The integration of volcanic rock into a partially underground structure enhances energy efficiency while providing visitors with expansive views of the surrounding landscape, serving as a functional hub for exploration and relaxation.
5 key facts about this project
01
Main structure is partially submerged to minimize environmental impact.
02
Interior features walls lined with volcanic rock for a tactile connection to the landscape.
03
Dome shape adapts to various functional zones within the visitor center.
04
Constructed with energy-efficient earth-sheltered design leveraging stable soil temperatures.
05
Designed to provide unobstructed views of the nearby volcano from all interior spaces.

The Volcano Coffee Shop is located in the volcanic landscape of Iceland, serving as a central hub for hikers and visitors. The design aims to blend with the natural environment, minimizing visual and physical disruption to the area. By placing much of the building underground, it respects the geological integrity of the site while fulfilling its function.

Architectural Organization

The design is divided into functional zones that cater to the needs of different visitors. Each zone is distinct yet encourages interaction among users involved in various activities. The intent is to create an engaging experience that enhances the connection to the volcanic landscape. Clear pathways have been laid out to ensure smooth movement between exhibition areas, consultation spaces, and visitor services.

Spatial Dynamics and Form

A key aspect of the Volcano Coffee Shop is its dome space, which adapts to the specific functions within the building. This flexibility allows for different scales and activities without conflicts between them. The architectural form features varying heights, which enhances visibility and contributes to the overall spatial experience.

Materiality and Energy Efficiency

The main materials include formwork concrete for the walls and volcanic rock for the interiors, reflecting the local environment. This choice reinforces the connection to the surrounding landscape and enhances the building's character. Additionally, the earth-sheltered design improves energy efficiency by utilizing the stable temperature of the soil, which helps reduce heating needs and lower long-term costs.

Natural Light Interaction

Strategic openings throughout the building provide views of the nearby volcano, creating a connection between the interior and exterior. This design consideration not only allows natural light to fill the space but also enhances the visitor experience. The natural scenery becomes a part of the journey, emphasizing the tactile qualities of the materials used and creating an inviting atmosphere.

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.
