During 2024, the Canadian Centre for Architecture (CCA) launched a three-part documentary and exhibition series titled Groundwork, exploring alternative modes of practice in light of the current climate crisis. The process began with a series of studio visits in search of offices addressing substantial questions for contemporary architecture through practice, culminating in the selection of three projects: Xu Tiantian's "minimal intervention" museum on Meizhou Island, Carla Juaçaba's community pavilions in a coffee field in Minas Gerais, and bplus.xyz (b+)'s European Citizens' Initiative for a new legal framework to facilitate the renovation and transformation of existing buildings. The latter, HouseEurope!, was recently recognized as the winner of the seventh edition of the OBEL Award and was showcased at the international exhibition of the Venice Architecture Biennale 2025.

Studio Libeskind has released new images of the design for the transformation of the Boerentoren tower, one of Europe's earliest skyscrapers, located in the heart of Antwerp, Belgium. Developed in collaboration with Belgian architecture firm ELD, the project reimagines the 1932 Art Deco landmark as a new public cultural hub that will house The Phoebus Foundation's art collection. The design includes the addition of exhibition spaces, a panoramic viewing platform, a rooftop sculpture garden, and new restaurants and bars. According to the architects, the original architectural features will be preserved while introducing a new architectural feature, which they are calling the "Reimagined Crown." Initially announced in 2022, the project has now received preliminary approval from the Flemish Heritage Agency and the City of Antwerp.

In certain parts of the world, construction is still dominated by wet systems—concrete, masonry, and cementitious materials that are poured, cured, and fixed in place. While this has long been considered the norm in some south-east Asia countries, such as Singapore, Thailand, Malaysia, and China, in most of these regions, they typically share a common trend where labor is relatively inexpensive. This serves as one of the reasons to make concrete more easily available, as one of the typical downside of concrete is its intensive labour cost - this further differentiates concrete as a cheaper and more efficient material system to be building out of.

However, not enough considerations in the region are given to the sustainability aspect when using these wet construction materials,often overlooking the significant drawbacks of its material lifecycle and the difficulty to recycle it without downcycling - making it one of the more unsustainable materials available to be built out of.

What does a change in use and/or scale in buildings imply? How can a church or chapel be transformed into a home? While the architecture of many contemporary sacred spaces shows a remarkable capacity for adaptation and evolution, the creative boundaries of many professionals extend beyond their conception as structures of spirituality or worship. Globally, the conversion of large churches and small chapels into private residences reveals a wide field for intervention and exploration, one that can preserve, restore, adapt, and/or renew the character of spaces originally conceived for other uses and scales, which for various reasons have been abandoned, become obsolete, or now require transformation.

The installation and exhibition representing Estonia at the 19th International Architecture Exhibition of La Biennale di Venezia is curated by architects Keiti Lige, Elina Liiva, and Helena Männa. Titled Let Me Warm You, the national exhibition explores different dimensions of sustainability by questioning whether insulation-driven renovations in Estonia are simply compliance measures to meet European energy targets or whether they can also serve as opportunities to enhance the spatial and social quality of mass housing districts. To make this point, the Estonian installation covers the façade of a Venetian building with insulation panels, replicating how they are commonly installed in Estonia for mass housing renovations.

What can our existing buildings teach us about building for the future? In a time of dwindling resources, architects are increasingly called to engage in dialogue—with the site, its history, and the untapped potential of what already stands. Rather than defaulting to demolition and new construction, the future of architecture may rest in uncovering the possibilities for innovation within buildings that have already stood the test of time.

Condensation, maintenance, and humidity are three familiar challenges that continue to test the buildings we design and construct. Whether stemming from climate conditions, limited airflow, or the specifics of construction detailing, these factors affect not only the durability of materials but also the everyday comfort and performance of inhabited spaces. When the setting is an aquatic center or an indoor swimming pool, the demands are even greater. The constant presence of steam, moisture accumulation, and the risk of mold can compromise both energy efficiency and the user experience. In such environments, ventilation and access to daylight, beyond their aesthetic value, become essential tools for maintaining equilibrium, enhancing indoor comfort, and ultimately improving how the space is perceived and utilized.

