Volcanic Rock and Ferronconcrete Structure Uniting Geothermal Energy with Visitor Engagement

Project in-detail

Constructed with volcanic rock and ferronconcrete, this visitor center harnesses geothermal energy to create a functional space that enhances engagement with Iceland's unique geological landscape.
5 key facts about this project
01
Constructed with locally sourced volcanic rock to blend seamlessly with the landscape.
02
Incorporates ferronconcrete for structural durability and thermal mass.
03
Utilizes geothermal energy for heating, minimizing environmental impact.
04
Features a unique observation tower for panoramic views of the surrounding terrain.
05
Design promotes natural light flow through large windows and open spaces.
The Rising Hollow project is located in the vicinity of Myvatn Lake in Iceland, an area distinguished by its volcanic landscape and geothermal features. This architectural design serves as a visitor center and observatory tower, facilitating interaction with the local environment. The project integrates with the surrounding geological characteristics, emphasizing sustainability and energy efficiency through the use of local materials and innovative design strategies.

The primary function of the project is to provide amenities for tourists exploring the unique landscape of the area, while simultaneously acting as an educational platform focusing on the region's geological heritage. The design includes essential spaces such as an exhibition area, a café, and observation points that enhance the visitor experience.

The visitor center’s layout supports a natural flow of movement, guiding visitors from the parking area through a pathway leading to the main entrance. Key components of the design include a prominent observation tower that offers panoramic views of the surrounding landscape, a spiral staircase that connects different levels, and large windows that maximize natural light. The materials selected for the project—volcanic rock, ferronconcrete, larch wood, extruded polystyrene, and shotcrete—are prominent throughout the structure, reinforcing its connection to the site.

One distinguishing aspect of the Rising Hollow project is its response to the local climate and geological conditions. The design capitalizes on geothermal energy for heating, ensuring a reduced environmental footprint. Additionally, the use of volcanic rock aligns the structure visually and contextually with its setting, serving both aesthetic and functional purposes. The integration of exterior and interior spaces allows for various perspectives of the landscape, while the exploration of textures through material choice adds to the architectural narrative.

The incorporation of energy-efficient geothermal systems and local materials not only reduces operating costs but also promotes environmental stewardship. The organization of the visitor routes, alongside distinct zones for learning and observation, enhances the interaction between visitors and the natural features of the site.

For further insight into the Rising Hollow project, including architectural plans, architectural sections, and architectural designs, readers are encouraged to explore the detailed project presentation that elaborates on the innovative architectural ideas that define this unique intervention in Iceland's landscape.

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.
