The Iceland Cave Tower is located at the Grjótagjá Cave in Iceland, designed to fit within the rugged landscape. The project aims to enhance the experience for visitors by providing a place to engage with the remarkable geological features of the area. It includes a viewing tower, a Visitor Center, and a Landscape Hotel, all of which work together to create a thoughtful interaction with the surrounding nature.

Viewing Tower

The viewing tower serves as a central feature of the design, leaning over a tectonic crevice that showcases the geological context of the site. It consists of three cubic volumes, with two directing attention towards the crevice and one positioned in the opposite direction. This layout allows for captivating views of the landscape while connecting the structures to the vast Icelandic terrain.

Visitor Center

The Visitor Center is purposely distinct from the tower, aiming to provide essential services while ensuring uninterrupted access to the site. It includes changing rooms and bicycle rental options, acting as a hub for visitors. Its strategic location, situated between the entrances to the Men’s and Women’s Caves, makes it easy for people to explore the area's geological features and fosters a deeper connection with the environment.

Landscape Hotel

The Landscape Hotel adds another layer to the visitor experience. Accommodating ten guests, the hotel prioritizes privacy within the open landscape. It features communal areas such as a bar and restaurant available to the public, along with an event room suitable for gatherings. These spaces encourage social interaction while maintaining an appropriate balance with the surrounding nature.

Material Usage

The buildings utilize locally sourced materials, including basalt, granite, and diorite. These natural stones emphasize the relationship between the structures and the Icelandic landscape, both in appearance and texture. The incorporation of these materials not only strengthens the designs but also resonates with the geological identity of the region.

Large landscape windows frame stunning vistas, allowing guests to immerse themselves in the beauty of Iceland’s environment. This design element creates a strong connection between the visitors and the natural world, enhancing the overall experience of being in this unique setting.

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.
