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 Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process.

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization.
