Incorporating a water harvesting cistern within its concrete foundations and employing tiered platforms for efficient space utilization, this compact home addresses the challenges of sustainable living in South Australia's arid climate.
5 key facts about this project
01
Incorporates a rainwater harvesting cistern within the foundation.
02
Utilizes tiered platforms to optimize vertical space and eliminate stairs.
03
Designed to function efficiently within a 25-square-meter footprint.
04

05
Features storage solutions integrated into the tiered platform structure.

'Tiered & Tiny' is located in South Australia, designed to address the challenges posed by a hot and dry climate. With a compact footprint of 25 square meters, it provides a home for a young couple and their dog. The overall design maximizes vertical space and integrates practical solutions aimed at sustainability.

Water Harvesting System

The project includes a water harvesting cistern incorporated into the foundations of the house. This element collects rainwater and eliminates the need for separate storage tanks. By combining functionality and structural support, the cistern directly addresses the reactive soil conditions found in the region.

Spatial Optimization

To utilize every inch of space, the design employs tiered platforms. This method removes the need for traditional staircases, allowing for better movement within the home. Storage areas are found beneath these platforms, ensuring that all essential amenities remain accessible. The arrangement enhances the overall utility of the living spaces and encourages a comfortable, organized environment.

Sustainable Energy Integration

An effective energy strategy is a crucial aspect of the design. A solar panel and battery system were included to meet the home's energy needs. This choice reflects a dedication to using renewable resources, creating opportunities for more sustainable living. The integration of these systems demonstrates a thoughtful approach to managing energy within a limited footprint.

The tiered arrangement not only offers practical solutions but also creates a distinct look. Clear separations between levels and connections to both indoor and outdoor spaces enrich the living experience. This approach shapes a thoughtful response to the local climate, emphasizing both comfort and sustainability.

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.
