The Caldera visitor centre is set within the unique and rugged landscape of Dimmuborgir, Iceland. It serves as a gathering place for visitors who wish to explore the distinctive geological features of the area. The design concept is deeply interconnected with its surroundings, evoking the characteristics of a caldera and creating a meaningful relationship between the building and the natural environment.

Design Concept

The form of the visitor centre relates closely to the dramatic landscape. Sweeping roofs provide shelter and protection, creating a central terrace that encourages movement and interaction. The extended arms of the building frame views of the captivating terrain, directing visitors' attention to the striking natural formations that define the area. This thoughtful design integrates the architecture with the landscape.

Spatial Organization

The layout of the visitor centre is designed to promote fluid movement and engagement. A carefully routed path guides visitors through various areas, positioning the centre as a space for socializing and reflection. It includes important functions such as information resources and amenities, allowing individuals and groups to come together. The organization accommodates a diverse range of visitors, from solitary wanderers to families and local residents.

Materiality and Experience

Materials used in the building play a significant role in shaping its character. The outer surface is clad in lava stone, chosen to stand out against the dark landscape while providing warmth inside. This choice complements the environment and enhances the visitor experience. The spacious ceiling draws inspiration from ice formations found in volcanic caves, contributing to a unique auditory atmosphere. This connection to the geological surroundings enriches the time spent inside.

The visitor centre includes versatile spaces that support different activities, from educational workshops to community events. These design features ensure that the centre meets the varying needs of both travelers and local inhabitants. Each element contributes to an inviting environment that fosters exploration and connection with the remarkable landscape.
