Rethinking office buildings: adaptive reuse as urban strategies

Elena Guidetti and Caterina Barioglio

Cities worldwide are increasingly confronted with the obsolescence of office buildings, particularly those constructed between the 1960s and 1980s. Often functionally redundant and technically outdated, these structures—much like the abandoned factories of earlier decades—now represent a latent resource. This session explores adaptive reuse as a critical architectural and urban strategy, capable of transforming such buildings through minimal intervention and maximum retention. Positioned between heritage conservation and climate-conscious transformation, adaptive reuse offers a meaningful alternative to demolition by engaging with the embodied energy and material continuity of the existing fabric. We welcome contributions, including case studies, theoretical reflections, or interdisciplinary perspectives that address the architectural, environmental, and social dimensions of reusing vacant office stock. Of particular interest are projects that reimagine these buildings for housing, public infrastructure, or hybrid programs through design, policy, or technical innovation. The session aims to frame adaptive reuse as a proactive, low-carbon response to today's urban and ecological urgencies.

Virtual Tour of the 14th BIAsp 

The 14th São Paulo International Architecture Biennial, Extremes: Architectures for a hot world., It has expanded beyond physical space and can now be visited from anywhere! 

The virtual tour offers a new perspective on the exhibition, which took place from September 18th to October 19th at the Oca in Ibirapuera Park, allowing for fluid, free, and intuitive navigation between the different spaces. During the visit, curatorial content, high-definition images, and details that deepen the spatial and conceptual understanding of the artworks are available. 

The platform broadens access, preserves the memory of the Biennial, and creates new ways to experience architecture. 

Visit the 14th BIAsp here!  

Explore at your own pace, revisit routes, and deepen your experiences. 

The virtual tour will soon be available on the IABsp (Brazilian Institute of Architects – São Paulo branch) website.
