The Geisli Pavilion is located in Iceland, influenced by the natural beauty and geological features of the area, particularly the Grjótagjá caves. It is designed to function as a space for exploration, reflection, and social interaction. Central to the pavilion’s design is the concept of reflection, which highlights how light and sound can interact with the space and surroundings, creating a meaningful experience for visitors.

Architecture Concept

The design incorporates geometric shapes that form cone-shaped rays and beams, allowing the structure to relate closely to the landscape. These architectural elements frame views of the surroundings while guiding people through the space. The building is organized around a central convergence point, where various functions are housed within separate areas that fall into the defined beams. This arrangement creates both visual interest and practical use.

Visitor Experience

Visitors begin their journey at the Grjótagjá car park, where they first encounter the beauty of the caves. After exploring the caves, they walk along a bridge that leads to the reception area, which features distinct angular designs. This initial pathway helps orient guests and emphasizes the natural terrain of the site, establishing a connection between the structure and the landscape.

Spatial Planning

Inside the pavilion, a sunken cinema offers a unique viewing experience. Skylights above allow natural light to enter, enriching the atmosphere. A ribbed walkway directs guests toward the café, where indoor and outdoor spaces blend, encouraging interactions with nature. This planning enhances both comfort and engagement, making every moment spent inside feel connected to the outside.

Design Details

The pavilion’s gallery includes a green roof that slopes to provide open-air views. This feature promotes environmental sustainability while allowing natural light to filter into the area. Visitors can find solitude in designated contemplation spots, creating spaces for personal reflection. The bar and private dining spaces are designed for social gatherings, set against the backdrop of the surrounding landscape.

The interplay of light and shadow generated by the angular beams adds depth to the design. This interaction underscores the building's relationship with its environment and enriches the overall experience for visitors.
