The 15 Finalists of ArchDaily Brasil's 2026 Building of the Year Award

Subscriber Access | 

Over the past two weeks, the ArchDaily Brasil community has nominated more than 14,000 projects, resulting in 15 finalists representing some of the most iconic architectural works published over the last year. Now in its 10th edition, the Obra do Ano Award recognizes the best of architecture in Portuguese-speaking countries, chosen by the readers themselves. The finalists offer a snapshot of the current state of architecture, spanning residential, urban, cultural, and other programs.

Representing Brazil and Portugal, the 15 projects reflect the needs of their specific contexts through creative solutions proposed by local architects. From interior renovations to large-scale urban interventions, and from single-family homes to community projects, the selection is diverse, yet united by a common thread: recognition from the public, who seek to see their own aspirations represented.

How to Minimize Harmful Effects of Formaldehyde Gas Indoors

As people are spending more and more time inside their homes, offices, and other closed areas, it is important to ensure that these spaces are safe and healthy environments, especially indoor areas designed for children and seniors. In recent years, several of the materials that shape the spaces we inhabit and directly influence the quality of the air we breathe have increasingly used a potentially dangerous chemical compound. This compound is called formaldehyde.
