The 2025 edition of the Seoul Biennale of Architecture and Urbanism has announced the 24 designers commissioned to create the Walls of Public Life, a collective installation that explores how the exteriors of buildings can become more expressive, engaging, and emotionally resonant. Each contributor will produce a 2.4 by 4.8-meter building fragment, offering a reimagining of the architectural wall not as a backdrop, but as an active participant in public life. Installed along the north side of Songhyeon Green Plaza in central Seoul, the walls will form part of a larger urban intervention that includes the Humanise Wall, a four-storey, 90-meter-long installation to the south of the park.
The Benedictine Monastery of San Nicolò l’Arena in Catania, Sicily, holds within its stones the echoes of five centuries, shaped by time, varied uses, violent earthquakes, and the blazing force of Mount Etna. Its walls, silent witnesses to history, were molded both by the fire of nature and by human hands. Yet among all the transformations it underwent, none was as profound or poetic as the one led by Italian architect Giancarlo De Carlo, starting in 1980. After 30 years of dedicated work, time required to truly understand such a complex and awe-inspiring site, the former monastic residence was reborn as a university, not by force, but through revelation.
Public space has long been central to architectural thought, often framed in terms of planning, infrastructure, and regulation. From Haussmann's Paris to contemporary masterplans, architects have worked to define and formalise collective life through spatial tools. Yet, outside of these frameworks, artists have continuously offered alternative ways of understanding and inhabiting public space—ways that rely not on construction or permanence, but on presence, perception, and participation. Through actions, objects, or atmospheres, artists engage the city as a site of friction and imagination. These gestures challenge architectural conventions and invite artists to reconsider public space not as a solved form, but as a contingent and open process.
DROPCITY is an ambitious and open platform for architecture and design, located in Milan's formerly abandoned Magazzini Raccordati tunnels behind Central Station. Initiated by Andrea Caputo in 2018 and open permanently since 2024, the project reimagines 40,000 square meters into public galleries, production workshops, prototyping labs, and research spaces. The founder of the platform is Andrea Caputo, an Italian architect and researcher. During Milan Design Week 2025, ArchDaily's managing editor, Maria-Cristina Florian, had the chance to sit down with Andrea Caputo to explore his vision and plans for DROPCITY, the platform's connection to the city of Milan and its active architecture scene.
Castles and fortresses often rise from strategic, commanding positions when standing alone or integrated into urban and rural landscapes. From above, they overlook the city, bearing in their imposing structures the weight of history. With their original functions now limited to contemplation, these spaces have been undergoing revaluation and reintegration into everyday urban life. Once symbols of military or political power, they are now taking on new roles through contemporary interventions that engage with their heritage without erasing their past.

In the contemporary context, museums face contradictory sets of ideas: becoming attractions on and of themselves but presenting an understated image that shifts the attention to the exhibits, creating a safe and protected environment for the artifacts, yet opening them up to the public, becoming repositories of history yet catalysts for innovation. Searching for the balance between all of these constraints has resulted in the flourishing of diverse types of museums and cultural institutions, from those dedicated to the remembrance of a single event or persona to temporary homes for cultural events or spaces that expand their cultural offering beyond exhibition areas.
This curated selection of Best Unbuilt Architecture highlights projects submitted by the ArchDaily community that demonstrate the fusion of art, technology, and innovation within the realm of museums and cultural centers. Among the featured designs are works from renowned architectural offices, including CAA architects, NextOffice – Alireza Taghaboni, and Fentress Architects, along with several emerging firms. Ranging from a sculptural art museum in Dubai to a local cultural and recreational complex in Senegal, or an immersive science museum in Rome, Italy, this diverse compilation strives to showcase the spectrum of scales and purposes of cultural institutions.
