This year's selection of Best Latin American Houses brings together both renovations and ground-up projects, covering reinterpretations of local construction techniques and innovative architectural responses. The works are set in a wide range of contexts, from dense urban environments to rural and coastal landscapes.
As the year culminates, it's once again time for the ArchDaily team of curators to reflect on the best-performing projects of 2025 and consider what readers were most interested in. Through this diverse overview, we assess the cross-continental similarities and differences in trends and construction development. This year brought us many grand cultural and public spaces by Lina Ghotmeh, BIG, Zaha Hadid Architects, DnA, and Serie Architects, who populated events like Expo Osaka and the Venice Biennale, as well as a surprising number of museums and public or landscape works in China and the rest of the Asian continent. However, while these were sought-after projects, the leading works remained, unsurprisingly, residential projects.
More specifically, the houses that were most viewed on the ArchDaily global site were concrete houses that bore considerable injections of greenery and landscape focus. They propose layouts highlighting voids and double heights, as well as inner courtyards or large openings to the exterior. While some references did suggest traditional or vernacular elements, modernist revivals were still predominant. Material trends are much more tame, with a recurrence of raw concrete use, as wood and stone were common accent elements. Still, the more interesting thing about the works this year is the efforts brought by architects in situating and setting the projects within their surroundings, bringing special attention to landscape and how projects merged with nature.
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.

We walk on "flat" ground every day and rarely think twice—but how flat is it, really? In the city, curbs are chamfered, sidewalks pitch toward grates, and roadways are crowned to shed water into shallow gutters. In suburbs and on unpaved paths, irregular terrain is the norm. Inside buildings, by contrast, we pursue near-perfect horizontality—structural frames, slabs, and finishes are all disciplined to create level walking surfaces in the name of safety and accessibility. Yet flatness is inherently at odds with water. A closer look reveals a quiet repertoire of accommodations: slight falls at entries, thresholds raised a few millimeters, wet areas with barely perceptible pitches. The floor is read as flat, but it is in fact carefully tuned—micro-topographies masquerading as plane—to manage water without calling attention to themselves.
What are the common ways architects "keep things flat" while actually managing water—the perennial enemy of buildings? A useful way to look at it is by zooming into three recurring conditions: exterior or roof decking, bathrooms and other wet rooms, and exterior ground planes. Each relies on a slightly different toolkit—pedestal systems over sloped waterproofing, micro-gradients to floor traps, hidden perimeter drains, split slopes—to maintain the illusion of a seamless, level surface. Studying these situations side by side reveals just how much design effort goes into reconciling perceptual flatness with the messy reality.
