Lava Rocks and Geothermal Heat Captured in a Multifunctional Space

Project in-detail

Built with locally sourced lava rocks and designed to leverage geothermal heat, the facility offers a multifunctional space for visitors to engage with the landscape while reflecting on the interplay between fire and ice.
5 key facts about this project
01
Utilizes geothermal heat to maintain a stable indoor climate.
02
Features a ventilation window designed to resemble a volcanic crater.
03
Incorporates locally sourced lava rocks for structural integrity.
04
Includes a dedicated meditation room for environmental reflection.
05
Offers direct views of Hverfjall Volcano from multiple areas.

The Glacier Cafe is located at the base of Hverfjall Volcano in Iceland, a site that captures the natural beauty characteristic of the country. It functions as a space for visitors to gather, enjoy refreshments, and engage with the stunning landscape. The design draws on themes of volcanic activity and glacial formations, aiming to create a dialogue between these two powerful forces of nature.

Architectural Concept

The design responds to the site's unique conditions by embracing the contrasting elements of fire and ice. By facing the building toward Hverfjall Volcano, the layout allows visitors to take in the views while fostering a connection to the land. The structure includes various practical areas, such as a parking lot, an open-air stage, a coffee shop, a meditation platform, a multipurpose room, and an exhibition hall. This arrangement supports a range of activities and enhances the overall experience for those who visit.

Sustainability Measures

Attention to sustainability is a key component of the design. The building avoids opening windows, which helps control the indoor climate and reduces energy use. A half-dug basement takes advantage of the geothermal heat from the volcano, maintaining a comfortable temperature inside. Additionally, the top of the building features a ventilation window that mimics a volcanic crater, allowing for airflow while also bringing in natural light.

Material Selection

Materials used in the construction include locally sourced lava rocks, which resonate with the geological identity of the area. Concrete is another material chosen for its strength and longevity. These selections reflect a commitment to authenticity and sustainability and ensure that the building is well integrated into its surroundings.

Design Details

Inside, the meditation room invites visitors to reflect on their connection to the natural landscape. This peaceful space encourages thoughtfulness about the relationship between nature and human life. Light filtering through the ventilation window creates a calming environment, allowing for quiet contemplation while offering views of Hverfjall Volcano. The design seeks to enhance visitors' awareness of the beauty and power of the environment surrounding them.
