Rising thirty meters, the tower constructed from engineered wood serves as a landmark, guiding visitors along hexagonal pathways to explore nearby caves while emphasizing geothermal sustainability.
5 key facts about this project
01
Rising thirty meters, the tower serves as a landmark for navigation.
02
Statues of a Bull and Canadian Moose represent cultural connections to the continents.
03
Hexagonal pathways made from volcanic ash enhance durability and aesthetics.
04
A Stirling engine generator provides electricity using geothermal heat.
05
Wastewater from the coffee shop is repurposed for irrigation.

The design features a tower inspired by ancient Viking boats, prominently positioned to act as a beacon in the landscape. Standing at thirty meters high, the structure directs visitors toward various attractions, including caves nearby. A pathway made from hexagonal volcanic ash pavers enhances the experience, providing a durable and visually suitable link to the natural setting.

Design Features

At the entrance, statues represent the continents of North America and Europe. A Bull symbolizes Europe, while a Canadian Moose represents North America. These figures make visitors think about the geographical and cultural connections between the continents. As people approach the tower, these elements encourage a deeper engagement with the site’s themes.

Functional Spaces

The design incorporates spaces that prioritize accessibility. A coffee shop serves as a place for visitors to rest and enjoy refreshments while taking in the landscape. An optional exterior lift provides access to both the coffee shop and the observation deck, ensuring comfort for all visitors. For those with mobility challenges, service in the lobby is easy to navigate and designed with a ramp.

Sustainability Features

Sustainability is a key consideration in the design’s operation. A Stirling engine generator, located on the ground floor, utilizes geothermal heat and ambient temperature to generate electricity. Water is drawn from boreholes and filtered for safety. Wastewater management is also considered; used water from the coffee shop is collected for irrigation, while black water is redirected to a septic system for processing.

Materials and Construction

The structure uses engineered wooden beams for its framework, allowing for straightforward assembly and quality control. This method speeds up construction while maintaining standards. Corrugated steel serves as the cladding, chosen for its strength and resistance to the local climate, requiring little maintenance. The design language reflects a focus on functionality and respect for the surrounding environment, resulting in a building that interacts well with its setting.

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.
