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.

The Next House: USA — A Global Call to Reimagine the American Suburb

`
Competition organisers

Buildner is launching The Next House: USA, a global architecture competition that challenges architects, designers, and thinkers to reimagine the American suburban home for the 21st century. For decades, the suburban house has symbolized comfort and stability, but today it often reflects excess, isolation, and environmental strain. This competition asks: how can the American home evolve to address climate urgency, economic pressures, and shifting social values?

Participants are tasked with designing a prototype home of no more than 1,500 sq ft (≈140 m²) for a household of two adults and one child. The design should be compact yet generous, adaptable, sustainable, affordable, and replicable across diverse U.S. contexts. More than a design exercise, the competition aims to spark a conversation about how homes can support healthier, smarter, and more connected communities.

The total prize fund is $20,000 USD. The final registration deadline is May 20, 2026, and winners will be announced on September 22, 2026. The Next House: USA invites architects, students, and visionaries worldwide to redefine what the American home means today—and what it should mean tomorrow.
