The project near Lake Myvatn reflects a modern approach to the traditional Icelandic longhouse, blending with its natural surroundings. Situated among birch trees and open land, it serves as a residence designed to foster a strong connection with the landscape. The design emphasizes creating a unique experience for those who inhabit the space, making use of the area's natural beauty while providing practical living areas.

Spatial Configuration

The longhouse spans below ground level, supported by vertical timber frames that define its structure. This choice creates a connection to the earth, making occupants feel closer to nature as they enter. Semi-opaque screens installed throughout allow soft light to filter into the interior, enhancing the visual relationship between the inside and outside.

Material Connection

Inside, the design utilizes heavy anchored stone walls to create smaller, intimate areas around an expansive open space. Shafts of light enter through elevated timber sections, adding variation to the environment throughout the day. This careful arrangement of materials highlights the importance of natural light and enriches the overall experience within the residence.

Natural Engagement

An oculus positioned in the walls provides framed views of nearby water, reinforcing the bond with the landscape. This feature not only adds an aesthetic touch but also invites the outside world in, encouraging occupants to connect with nature. The spa area, designed to evoke the feeling of a natural fissure in the rock, invites the eye upward, drawing attention to the landscape beyond.

Circulation and Interaction

Private guest pods are accessible via a timber stairway leading to a suspended walkway. This pathway connects to smaller branches that guide users through the space. This design enhances the experience by encouraging exploration and highlighting the relationship between various areas. Each pod offers a cozy environment, allowing a personal connection to the wider surroundings.

Natural light filtering through timber sections creates warm and inviting spaces, highlighting quiet corners throughout the interiors.
