HVERFJALLSKAFFI operates as a greenhouse and visitor center located near the Hverfjall volcano in Iceland. The design concept emphasizes a strong connection between the built environment and the natural landscape. It aims to promote sustainability and education, allowing visitors to engage with local agricultural practices and explore the geological and ecological features of the area.

Design Concept

The layout encourages exploration, with pathways designed to lead visitors through various educational areas. These paths connect the greenhouse to displays that highlight the region’s geological history, volcanic activity, and native plant life. This structure enhances the visitor experience, providing ample opportunities to learn about the surrounding environment while enjoying the fresh produce offered.

Functional Spaces

The lower level features practical elements, including a coffee counter and dedicated areas for growing fruits and vegetables. The greenhouse contains both outer and inner planters, while a designated mushroom grow area is optimized for cultivation. There is also storage and processing space, which allows for efficient handling of harvested items. Educational displays turn the visit into a learning experience, informing guests about local agriculture and environmental stewardship.

Observation Areas

On the upper level, observation decks provide clear views of the volcanic landscape. These spaces are designed to frame the natural scenery, allowing visitors to appreciate the relationship between the built environment and nature. The observation areas invite visitors to pause, encouraging them to take in the dramatic contours and ecosystems of the region.

Architectural Details

Key architectural features include a thermal mass element that supports energy efficiency and sustainability goals. The entrance tunnel and arch port serve as transitions from the outside world to the welcoming atmosphere of the greenhouse and cafe. This thoughtful design detail empowers visitors to connect with both the architectural space and the rich natural setting, enhancing their overall experience.
