Geothermal Haven Crafted with Spiraling Wooden Panels

Project in-detail

Rising from the rugged volcanic landscape, this geothermal haven features spiraling wooden panels and an inner courtyard that seamlessly connect visitors with the natural surroundings while serving as a refuge for exploration.
5 key facts about this project
01
Geothermal energy is harnessed from nearby thermal springs for heating and hot water.
02
Wooden panels rise from three to eight meters, creating a dynamic vertical experience.
03
The design includes an inner courtyard that enhances visitor interaction and comfort.
04
A narrow path leads visitors directly to the cave entrance, inviting exploration.
05
The project integrates with the geological landscape, emphasizing its tectonic context.

Grjótagjá's Crown is situated in a rugged volcanic landscape that lies between the Eurasian and North American tectonic plates. It serves as a refuge for visitors exploring this dramatic environment. The design concept emphasizes a strong connection between the built structure and the natural setting, showcasing a crown-like form that integrates with the surrounding terrain.

Design Concept

The central idea behind Grjótagjá's Crown is to create an inviting space that reflects its geological context. A narrow path guides visitors toward the entrance, leading them through the barren landscape. Upon arrival, they encounter a sheltering structure that connects them to the land. The wooden panels spiral upward, inspired by the local geological features, and create an experiential journey that encourages exploration.

Material Application

Wooden panels play a significant role in the project, rising from three meters to eight meters in height. This vertical progression provides both a sense of scale and a visual connection to the environment. Concrete walls complement the wooden elements, providing structural support while aligning with the overall design theme. This combination of materials fosters a relationship between the building and its surroundings, inviting nature into the experience.

Spatial Experience

The layout includes a lower space that functions as a gathering area for visitors. This space offers comfort and a place to prepare for further exploration. An inner courtyard is part of this design, providing shelter and facilitating social interactions. Within this courtyard is the cave entrance, which draws attention and invites visitors to explore the nearby geothermal springs, enhancing their connection with the landscape.

Sustainability Considerations

Sustainability is an important aspect of Grjótagjá's Crown. The nearby thermal springs provide geothermal energy for heating and hot water, making the building environmentally friendly. By using local resources, the design promotes a balance between built and natural environments. The thoughtful application of materials and energy solutions highlights the importance of sustainable practices in architecture.

The final aspect of the design emphasizes the relationship between the wooden panels and concrete walls. This interplay creates a fluid transition between inside and outside, allowing light to filter into the spaces and framing views of the dramatic volcanic landscape outside.
