Combining cross-laminated timber and local volcanic concrete, this sustainable retreat utilizes geothermal heating to provide a comfortable haven for skiers while seamlessly integrating into the Icelandic landscape.
5 key facts about this project
01
Utilizes local volcanic rock concrete for enhanced thermal mass.
02
Features transparent polymer thatch to improve light transmission.
03
Incorporates geothermal heating systems to optimize energy efficiency.
04
Designed with a gabled profile for effective snow shedding.
05
Includes a viewing deck for unobstructed night sky observation.

## Overview

The LuminaSki Retreat is located in Iceland and aims to create a functional space for skiers while integrating with the surrounding natural landscape. The design prioritizes the relationship between the structure and its environment, reflecting an understanding of the users' needs and the aesthetic of the Icelandic terrain.

## Structural Integration and User Interaction

The design features a prominent crystalline roof that reflects the gabled profiles typical of Arctic architecture, which aids in snow shedding and enhances the building's aesthetic appeal. Exposed timber structures provide both stability and warmth to the interior, fostering a welcoming atmosphere. The large glass facades establish a transparent interface between the interior and the external environment, encouraging user engagement with the captivating landscape and allowing for immersive views of natural phenomena, such as the Northern Lights.

Careful attention to spatial organization facilitates straightforward movement throughout the building. Outdoor pathways promote active circulation, while designated functional areas—such as a ski equipment storage, a warmth area for relaxation, and an interactive information point—cater to the specific needs of visitors. A strategically placed viewing deck enhances the observational experience, providing panoramic sightlines of the surrounding mountain vistas.

## Material Choices and Sustainability

Material selection underscores the building’s commitment to sustainability, functionality, and visual harmony with its context. Local volcanic rock concrete, known for its thermal mass, is utilized to maintain a comfortable indoor climate during colder periods. Complemented by geothermal heating systems, this approach minimizes reliance on fossil fuels. The extensive use of timber contributes to the structural integrity and enhances the indoor environment with its natural texture.

Innovative materials, such as transparent polymer thatch, integrate traditional construction techniques with modern performance characteristics, improving the quality of light within the retreat. Large glass surfaces not only foster continuous visual engagement with the landscape but also reinforce the building's goal of maintaining minimal energy consumption through passive design principles. Overall, the project exemplifies a comprehensive approach to environmental integration and resource efficiency.

The Next House: USA — A Global Call to Reimagine the American Suburb

`
Competition organisers

Buildner is launching The Next House: USA, a global architecture competition that challenges architects, designers, and thinkers to reimagine the American suburban home for the 21st century. For decades, the suburban house has symbolized comfort and stability, but today it often reflects excess, isolation, and environmental strain. This competition asks: how can the American home evolve to address climate urgency, economic pressures, and shifting social values?

Participants are tasked with designing a prototype home of no more than 1,500 sq ft (≈140 m²) for a household of two adults and one child. The design should be compact yet generous, adaptable, sustainable, affordable, and replicable across diverse U.S. contexts. More than a design exercise, the competition aims to spark a conversation about how homes can support healthier, smarter, and more connected communities.

The total prize fund is $20,000 USD. The final registration deadline is May 20, 2026, and winners will be announced on September 22, 2026. The Next House: USA invites architects, students, and visionaries worldwide to redefine what the American home means today—and what it should mean tomorrow.
