The Northern Light Retreat is situated in a landscape characterized by vast grass fields and bordered by a lake in the northern hemisphere. It draws inspiration from the phenomenon of the Aurora Borealis, creating a distinct experience for visitors. The design emphasizes sustainability and a minimal environmental impact through the careful placement of small, movable guest cabins. These cabins allow guests to engage with the natural surroundings while enjoying the beauty of the northern lights.

Architecture Concept

The overall design promotes a variety of pathways and connections that weave throughout the landscape. Each cabin is thoughtfully positioned to enhance the experience of being immersed in nature while providing a private view of the aurora. The shapes of the buildings reflect traditional Icelandic architecture, with simple forms and steeply pitched roofs that connect them to the surrounding geography. The architectural design creates a balance between built spaces and the environment.

Cabin Design

Guest cabins accommodate up to four individuals and are designed with a focus on comfort and practicality. Large glass surfaces allow abundant natural light into the space, providing direct views of the night sky and the northern lights. This design choice creates a feeling of openness and connection to the outdoors. Each cabin includes essential utilities designed to maximize space efficiency without sacrificing comfort for the occupants.

Central Building and Community Engagement

The main building serves as a social center for visitors, featuring a central courtyard that incorporates an interior garden and a large outdoor terrace. This arrangement encourages social interaction and gatherings, fostering a sense of community among guests. The narrow veranda on the northern side serves as a welcoming transition between the outside landscape and the interior space, enhancing the overall visitor experience.

Utility and Sustainability Features

To address practical needs, the design includes a biomass filtration system and a home sewage plant, which are necessary due to the lack of public utilities in the area. A groundwater filtration system ensures access to drinking water, while rainwater harvesting promotes sustainable practices. These elements enhance the retreat's eco-friendly approach and contribute to its self-sufficiency.

The design emphasizes thoughtful interactions between the buildings and the natural environment. The arrangement of cabins, along with pathways, creates varied experiences for each visitor. Elements like glass ceilings and open spaces prominently showcase the enchanting northern lights, allowing each person to appreciate the beauty of the natural world. The Northern Light Retreat stands as a well-considered response to its unique setting, focusing on comfort, community, and nature.
