5 key facts about this project
01
Cantilevered concrete beams create an open central area without columns.
02
A green roof enhances biodiversity and connects occupants with nature.
03
Private zones include a drop-in area for recycling without building access.
04
Skylights allow natural light to illuminate the interior spaces.
05
Design emphasizes community engagement through multifunctional spaces.

The architectural design known as "FRÁ JÖRÐUNNI" is set in an urban environment and functions as a community hub. The design concept focuses on an almost column-free structure that promotes openness and connectivity within the space. By framing a central area for community use, the building encourages social interaction and highlights its relationship with the surrounding landscape.

Structural Framework

Concrete concourse beams form the primary structural system, extending from the foundation and cantilevering the roof. This approach allows the building to appear as if it is emerging from the ground. The absence of columns in the central space enhances the feeling of openness, creating an environment where movement and interaction can take place freely.

Functional Layout

The heart of the design is an open area dedicated to various community activities. This space connects essential components such as an open kitchen, a fabrication lab, a resource exchange, a recycling area, a kids’ area, and an information desk. By linking these functions, the design promotes engagement and supports the building's role as a center for social gathering and collaboration.

Private Zones

Adjacent to the central area are private zones, including a sauna/showers and a depot, which are designed to cater to individual needs while remaining accessible. The depot includes a drop-in area for visitors to deposit recycling items and resources, which enhances efficiency. This thoughtful arrangement of spaces balances the need for public engagement with the importance of personal privacy.

Green Integration

Sustainability plays a key role in the design, exemplified by the greenhouse located on the second level. This feature creates a connection to the green roof, allowing users to engage with nature. The green roof not only adds to the visual appeal of the structure but also supports biodiversity and promotes ecological awareness within the community. The design integrates the built environment with the natural landscape, creating a harmonious relationship between the two.

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.
