## Architectural Design Report: Matchbox

### Overview
Matchbox is a modular housing solution developed to address urgent needs for affordable and sustainable living spaces, particularly in emergency and crisis situations. Designed for rapid deployment, this project integrates flexible, transportable microhomes that focus on community integration while utilizing eco-friendly materials and construction techniques.

### Modular Structure and Scalability
The Matchbox units consist of prefabricated modules measuring 2.5 x 5 x 1 meters, allowing for a variety of living configurations suitable for different family sizes or communal arrangements. The use of a modular design facilitates efficient assembly and disassembly, promoting adaptability to varying site conditions. The system's scalable nature supports configurations from single units to larger community settings, effectively responding to the needs of occupants in diverse contexts.

### Sustainable Materiality
Key structural components include lightweight and durable cardboard tubes, treated to ensure a lifespan of up to twenty years, and rigid metal frames that provide structural integrity and resilience against environmental conditions. The homes are further enhanced by waterproof bio-based epoxy coatings that contribute to their longevity. Sustainable features such as off-grid solar power systems and rainwater harvesting capabilities reduce reliance on external resources. Thermal efficiency is achieved through multiple layers of insulation made from environmentally friendly materials, ensuring comfort and minimizing ecological impact.

This design approach not only addresses immediate housing needs but also prioritizes sustainability and user responsiveness in its execution.

Vancouver Tall Challenge: Building Higher Downtown

`
Competition organisers

The Vancouver Tall Challenge: Building Higher Downtown is an international architecture competition organized by Buildner in collaboration with the City of Vancouver and the University of British Columbia’s School of Architecture and Landscape Architecture (SALA). The competition invites architects, designers, planners, and creative thinkers to explore innovative approaches to tall buildings in Vancouver’s downtown core, focusing on sustainability, livability, urban density, public space, and the city’s strong connection to nature. As Vancouver continues to grow, participants are challenged to rethink how vertical development can enhance urban life and contribute to a more vibrant, inclusive, and resilient city identity.

The competition offers a total prize fund of $15,000 CAD, with winning proposals selected by an international jury of architects, planners, academics, and city-building professionals. Key dates include the final registration deadline on October 29, 2026, submission deadline on November 30, 2026, and winners announcement on January 26, 2027.
