With walls constructed from hempcrete and an integrated hydroponic garden, this compact living space emphasizes sustainability and privacy while providing an affordable urban housing solution.
5 key facts about this project
01
Walls constructed from sustainable hempcrete provide superior insulation.
02
The design incorporates a hydroponic garden for urban self-sustainability.
03
Timber vertical planks enhance privacy while maximizing natural light.
04
Southern exposure is prioritized to optimize daylight in living spaces.
05
Flexible interior layout allows the bedroom to function as a workspace.

The Courtyard Microhome offers a practical solution for urban housing in areas facing land shortages and high real estate prices. The setting focuses on small, often overlooked plots found between single-family homes in metropolitan regions. The design aims to provide affordable living spaces that maximize land usage while ensuring privacy and a connection to nature.

Design Concept and Influences

The design draws on historical architectural styles, particularly the Roman Domus and Hui Style residences from ancient China. These influences shape the layout and functionality of the microhome. Its unique form fits well within irregular plots, making efficient use of limited space while maintaining a cohesive look in the suburban landscape.

Garden Integration

At the heart of the microhome is a garden that serves multiple functions. This space not only provides a quiet area for relaxation, but it also supports sustainable living through hydroponic gardening, allowing residents to grow their own vegetables. The garden enjoys southern exposure, which helps bring in natural light and improves the overall ambiance of the living areas.

Structural and Material Considerations

The flat roof design makes room for photovoltaic panels, promoting energy independence and sustainability. Timber serves as the main material for the home's structure and load-bearing walls, while hempcrete is used for insulation. This combination addresses energy efficiency and reflects a commitment to environmentally conscious building practices.

Interior Flexibility

Inside, the microhome features a versatile layout, particularly in the bedroom. By using vertical planks alongside the bathroom wall, the design eliminates the need for conventional doors. This approach allows light to flow freely throughout the space. The bedroom can easily shift from a resting area to a small workspace, meeting the demands of modern urban living.

The relationship between indoor and outdoor spaces enhances the daily living experience. The Courtyard Microhome illustrates a thoughtful approach to urban housing, integrating practicality and comfort in a constrained environment.

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.
