Designed to maximize views of the Northern Lights, the layout encourages outdoor engagement.
05
The facility incorporates geothermal energy for efficient heating and climate control.

## Overview
Located near the Krafla Caldera in Iceland, FISSURE is an architectural response to the region's distinctive geographical and cultural characteristics. This project integrates natural elements with traditional Nordic building techniques, addressing community needs while offering spaces for individual reflection. The design promotes a dialogue regarding the interplay between humanity and the environment, particularly in the context of nature's fragility and resilience.

## Material Selection and Performance
The project's material choices are central to its identity, emphasizing sustainability and respect for local traditions. Key materials include locally quarried volcanic basalt for the exterior walls, which enhances the building's integration into the rugged landscape, and cross-laminated timber (CLT) that provides both structural performance and warmth. Mass timber (GLT) is employed for broader structural components, while concrete serves multiple functional purposes throughout the facility. Unique to the design, the use of turf on the roof not only aids insulation but also further connects the structure to its environment. High-performance triple glazing enhances energy efficiency and offers occupants uninterrupted views of the surroundings.

## Spatial Organization
The exterior design reflects the dramatic Icelandic landscape, featuring a stark black basalt façade contrasted by a green insulated roof. This visual composition draws attention to the building's contextual setting and creates inviting outdoor spaces that respond to diverse climatic conditions. Upon entry, visitors are met by a grand staircase that symbolically bridges the geological past and contemporary experience. Inside, the space is segmented to facilitate interaction and privacy, comprised of airlock areas, multi-purpose relaxation zones, and observation lounges that promote engagement with the natural surroundings. Expansive windows optimize natural light, enhancing both the aesthetic quality of the interior and its energy efficiency, ultimately aligning with the project's environmental goals.

Unique characteristics of FISSURE further enhance its role as a communal space, incorporating elements that foster well-being, connection, and social interaction while honoring Icelandic architectural heritage and prioritizing low-impact construction methods.

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.
