5 key facts about this project
01

The design is located in Iceland and interacts thoughtfully with the striking volcanic landscape. It includes three main areas: a viewing tower, a café, and a waiting area. The overall design concept emphasizes the connection between the built environment and nature. The structure serves not only functional purposes but also aims to enhance the experience visitors have with the dramatic scenery around them.

Design Intent

The architecture highlights a relationship between forms and the surrounding land, presenting various roof shapes that intersect and unite the space beneath. The viewing tower stands out, acting as a landmark that draws attention to the region's geological features. It helps visitors understand the landscape's history and significance. The design is not just about aesthetics; it also serves an educational purpose that connects visitors to the site.

Spatial Organization

Different areas of the design are carefully arranged to encourage movement and interaction. Visitors navigate through the tower, café, and waiting area, with each space providing a unique perspective on the surroundings. Pathways guide the flow of traffic, inviting exploration and ensuring that the journey and destination are equally important. This thoughtful layout creates an engaging way for visitors to experience the shifting landscape.

Material Considerations

Materials used in the design play an important role in connecting the structure to its geographical context. Pozzolana cement, made from volcanic ash, is a significant choice, reflecting the local environment. This selection promotes sustainability and aligns with the surrounding land characteristics. Low-impact construction methods are also evident, allowing for minimal disruption to the area. The choice of materials supports durability while fostering a deeper connection to the site.

Design Detail

An interesting aspect of the café is its entrance, designed to showcase the natural rock surface as part of the overall design. Large windows allow light to enter and illuminate the texture of the rock, extending the outdoor views into the interior space. This connection emphasizes the relationship between inside and outside, making visitors feel immersed in the natural setting as they move through different areas.

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.
