“New ideas must use old buildings,” said Jane Jacobs in her seminal book The Death and Life of Great American Cities, championing the reuse of existing building stock as a means to catalyze positive change and foster diverse urban environments. Inserting new activities within an existing framework is increasingly becoming a defining aspect of contemporary architecture, as the need for sustainable alternatives to building anew turns more urgent. From an urban perspective, adaptive reuse is a valuable strategy for revitalizing post-industrial cities, creating density and mitigating urban sprawl, or helping shrinking cities redefine their urban fabric.

One of the primary demonstration spaces for Itaipu Binacional's socio-environmental actions is the Bela Vista Biological Refuge (RBV) in Foz do Iguaçu. Established in 1984, its initial purpose was to shelter wild animals rescued from the reservoir area—where land habitat was lost—and to serve as a nursery for forest seedlings used to create the Binational's approximately 34,000 hectares of protected areas.

To adapt the refuge's spaces to current needs and demands, including the use of zoo design strategies and ex-situ conservation actions, Itaipu Binacional organized a two-stage architectural competition open to architects from all over Brazil. Below is the winning proposal by RibasMarçal Arquitetura and Tempo Arquitetos.

Rammed earth is one of the oldest methods of constructing walls and still holds great potential for modern earth construction. One aspect of this potential is the gift of its colors and layers, which become visible as the formworks are removed, revealing a layered character. As a process that involves the layer-by-layer compression of gravel, sand, silt, and clay, its resulting appearance is a horizontal stratification of earth tones, material content, and curing procedures. This colorful appearance of rammed earth walls can be controlled and explored through patterns, texture, pigmentation, and natural clay colors, offering an opportunity to push its boundaries within architecture.
