### Turf Cabin Project Overview

Located in the rugged landscapes of Iceland, the Turf Cabin project reflects an innovative approach to architectural design that aligns traditional elements with contemporary functionality. Designed to serve as a refuge for trekkers, the cabins incorporate characteristics of traditional Icelandic turf houses, such as earth-sheltered forms and green roofs, while introducing a modular and angular design that interacts dynamically with the surrounding topography.

### Spatial Configuration and Structure

The design comprises triangular units that delineate essential areas—storage and toilet, a combined kitchen and living room, and shower and sleeping areas. This configuration facilitates compact living spaces tailored to the needs of travelers. Each cabin's modular framework allows for easy transport and assembly, catering to remote locations. The architectural silhouette features sharp angles and a dynamic roofline, mirroring the mountainous terrain and enhancing visual engagement with the landscape.

### Material and Sustainability Features

The construction employs cross-laminated timber (X-Lam) for structural stability, complemented by local stone cladding that enhances thermal efficiency while integrating the buildings into their environment. The grass roofs, a nod to traditional Icelandic architecture, provide insulation and minimize visual impact. Sustainable technologies, including photovoltaic systems for renewable energy, geothermal heating, and rainwater collection initiatives, underscore a commitment to ecological responsibility and energy efficiency. Expansive glass panels enhance natural lighting and ventilation, connecting users with the surrounding scenery while creating an inviting atmosphere.

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.
