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.

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