Søren Pihlmann is the curator of the Danish Pavilion at the 2025 Venice Architecture Biennale. The exhibition, commissioned by the Danish Architecture Center, is titled Build of Site, and focuses on exploring sustainable architectural practices through the lens of reuse and resourcefulness. Pihlmann's proposal transforms the existing Danish Pavilion, located within a historic building complex in the Biennale's Giardini, into an active exhibition space for material experimentation. The installation highlights techniques that incorporate recycled and bio-based elements. The Pavilion offers visitors the opportunity to observe ongoing experimental processes, witnessing how building resources are creatively reimagined for new uses. In this on-site interview, ArchDaily editors spoke with the curator about the ideas behind the project and the challenges its execution represents.

The city of Buenos Aires is vast in its area and has a heterogeneous and variable urban fabric in terms of scale. Much of the residential neighborhoods are made up of a mixed-use fabric, where the predominant constructions from several decades ago are the so-called "casa chorizo" and horizontally owned houses, commonly known as PH (Propiedad Horizontal). It is interesting to review how, over the years, these constructions have been modified due to changes in building regulations, which allowed the creation of new typologies, mainly responding to new ways of living within the city. The renovation of these constructions, many of which are used for residential purposes, has also been a conscious response to avoid overbuilding in an already densely populated city. While these projects have been a recurring practice in Buenos Aires for several years now, many young architects of new generations are taking on these challenges, thus generating a trend that seems to have no end and where we find new solutions in each renovation.

Boston City Hall, one of the most debated examples of Brutalist architecture in the United States, has significantly transformed since its conception. Designed by Kallmann, McKinnell, and Knowles and completed in 1968, the fortress-like concrete exterior and geometric austerity have long divided public opinion. Critics, including a former mayor, called for its demolition for decades arguing that its imposing design was inhospitable, inefficient, and most importantly, not beautiful. However, rather than tearing it down, Boston has chosen to renovate and revitalize the structure, demonstrating that contested Brutalist architectural styles can be adapted for a more sustainable future.

The 2025 Pritzker Prize has been awarded this year to Chinese Architect Liu Jiakun. Born in Chengdu in 1956, he grew up in the densifying city, before attending and graduating from the Chongqing Architecture and Engineering College (Chongqing University) in 1982 with a Bachelor of Engineering degree in Architecture, and becoming one of the first college graduates to be tasked with rebuilding the country during the Chinese transition period. However, it wasn't until many years later that the architect understood that "the built environment could be used as a medium for personal expression". It was then that his endeavors and career took off, with Liu Jiakun starting his practice in 1999, and participating in more collaborative works across China and Europe. Based on his experiences, his works are anchored in his understanding of reality and a respect towards China's multi-traditional history and internal diversity; all while achieving a seamless balance between architecture and nature, tradition and modernity.

These concepts do not obstruct his consciousness of human needs and the importance of community spaces. Through his projects, Liu Jiakun proves that spaces can affect human behavior and become positively evocative. A public space such as those he's created can be conducive to a benevolent atmosphere that provides rest and collaboration. "such as my pursuit of narrative and poetry in design." The comprehensiveness of Liu Jiakun's works makes it easy not to be constrained by stylistic or aesthetic limitations or requirements. He just follows what the site, natural landscape, pre-existing urban frame, and citizen needs might require. The physical result is a mix of all of these with the predominant vernacular traditions.

Renzo Piano Building Workshop (RPBW), in collaboration with Holger Meyer Architekten, has won the competition for the new Midstad project in Frankfurt. Led by Joost Moolhuijzen and Erik Volz, the design reimagines the future of European city centers as resourceful and multifunctional. The project involves a 35,000 m² rehabilitation of an existing department store on the Zeil in Frankfurt's city center, integrating a six-story mass timber extension and a mixed-use, community-driven program. The project involves reconstruction during ongoing operation, partial demolition, and the expansion of the existing department store.

The change of the calendar year marked the culmination of several processes in the world of renowned architecture firms. Between December 2024 and February 2025, Gensler unveiled a rendering of a Manhattan redevelopment project, Foster + Partners released renderings of a new hotel and luxury residences in Brazil, and Herzog & de Meuron announced the completion date for the new Memphis Art Museum. International competitions revealed their results, highlighting the winning project of the young firm Unformed Design, as well as the collaboration between the Portuguese Fala Atelier and the Swiss Continentale on an educational architecture project. These projects showcase the broad scope of architectural design, from the detailing of a high-end project's relationship with nature to the urban renewal potential of a programmatic conversion project.
