Defined by its circular layout and integrated wood louvers for effective natural ventilation, the design creates a shared living environment that fosters community resilience and sustainability.
5 key facts about this project
01
Circular layout enhances social interaction among residents.
02
Integrated wood louvers reduce solar gain while allowing natural light.
03
Central cooling core utilizes water for passive ventilation.
04
Vegetation creates microclimates for outdoor comfort.
05
Shared communal spaces foster a sense of community and belonging.

The co-housing design addresses the growing social and economic challenges faced by various groups, particularly amid increasing living costs and social disconnection. Located near the Yarra River, the design emphasizes a modern approach to communal living, drawing inspiration from traditional cohabitation practices. A circular layout facilitates connection among residents while preserving the necessary privacy.

Design Concept

At the heart of the design is a circular arrangement that promotes community engagement. The dwelling units are positioned around shared communal areas, allowing for interaction among residents. By incorporating facilities such as communal kitchens, dining spaces, and terraces, the design fosters a strong sense of belonging while also reducing operational costs.

Sustainability Measures

Sustainability is central to the design. Passive energy management strategies are employed to enhance efficiency. A central core acts as a cooling tower, utilizing a small amount of water to assist in natural ventilation. Residents have control over airflow through operable openings, increasing comfort within their homes. The thoughtful placement of vertical wood louvers helps reduce unwanted solar gain while letting sufficient natural light in.

Vegetation and Microclimate

Vegetation is integrated into the overall design, serving both aesthetic and functional purposes. The landscaping creates cooler outdoor environments while supporting local biodiversity. These green spaces contribute to pleasant communal areas, facilitating a closer connection to nature for residents. This approach not only enhances the environment but also increases the comfort and livability of the setting.

Circulation Strategy

Central circulation elements, such as stairs and elevators, are situated in the building's unconditioned core. This arrangement lowers energy use in spaces that are not frequently visited. The design allows for straightforward movement throughout the structure while reinforcing the communal atmosphere.

The circular layout expertly combines social interaction and individual needs, promoting a new vision of communal living that reflects contemporary values.

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.
