“Casa Batlló” in the centre of Barcelona is a UNESCO World Heritage Site since 2005 and an icon of the city, the highest expression of Gaudí’s work and modernism. The challenge was to restore the intricate shapes of the interior of the building without changing its original design. “The Casa Batlló restoration project has been awarded the Special Mention in the 2021 European Award for Architectural Heritage Intervention for offering a respectful and technically high quality restoration, which makes possible the resurgence of an initial project that has partially disappeared and achieves the recovery of an altered work, respecting its identity. Amongst other interventions, the restoration project allowed for the recovery of the original stuccoes of the Noble Floor” (source:

What key aspect(s) of the New European Bauhaus initiative does the project fit best with?

How does the project contribute to these aspects?

The New European Bauhaus’ claim is: beautiful, sustainable, together. We believe this project embodies all these ideas. Plaster allowed for the beautiful shapes to be rediscovered, it is one of the most sustainable materials available and the project came to fruition thanks to the work of many people, all of them specialists in their own domain.
