The design located in Iceland, near Myvatn Nature Baths, creates a connection between the built environment and its natural surroundings. The facility serves several purposes, including a multipurpose room, a vegetable garden integrated with a restaurant, and a greenhouse. The design concept centers around an interior promenade that guides visitors through these spaces, enhancing their experience and interaction with nature.

Design Flow

The layout establishes a clear pathway for visitors, starting at the entrance on the north side. This entrance is marked by a distinct slit that frames views of the outdoors. It is not just an entry point; it sets the tone for what lies ahead. Inside, the space promotes easy movement. Visitors can navigate from one area to another without confusion, enjoying the journey through the different sections.

Sustainability Focus

A key feature of the design is the connection between the restaurant and the vegetable garden. This integration highlights a commitment to sustainability. The garden provides fresh produce for meals and offers visitors a chance to engage with the process of growing food. This relationship between food cultivation and dining reflects an increasing awareness of ecological issues in architecture.

Materiality

Concrete serves as the primary material for this building. It is chosen for its strength and ability to handle Iceland's tough climate. The use of concrete can be seen throughout, offering stability to the structure and grounding it into the landscape. This choice also brings cohesion to the design, creating a unified look that fits well within its environment.

Unique Interaction

The design encourages visitors to engage with both indoor and outdoor spaces. Moving from the multipurpose room to the greenhouse becomes more than just a walk; it is an experience that connects people with nature. Large windows help in this interaction, framing views of the surrounding landscape. The architecture does not simply exist alongside nature; it invites visitors to take in the scenic beauty of the Icelandic terrain.

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.
