Weathered Steel Structure Integrating Geothermal Energy in Volcanic Landscape

Project in-detail

Constructed with weathered steel and designed to harness geothermal energy, this facility harmonizes with the volcanic landscape while providing a multifunctional space for public engagement and exploration.
5 key facts about this project
01
Constructed primarily from weathered steel, ensuring durability in harsh climatic conditions.
02
Integrated geothermal energy system for sustainable heating and cooling.
03
Includes observation areas that enhance visitor interaction with the surrounding landscape.
04
Designed to mimic the natural landscape’s topography through a bent A-frame structure.
05
Utilizes rainwater collection systems, promoting environmental sustainability.
The Breaktower project is an architectural intervention located in Grjótagjá, Iceland, conceived to engage with the unique geological context of the area, characterized by tectonic movements resulting from the North American and Eurasian plates. This project aims to serve both as an exploration facility and a landmark, integrating the built environment with the rugged natural landscape. Its design embodies functionality, sustainability, and a deep respect for the surrounding topography.

Materially, the Breaktower is constructed primarily from weathered steel, ensuring durability in the harsh Icelandic climate while allowing the structure to visually and conceptually resonate with the natural environment. The use of concrete foundations provides stability, supporting upper levels reinforced with steel and further enhancing the project’s resilience. Additionally, glass elements are used strategically to provide natural light and panoramic views of the stunning volcanic scenery, allowing visitors to connect directly with their surroundings.

Unique Interactions with the Landscape

What sets the Breaktower apart from conventional architectural projects is its emphasis on spatial connectivity and the visitor experience. Paths are carefully designed to encourage exploration and interaction with the landscape, enhancing social engagement among visitors. Different volumes of the structure create distinct spatial experiences, seamlessly transitioning from public to more intimate areas, allowing for both shared and personal moments in the setting. The integration of lookouts and thermal spas invites users to pause and engage meaningfully with the natural environment.

The architectural design responds intuitively to the surrounding geological features. The symmetrical organization of the structure, along with its dynamic silhouette, reflects the balance between the tectonic forces that shaped the landscape and the human desire to inhabit it. The synthesis of form and function is evident through the careful articulation of massing, which allows the structure to maintain a slender profile that adapts to the undulating land.

Sustainable Architectural Practices

Sustainability is a core principle driving the project’s design. The Breaktower utilizes geothermal energy for heating and incorporates rainwater collection systems, demonstrating a commitment to reducing ecological impact while enhancing user experience. The material choices not only align with aesthetic goals but also prioritize environmental accountability, showcasing how architecture can harmonize with the ecological context.

The Breaktower project represents a sophisticated intersection of architecture and nature, allowing visitors to engage with the dynamic Icelandic landscape while providing a functional, sustainable space. To fully appreciate the nuances of the architectural plans, sections, designs, and innovative ideas brought forth in this project, readers are encouraged to explore the detailed presentation further.

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.
