The Turf House Cafe is located in Iceland, designed to blend with its stunning natural surroundings while providing a space for visitors to gather and relax. The design draws inspiration from traditional turf houses, incorporating elements that pay homage to Iceland’s architectural heritage. With its focus on creating a connection between indoor and outdoor environments, the cafe encourages visitors to enjoy the beauty of the landscape.

Spatial Organization

The layout consists of four distinct volumes, each thoughtfully arranged to serve different functions: a visitor center, a coffee shop, an exhibition hall, and office areas. This careful arrangement allows for easy movement between spaces, making it convenient for visitors to explore all that the cafe has to offer. Each volume is oriented to take advantage of views of the nearby volcano, enhancing the overall experience with striking scenery.

Material Integration

The cafe features a turf roof, which provides effective insulation, keeping the interior warm and comfortable. The combination of stone and glass not only grounds the structure but also creates a light-filled atmosphere. The stone connects the building to its environment, while the glass walls help dissolve the boundary between inside and outside. This integration of materials respects local traditions while ensuring a modern function.

Engagement with Nature

The coffee shop stands out as the central volume, designed as a peaceful escape for visitors. A unique funnel-shaped garden separates the parking area from the building, offering a natural transition that reinforces the connection to the landscape. Large windows invite natural light and frame breathtaking views of the volcano, encouraging guests to engage with the outdoor scenery while enjoying their time inside.

Unique Architectural Features

An interesting aspect of the design is the gallery, which is accessible from the coffee shop. This gallery connects to outdoor areas and resting zones, allowing visitors to explore further. A mirror tunnel links the gallery to the parking lot, providing a reflective experience as visitors approach. This feature adds an engaging architectural element, enhancing interaction with the natural environment and inviting visitors to appreciate the surrounding beauty.

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.
