Subscribers only
Corten steel structures create a series of framed viewpoints within a rugged volcanic landscape, inviting visitors to engage with the geological features while providing an educational space for exploration.
5 key facts about this project
01
Corten steel weathering was intentionally selected to blend with the volcanic landscape over time.
02
The design features multiple framed perspectives that encourage a deeper exploration of the surrounding environment.
03
Pathways are integrated with the natural slope, emphasizing ecological sensitivity in site development.
04
Educational components focus on the geological context, enhancing visitor engagement with local features.
05
Structures are constructed to adapt to the site’s rugged terrain, minimizing disruption to the natural ecosystem.

### Project Overview
Located near Lake Van in Turkey, specifically in the Nemrut Volcano area, the design addresses the unique characteristics of a volcanic landscape where rugged terrain meets tranquil waters. The intent is to establish an observational platform that enhances visitors’ connection to the surrounding environment while providing an interactive space for nature exploration.

### Spatial Strategy
The design employs framed structures that guide visitors’ perspectives and encourage exploration of the natural surroundings. The orientation of various rectangular elements leads the eye toward specific vistas, fostering an immersive experience that highlights the region's geological features. Pathways and steps are designed to integrate with the natural contours, facilitating movement and exploration while enhancing the relationship between constructed spaces and the environment. The thoughtful placement of these elements also informs visitors of proximity to steep cliff edges, enriching their engagement with the dramatic topography.

### Materiality and Sustainability
The project primarily utilizes corten steel for its external structures, chosen for its durability and rust-like appearance that blends with the landscape. This material undergoes a natural weathering process that allows it to evolve aesthetically while requiring minimal maintenance. Reinforced concrete is employed for structural stability, complemented by specific treatments to enhance weather resistance and visual harmony within the environment. The design emphasizes sustainability through material choices and the integration of structures that respect the ecological integrity of the site, ensuring long-term coexistence with the 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.
