As part of the UIA World Congress of Architects 2026 in Barcelona, , Architects’ Council of Europe premiered its exhibition “Form Follows Transformation: Moments that Redefine Europe’s Existing Buildings”, presenting inspiring architectural responses to one of Europe’s most pressing challenges: how to transform, reuse, and adapt the buildings we already have.
Co-funded by the European Union’s Creative Europe programme, the exhibition explores how transformation, renovation, and adaptive reuse can become central strategies for addressing climate change, supporting social needs, and preserving Europe’s cultural heritage.
Hosted at the Disseny Hub Barcelona (DHUB), the exhibition brought together 20 exemplary projects from across Europe, demonstrating how architects are rethinking existing buildings as valuable resources rather than constraints. Through innovative design approaches, circular strategies, and sensitive interventions, the featured projects show how transformation can preserve the identity of places while creating new opportunities for their future.
Following its premiere in Barcelona, “Form Follows Transformation” will travel across Europe in the coming years, creating opportunities for architects, policymakers, students, and the wider public to discover inspiring examples of transformation and exchange knowledge on the future of Europe’s existing building stock.

Rethinking Europe’s Existing Buildings
Europe’s built environment is undergoing a profound transformation. Faced with climate challenges, resource scarcity, and changing social needs, the future of architecture increasingly depends on how we work with what already exists.
“Form Follows Transformation” presents transformation not as a technical solution alone, but as a new architectural culture based on care, adaptation, and long-term stewardship. The exhibition highlights how buildings are shaped by layers of history, materials, communities, and uses, and how architects can unlock their potential through thoughtful interventions.
The showcased projects demonstrate that reuse is not simply about preserving the past. It is about creating new possibilities for the future: reducing environmental impact, strengthening communities, and generating high-quality places that respond to contemporary needs.

20 Projects Demonstrating the Potential of Transformation
The exhibition presents 20 projects selected from across Europe, illustrating the diversity of approaches to transforming existing buildings. Together, they demonstrate how architecture can respond creatively to different contexts, scales, and challenges.

The accompanying „Form Follows Transformation” publication expands this selection to 36 projects, providing a broader overview of European approaches to transformation, including cultural buildings, schools, workplaces, housing projects, landscapes, and public spaces.
A New Architectural Culture Based on Transformation

Reflecting on the exhibition, ACE President Daniel Fügenschuh highlighted the importance of recognising transformation as a fundamental shift in architectural practice: “The exhibition celebrates projects that demonstrate that this paradigm shift is not only possible, but already underway.” He emphasised the role of architects in developing innovative responses to Europe’s environmental and social challenges, showing that high-quality architecture can emerge from working carefully with existing buildings and places.

For Reto Gmür, Member of the ACE Executive Board and President of the exhibition jury, transformation requires a broader understanding of sustainability: “The crisis of our built environment refuses simple remedies. A building with a reduced carbon footprint is a beginning, not an answer. The world presents layered pathologies—ecological, social, material—and architecture, if it is honest, must respond to all of them at once.”
He further stressed the importance of understanding existing buildings as unique resources: “Every existing building carries a character of its own.” Transformation begins by recognising the qualities already present in buildings and places—their history, materials, atmosphere, and relationship with their surroundings—and using these as the foundation for future interventions.

Connecting Architecture, Policy, and Practice
The exhibition formed a central part of ACE’s presence at the UIA World Congress of Architects and complemented the policy seminar “Form Follows Transformation: Moments that Redefine Europe’s Existing Buildings”, which brought together around 200 architects, policymakers, city representatives, and experts from across Europe.
The seminar and exhibition together highlighted the need for closer links between architectural practice and policy frameworks that support the transformation of Europe’s building stock, including the Nový evropský Bauhaus, , Energy Performance of Buildings Directive (EPBD), a dále Davos Baukultur principles.
By bringing together exemplary projects and policy discussions, ACE aims to strengthen the recognition of transformation as a key pathway towards a sustainable, inclusive, and resilient Europe.

A European Exhibition and Lasting Resource
Alongside the exhibition, ACE published the “Form Follows Transformation” booklet, gathering the featured projects and providing insight into the architectural ideas, processes, and challenges behind each intervention.

The publication offers a resource for architects, policymakers, students, and all those interested in the future of Europe’s existing buildings.
Following its launch in Barcelona, “Form Follows Transformation” will continue its European journey, travelling to different locations and creating new opportunities for dialogue, exchange, and inspiration.
Through the exhibition and publication, ACE highlights a fundamental message: the future of Europe’s architecture will depend not only on what we build, but also on how we transform, adapt, and care for what already exists.
“Form Follows Transformation” is co-funded by the European Union through the Creative Europe programme.
