The KEILAN project is located in Mývatn, Iceland, where remarkable volcanic landscapes and rich ecology create a unique setting. Designed as a place for multiple functions, KEILAN aims to connect with the natural environment while providing a space for visitors. The concept draws inspiration from the region's volcanic forms, resulting in a design that reflects the local topography and offers a variety of activities for residents and tourists.

Architecture Concept

The design consists of two conic shapes that serve to separate different functions within the building. This arrangement allows for distinct spaces while still maintaining a unified overall image. By organizing the layout in this way, the design encourages easy movement throughout the building. Visitors can navigate the reception area, café, and exhibition halls without difficulty. The forms of the building echo the surrounding landscape, enhancing the connection to the environment.

Spatial Configuration

Within the visitor center, a central open hall welcomes guests. Flanking this space are a café and a souvenir shop, which invite casual interaction among visitors. Key functional areas are thoughtfully arranged for convenience, and the exhibition space on the first floor is adaptable for various purposes. A lookout arch on the second floor provides sweeping views of Lake Mývatn, allowing visitors to engage with the natural beauty from inside the building.

Environmental Integration

Sustainability plays an important role in the design of KEILAN. Open spaces between the structures enhance natural airflow and connect the building to the outdoors. The thick exterior walls support the conic shape while providing insulation from Iceland's harsh weather. A vegetated roof helps keep the building warm and reduces energy costs, making it more environmentally friendly.

Unique Design Features

A rainwater harvesting system is incorporated into the design to promote responsible water usage. This system captures rainwater for use in toilets, which minimizes waste. The extensive use of glass throughout the building encourages natural light while offering views of the landscape, fostering a welcoming atmosphere. The thoughtful design details contribute to a strong visual presence that resonates with the context of Mývatn.
