## Overview

The Compact House is situated within a desert environment, where its design responds to unique climatic challenges while integrating local cultural elements. The project aims to enhance modern comfort through sustainable practices and the incorporation of traditional building techniques, utilizing local materials to minimize environmental impact.

## Material Selection and Design Strategies

### Materiality

Key materials include rammed earth, which serves as the primary structural element with a thickness of 40 cm, providing excellent thermal inertia and low embodied energy. Sustainable certified wood is used for windows, aiding in carbon neutrality, while porcelain tiles are selected for their properties that complement radiant cooling systems. The basement is constructed with mass concrete, utilizing 100% recyclable components and local aggregates.

### Architectural Layout and Circulation

The spatial arrangement separates public and private areas to suit cultural norms. The basement accommodates utility spaces such as parking and storage. The ground floor features an open-plan design that integrates living areas with distinct private zones, including bedrooms. Outdoor spaces are carefully designed to foster interaction with nature, promoting outdoor living and communal activities. Separate circulation paths for public and private movement enhance privacy while facilitating social gatherings when required.

## Sustainable Design Approaches

### Passive and Active Strategies

The design incorporates passive strategies such as optimized window orientation and overhangs to maximize natural light and regulate heat, supported by cross-ventilation systems to enhance airflow. Active strategies include the installation of solar panels for renewable energy generation and geothermal systems for maintaining stable interior temperatures.

Through the combination of traditional and contemporary architectural practices, the Compact House exemplifies a commitment to sustainability and local tradition, creating a residence that meets the modern demands of its inhabitants while respecting its environmental context.

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.
