Utilizing a unique integration of rain catchment systems and microhomes, this supportive housing initiative provides a sustainable solution for addressing homelessness in Vancouver.
5 key facts about this project
01
Microhomes allow flexibility for residents to relocate as needed.
02
PUPA, ECLOSION, and BUTTERFLY phases guide the transition to independence.
03
Rain catchment systems provide sustainable water resources for residents.
04
Solar water heaters reduce utility costs for long-term living.
05
Active community engagement fosters social ties and support networks.

The CHRYSALIS housing project is located in Vancouver, Canada. It provides a structured approach to addressing the issue of homelessness. The design is based on the natural process of a caterpillar transforming into a butterfly. This concept reflects a journey from a state of vulnerability to one of independence and stability. The project is divided into three phases: PUPA, ECLOSION, and BUTTERFLY, each representing a step in the path toward self-sufficiency.

PUPA is the first phase, offering transitional housing for individuals experiencing homelessness. This stage ensures easy access to important services that promote employment and community participation. The design focuses on creating a supportive environment. It is arranged in a way that enhances functionality while helping residents to recover and regain their independence.

Once individuals reach the ECLOSION phase, they begin to earn personal income. At this stage, occupants start making low rental payments, which encourages them to take an active role in managing their finances. The design of this phase emphasizes flexibility. Spaces can adapt to the evolving needs of the residents, providing a practical solution for various life circumstances.

In the BUTTERFLY phase, residents achieve homeownership within government-managed plots designated for long-term development. This stage allows residents more freedom, as they can move their homes to different locations if needed. Such mobility ensures that residents are not confined by fixed structures, enhancing their quality of life in the urban setting.

Sustainability is an integral aspect of CHRYSALIS. Features like rain catchment systems and solar water heaters contribute to a lower cost of living for residents. Solar panels harness renewable energy that can be used or sold back to the grid, promoting environmental responsibility. The design allows for a reduced ecological footprint, ensuring that the living environment is not only functional but also responsible.

The CHRYSALIS project beautifully combines support and sustainability. The design encourages residents to innovate in their use of resources. This focus on integration fosters a sense of community ownership, allowing individuals to move from reliance on support systems to independent living. Each detail contributes to a supportive and sustainable living environment, making it a thoughtful solution to complex social challenges.

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.
