Over the last two weeks, the ArchDaily en Español community submitted more than 17,000 nominations, yielding 15 finalists that represent some of the most emblematic architectural works of the past year. Decided by its community, the 2026 Building of the Year Award—the most significant architecture prize in the Spanish-speaking world—exists to recognize the best of architecture across Spanish-speaking countries.

These 15 finalists, chosen by public vote in this 17th edition, showcase the breadth of recent Ibero-American production while highlighting shared shifts in contemporary practice: an architecture that prioritizes clear construction choices, operates within real-world constraints, and understands design as a way of adapting to specific contexts.

From May 20 to 21, 2023, the Open House architecture and urbanism festival will take place in the city of Rosario, opening the doors of 98 architectural works alongside 8 urban tours to discover and rediscover the city's architecture and urban design. For its sixth edition, this year's festival aims to venture deep into the heart of the city—the home—applying an urban approach committed to the individual and collective memory of the city and its residents, merging tangible built heritage with the traces of time.

Year after year, organizations, government authorities, and other global entities face the challenge of implementing regulations and measures to address rising water scarcity: as of 2017, according to the World Health Organization, roughly 3 out of 10 people lacked access to safe drinking water at home, while 6 out of 10 lacked access to safely managed sanitation.

Trees are often the first things to vanish when construction starts. Clearing a site has long been one of architecture's most immediate acts, removing what already exists to make room for something new. When vegetation is preserved, it is typically treated as a secondary layer, added back as landscape rather than shaping the project itself.

However, some projects begin elsewhere. Instead of starting from a blank site, they work with what is already there. Trees remain in place, not as elements to frame, but as conditions that influence how space is organized, how light enters, and how architecture takes form.

Theaters serve as cultural and social institutions, shaping society by providing spaces where stories of identity, race, and justice are brought to life. These venues foster community through shared, live experiences, sparking conversations that resonate beyond the stage. Architecturally, theaters are more than performance spaces—they are landmarks that embody both the history and future of the arts. Their design often reflects the cultural importance of storytelling, while their refurbishments ensure they remain relevant in a modern context.

In this week's AD Interior Focus, ArchDaily explores how the refurbishment of iconic theaters like the Royal Opera House in London, United Kingdom, and Sydney Opera House in Australia goes beyond modernizing comfort and accessibility. It delves into how these projects preserve the architectural integrity of these historic landmarks, ensuring their design continues to serve as a backdrop for both artistic expression and social discourse.

Modernism played an undeniable role in the renewal of architectural ideals, contributing a new attitude toward understanding new ways of living, construction techniques, and aesthetics, marking profound changes in the general perception of the world. In Argentina, while it is complex to define modern architectural production periodically, it is possible to mention some architects who began, starting in the 1920s, to engage with these ideas. The intellectual contributions and architectural creations of Alejandro Virasoro, Alberto Prebisch, Ernesto Vautier, Fermín Beretervide, Wladimiro Acosta, Alejo Martinez, Antonio and Carlos Vilar, Juan Kurchan, Jorge Ferrari Hardoy, Antonio Bonet, Abel López Chas, Eduardo Catalano, Eduardo Sacriste, and Amancio Williams, among others, often included original approaches associated with new modes of thought, manifesting an architecture resulting from the analysis of the local and regional conditions of their cities.

Bathrooms play a significant role in our daily lives, serving multiple functions beyond basic hygiene. Research highlights their importance as relaxation, introspection, and personal wellness spaces. A bathroom's design and comfort can profoundly influence how we begin and end our day, framing our routines with a sense of ease or disruption. When traveling, hotel bathrooms often leave a lasting impression, as a well-designed and thoughtfully executed bathroom can significantly elevate the overall experience of a stay.

Nowadays bicycles are not only used for sports or as a recreational activity, as more and more people are choosing bicycles as their main means of transportation. Architecture plays a fundamental role in promoting the use of bicycles, as a properly equipped city with safe bicycle lanes, plentiful bicycle parking spots, and open areas to ride freely will encourage people to use their cars much less.

Cities are now positioning themselves as a key promoter of sustainable mobility, and Denmark and the Netherlands are currently the leading countries in the field of architecture for bikes. They are considered a cyclist's paradise because of their excellent infrastructure and architecture, making them a worldwide reference.
