Constructed with local stone and earth, the design creates circular communal spaces that harmonize with the natural landscape while fostering sustainable living.
5 key facts about this project
01
Constructed primarily from local stone and soil, enhancing regional sustainability.
02
Circular layout promotes communal interaction and connectivity among residents.
03
Design incorporates natural ventilation strategies for energy efficiency.
04
Adaptation of ancient building techniques creates a modern interpretation of prehistoric shelters.
05
Integrated vegetation around the structure fosters biodiversity and ecological awareness.

### Overview
Located in a region rich in historical and natural significance, the project examines the interplay between human habitats and their environment, inspired by prehistoric dwelling techniques. The intent is to create spaces that foster emotional connections to nature while paying homage to ancestral living. By employing locally sourced materials and integrating natural elements, the design reflects a commitment to environmental stewardship and communal living.

### Spatial Configuration
The layout features a circular design that encourages inclusivity and interaction among users. Central gathering areas are surrounded by partitions that evoke the characteristics of primitive enclosures, facilitating a sense of community. Gentle elevations and depressions within the site mimic natural topography, allowing for a harmonious relationship with the landscape. Architectural strategies prioritize natural ventilation and light, enhancing energy efficiency while providing comfort. Vegetation surrounding the structure supports both aesthetic values and functional benefits, such as shade and air purification.

### Material Selection
The material palette is derived entirely from the surrounding environment, emphasizing sustainability and locality. Key materials include rock, pebbles, sand, soil, clay, and glass—each carefully selected for their durability and relevance to the local context. This approach not only strengthens the project's sustainability ethos but also underscores a commitment to integrating a circular economy into construction practices. Additionally, the use of glass sourced from local sand helps facilitate natural lighting and visual connections to the exterior environment, reinforcing the design's focus on blending indoor and outdoor spaces.

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.
