Norðurljós hús is a unique design located in Iceland, serving as a house and movable bedrooms for watching the aurora borealis. The project focuses on the connection between people and nature, allowing residents to experience the beauty of the northern lights. The structure showcases a blend of traditional Icelandic influences and modern building techniques, resulting in a practical yet aesthetically pleasing design.

Design Concept

The idea behind the design includes movable bedrooms made from a tetrahedral frame, reminiscent of A-frame mountain shelters. This frame is lightweight and allows the rooms to be oriented toward the north, providing optimal views of the auroras. The upper parts of these bedrooms are composed of glass, which enhances visibility of the lights and creates a strong bond between occupants and the sky.

Spatial Arrangement

The layout of Norðurljós hús is carefully organized. The main house is partially built into the ground, utilizing the natural landform for insulation and protection against Iceland’s wind. This arrangement effectively separates shared living spaces from private areas. The south-facing rooms, which include kitchens and living rooms, are designed to take in sunlight and views of Lake Mývatn. In contrast, the north-facing night rooms feature skylights allowing for direct views of the auroras.

Materials and Sustainability

The selected materials of the project support its overall function and appearance. Walls are constructed from basaltic lava stone, offering good insulation properties and blending well with the local environment. Corten steel is used for roofs and window frames, providing a robust structure that withstands the elements. Glass is used extensively throughout the design, allowing natural light to fill the interiors and maintain a visual connection with the outdoors. Turf is also integrated for insulation, reflecting traditional Icelandic building practices and reinforcing the project's local ties.

Environmental Strategy

Norðurljós hús employs an environmental approach to its design. The water management system is off-grid, relying on rainwater and snowmelt captured from the roof and stored in underground tanks. Greywater is processed through a phyto-purification system using cascading ponds, ensuring minimal environmental impact. The building utilizes electricity from Iceland’s geothermal energy sources, which further supports its sustainability goals.

With large glass surfaces throughout, the design encourages natural light to enter the living spaces while keeping the stunning views of the landscape at the forefront. Residents can truly appreciate the magical experience of watching the aurora borealis from their own bedrooms, surrounded by the beauty of Iceland’s nature.
