Moka shop is a proposed visitor center located at the base of Hverfjall volcano in northern Iceland. It is designed to enhance the visitor experience by providing spaces for education, relaxation, and interaction with the dramatic volcanic landscape. The design is inspired by the explosive nature of volcanoes, which is visually represented in the building's octagonal shape, reminiscent of a moka pot, a traditional coffee maker from Italy.

Architectural Concept

The project features an octagonal floor plan that divides into distinct functional areas. These include a coffee shop, museum, bed and breakfast, lounge bar, information point, spa, office, and necessary technical buildings. Each unit serves a specific purpose while contributing to a cohesive visitor experience. This layout ensures that all facilities are within easy reach, allowing visitors to navigate comfortably through various activities.

Sustainability Measures

The design emphasizes sustainable practices throughout. It integrates wind power through the use of micro windmills, which harness renewable energy without visually disrupting the landscape. Geothermal energy is utilized to provide heating and sanitary water for the coffee shop, leveraging Iceland's natural resources efficiently. A rainwater harvesting system is also incorporated to collect water for non-potable uses, highlighting a commitment to conserving resources.

Materiality and Durability

Moka shop utilizes zinc, wood, concrete, and gravel as construction materials. These choices align with the local geological context while ensuring durability against the environmental conditions present in the region. The materials are selected not only for their functional properties but also for their integration into the surrounding landscape, creating a harmonious relationship with the natural environment.

Visitor Experience

The layout of Moka shop is designed to enrich the visitor experience. It creates a variety of spaces for relaxation mixed with areas where visitors can learn about the geological and historical significance of the site. Careful transitions between these spaces promote engagement and comfort, allowing visitors to immerse themselves in the unique surroundings.

The design highlights the connection between the building and the landscape, reflecting the powerful forces that shape the volcano. Each space encourages exploration and appreciation of the natural environment, inviting visitors to reflect on their experience in this fascinating setting.
