Each year, the ArchDaily Curatorial team reviews the projects that resonated most with our readers, identifying the architectural trends and design approaches that captured the greatest attention throughout the year. Across our local sites – ArchDaily Brasil and ArchDaily en Español – residential architecture remains the most popular category, with projects built in Latin America standing out year after year.

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.

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.

Creating spaces for social interaction involves design processes aimed at countering the individualization of people by fostering bonds and connections between them. While advancements in information and communication technologies provide new tools that optimize the development of certain activities and functions, their societal impact often tends to increase individual practices, such as remote work, virtual fitness activities through apps, or the digital consumption of goods, services, and events, among others. From architecture and interior design to urban planning, many emerging practices face the challenge of consolidating spaces for social interaction through design strategies, uses, and natural connections that prevent the replacement of physical space with virtual alternatives.

The interior design of gastronomic premises is becoming increasingly important due to the demand for improvement in the areas of competition, customer experience, and brand identity. The ability to adapt to current trends and needs is a point that Argentinian architecture and interior design professionals have been facing with innovation and flexibility in the use of materials, colors, and textures.
