Cracks in a Corten steel exterior reveal an architectural valley leading to geothermal access, merging natural fissures with the structure's function as a visitor center and viewing tower.
5 key facts about this project
01
Cracks in the structure reveal different materials to symbolize warmth within the visitor center.
02
The entrance is designed as an architectural valley, guiding visitors toward geothermal springs.
03
Corten steel develops a weathered patina, enhancing integration with the natural landscape.
04
The monolith's incomplete design invites contemplation about environmental fragility.
05
Light filters through the cracks, creating dynamic shadow patterns inside the space.

The Tectonic Monolith provides a striking engagement with its geological setting. Located in an area known for geothermal hot springs, the design draws inspiration from tectonic plates, presenting a form that is broken but cohesive. As a combination of a viewing tower and a visitor center, it enhances the experience of the surrounding landscape while focusing attention on the delicate balance of nature. The concept emphasizes how built structures can harmonize with their natural environments.

Spatial Configuration

The entrance is located within an architectural valley that directs visitors toward the geothermal features. This configuration transforms entry into an experience, guiding people from the outdoor landscape into the comforting interior of the building. The pathways invite exploration, making it easy for visitors to engage with their surroundings while moving toward the warm heart of the structure.

Material Expression

Timber and Corten steel are vital to the building's visual character. Timber provides an organic warmth that contrasts with Corten steel, known for its rugged and weathered finish. The stark materials are thoughtfully chosen; together, they create a dialogue between human construction and the elements. Over time, the Corten steel develops a rich patina, further aligning the structure with the geological environment that surrounds it.

Design Interpretation

The monolith’s cracked form serves to highlight themes of incompleteness and change. This design choice sparks thoughts about the ongoing processes found in nature. The structure appears as if it is still evolving. Cracks at the pinnacle enhance this idea, prompting visitors to consider their relationship with the environment. It also invites contemplation about the necessity of caring for the natural world.

Inward Reflection

Light and shadow play significant roles within the Tectonic Monolith. As natural light filters through the cracks, it creates varying atmospheres that change throughout the day. This interaction not only showcases the textural qualities of the materials but also enhances the sensory experience for those inside. Such details deepen the connection between architecture and landscape, immersing visitors in a thoughtful journey through space and time.

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.
