## Overview
The Micro-Assembly Home is situated within a wooded habitat, designed to provide an adaptable living environment that aligns with contemporary architectural standards emphasizing sustainability. The project utilizes a compact footprint, aiming to deliver versatile spaces suitable for a professional couple while minimizing ecological impact. Modular construction techniques serve as the foundation for its assembly, relying on a limited range of materials that facilitate efficient building processes and resource conservation.

### Spatial Efficiency and Adaptability
The design prioritizes the intelligent use of space, maintaining a total area of 25 square meters while promoting a sense of openness and functionality. The layout includes innovative storage solutions and convertible spaces that cater to varying daily needs. A sliding floor platform allows for multiple configurations, enhancing the home’s usability for both work and leisure activities. The distinct modular construction features a slotted assembly of four planks, enabling straightforward transportation and assembly by individuals with minimal construction experience.

### Material Selection and Environmental Considerations
The selection of materials emphasizes sustainability and regional resource utilization. Wood serves as the primary material, underlining its renewable properties, while structural reinforcements and aesthetic components include metal and glass, respectively. The integration of a rainwater collection system not only aids energy efficiency but also reinforces an off-grid lifestyle, promoting self-sufficiency. This strategic approach to materiality enhances both the building's aesthetic and its functional performance, ensuring durability while supporting ecological principles.

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.
