Located on a tectonic crack between two continental plates.
02
Observation platform elevates visitors to 18 meters for expansive views.
03
Design embodies themes of imperfection and Wabi-Sabi philosophy.
04
Pathways constructed from durable concrete slabs link key features.
05
Functional annex includes a café, enhancing visitor engagement.

The Cracked Tower is located in a dramatic landscape defined by the Grjotagja caves, situated on a tectonic crack between the American and Eurasian continental plates. The design invites visitors to engage with the surrounding geological features while exploring themes of imperfection. Inspired by Leonard Cohen’s reflections on the beauty of flaws, the structure serves both as an observation point and a functional space for visitors.

Design Concept

The design takes a straightforward geometric form that connects with the natural characteristics of the site. This approach allows the structure to sit comfortably within its rugged environment while also reflecting the themes of imperfection. The tower’s shape echoes the crack in the landscape, creating a relationship with the environment and enhancing the experience for visitors who interact with the geology of the area.

Functionality and User Experience

The tower includes an annex that serves multiple purposes. There is a café and an information center designed to inform and accommodate visitors. Facilities such as restrooms are provided for convenience. An observation platform, positioned at a height of around 18 meters, offers views of the striking landscape and geological formations. It encourages visitors to connect with their surroundings in an intimate way.

Materiality

The project uses concrete for the tower’s skin and pathways, reinforcing its relationship with the volcanic rock found in the landscape. The structure is supported by a steel frame, which allows for prefabricated components that simplify construction. Prefabricated concrete slabs are used for the façades and the foundation, ensuring that the assembly process is efficient and minimizes the environmental impact.

Accessibility and Pathway Design

Well-defined pathways connect the tower to key natural features, such as the caves, allowing visitors to explore the area easily. These pathways, built from concrete slabs, ensure a straightforward way to navigate the terrain while enhancing the overall experience of visiting the site.

The observation platform provides panoramic views that highlight the unique geological formations, reinforcing the connection between the tower and the natural 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.
