## Project Overview
Capsule 29 is situated in Iceland, a location marked by stark environmental contrasts, from harsh outdoor conditions to the sheltered warmth of internal spaces. Designed as a multifunctional facility for skiers and hikers, it aims to meet the practical needs of outdoor enthusiasts in a region known for its spectacular yet challenging climate. The architecture reflects a thoughtful engagement with the site's formidable landscape while providing a secure environment for its users.

## Spatial Strategy
The design of Capsule 29 is characterized by its geometric form, featuring angular roofs and façades that echo the natural slopes of the surrounding terrain. This approach not only contributes to the aesthetic integration of the building within its setting but also serves to minimize its visual impact. A prominent ramp connects various areas of the facility to the exterior landscape, facilitating user movement and reinforcing the relationship between the built environment and the natural topography. Internally, the layout focuses on warmth and social connectivity, with open living areas featuring large windows that create a visual continuity with the snowy surroundings.

## Materiality and Sustainability
The materials selected for Capsule 29 emphasize durability and environmental compatibility, essential for withstanding Iceland's severe weather conditions. The exterior is primarily clad in red concrete, offering both resilience and warmth. Advanced insulation systems enhance energy efficiency, crucial for maintaining comfort in a cold climate. Additionally, polycarbonate panels are utilized in certain internal spaces to optimize natural lighting while ensuring privacy. Geothermal systems are integrated into the design, providing sustainable heating solutions that further address energy efficiency and environmental impact.

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.
