### Overview

Located in a densely populated urban context, the TreeHive project proposes a unique residential model while prioritizing sustainability and community engagement. The design integrates communal spaces alongside individual living units, aiming to enhance the quality of life for residents and address the challenges posed by a demand for affordable housing.

### Spatial Modularity and Growth

Central to the design is the principle of "grow-as-you-need," which accommodates changing demographics and evolving community needs. The structure features a tree-like form that supports vertical expansion through a modular system, allowing the addition of living spaces and communal areas over time. This approach not only addresses immediate housing needs but also ensures adaptability in response to shifting population dynamics. Triangular platforms provide stability while facilitating interaction among residents, allowing for the seamless integration of shared amenities, such as parks and community centers, into the overall living environment.

### Sustainable Materiality

The project's material selection focuses on resilience and environmental sustainability. Key materials include cross-laminated timber (CLT) for structural warmth and sustainability, steel trusses for load distribution, and concrete for foundational stability. Large expanses of glass enhance natural light and create visual connections with the outdoor environment. Additionally, green roof systems support biodiversity, contributing to the building's ecological footprint. These materials are carefully chosen to reinforce the project's commitment to fostering a connection between residents and their natural surroundings while promoting overall well-being within the urban landscape.

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.
