Utilizing geothermal energy, a galvanized steel footbridge elegantly spans the volcanic landscape, providing accessible viewpoints for visitors to engage with the unique geological features of the Nemrut Caldera.
5 key facts about this project
01
Utilizes geothermal energy for sustainable electricity generation.
02
Features galvanized steel mesh for visibility and safety.
03
Designed with a 5% slope for universal accessibility.
04
Integrates seamless observation decks that enhance landscape engagement.
05
Constructed to withstand harsh weather conditions in a volcanic environment.

### Project Overview
The Nemrut Volcano Observation Footbridge is situated within the Nemrut Caldera in Eastern Turkey. Designed to enhance visitor engagement with the region’s unique volcanic landscape, the structure offers expansive views of Lake Van and the surrounding terrain. The architecture integrates effectively with the natural environment, reflecting a commitment to sustainable practices, including the use of geothermal energy.

### Spatial Strategy and Visitor Engagement
The design prioritizes accessibility and visitor interaction, featuring a 5% inclined ramp that leads to three strategically positioned observation decks. These platforms provide uninterrupted vistas of the caldera, facilitating an immersive experience that connects visitors to the geological and environmental characteristics of the area. The architectural language is defined by smooth, flowing lines that echo the region’s natural forms, minimizing visual disruption while fortifying the relationship between the structure and its landscape.

### Materiality and Sustainable Systems
Constructed primarily from galvanized steel, the footbridge is built to withstand the harsh climatic conditions typical of the area while maintaining aesthetic coherence with the environment. Key materials include a galvanized steel mesh walking surface designed for safety and visibility, complemented by a variety of structural components such as steel I-columns and welded column heads.

The project incorporates geothermal energy systems that leverage the volcanic activity beneath the surface, providing electricity for the footbridge and the nearby cableway system. Additional sustainable features include integrated lighting for safety during nighttime use and a heat-based snow management system, ensuring year-round access. This approach underscores a commitment to renewable energy and environmental stewardship.

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.
