Architects carefully calibrate their relationship to the earth, adjusting foundations to soil, groundwater, climate, risk, and culture. Driven timber piles, rammed-earth platforms, and poured concrete slabs are each a response to a specific set of ground conditions, and each shapes the architecture that rises from it. The way a building meets the earth determines its durability and its limits because foundations are among the most consequential design choices an architect makes.
The city of Rotterdam sits approximately one meter below sea level, an organizing condition that shapes daily life in the Netherlands' second-largest city and is a growing preoccupation amid unstable coastal conditions. The city occupies the delta of the Rhine and Maas rivers, a landscape that was never naturally dry but has been kept functional through centuries of hydraulic intervention. The water boards in this region are among the oldest democratic institutions in the world, created in the thirteenth century to manage shared water drainage and still operating today as elected bodies with technical capacity. As sea levels rise and rainfall across Northern Europe grows less predictable and more extreme, Rotterdam faces a significantly increased risk of coastal storm surges and urban flooding driven by overwhelmed drainage infrastructure.

Two weeks and over 85,000 nominations later, the finalists of this year's Building of the Year Awards are in. The selection is much like the ArchDaily audience that chose it: diverse in geography, generous in ideas, and precise in intent. With projects from 46 countries, in a variety of typologies and scales, they present a beautiful snapshot of the current architectural moment.
We invite you to sit back, browse, and vote for your ultimate favorites. Below, you will find all of the 75 finalists in their respective categories. Voting is open until February 18th at 18:00 EST. Thank you—your participation is key to making this the world's largest community-driven architecture award.

As the solstice marks the shortest day of the year in the Northern Hemisphere, it also draws attention to something architecture has long negotiated but often overlooked: time. Beyond form or function, buildings and spaces are continuously shaped by cycles of light and darkness, seasonal shifts, and environmental rhythms that affect how they are inhabited.
In recent years, a growing number of architectural projects have begun to work explicitly with these cycles. Rather than designing spaces to function in a single, fixed way, architects are creating environments that change throughout the day, across seasons, or in response to natural phenomena such as the sun's path, lunar phases, wind patterns, or circadian rhythms. These projects operate in dialogue with time, appearing, transforming, and activating differently depending on environmental conditions.

As 2025 approaches its end, we look back at an eventful year in the world of interior design. Last year, designers favored reserved, modest approaches, a trend that continued from previous years. The emergence of artificial intelligence generated intense discussions on digital equity and misinformation, which continued into 2025, especially with the topic of the Venice Architecture Biennale, Intelligens. This opened the conversation to the opportunities of digital technologies, attempting a more hopeful outlook. On the other hand, completed interior design projects over the year focused more on the tangible and the pragmatic, with expressed raw materials and an appreciation of history.


How do pavilions emerge in architecture? What role do they play in urban spaces? Beyond the multiple interpretations that exist around the world, the pavilion, as an architectural principle and typology, tends toward extroversion, often associated with a centrifugal nature and visual openness toward the horizon, which is linked to its origins as a tent offering shelter from the elements. Pavilions are usually identified as isolated and independent structures that can promote lateral openings in the urban space, panoramic or introspective views, technological reflections, and material experiments that are recognizable from the outside or once inside.
