### Overview

The Portal is a modular microhome design situated to address the needs of environmentally conscious users. The primary intent of the project is to promote sustainable living through efficient use of space and innovative materials, allowing for adaptation within various contexts. This approach supports low-impact lifestyles while integrating advanced building techniques.

### Spatial Configuration and User Experience

The design employs a strategic spatial organization, divided into functional zones that maximize usability within a compact footprint. A combined kitchen and living area enhance communal activities, while a screened-off bedroom area provides privacy. The incorporation of large windows and a fully glazed façade optimizes natural illumination, reducing reliance on artificial lighting. Innovative storage solutions, such as underbed compartments and wall-mounted shelving, further enhance the functional capabilities of the microhome.

### Material Selection

The Portal utilizes a range of materials that support its sustainability objectives. Kingspan Quadcore panels provide superior thermal insulation, while an aluminum façade ensures durability and minimal maintenance. Triple glazed glass installations enhance energy efficiency by maximizing daylight, and a Slimline Water Tank facilitates rainwater collection to promote self-sufficiency. Additionally, the structure's robust steel frame contributes to overall integrity, while solar panels installed on the roof harness renewable energy. Such material choices underscore the project's commitment to both environmental responsibility and modern design.

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.
