslides that may exacerbate the already extensive destruction.
Amid these challenges, the wildfire has spurred widespread reflection at local and global levels. Discussions have emerged on topics such as the insurance system, firefighting infrastructure, water resources, global warming's role in high-wind fire conditions, and the impact of landscape design, particularly the use of non-native vegetation.
Devastating wildfires across Los Angelesa have resulted in widespread destruction, displacing thousands of residents, and necessitating a rapid and efficient rebuilding process. Two executive orders have been issued to expedite the rebuilding process, one by Los Angeles Mayor Karen Bass and another by California Governor Newsom, both intending to remove significant regulatory hurdles and expedite project approvals.
New York City has implemented the first congestion pricing scheme in the US, charging drivers up to $9 per day to enter a designated zone south of Central Park, encompassing areas like Times Square and Wall Street. The initiative aims to alleviate chronic traffic congestion, improve air quality, and generate revenue for public transportation improvements, addressing New York City's ranking as the world's most congested urban area for two consecutive years. The plan went into effect Sunday, January 5th, 2025.
A look at most of the cities within Latin America reveals striking commonalities across countries, from Mexico down to Argentina: most cities have a well-defined area known as "El Centro" (The Center), anchored by a main plaza (Plaza Mayor), flanked by a church on one side and key buildings like the city hall on another. This is no coincidence, as it can be traced back to an urban planning system established during the Spanish colonization of the Americas in the 17th and 18th centuries. It gave standardized guidelines for city design across its viceroyalties. Unlike French and English colonies, Spanish settlements adhered to regulations that contributed to the emergence of a shared urban identity, with cities displaying similar spatial logic and architectural cohesion despite differing scales and contexts.
The Spanish city of Barcelona, one of Europe's top tourist destinations, has announced a plan to ban apartment rentals to tourists by November 2028. The move, announced by Mayor Jaume Collboni, aims to alleviate the long-standing housing crisis, lower prices for residents, improve livability, and increase the city’s affordable housing stock. Over the past 10 years, the rise in short-term rentals has driven rents up by 68%, and the cost of buying a house by 38%, contributing significantly to a cost-of-living crisis.
On April 10, 2024, the New York Landmarks Conservancy bestowed the Preservation Leadership Award to author and urbanist Roberta Brandes Gratz. A longtime preservation activist, Gratz served on the City’s Landmarks Preservation Commission. She also led the successful effort to restore the Eldridge Street Synagogue, now the Museum at Eldridge Street. The following is a slightly edited version of the speech Gratz delivered at the 34th annual Lucy C. Moses Preservation Awards.
In an effort to find effective strategies to mitigate the adverse effects of climate change, the Biden-Harris administration has released a draft of a new legislative initiative that strives to impose a National Definition for Zero Emissions Buildings. Overseen by the U.S. Department of Energy (DOE), the draft proposes a standardized and verifiable base for defining the common minimum conditions for such buildings, as well as pathways for transparent verifications by public and private entities. DOE has now launched a ‘request for information' asking for feedback from industry, academia, research laboratories, and other stakeholders before finalizing the document.
