The architectural design is set against a mountainous landscape in Iceland, focusing on a thoughtful integration with the surrounding environment. At its core, the concept explores an interface façade that redefines the traditional role of a façade, acting as both a divide and a connection between indoor spaces and the natural world. The primary function involves a greenhouse that supports local agriculture while also serving as a gathering space for community activities.

Design Concept

The interface façade moves beyond the typical function of a wall. It creates a connection that allows natural elements to flow into the building. The structure is designed as a single-story volume partially embedded in the ground. This choice helps minimize the visual impact and enhances the relationship with the land.

Community Engagement

At the heart of the project is the greenhouse, designed to grow vegetables for local distribution. These greens may reach various venues, such as the Diamond Circle visitor center and nearby restaurants. This effort encourages community ties and emphasizes the value of local resources. Visitors are invited to participate in picking fresh produce, which reinforces their connection to the food they eat.

Spatial Organization

Spaces are thoughtfully arranged and include areas like the restaurant, hall, and administration. This layout supports community gatherings while providing clear circulation paths for different activities. The greenhouse features a glass roof, allowing ample natural light for plant growth, while interactive zones are shaded by wooden roofs, offering comfort for those visiting.

Sustainability Measures

Sustainability plays a vital role in the design. High-temperature heat source water from a nearby thermal power plant is used to maintain optimal conditions in the greenhouse. Rainwater is collected for irrigation, ensuring an efficient water use. Carbon dioxide captured from nearby facilities contributes to the greenhouse's growth cycle.

Guests enjoy views of Hverfjall Volcano, creating a direct connection to the Icelandic landscape. The design elements thoughtfully encourage interactions between the built environment and nature, emphasizing the importance of both in everyday life.
