Incorporating geothermal piping and a façade of lava rock, this structure seamlessly combines hydroponic food production with a restaurant, enhancing sustainability within Iceland's unique landscape.
5 key facts about this project
01
Utilizes recycled geothermal piping inspired by local volcanic rock.
02
Features a glass façade to maximize solar heat gain for plant growth.
03
Integrates extensive hydroponic systems for on-site food production.
04
Designed with two distinct elements: a vertical tower and horizontal extensions.
05
Incorporates ground-source heat pumps for energy-efficient climate control.

The Iceland Greenhouse Restaurant is situated in an area defined by black lava rock. It serves as both a dining venue and a greenhouse, creating a blend of two functions into one cohesive design. The focus on sustainability and food cultivation drives the architectural concept, leading to a thoughtful relationship between the structure and its natural surroundings.

Design Concept

The layout of the building features a linear arrangement that extends across the landscape. This design approach brings together vertical and horizontal forms, creating a balance between the natural terrain and the constructed environment. The building’s low profile respects the local geography, allowing it to coexist with the land rather than dominating it.



Structural Components

Structural elements reference geothermal pipes found throughout Iceland. This connection to the local infrastructure emphasizes the use of regional resources. The project also incorporates recycled geothermal piping, reflecting the hues of the surrounding volcanic rock. This choice supports both environmental sustainability and a sense of place within the architectural design.



Functional Integration

A notable feature of the restaurant is its integration of hydroponic systems, allowing for food production within the space. The glass façade increases solar heat gain, creating optimal conditions for plant growth while offering views of the exterior. Inside, the design organizes various functions that flow from one area to another, from exhibition spaces on the ground floor to dining areas and greenhouse activities on upper levels.



Environmental Considerations

Ground-source heat pumps are employed for heating and hot water, utilizing the geothermal energy available in Iceland. This technology highlights a commitment to sustainability in the design, allowing the building to operate efficiently and with a reduced impact on the environment. The integration of these systems illustrates a practical approach to contemporary architectural needs.



The design culminates in expansive roof decks that provide wide views of the surrounding landscape. These areas enhance the experience for those who use the space, fostering engagement and interaction within the community.

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.
