The Pavilion near the ancient caves of Grjótagjá is designed to connect people with the unique Icelandic landscape. It serves multiple functions, including spaces for a cinema, dining, and exhibitions, all while focusing on nature preservation. The overall concept centers on blending the building with its environment, reflecting a growing understanding of architecture's role in sustainability and ecological awareness.

Architectural Concept

The design starts from the ground and rises in a way that resembles a protective cape. This shape provides a sheltering function, while also allowing the building to engage with the natural topography. The Pavilion is set back from the road, creating an outdoor space that offers visitors a sense of intimacy and privacy amid the surrounding landscape.

Natural Light Integration

Strategically placed openings in the roof allow natural light to flood into the space from the south. This design choice brightens the interior, making it an inviting place for visitors. The ample light reduces reliance on artificial sources, establishing a more direct connection to the outside.

Water as a Design Element

Water plays an important role in the design and is enclosed within a distinctive geometric form. This feature serves to highlight the significance of water within Iceland’s environment. The presence of water creates a sensory experience, helping visitors engage more fully with nature.

Interior Spatial Organization

The Pavilion is divided into three main areas: a cinema, a restaurant, and an exposition center. Each space is designed for different activities while maintaining an open layout that encourages movement and exploration. The cinema features triangular shapes drawn from the local geology and uses lighting techniques to enhance the visual experience. The restaurant, accessible through a corridor, provides views of the caves, strengthening the connection between the building and its natural surroundings.

The roof’s unique curvature is designed to manage rainwater effectively. It directs water toward the central enclosed water feature, which serves as both a visual interest and functional element within the building. This thoughtful design detail reinforces the relationship between the architecture and the natural environment, creating a space that is both practical and aesthetically appealing.
