Costa Rican Architecture

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.

Costa Rica is a small country in Central America, internationally renowned for its tourism, biodiversity, and tropical climate. Given this context, tropical design strategies for hotel design are often more studied, but residential cabin projects can represent a more surgical approach to understanding the landscape. Often situated in remote forest or jungle locations, these cabins, apart from the common tropical design strategies, have to prioritize long-term durability and low-maintenance costs, particularly in regions where access for repairs is logistically difficult. This necessitates a design philosophy that favors both structural and climatic resilience.

In the coastal and jungle regions of Costa Rica, high humidity and intense solar radiation dictate an architectural strategy centered on permeability rather than enclosure. Unlike the airtight envelopes required in cold climates to retain heat, Costa Rican architecture uses the building envelope as a climatic filter to maximize air exchange. The primary mechanism for managing these thermal gradients seems to be the oversized roof overhang. By extending the roof plane significantly beyond the floor plate, architects create a permanent buffer of deep shade that reduces solar gain and lowers the ambient temperature before air enters the structure. This strategy, combined with permeable or non-existent walls, allows for constant airflow. This is a critical technical requirement for humidity control and the prevention of material degradation through mold and rot.

The conversation with VOID emerges within the framework of the 2025 Latin American Architecture Biennial, offering an opportunity to explore a practice that listens, cares, and accompanies. Their work unfolds as an act of mediation: through interdisciplinary research and attention to the plurality of natural and social factors, they seek to understand the many natures of a place. Since its beginning in 2012, this process has evolved, consolidating a stance that seeks to design architecture from and for the place—caring for it, healing it, and regenerating it—opening spaces where territories sustain and unfold their own adaptive processes.

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.

Thatching is a traditional building technique that has been reinterpreted in different ways in contemporary projects, allowing its value to continue to endure over time. As well as being a culturally and historically valuable technique, given its presence in humanity for centuries, it also has a number of other constructive advantages, such as its great environmental value, as it is an accessible renewable material.

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.

Many people living in large urban centers have, at some point, wished to trade the chaos of city life for the calm and tranquility of nature. As the desire for such experiences grows, Latin American countries' tourism and hospitality sectors have been investing in resorts nestled within forests. Inspired by eco-tourism, these retreats are designed to blend seamlessly into their surroundings, using local materials and traditional techniques that respect the ecosystem and promote sustainability.

Annually, ArchDaily's curatorial team undertakes a rigorous selection process to identify exemplary projects in Latin American residential architecture. The goal is to share these works of architecture with our audience and highlight and promote good practices within contemporary architecture. This meticulous effort focuses on identifying projects that stand out for their design and their positive impact on the environment, innovative use of materials and techniques, and ability to address current needs.
