Integration of Local Aggregates and Reinforced Concrete in a Warm Visitor Center Experience

Project in-detail

Utilizing local aggregates and a reinforced concrete shell, the visitor center offers a warm, immersive experience that encourages connection with the surrounding volcanic landscape while prioritizing environmental integration.
5 key facts about this project
01
Utilizes existing volcanic soil and ash for structural integration.
02
Features an inclined roof that enhances landscape framing.
03
Reflective windows designed to blend with the surroundings.
04
Emphasizes energy efficiency through triple-glazed glass.
05
Incorporates outdoor terraces made from local aggregates.

The design is set within a volcanic landscape, where the main goal is to create a building that fits naturally into its environment. By using soil and ash from the site, the approach aims for a structure that blends in and feels part of the scenery. Visitors can have a rich experience connecting with the unique geological features of the area while enjoying the functional aspects of the building.

Conceptual Framework

The concept focuses on simplicity and respect for the landscape, highlighting the shape of the volcano. The exterior is designed to have a low profile, featuring reflective windows that connect visually with the surroundings. The building is oriented to be visible from the road, yet offers breathtaking views of the volcano. The angled roof invites visitors to engage with the environment more closely, enhancing their overall experience.

Structural Design

A reinforced concrete shell makes up the main structural support of the building, ensuring stability while accommodating the natural hillside. This solid construction minimizes visual distractions and eliminates the need for additional interior supports. Outdoor terraces made with local materials extend the building's connection to the site, reinforcing a commitment to sustainability.

Interior Experience

Inside, the space invites warmth and comfort, resembling the feeling of molten lava. This lively atmosphere provides a sharp contrast to the understated exterior. It is designed to connect emotionally with visitors, making their time spent within the space more enjoyable. The layout allows for various activities, offering flexibility and encouraging interaction.

The design also features local soil for insulation and triple-glazed windows that enhance energy efficiency while keeping maintenance low. Together, these materials create a blend of comfort and sustainability. The architecture maintains a visual and functional connection to the surrounding landscape, culminating in a design that feels both modern and rooted in its natural environment.
