Harnessing Snow for Thermal Regulation in a Lightweight ETFE Trekking Cabin

Project in-detail

Constructed with a lightweight ETFE shell that utilizes the igloo effect for efficient thermal regulation, this portable cabin offers a sustainable shelter solution tailored for the rugged Icelandic terrain.
5 key facts about this project
01
Constructed with a lightweight ETFE shell that enables snow accumulation for increased insulation.
02
Utilizes the igloo effect to harness natural thermal energy for internal heating.
03
Designed for easy assembly and transport, making it ideal for remote trekking environments.
04
Features an angular geometric shape that mirrors glacial formations, enhancing visual integration.
05
Adapts interior spaces for various activities, offering flexibility in usage for different group sizes.
The Glacial Tesseract is an architectural project designed as a portable trekking cabin, tailored for the extreme conditions of Icelandic landscapes. This project embodies a harmonious relationship between human habitation and the natural environment, reflecting a commitment to sustainability and innovative design practices. The cabin serves as a self-sufficient shelter that provides comfort and functionality for trekkers navigating rugged terrain.

The design is characterized by its angular geometric form which mimics the natural structures found in glaciers. This thoughtful integration into the landscape ensures that the cabin does not disrupt its environment, while also enhancing its aesthetic appeal. The use of materials, such as Ethylene Tetrafluoroethylene (ETFE) for the outer shell, demonstrates a focus on both durability and efficiency. ETFE’s insulating properties combined with its ability to accumulate snow provide effective thermal regulation, ensuring a suitable internal climate.

Adaptability is a crucial aspect of this project, allowing users to configure the space for various activities, such as sleeping, cooking, and socializing. The cabin's design enables a personalized experience, accommodating differing group sizes and their specific needs.

Innovative Thermal Management and Sustainability

A distinctive feature of the Glacial Tesseract is its approach to energy generation. By utilizing the 'igloo effect,' the cabin harnesses heat from the snow that accumulates on the ETFE surface. This method not only ensures warmth during harsh winters but also represents a sustainable way to leverage natural resources for human use. The project showcases an effective strategy for temperature control, allowing the interior climate to remain comfortable even as external conditions fluctuate significantly.

Portability is another significant attribute of the design. The cabin is constructed with lightweight materials that facilitate easy transport and assembly. This mobility allows adventurers to establish a shelter wherever needed, responding dynamically to outdoor conditions.

Enhanced Interaction with the Environment

In addition to adaptability and portability, the cabin is designed to engage with its surroundings visually and functionally. The geometry of the structure interacts with natural light, changing its appearance throughout the day. This feature is intentional, as it not only aids in navigation but also fosters a sense of connection between the occupants and their environment.

The internal layout is designed to optimize space and usability while remaining flexible for varying activities, enhancing the overall functionality of the structure. The careful consideration of design elements, including the configuration of the interior and choice of materials, reflects a comprehensive analysis of both user experience and environmental impact.

For those interested in the architectural design of the Glacial Tesseract, the project's presentation offers further insights into its architectural plans, sections, and designs. Exploring these elements will provide a deeper understanding of the innovative ideas and approaches that define this project.

Design a new small-scale home concept in the 10th edition of MICROHOME — 100,000 € prize + construction

Competition organisers

The 10th edition of the MICROHOME architecture competition invites architects and designers from around the world to explore the possibilities of compact, sustainable living. Hosted by Buildner in collaboration with Kingspan and Hapi Homes, this special edition challenges participants to design an off-grid, modular microhome for a young professional couple, with a maximum floor area of 25 m². Designs should prioritize innovation, efficiency, and real-world feasibility. 

A total prize fund of 100,000 € will be awarded, including three main prizes, the Kingspan Award, and the Hapi Homes Award, which will grant 15,000 € and lead to the construction of the selected design. The final registration deadline is September 25, 2025, and winners will be announced on Decebmer 9, 2025. For full competition details and submission guidelines, visit microhome.info.
