Geothermal energy powers a thoughtfully designed space that combines a Restaurant and Greenhouse, utilizing skylights and stack ventilation to enhance sustainability and food production.
5 key facts about this project
01
Geothermal systems provide energy for heating and cooling.
02
Stack ventilation enhances natural airflow throughout the spaces.
03
Skylights are designed to frame the night sky and reduce energy use.
04
The layout facilitates a direct farm-to-table experience for guests.
05
Sustainability principles guide the design, minimizing environmental impact.

The design in the Myvatn region of Iceland explores the relationship between the landscape and the culinary experience through the integration of a Restaurant and Greenhouse. It focuses on sustainability and the unique geological features of the area, illustrating how food is produced and consumed. The layout is carefully structured to provide both distinct and interconnected experiences, guiding visitors to appreciate the connection between growing food and enjoying it as a meal.

Design Concept

At the core are two separate spaces: the Restaurant and the Greenhouse. Each functions independently, yet their forms engage in conversation with each other. This interplay encourages exploration of the site. The layout groups areas into two categories: the Green, for circulation between the greenhouses, and the Red, which includes the Food & Beverage sections. This arrangement simplifies movement and enhances the understanding of how food travels from the greenhouse to the dining table.

Sustainability and Environmental Engagement

The design places a strong emphasis on sustainability. Natural airflow is optimized through stack ventilation, which reduces reliance on mechanical systems. Skylights are skillfully positioned to capture natural light while framing the night sky. This connection between inside and outside not only brightens the spaces but also enhances the experience of being in such a beautiful location. Nature becomes part of the architecture, contributing to the overall atmosphere.

Lighting Strategy

A careful lighting strategy was implemented to protect the dark sky of the region. Illumination is directed downwards, minimizing light pollution. This approach highlights a commitment to environmental balance while respecting the area's night environment. Each architectural decision aligns with the surrounding landscape, reinforcing the responsibility to both the ecosystem and the local community.

Using local materials emphasizes the idea of sustainability and helps reduce transportation emissions. Every element supports the notion that architecture can fulfill practical needs while offering insights into food systems. The form of the Restaurant and Greenhouse stands out against the landscape, showcasing the relationship between the built environment and nature, while the design of the skylights captures the changing light throughout the day in a dynamic and engaging way.

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.