Highway interchanges have evolved from important infrastructures that help distribute traffic to unique landmarks that define cities. As multiple road networks embrace and form distinctive sculptures, these road intersections range from singular bridge connections and roundabouts to numerous, layered and multi-layered interchanges. They twist, turn, loop, and wrap around sparse land, vegetation, or existing structures in a bid to transfer travelers from one roadway to another. However, they also create a moment of enclosure, forming partially bounded areas and a sense of space. These spaces could be viewed as liminal and transitional, with no fixed typology able to be hosted. But that blurring character calls for ideas of urban intervention to disrupt the notion of what these spaces can be. They can be readapted from car-dominant sculptures into more human-friendly places and re-integrated as extended schemes of the city's architecture.
As part of a new initiative of the multidisciplinary laboratory based in Mexico, dérive LAB presents "Shared Streets", a project with a focus on urban design that seeks to spatially transform the street so that it is governed by human relations, rather than using traffic control devices; this suggests that the street is not only a space for transportation and mobility but one in which many other social, economic and cultural activities take place.
The International Placemaking Week, presented by Project for Public Spaces (PPS) is an inspiring and engaging event designed as a global gathering of placemakers from different sectors to discuss thoughts and share strategies in order to push forward the concept of placemaking in the host city and on an international level. Previous editions took place in Vancouver in 2016, Amsterdam in 2017, and Chattanooga, Tennessee in 2019.
PPS, the nonprofit organization behind Placemaking Week, helps people create and sustain public spaces that build strong communities. In 1999, they elaborated “How to turn a place around”, a book that defined the placemaking movement, creating a guideline of 11 principles to follow in order to create vibrant community spaces.
The Chicago Architecture Biennial (CAB) and the Danish Arts Foundation (DAF) have selected Soil Lab as the winning project of a DAF Open Call for a major new commission in the North Lawndale neighborhood of Chicago. Responding to the biennial’s 2021 edition theme The Available City, led by Artistic Director David Brown, the proposal, chosen to represent Denmark at the 2021 Chicago Architecture Biennial, was imagined by an international design team that includes Eibhlín Ní Chathasaigh (Dublin), James Albert Martin (Dublin), Anne Dorthe Vester (Copenhagen), Maria Bruun (Copenhagen) and Chicago residents.
Local Collective has designed a seating made of clay for the London Festival of Architecture and Network Rail. Unveiled at London Bridge Station, the urban furniture is a result of a “competition organized by the LFA and Network Rail to create public installations that celebrate London’s shared spaces and connect people with playful encounters”.
The field of architecture has the potential to influence human relations in countless ways through the built space. In small-scale projects, in particular, the challenges of tackling the dialogue between the space and the individual are combined with the task of conveying ideas to inspire people to explore the use of these minimal spaces.
"Les Jumeaux" or The Twins is a new large-scale public urban intervention by French artist and designer Camille Walala in White City, West London. The project encompasses two pedestrian crossings and seven striking murals, created with geometric patterns and primary colors, Walala’s signature style. Moreover, Camille Walala also unveiled this month her East London intervention, a giant work of art aiming to breathe new life into the street and boost the local economy, entitled "Walala Parade".
Due to population growth and an increase in urban density and real estate prices, architects and urban planners have been pursuing alternatives for new spatial configurations for settling and housing in the cities. The multiplication of shared housing and workspaces is an example of how the field of architecture is adapting to new ways of living in society.
When urban spaces become the medium for expression, protest, criticism, and defiance, the audience is limitless. Pedestrians and bystanders of all ages and ideologies become spectators of demonstrations that walk the line between art and activism and transform the city's streets, walls, and sidewalks into canvases for diffusing ideas on a massive scale. Banksy once said that "a wall is a very big weapon. It's one of the nastiest things you can hit someone with." This call to arms has rung true for many as they take to the streets in a bid to make themselves heard.
BIG unveiled its latest intervention, the Toyota Woven City, the company's first venture in Japan. Nestled at the foothills of Mt. Fuji, the project, in collaboration with Toyota Motor Corporation, is the world’s first urban incubator pushing forward the development and progress of mobility.
