Cross-Laminated Timber Retreat Embracing Volcanic Landscapes with Sustainable Materials

Project in-detail

Embracing the rugged volcanic landscape, the retreat utilizes cross-laminated timber and locally sourced materials to create a resilient structure that supports winter recreational activities.
5 key facts about this project
01
Crafted from locally sourced cross-laminated timber, enhancing sustainability.
02
Features a bent A-frame design that maximizes natural light and views.
03
Incorporates charred wooden shingles for weather resistance and aesthetic appeal.
04
Engineered to withstand heavy snow loads typical of the region.
05
Designed with operable roof windows to facilitate natural ventilation.
The Overlapping Craters cabin is designed as a compact architectural project situated near the Krafla volcano in Iceland. This structure draws inspiration from the unique geographical features of volcanic craters in the region, showcasing a thoughtful integration of architecture with the surrounding landscape. The primary function of the cabin is to serve as a refuge and resource for visitors engaged in recreational winter activities, such as skiing, while also providing storage and ergonomic resting spaces.

The design comprises several functional zones within a unified structure. Key areas include an equipment tuning room for maintenance, a storage solution for outdoor gear, a lounge/rest area for relaxation, an information desk, refreshment space, and restroom facilities. The layout ensures efficient user flow, accommodating individuals transitioning between outdoor activities and indoor respite. The interior aspects are accentuated by Nordics Pine finishing, cross-laminated timber columns, and oak flooring, contributing to both aesthetics and functionality.

Unique Design Approaches

What distinguishes the Overlapping Craters cabin from similar architectural projects is its approach to environmental integration and sustainability. The design employs local Nordic pine, optimizing the use of regionally sourced materials and minimizing carbon emissions. Key features include solar water heat collectors, which leverage renewable energy for heating purposes, and operable roof windows that promote natural ventilation, enhancing indoor air quality.

The roof’s design serves a dual purpose; it not only provides a distinct silhouette reminiscent of overlapping craters but is also engineered to withstand substantial snow loads typical of the Icelandic climate. This attention to structural integrity ensures the cabin remains resilient against harsh weather conditions.

Architectural sections reveal how the thermal mass wall is implemented to regulate indoor temperatures, illustrating a clear understanding of climate-responsive design principles. The cabin harmonizes contemporary architecture with practical sustainability measures, highlighting architectural strategies that prioritize human comfort and environmental responsibility.

Utilizing effective architectural designs personalized to the surrounding landscape encapsulates the essence of this project. For those seeking a deeper understanding of its architectural plans, sections, and ideas, further exploration of the project presentation is encouraged. This will provide comprehensive insights into how the Overlapping Craters cabin redefines the relationship between architecture and nature within the unique context of Iceland.
