## Project Overview

Haven is located in a rugged, icy landscape in Iceland, characterized by heathlands and sparse grasslands. This design aims to respond to the unique geographical and climatic conditions while serving as a multifunctional hub for summer and winter outdoor activities. It caters specifically to visitors engaged in skiing and other recreational pursuits, providing a space that integrates with its natural surroundings.

## Materiality and Sustainability

The architectural design employs a range of locally sourced materials, focusing on durability and environmental sustainability. Lava-based concrete forms the core structural element, significantly reducing carbon emissions in comparison to traditional concrete. Burnt wood cladding enhances aesthetic appeal and durability, while Icelandic corrugated metal roofing ensures resilience against harsh weather. Large glass expanses are incorporated to maximize natural light and create a visual connection with the exterior landscape.

The building also features a central lava stone, serving both structural and metaphorical roles, anchoring the design to the site and reflecting the region's geological identity. Interior spaces utilize light-colored wood and black rock, fostering a warm atmosphere that contrasts with the rugged exterior.

## Spatial Strategy and Design Outcomes

The design follows a V-shaped layout, optimizing solar access and facilitating user flow. High ceilings and open spaces contribute to an inviting environment, while flexible multi-functional areas accommodate a range of activities such as workshops and rest zones. A prominent lava rock fireplace serves as a focal point, enhancing the cozy ambience.

The organization of spaces effectively addresses operational needs, with technical rooms and storage areas positioned to promote efficiency. A mezzanine level provides additional viewing and relaxation opportunities, enhancing the overall user experience while maintaining a connection to the stunning landscape.

The integration of rain barriers, advanced insulation systems, and comprehensive drainage solutions ensures durability and environmental responsibility, aligning with contemporary sustainable building practices.

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.
