Five distinct cubes are placed within the Icelandic landscape, designed to serve as a new destination for visitors near the Mývatn Nature Baths, which are an hour's drive from Akureyri. The concept emphasizes a thoughtful relationship between the buildings and their surroundings, aiming to maximize natural light while providing an enjoyable experience for users in a unique climate.

Design Concept

The cubes are arranged along a north-south axis to capture sunlight effectively, especially during the winter months. This orientation is essential for the project’s dual focus on a geothermal greenhouse and a restaurant. The slashed roof design allows sunlight to enter, particularly on the winter solstice, creating an environment that encourages plant growth and sustainability.

Functional Integration

Combining greenhouse and restaurant spaces fosters an interactive experience for visitors. People can engage in both the cultivation and enjoyment of food grown locally. This approach transforms the site from a mere tourist spot into a local gathering space, promoting community involvement and sustainable practices in agriculture.

Spatial Organization

Within the southernmost cube, a multipurpose hall serves different activities, such as yoga lessons and film screenings. This flexible design allows for various uses. The overall layout includes distinct functional areas, such as a restaurant entrance, a reception counter, and a greenhouse area, all configured to ensure smooth movement and ease of access throughout the building.

Materiality

Icelandic basalt is the primary material used, creating a visual and contextual link with the nearby landscape. This choice not only contributes to the overall look but also supports the structure. The result is a sense of place that feels harmonious with the environment.

The building features large openings that frame views of the Mývatn Nature Baths and the Kverkfjöll volcano. These elements enhance the connection between the architecture and the surrounding natural features, enriching the experience for all who visit.
