**Project Overview**
The Éstia Cabin is situated in the Nyufat region of Iceland, designed to reflect the region's unique geological features and geothermal activity. Inspired by cultural elements of warmth and comfort, the cabin aims to serve as both a retreat and a gathering space for visitors, blending with the surrounding landscape and encouraging interaction with the environment.

**Spatial Strategy**
The architectural form of the cabin is informed by the natural topography, characterized by multiple tiers and slopes that evoke a flow reminiscent of lava formations. This configuration minimizes visual disruption and integrates the structure into its context while enhancing sustainability through features such as rainwater harvesting. Internally, the design promotes flexibility with open spaces suitable for a range of activities, from communal gatherings to individual retreats, complemented by expansive windows that frame scenic views.

**Materiality and Adaptability**
The project employs a carefully curated selection of materials that highlight functionality while establishing a connection to the local environment. Key elements include 3D printed concrete modules for rapid construction, wooden boards to add warmth, and extensive glazing to maximize natural light. Stone handles and textured flooring draw tactile connections to the Icelandic landscape. Additionally, the cabin's design accommodates seasonal variations, allowing it to function as a seminar space during autumn or a shelter for winter activities, thereby demonstrating responsiveness to the region's climatic conditions.

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.
