Scoria Walls Bridging Tectonic Plates Within a Geothermal Visitor Center

Project in-detail

Positioned between tectonic plates, the structure utilizes scoria for its walls, embodying local geological identity while functioning as a visitor center that offers unique views of the surrounding geothermal landscape.
5 key facts about this project
01
Positioned between the Eurasian and North American tectonic plates.
02
Constructed with local scoria for thermal efficiency and environmental harmony.
03
Features zigzagging stair patterns that reflect traditional Icelandic knitting.
04
Includes observation areas specifically designed for viewing the aurora borealis.
05
Elevated pathways minimize disruption to the surrounding volcanic landscape.

The Stitch Tower is located on the northeast coast of Iceland, near Lake Mývatn. It is set in a distinctive volcanic landscape marked by geological activity. The design centers around the unique position of the tower, which sits between the Eurasian and North American tectonic plates. This creates a visual connection between the two continents. The building functions as a visitor center, offering various amenities and observation points that encourage guests to appreciate the surrounding nature.

Architectural Language

The design draws inspiration from Icelandic culture, particularly the practice of knitting, which is an important part of local life. The zigzagging stairs of the tower are reminiscent of knitting patterns, linking cultural expressions with the architecture itself. This thoughtful approach helps in organizing the space and guiding visitors as they move through the structure, creating a sense of place that reflects the community’s traditions.

Materiality and Sustainability

Material choice is significant in the Stitch Tower's construction. It utilizes scoria, a type of lava rock found locally, for the walls. This material connects the building to its geological setting and provides thermal efficiency. By using scoria, the project reduces the environmental footprint associated with transporting construction materials, highlighting a commitment to sustainability and local resources.

Integration with the Landscape

Designed to minimize its impact on the surrounding terrain, the Stitch Tower features pathways that are elevated on posts. This approach preserves the natural layout of the landscape, allowing for an uninterrupted view of the area. Visitors experience the environment more fully while walking along these raised paths. This careful integration reinforces the relationship between the building and its striking natural setting.

Observation and Experience

The Stitch Tower includes observation areas for viewing the aurora borealis, a natural light display common in this region. The top of the structure features a circular window that provides clear views of the sky. This design detail invites visitors to connect with the natural world above them. Through its thoughtful geometry and placement, the building serves as a point of interest in Iceland’s captivating landscape.
