The microhome design comes from the unique context of the Midwest. It is a response to the need for flexible and accessible living solutions in today’s housing environment. The design focuses on creating a compact space that serves different types of occupants, including both younger individuals and the elderly. The overall concept emphasizes universal accessibility, sustainability, and efficient space use, making it suitable for both urban infill areas and rural, off-the-grid locations.

Universal Design Principles

At the heart of the microhome is the idea of universal design. This principle ensures that the home is functional and welcoming for people of different ages and abilities. The layout allows for smooth movement throughout the spaces, promoting comfort and independence. Key features are integrated throughout the home to enhance daily living and make the environment usable for everyone.

Sustainable Features

Sustainability is a major focus in the microhome design. It includes features that encourage energy efficiency and environmental responsibility. Solar panels are incorporated to allow for off-grid living, reducing dependence on conventional power sources. The roof collects rainwater, which is directed into a tank for graywater reuse. This system helps with plant irrigation and supports a green wall. Such sustainable aspects demonstrate a commitment to responsible living while keeping the home functional.

Adaptability and Accessibility

The design emphasizes adaptability, ensuring that each area maximizes usability. Floating shelves make it easy to see and access items while avoiding heavy cabinetry. The kitchen includes a dishwasher drawer to make tasks easier, especially for those with limited mobility. In the bathroom, features like grab bars and a shower seat provide safety and convenience for all users, making the home more user-friendly.

Elevated Structure

The microhome is designed as a three-level structure, allowing it to rise above the ground. This elevation provides covered parking, which helps to reduce land disturbance. It also makes the home appropriate for areas that might experience flooding or hurricanes. A chair lift is included to help individuals access different levels easily, reinforcing the commitment to making the home usable for everyone.

Details such as a fold-down dining table and movable storage solutions ensure that limited space is used efficiently. These elements support a living environment that can meet the changing needs of its occupants while remaining practical and straightforward.

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.
