5 key facts about this project
01
Curved openings echo the natural landscape, enhancing views and light.
02
Basalt laywork is used in the geothermal trap for efficient heating.
03
Local geosprings provide the primary source of thermal energy.
04
Individual rooms are designed to reflect traditional Icelandic architecture.
05
The layout promotes a seamless flow between communal and private spaces.

The "Thermae" project is located in the captivating landscapes of Iceland, designed to offer a unique luxury hospitality experience that connects closely to the surrounding environment. The design draws inspiration from Iceland's diverse geography. It uses modern architectural elements while referencing traditional Icelandic styles. Curved openings and detached structures create individual rooms. These features reflect historical influences, enhancing the overall guest experience.

Heating Strategy

A geothermal heating strategy is central to the design. It takes advantage of natural geosprings located just a few kilometers away from the site. By using local resources, the system provides effective temperature control for the interiors. The underfloor design includes a geothermal trap made with layers of concrete and rough basalt. This construction allows heat to be gradually released into the spaces, promoting comfort while meeting environmental goals.

Architectural Layout

The layout of the "Thermae" project encourages a natural flow between shared spaces and private rooms. Carefully arranged spaces create views that frame the beautiful landscape outside. This design blurs the lines between indoor and outdoor environments, enhancing guests' connection to nature. Individual rooms are designed to provide personal comfort while appreciating the beauty of Iceland.

Materiality

Materials chosen for the "Thermae" project support both aesthetics and functionality. The list includes 20mm marble plate tiling, 5mm epoxy self-leveling mortar, and layers of concrete and lime mortar. Each material is selected for its durability and ability to withstand Iceland's challenging climate. Together, they contribute to thermal efficiency and establish a clear visual identity throughout the building.

The exterior features a roof design that reflects the natural terrain. Each room offers unobstructed views of the stunning landscape. The design not only promotes luxury but also allows guests to engage fully with the remarkable Icelandic scenery, creating an intimate atmosphere that aligns with the natural surroundings.

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.
