GUÁRUMO / Topography as Architectural Order
In the Guarumo project, the relationship between architecture and terrain begins with a fundamental premise: the slope should not be corrected—it should be understood. In tropical contexts, where soil, water, and vegetation function as interconnected living systems, regenerative architecture proposes a different approach to hillside construction.
Rather than imposing a form onto the terrain, Guarumo develops an architectural strategy that moves with the topography. The project is organized through a series of stepped volumes that follow the natural contours of the site. In this way, each level establishes a distinct relationship with its surrounding environment.
From the moment of arrival, the architecture does not present itself as a single dominant volume conquering the mountain. Instead, it unfolds as a sequence of planes that settle naturally along the slope. Views gradually open up, allowing each space to establish its own dialogue with the landscape.
At the same time, natural ventilation follows the direction of the terrain. Air flows freely between volumes, while existing vegetation becomes progressively integrated into the project. In this sense, sustainable architecture is not limited to energy efficiency; it begins with the way the building touches the ground.
Light also transforms as one moves down the hillside. In the morning, sunlight filters laterally across inclined surfaces; in the afternoon, shadows stretch along the natural descent of the terrain. Even the sound of rainfall on the slope becomes part of the spatial experience rather than a structural concern.
Here, regenerative architecture demonstrates how technical coherence can translate into a deeply human and natural spatial experience.
Urban growth has increasingly expanded into areas with moderate and steep slopes around the world. According to UN-Habitat, more than 30% of urban development in tropical and subtropical regions now occurs in topographically complex environments.
However, the way hillside construction is commonly approached rarely responds to a deep reading of the site.
In many cases, the slope is interpreted as an obstacle that must be corrected. Large portions of terrain are cut, natural depressions are filled, and massive retaining walls are built as immediate structural solutions.
This approach generates cumulative impacts such as:
In climates such as Costa Rica’s, where annual rainfall can exceed 2,500 mm, these issues become even more pronounced. Soil saturation increases, geotechnical stability becomes more fragile, and architecture ends up relying on expensive structural solutions to solve a problem that could have been avoided during the site implantation phase.
Regenerative architecture invites us to ask a different question:
When Topography Organizes Architecture
In the Guarumo project, the design does not reshape the terrain to accommodate the architecture. Instead, it begins with a precise reading of the existing topography guided by a clear principle: the slope is interpreted rather than corrected.
This is a technical, environmental, and ethical decision. The greater the adaptation of a project to the natural terrain, the lower the long-term structural and environmental impact.
From the perspective of regenerative architecture, the soil is not an inert surface but a living system that must remain functional.
Guarumo organizes its program through a stepped volumetric strategy that follows the natural levels of the site. Each volume rests where the terrain allows it, reducing excavation and avoiding large artificial fills.
The result is an efficient construction strategy combined with an architecture that appears to accompany the hillside—as if it had always been there.
The stepped volumes of Guarumo are not an aesthetic gesture but a construction strategy designed to control the project’s physical impact on the terrain.
Various sustainability studies on hillside planning show that reducing earth movement can lower soil stabilization and retaining costs by approximately 25–35%.
Projects that avoid large retaining walls also tend to present lower risks related to hydrostatic pressure, particularly in regions with heavy rainfall.
Costa Rica presents a particularly delicate combination:
These conditions demand that sustainable architecture on slopes be approached with special care.
In Guarumo, volumetric stepping allows the project to:
From a regenerative design perspective, the landscape possesses its own internal logic.
Therefore, the objective is not to dominate the terrain, but to establish a dialogue with it.
Topography not only affects structural stability—it also regulates local climate conditions.
In tropical hillsides, air circulation follows natural thermal gradients: warm air rises while cooler air descends.
The stepped configuration of Guarumo’s volumes allows the project to take advantage of this phenomenon, creating natural cross ventilation between levels.
Each volume captures air currents differently, while the shade cast by one level helps protect the next from excessive solar exposure. The slope itself assists in dissipating accumulated heat.
In this sense, regenerative architecture does not rely exclusively on technological efficiency. It also draws from a deep understanding of natural environmental conditions.
Understanding microclimate allows sustainable architecture to work with nature rather than against it.
Before discussing materials or technologies, the way architecture is placed on the land defines its real impact.
Deciding how a building touches the terrain is ultimately an ethical position.
In Guarumo, topography is not seen as a constraint to overcome but as the system that organizes the project.
This position aligns with the principles of regenerative architecture, where the objective goes beyond simply reducing negative impact—as traditional sustainable architecture often proposes.
Regenerative design seeks something deeper: conscious integration with existing natural systems.
From this perspective, the soil is understood as a complex organism. Aggressively altering it generates cumulative consequences over time.
Respecting it means acknowledging that architecture forms part of a broader territorial balance.
Guarumo proposes a form of hillside construction that does not seek to dominate the slope, but to understand it.
At Guarumo, materiality is a direct response to a demanding climate. The challenge is ensuring that the materials integrated into the project can withstand the many conditions present on site: sun exposure, rain, humidity, salinity, and more.
For this reason, the design team chose to work with materials for which aging over time becomes an advantage. They develop a patina, express temporality, and become increasingly rooted in their context each day.
As a result, the passing of time does not necessarily imply constant repairs, restoration, or excessive maintenance. Instead, the project becomes more sustainable in the long term.
Board-formed concrete gives texture and character to the overall composition, becoming part of the architectural narrative and helping to tell a story.
The thermal mass of concrete protects the project from direct sunlight and heat. Interior spaces remain cool and comfortable, helping reduce the need for air conditioning.
Corten steel introduces warmth and a distinct accent to the space.
In summary, materiality is not a decorative decision—it is a strategy born from a deep reading of the site.
Designing for sloped terrain cannot rely on generic solutions. It requires careful observation, technical judgment, and contextual sensitivity.
Sustainability studies play a fundamental role in this process by providing insights into soil behavior, drainage patterns, and climatic conditions.
The Guarumo project demonstrates that:
In tropical territories where climate and topography interact intensely, regenerative architecture becomes not only relevant but necessary.
Building on slopes involves decisions that directly affect soil stability, water movement, and climatic performance.
Guarumo shows that when topography becomes the organizing principle of design, architecture can integrate more coherently with the landscape.
Within this approach, sustainable architecture begins with implantation. Regenerative design expands that perspective by understanding the soil as a living system.
The project therefore does not impose form onto the landscape but builds a balanced relationship between architecture and territory.
Because terrain is frequently modified through aggressive cutting and filling processes that disrupt natural drainage systems and soil stability.
Guarumo organizes its architecture according to the existing topography, minimizing direct intervention and aligning with regenerative architecture principles.
Not necessarily. If a project does not respect the slope, even energy-efficient buildings can create structural and environmental issues.
They provide essential data about soil conditions, drainage patterns, and climate, allowing more responsible design decisions.
Regenerative design seeks to maintain the functionality of natural site systems. In tropical hillsides, this means minimizing intervention and allowing natural terrain processes to continue operating.
