The Vogáfjós Thermal Springs Guest House is an architectural project situated in the natural landscape of Iceland. This guest house is designed to offer visitors a unique experience rooted in the region’s volcanic heritage and surrounding birch forests. The structure complements its environment while providing functional spaces that enhance guest comfort and interaction with nature.

The project emphasizes a connection between the indoor experience and the outdoor landscape. Key architectural elements include a dynamic facade and strategically oriented interior spaces that maximize views of the Hverfjall volcano and the aurora borealis. The design utilizes simple geometries and earthy materials to create a cohesive relationship with the site.

Sustainable design practices are integral to the project. The guest house employs a Geothermal Ground Source Heat Pump (GSHP) for heating, which efficiently utilizes the region's geothermal resources. This approach highlights an ecological sensitivity typical of contemporary architecture in Iceland.

Unique Design Approaches The architectural design reflects volcanic forms through its fluid geometry. Curved and angular shapes replicate the organic characteristics of lava flows, which distinguish the guest house from more conventional designs. The extensive use of glazing invites natural light and provides visual access to the spectacular surroundings, establishing a dialogue between the interior and exterior.

The layout enhances user experience by maintaining a balance between private and communal spaces. The common areas are designed for social interaction, while guest rooms provide tranquility and privacy, encouraging relaxation and immersion in nature. This dual focus on connectivity and solitude is a significant departure from typical hospitality designs.

Material selection reinforces the project’s connection to the landscape. The primary material used is concrete, which resonates with volcanic rock and provides significant thermal mass. Additionally, wood accents add warmth to the interiors, while the strategic placement of glass integrates the building into its setting.

Architectural Elements The Vogáfjós Thermal Springs Guest House features a lobby designed to create an inviting atmosphere upon entry. The common living spaces facilitate engagement among guests and include designated areas for reading and leisure. The guest rooms are framed by expansive windows to offer picturesque views of the birch forest, enhancing the overall experience of the site.

Key features also include an outdoor hot tub positioned for optimal views of the night sky. This amenity underscores the project's commitment to delivering an authentic Icelandic experience by allowing guests to engage directly with the natural phenomena of the region.

For a deeper understanding of the Vogáfjós Thermal Springs Guest House, readers are encouraged to explore the detailed architectural plans, sections, designs, and ideas that define this project. An examination of these materials will reveal further insights into the architectural strategy and design methodologies employed throughout the project.

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.
