### Overview

The "Atmosphere" micro home is designed as a residential solution that integrates 3D printing technology and sustainable building practices. Located in an environmentally sensitive setting, this project aims to provide a cost-effective and eco-friendly living alternative while redefining spatial configurations within housing. With a total floor area of 25 square meters, the design emphasizes a playful and organic aesthetic inspired by natural forms, such as soap bubbles and astronaut helmets.

### Spatial Organization and Interaction

The micro home features an innovative spatial strategy comprised of several interconnected spheres, each assigned a specific function. These include a living area, kitchen, bathroom, bedroom, and an observation nook, all designed to optimize usability and encourage creativity. The prominent use of large, spherical windows allows natural light to flood the interiors, enhancing comfort and promoting a sense of openness. Additionally, the design incorporates an inviting outdoor garden area to facilitate interaction with the environment and provide opportunities for relaxation outside the household.

### Material Selection and Environmental Impact

Key materials for the construction of "Atmosphere" include 3D printed concrete, which significantly reduces the carbon footprint by sourcing sustainable components, resulting in a footprint approximately 30% smaller than traditional methods. Large glass windows enable expansive views and natural daylight penetration, while wood elements contribute warmth and texture to the interior finishes. Metal components are strategically utilized in the framework and accents to reinforce structural integrity and modernity. The construction methodology emphasizes low waste, supporting eco-friendly practices by minimizing material usage and promoting efficient production techniques.

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.
