Crystalline Structures Embracing Geothermal Energy in Iceland's Wilderness

Project in-detail

Emerging from the Icelandic landscape, crystalline forms house geothermal energy systems, creating a visitor center that seamlessly integrates intimate bathing experiences with the region's natural and cultural heritage.
5 key facts about this project
01
Crystalline structures mimic natural ice formations in the landscape.
02
Geothermal energy systems provide sustainable heating and bathing.
03
Visitor center integrates with both public and private cave spaces.
04
Illumination design minimizes artificial light, highlighting natural phenomena.
05
Paths are designed with permeable materials to protect the terrain.

The Ginnungagap SAGA project is located in northern Iceland, around 70 km from Akureyri, in a landscape rich with geological history and cultural significance. The design captures the meeting of elemental forces—frost and heat—inspired by the region’s ancient myths. As a visitor center, it serves to connect guests with the natural environment while introducing them to the unique characteristics of Icelandic wilderness.

Site Context and Conceptual Framework

The project draws upon the ancient rift of Ginnungagap, representing a space where creation occurs. Crystalline forms rise from the land, echoing the area's geological history. The structure encourages exploration, inviting visitors to experience the narratives that the land holds. There is a clear connection between the architecture and the surrounding environment, enhancing the understanding of Iceland's past.

Visitor Experience and Functional Zoning

The design divides into distinct public and private areas, creating different experiences for visitors. The public section includes the Karlagja entrance, marked by an observatory that offers broad views of the landscape. This area hosts an exhibition space highlighting geothermal energy, showcasing the natural resources available in the region. Smaller buildings accommodate visitor services, including a café and restrooms, ensuring comfort and accessibility.

Private Spaces and Personal Engagement

The Kvennagja cave provides opportunities for a more personal experience. Visitors can reserve times for bathing in private settings. The design includes areas for waiting and changing, enhancing comfort while respecting the cave's natural form. This focus on individual interaction encourages visitors to connect with the environment in a meaningful way.

Sustainable Design Strategies

Choosing materials and employing environmental strategies are essential in this design. The project features a curtain wall similar to those used in traditional Icelandic greenhouses, while private areas include an inner concrete layer that maximizes thermal efficiency. A binary electric generator captures geothermal energy, providing heat for bathing and other uses. Paths are created with granulated sand and permeable concrete to minimize disruption to the land while ensuring strength against frost damage.

Light and texture play a significant role in the overall design. Natural light is prioritized, reducing the need for artificial illumination throughout the site. The crystal-like structures glow softly at night, enhancing the connection between the built environment and the natural wonders that surround it.

`
Competition organisers

The MICROHOME 10 competition invites participants to submit visionary designs for off-grid, modular microhomes that push the limits of sustainable, small-scale living. Organised by Buildner in partnership with Kingspan and Hapi Homes, this tenth edition sets the challenge of designing a dwelling for two people within a maximum floor area of 25 m², encouraging bold solutions adaptable to any urban or rural location. The competition continues Buildner’s mission to foster innovative approaches to compact, energy-efficient housing that can address pressing global challenges.

This year’s edition offers a generous total prize fund of €100,000, including the Kingspan Award for designs that integrate high-performance Kingspan products and the Hapi Homes Award for a project selected for real-world construction. In addition to cash prizes, the winners gain international exposure through Buildner’s media partnerships, publications, and a dedicated MICROHOME magazine, further amplifying their ideas to the wider architectural community.

Key dates for MICROHOME 10 include the closing date for registration on 25 September 2025, the submission deadline on 29 October 2025 (11:59 p.m. London time), and the announcement of winners on 9 December 2025. These milestones ensure participants have clear timelines to develop and present their concepts, with early registration discounts available to support students and emerging designers worldwide.
