Volcanic Stone Structure Embracing Natural Light Through Geothermal Heating

Project in-detail

Constructed with locally sourced volcanic stone and integrated geothermal systems, this structure maximizes natural light while providing versatile communal spaces for visitors to experience the unique Icelandic landscape.
5 key facts about this project
01
Constructed with volcanic stones sourced directly from the site, enhancing ecological integration.
02
Features a steel mesh framework that allows for adaptable and dynamic aesthetics.
03
Utilizes geothermal heating, minimizing energy consumption and environmental impact.
04
Designed to maximize natural light with strategically placed openings throughout the structure.
05
Incorporates curved ramps that mirror the surrounding landscape, reinforcing harmony with nature.
The project "Rocks, Air, Almost Nothing" is an architectural design located in Iceland, a region characterized by its unique geological formations resulting from tectonic activities. This architecture integrates seamlessly with its landscape while offering functional spaces for visitors to engage with the environment. The design fundamentally seeks to create a dialogue between human experience and the natural world, using architectural forms that resonate with the surrounding volcanic context.

The main components of the project include a cave-like entrance, a multi-tiered observation tower, and an interconnected bridge. The cave embodies a welcoming threshold, inviting visitors into the space. Within, the design combines both exhibition areas and communal places, emphasizing the need for interaction among individuals. The tower provides elevated viewpoints of the surrounding terrain, enhancing the relationship between architecture and nature. The bridge facilitates movement across variations in elevation and structure, reinforcing accessibility while offering visual continuity across the site.

Unique Design Approaches

This design distinguishes itself through its organic integration of natural elements. The use of volcanic stones as both structural and aesthetic components ties the built environment to the geological identity of the site. These stones are anchored using a steel mesh framework, creating an interplay between rugged natural forms and refined engineering, all while maintaining a minimal ecological footprint.

A defining aspect of this project is its commitment to sustainability. The incorporation of a geothermal heating system reduces reliance on non-renewable energy sources, exemplifying a thoughtful approach towards environmental impact. Natural light is optimized through strategic openings, not only enhancing the internal atmosphere but also providing dynamic visual interactions with the surrounding landscape.

Exploring the sensory and experiential aspects of architecture, the project employs intentional spatial transitions which evoke a sense of movement and discovery. Visitors traverse the dark corridor that leads into well-lit communal spaces, reminiscent of venturing from a cave into openness. This design choice reflects principles of experiential architecture, bridging the gap between physical structures and lived experiences.

Material and Structural Considerations

The project utilizes a carefully selected palette of materials aligned with its geographical setting. The primary materials include volcanic stones, steel mesh, weathered wood, and concrete. Each of these elements serves not only to fulfill aesthetic objectives but also addresses structural integrity and functionality. Weathered wood, for example, contributes to a comfortable atmosphere within internal spaces, while concrete ensures lasting durability throughout the structure.

The architectural plans detail careful consideration of the relationship between interior and exterior environments, reinforcing a sense of continuity. Architectural sections illustrate the interplay of different levels and spaces, demonstrating a refined understanding of spatial organization that maximizes the visitor experience.

For those interested in a deeper understanding of this architectural project, exploring the architectural plans, architectural sections, and detailed architectural designs will provide further insights into the underlying concepts and methodologies employed in this thoughtful design solution.

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.
