## Overview

The Heima - Pyramid is situated in a remote landscape in Iceland, where it explores the relationship between the built environment and natural surroundings. The design merges aesthetic considerations with functional requirements, aiming to adapt to both the local climate and the needs of its users while reflecting the principles of sustainability.

## Materiality and Environmental Integration

The project employs a diverse range of materials, each selected for its functional and aesthetic properties. The exterior features printed glass, which offers transparency and thermal insulation, enhancing the transition between indoor and outdoor spaces. Oak wood is utilized for flooring and structural elements, providing warmth and durability. The concrete shell serves as a robust foundation, its raw finish contrasting with the smooth glass surfaces—together, these materials foster a tactile richness in the environment.

To address the demands of the Icelandic climate, the design includes geothermal floor heating and a double glazing ventilation system that maintains air quality while improving energy efficiency. The pyramid form, combined with extensive glazing, not only maximizes natural light but also enables occupants to engage with the dramatic landscapes surrounding the structure, offering dynamic views throughout the day.

## Spatial Organization and User Flexibility

The interior layout prioritizes flexibility and community interaction while accommodating individual privacy needs. Design features include a service facility room optimized for practical household functions, adaptable guest rooms that can accommodate various configurations, and communal dining areas that encourage social engagement. The open-plan design, complemented by sliding partition walls, allows for modifications to space usage depending on the residents' preferences, facilitating both communal activities and private moments.

This thoughtful organization supports a lifestyle integrated with the environment, promoting a sense of community while respecting the personal space of its inhabitants.

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.
