Turf-Roofed Longhouse Utilizing Thermal Mass for Sustainable Living

Project in-detail

Utilizing a turf roof and thermal mass construction, the design offers a contemporary reinterpretation of the Viking longhouse, creating a sustainable residential space that harmonizes with its rugged Icelandic landscape.
5 key facts about this project
01
Utilizes turf roofing for natural insulation and landscape integration.
02
Incorporates stone for thermal mass, enhancing energy efficiency.
03
Draws inspiration from Viking longhouse design, promoting historical connection.
04
Features large glass openings that connect interior spaces with nature.
05
Emphasizes a bent A-frame structure to optimize spatial dynamics.
The architectural project "Settlers of the Treeless Land" embodies a thoughtful examination of historical influences blended with modern sustainable practices. Situated in a challenging geographical region characterized by severe weather patterns consisting of snow, ice, and lava, the design serves as both shelter and response to its environment. The focal point of the design is the reinterpretation of historical Viking longhouses, framed within a contemporary context, emphasizing functionality and environmental integration.

Distinctive Structural Features

The project comprises three interconnected volumes that form a triangular geometric layout, referencing traditional longhouse designs. This structural organization not only defines the building’s silhouette but also promotes functional differentiation within the space. Each volume is designated for specific activities, including communal spaces, private living areas, and multifunctional zones. This arrangement strategically facilitates interaction while allowing for privacy when needed.

The use of natural materials significantly contributes to the project’s architectural identity. Wood is employed extensively, serving both structural and aesthetic roles. Turf, used as a roofing material, enhances insulation while promoting a seamless integration with the landscape. Stone forms the foundation, providing durability and thermal mass essential for maintaining comfortable indoor temperatures. Additionally, large glass openings create visual transparency, connecting occupants with the outdoor environment and enabling natural light to permeate the interior.

Innovative Sustainability Approaches

The project showcases innovative approaches to sustainability, addressing both material selection and energy efficiency. The choice of renewable materials, such as wood and turf, minimizes the carbon footprint while aligning with ecological principles. The orientation of the building is optimized for passive solar gain, harnessing sunlight effectively during colder months. Designed to adapt to both environmental conditions and user needs, the architecture allows for natural heating and cooling, reducing reliance on artificial temperature controls.

Moreover, the design incorporates water-resistant membranes aimed at prolonging the structure's lifespan in a region prone to moisture challenges. Each phase of construction emphasizes eco-friendly techniques, reinforcing the project's commitment to sustainable architecture.

Residents of this space benefit from a thoughtful organization that fosters community engagement while maintaining personal spaces. The design balances the need for social interaction with individual privacy, promoting a harmonious living environment.
