The project draws inspiration from traditional Icelandic Turf Houses, representing important elements of the country’s heritage while prioritizing sustainability. Located in a picturesque landscape, the design functions as a multipurpose facility that includes a restaurant, coffee shop, greenhouse, and terrace. Its overall concept blends modern architectural practices with historical references, creating a functional and inviting space for visitors.

Design Integration

The layout focuses on a central multipurpose hall that encourages movement and interaction among different areas. Each space is organized to allow easy access while enhancing the visitor experience. Large windows and openings frame views of the surrounding environment, letting guests enjoy the scenery of Hverfjall volcano and Myvatn Nature Baths.

Sustainability Features

At the heart of the design is the greenhouse, which features a south-facing facade to maximize sunlight for growing local vegetables and herbs. This thoughtful inclusion highlights a commitment to ecological responsibility and strengthens connections to local food sources. The design ensures that natural light is present throughout the building, creating a welcoming and bright atmosphere.

Structural Composition

A load-bearing timber modular system provides the foundation for the structure, allowing for an adaptable and flexible interior layout. Concrete pillars offer stability while being covered in wood cladding, which contributes to a consistent look. This combination supports openness and functionality, catering to a variety of uses without compromising the building’s integrity.

Landscape and Biophilic Design

The green turf roof serves as an important feature, providing insulation while helping the building blend with its environment. This aspect not only improves energy efficiency but also promotes biodiversity by offering a habitat for local wildlife. Thoughtful landscaping reinforces the connection between the building and its natural surroundings, adding to the overall design narrative.

The architecture culminates in a cohesive structure that uses natural materials to foster a connection with the landscape. The design reflects a contemporary approach to traditional forms, focusing on functionality and connection with the environment.

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.
