The Grjótagjá Movie Cave in Iceland combines film and nature in a thoughtful architectural design. Located close to the famous Grjótagjá Caves, the pavilion aims to honor the country’s cinematic history while respecting the surrounding landscape. The overall goal is to create a balance between the new structure and the existing environment.

Design Concept

The pavilion consists of a ground floor and an underground hall. Its roof rises from the ground on one side while sloping down on the other. This shape allows the natural landscape to flow across the structure. Visitors can enjoy elevated viewpoints that provide unique sights of the volcanic terrain. There are also “dug-in viewpoints” next to the building, which offer a more intimate connection to the landscape.

Spatial Organization

Visitors access the building by following a path that leads to an entrance corridor. Inside, wardrobe and restroom facilities are immediately to the right, while a gallery displaying the history of Icelandic film is to the left. The gallery has horizontal shades that let in natural light, focusing attention on the exhibits. This layout connects guests to the local film heritage.

Functional Areas

The ground floor includes various spaces that enhance visitor experience. There is a bar with multi-level seating, a ticket counter, and changing rooms. Each space serves different needs and encourages social interaction. The underground section features a 50-seat cinema, thoughtfully designed with accessibility in mind. It ensures that all visitors, including those with mobility impairments, can enjoy the film experience comfortably.

Sustainable Design Features

Drawing from traditional Slovenian rural architecture, the structure incorporates load-bearing elements similar to those used in hay-drying buildings. Locally sourced sheep wool insulates the walls, improving energy efficiency. The building also includes a green roof and triple-glazed windows to further enhance performance. Geothermal heating ties the building to Iceland’s sustainable practices.

Large windows throughout the space offer excellent views of the surrounding landscape. Select seating areas frame these views, allowing the outside environment to play a significant role in the cinematic experience. The design integrates the beauty of the Icelandic landscape with the enjoyment of film, creating a space that celebrates both art and nature.
