The "Lava Pebbles" project is an architectural design for a ski snow cabin located in Iceland, specifically in proximity to the Krafla Geothermal Center. This project aims to establish a strong connection between its architecture and the surrounding volcanic landscape. By responding to the unique geological features of Iceland, the cabin serves to provide a functional space for visitors engaging in winter sports while seamlessly integrating into its environment.

The design is characterized by its organic shapes that reflect the natural forms of lava pebbles, using soft curves and rounded volumes. This approach results in a structure that is not only visually appealing but also contextually relevant. The cabin’s layout incorporates different zones designed for relaxation, observation, and operational needs while promoting an interactive experience with the landscape.

Unique Design Approaches

The "Lava Pebbles" project distinguishes itself through its emphasis on sustainability and environmental integration. The architecture employs 3D-printed concrete, facilitating complex forms while minimizing material waste. The building is insulated with mineral wool and features reclaimed timber finishes that enhance its ecological footprint.

Since the project emphasizes passive design principles, it optimizes natural light and solar heat gain through strategically placed windows, allowing the interior spaces to remain comfortable without excessive energy use. The utilization of geothermal energy for heating further reinforces the cabin’s commitment to sustainability, showcasing a thoughtful approach to energy consumption.

Spatially, the design includes distinct areas such as a central gathering space, a viewing deck, and an equipment garage—all tailored to enhance user experience. The integration of landscaping that mimics local flora establishes a cohesive relationship between the structure and its surroundings, inviting users to engage with both the cabin and the natural environment.

Architectural Details

The structural integrity of "Lava Pebbles" is achieved through a combination of innovative construction techniques and high-performance materials. The use of 3D-printed concrete not only creates aesthetic value through intricate detailing but also ensures durability in the harsh climate conditions of Iceland. Large expanses of glass strategically positioned throughout the cabin maximize views of the surrounding landscape, effectively blending indoor and outdoor environments.

The design promotes a holistic user experience by facilitating movement between different functional areas. The architecture does not merely serve as shelter; it enhances recreational activities by providing opportunities for skiing, relaxing, and appreciating the unique geological features of Iceland.

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.
