The Iceland Thermal Springs Guest House sits in a unique landscape that utilizes the region’s geothermal resources. It serves as a wellness retreat, connecting visitors to the natural surroundings while providing spaces for both communal interaction and private relaxation. The design thoughtfully separates public areas from those meant for private use, creating distinct experiences that cater to diverse guest needs. The inclusion of thermal springs as central features emphasizes the cultural significance of these natural resources in Iceland.

Architectural Integrity

The project features an anti-seismic structure, which is essential for safety in an area that is susceptible to earthquakes. This design choice ensures that the building remains stable and secure, allowing for expansive interior spaces. The layout promotes easy movement throughout the guest house while maintaining a sense of openness and connectivity.

Sustainability Measures

Geothermal heating and cooling systems are key elements of the design, efficiently harnessing local energy sources to reduce environmental impact. The use of solar energy also contributes to energy savings and supports sustainable practices in construction. This focus on energy efficiency is not only a practical choice but also reflects a growing awareness of ecological responsibilities.

Material Selection

Selected materials play a significant role in the overall design. Ridge wood boards, panels from Ruukki Forma Lamella Cor-Ten 30, and multi-laminated wood beams have been chosen for their strength and aesthetic qualities. Reinforced concrete is employed in the foundation and slabs, providing stability while accommodating large windows that allow natural light to fill the space.

The design further incorporates top-hung roof windows, enhancing ventilation and letting in ample daylight. This feature contributes to a warm and inviting atmosphere, encouraging guests to enjoy both the building and the beauty of the landscape around it.

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.
