The CACATOO LODGE Microhome serves as a comfortable space for isolated living, positioned away from the busy urban setting. This compact, cube-shaped dwelling emphasizes self-sufficiency and a strong connection to nature. The design fosters a lifestyle where people can escape their daily routines, allowing for a peaceful retreat that harmonizes with the environment.

Design Concept
The form of the microhome is characterized by a simple cube structure that is elevated above the ground. This elevation distinguishes the building visually and allows for the integration of necessary external facilities and parking spaces, enhancing its overall functionality. The design captures essential aspects of modern living while maximizing the use of the surrounding land.

Spatial Arrangement
The microhome is oriented northeast-southwest to take advantage of natural light throughout the day. This careful positioning lets morning sunlight brighten the interior, while sloped windows help keep excessive heat out during warmer days. High windows above the central area promote natural airflow, creating a comfortable atmosphere inside. Each room is designed for flexibility, allowing spaces such as the bedroom to transform into an area for yoga or a living area to serve as a workspace.

Sustainability Features
Sustainability is a central theme in this design. The roof terrace features a vertical garden for growing food, enhancing the self-sufficiency of the home. Additionally, rainwater collection systems are strategically placed to capture runoff, allowing for efficient water use and conservation.

Materials
The materials chosen for the microhome focus on sustainability and energy efficiency. Engineered bamboo products are used for the structure, providing both strength and environmental benefits. Sheep wool serves as insulation, helping meet energy performance standards. This selection of materials aims to create a low-impact living environment.

The CACATOO LODGE illustrates the potential of living in smaller spaces, blending comfort with practicality. The careful combination of adaptable areas and environmentally friendly features results in a home that encourages a strong relationship with the outdoors.

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.
