The 18N Micro Home is located in Winnipeg, Manitoba, serving as a practical solution for a couple of junior accountants. This design focuses on creating a functional living space that accommodates work and leisure within a limited area. The project emphasizes efficiency, flexibility, and sustainable practices, showcasing a modern approach to compact housing.

Geometric Form and Spatial Efficiency

The main design feature is a lozenge-shaped module. This unique shape allows for maximum use of floor space while keeping a simple aesthetic. It stands in contrast to traditional square designs, providing better natural light and airflow. The two-story layout offers a clear distinction between living areas and workspaces. The ground floor includes a small kitchen, a living room that can double as a temporary bedroom, and a compact washroom. Upstairs, a versatile area can be adapted for sleeping or working.

Innovative Folding System

An innovative folding mechanism defines the second floor. This feature allows for a sloped wall that increases functional space without expanding the overall size of the home. The sloped wall adds visual interest and serves as an efficient storage solution. Every inch of space is utilized effectively, making the home not only practical but also aesthetically pleasing.

Sustainable Design Practices

Sustainability plays a significant role in the design of the 18N Micro Home. Solar panels on the southeast section of the roof are intended to provide half of the building's electricity needs. Water management is integrated into the design, with a cistern that collects rainwater and wastewater from the kitchen. This system supports irrigation for landscaping and encourages recycling, demonstrating responsible resource management.

Material Choices

The material selection includes local maple plywood and dark exterior cladding. These choices are both durable and contemporary, fitting the home’s overall look while ensuring it can withstand weather conditions. Energy-efficient LED lighting further enhances functionality, reducing energy use and supporting an environmentally friendly lifestyle.

Access to the second floor is provided by a retractable ladder. This clever design element maximizes space on the ground level while offering a practical way to reach the upper floor, embodying the principles of efficiency and convenience in compact living.

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.
