**Overview**
Mývatn Refuge is located in the Mývatn region of Iceland, characterized by its striking volcanic landscape and ecological diversity. The design intention is to provide a functional space that serves both human visitors and local wildlife while incorporating environmentally sensitive solutions. Positioned near Lake Mývatn and the Krafla Caldera, the structure aims to foster outdoor engagement and promote a deeper connection with the surrounding natural environment, including views of the Aurora Borealis.

**Architectural Strategy**
The spatial organization of the refuge prioritizes accessibility and interaction, featuring a central rest area that functions as a communal hub for visitors. The layout includes essential facilities such as a garage, storage areas, and an observation deck that enhances the overall user experience within the context of various outdoor activities. Garden pockets integrated into the site not only beautify the landscape, but also utilize graywater for irrigation, reflecting the commitment to sustainability and regenerative practices.

**Material Selection and Environmental Integration**
The building employs a range of materials specifically chosen for their environmental adaptability and aesthetic qualities. Glass Reinforced Concrete (GRC) forms the exterior shell, allowing for organic shapes that reflect the surrounding geology, while galvanized steel studs ensure structural resilience against the region's harsh weather conditions. Interior finishes are designed to provide warmth, counterbalancing the cooler external climate. Innovations include a graywater management system drawn from local ecological patterns, promoting a closed-loop method for water use that benefits the surrounding 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.
