The project at Hverfjall is located in a striking landscape marked by volcanic formations that create a unique visual experience. Functioning as a visitor center, the building is designed to engage with the dramatic scenery while providing spaces for visitors to gather and explore. The central theme is the relationship between architecture and the natural environment, aiming to enhance the experience of those who come to this remarkable setting.

Design Integration

A hiking path leads visitors toward a notable geological feature—a crevice in the earth that serves both as a visual anchor and a connection to the geological past. At the base of the crevice, a courtyard provides a sheltered area that promotes interaction with the natural surroundings. The raised mass of the building wraps around this space, demonstrating a thoughtful respect for the landscape's character while accommodating various visitor activities.

Architectural Form

The shape of the building responds to local architectural traditions, with a roof designed to function as a walkable hill. This design allows the structure to blend into the site’s topography. The façades stretch horizontally toward the volcano, creating opportunities for visitors to enjoy views of the mountain. This configuration reduces visual impact and ensures a smooth connection between inside and outside, encouraging engagement with the landscape.

Materiality

Durable materials are used, with weathering steel acting as the main facade material. The roof is covered with tuff and soil, echoing the region's geological features. This choice not only reinforces the connection to the landscape but also promotes a sustainable approach. The materials work together to withstand local weather conditions and maintain a practical yet visually appealing exterior.

Spatial Organization

Inside, the visitor center features a range of spaces, including a café, exhibition area, and lobby. These areas are arranged to encourage exploration and interaction among visitors. Sunken spaces allow natural light to flood in, enhancing the experience of being within the building. The design keeps a low profile, allowing visitors to focus on the natural surroundings while enjoying the functions provided.

Large openings in the walls bring in light and views from outside, creating a continuous connection between the building and its environment. The experience unfolds both inside and out, inviting visitors to appreciate the beauty of Hverfjall and its geological heritage.
