Underground Structure With ETFE Panels Integrating Natural Light In A Volcanic Landscape

Project in-detail

Crafted with ETFE panels and integrated into a volcanic landscape, the underground center enhances visitor interaction with geological history through natural light and engaging spaces for education and observation.
5 key facts about this project
01
Crafted primarily underground to blend with the volcanic landscape.
02
Utilizes ETFE panels for natural daylight without compromising insulation.
03
Features geothermal heating sourced from the surrounding volcanic ground.
04
Incorporates visitor engagement zones that frame views of the volcano.
05
Light wells enhance interior lighting while connecting spaces to the outdoors.
The Visitors Center project integrates architecture with its volcanic surroundings, functioning as a hub for education and exploration. Strategically located in an area rich in geological features, the center is designed to enhance visitor engagement while minimizing its impact on the landscape. By situating the majority of the structure underground, the design takes advantage of the natural terrain and offers a unique experience that highlights the volcanic context.

The architectural design emphasizes accessibility and flow, comprising key areas including a reception area, café, playroom, and information center. Entry points are thoughtfully placed to facilitate visitor movement from parking areas directly to significant attractions. The layout encourages exploration while providing essential information about the geological characteristics of the region.

Unique Design Approaches

One standout feature of this project is its reliance on sustainable materials, prominently including ETFE panels. These panels serve as an innovative roofing solution, allowing ample natural light while also ensuring thermal efficiency. The choice of concrete for foundational and structural elements contributes to the building’s durability, which is necessary given the geological conditions of the site.

Moreover, the incorporation of independent energy systems reflects a commitment to sustainability. The use of hydrogen for electric power generation and geothermal heating aligns with modern architectural trends prioritizing environmental responsibility. This aspect is particularly relevant in architecture that aims to harmonize with its surroundings.

Architectural Forms and Spatial Dynamics

The design also prioritizes interaction with the geological landscape through strategically placed vantage points. Visitors are guided to areas offering substantial views of the volcanic formations and lava fields, fostering a direct connection between the built environment and nature. Light wells integrated into the structure improve interior lighting and enhance spatial dynamics by creating varying experiences within the different functional spaces of the center.

This project stands apart from typical visitor centers through its profound integration with the terrain and its dedication to educating the public about the volcanic environment. By merging functionality, environmental consideration, and aesthetic sensitivity, the Visitors Center establishes a new paradigm for designing spaces that honor their natural context.

Design a new small-scale home concept in the 10th edition of MICROHOME — 100,000 € prize + construction

Competition organisers

The 10th edition of the MICROHOME architecture competition invites architects and designers from around the world to explore the possibilities of compact, sustainable living. Hosted by Buildner in collaboration with Kingspan and Hapi Homes, this special edition challenges participants to design an off-grid, modular microhome for a young professional couple, with a maximum floor area of 25 m². Designs should prioritize innovation, efficiency, and real-world feasibility. 

A total prize fund of 100,000 € will be awarded, including three main prizes, the Kingspan Award, and the Hapi Homes Award, which will grant 15,000 € and lead to the construction of the selected design. The final registration deadline is September 25, 2025, and winners will be announced on Decebmer 9, 2025. For full competition details and submission guidelines, visit microhome.info.
