The architecture of Latin America and Spain is testament to the rich and diverse cultures, traditions, needs, and solutions that define these territories. With more than 700 projects built in Spanish-speaking countries published on ArchDaily en Español, the time has come to explore, debate, and choose your favorites for the Obra del Año 2026 award.
In temperate and cold climates, architecture typically begins with a defensive gesture. The building envelope is a sealed boundary designed to resist the exterior environment through insulation, vapor barriers, and mechanical control. In cold countries like Canada, where winter temperatures can plunge well below freezing, airtightness is not a luxury. In this context, buildings must resist the exterior environment entirely to maintain interior comfort. However, in Central America, a region spanning from Belize to Panama, architectural logic shifts from exclusion to negotiation. In this region, the envelope is not a wall of defense but a specialized filter.
Historic center renewal has become a recurring strategy in Central American cities seeking to reassert the symbolic, economic, and functional relevance of their traditional cores. These processes often combine physical rehabilitation, institutional investment, and stricter control over public space. San Salvador offers a recent and instructive case, which allows for understanding of how interventions in inherited civic spaces balance infrastructure improvement with heritage conservation and social regulation. It also enables the assessment of how these choices resonate within broader debates on urban transformation in the region.
Held in Pamplona from the 23rd to the 26th of September, the 2025 Latin American Architecture Biennial (BAL) brought together emerging studios and established voices from across the continent. This year’s edition stood out for the diversity and depth of its participants: projects of striking formal and conceptual richness, developed by young yet remarkably mature offices. Together, they reflected the vitality of today’s Latin American architecture — thoughtful, inventive, and deeply aware of its context.
Ciudad Cayalá, a privately developed, mixed-use community on the outskirts of Guatemala City, is often described as a "theme park" of white lime-washed walls, red tiles, and cobbled plazas. A closer examination, however, reveals a more complex urban narrative. Its significance, however, lies in its capacity to create a safe and well-managed public space, proposing a modern reinterpretation of historic urban principles that mark the region's architectural and urban heritage. Behind the Antigua-style façades lies an urban experiment: a modern re-engagement with architectural elements like arcades, courtyards, and open plazas, which propose a privately-managed public space as a solution to urban challenges in the region.
Founded in 2002, Solis Colomer Arquitectos has established a strong reputation over the past two decades, designing and constructing projects with both social and commercial impact across Latin America. With over 200 completed works, the firm specializes in institutional architecture with social impact and user-centered commercial architecture. Its mission is clear: to use architecture as a tool to dignify the human experience, especially for those in greatest need.
Understanding the temperature gradient in a building is essential in cold or temperate climates, where airtight enclosures and continuous insulation are used to prevent heat loss. However, this approach is not suitable for tropical areas like Central America, where the climate is marked by a consistent alternation between wet and dry seasons rather than four distinct ones. Factors such as proximity to the sea, elevation, and local topography influence microclimates across short distances, but high humidity remains a common challenge. Sealed, airtight walls with no ventilation can quickly become breeding grounds for mold, making the thermal strategies of temperate climates problematic. In response, local designers have developed alternative approaches that embrace, rather than resist, the outdoor environment, allowing airflow and evaporation to manage interior comfort.
Once seen as purely utilitarian, bare concrete blocks have increasingly become part of an architectural transformation. In regions where warm climates make insulation unnecessary, this material can be left exposed, free of cladding, finishes, or embellishment. In doing so, texture, bond, and form can define the building's character and simplify construction while creating new opportunities for expression and identity. This also creates a platform to explore the concept of material honesty. Beyond its aesthetic value, using a material "as is" can significantly reduce construction costs and minimize maintenance during the building's lifespan.
The Latin American Architecture Biennial (BAL), which has gained significant relevance in the contemporary architectural scene, will celebrate its ninth edition next year. This meeting gathers emerging Latin American architecture studios in Pamplona, Spain, to share their work, fostering dialogue and debate about the current state of the discipline, as well as acting as a bridge between the Latin American continent and the Spanish context. In this edition, Costa Rica will be the guest country, accompanied by Honduras, El Salvador, Panama, Guatemala, and Nicaragua. As part of this invitation, there will be an exhibition and specific seminars dedicated to analyzing the situation of architecture in these countries.
A look at most of the cities within Latin America reveals striking commonalities across countries, from Mexico down to Argentina: most cities have a well-defined area known as "El Centro" (The Center), anchored by a main plaza (Plaza Mayor), flanked by a church on one side and key buildings like the city hall on another. This is no coincidence, as it can be traced back to an urban planning system established during the Spanish colonization of the Americas in the 17th and 18th centuries. It gave standardized guidelines for city design across its viceroyalties. Unlike French and English colonies, Spanish settlements adhered to regulations that contributed to the emergence of a shared urban identity, with cities displaying similar spatial logic and architectural cohesion despite differing scales and contexts.
