With a focus on geothermal energy and a structure defined by an ETFE membrane and local timber, this building serves as a community hub that enhances visitor engagement while harmonizing with the unique geological landscape.
5 key facts about this project
01
ETFE membrane enhances visibility and natural light while maintaining energy efficiency.
02
Local timber complements the building’s structure and reduces carbon emissions from transport.
03
Geothermal energy system provides both heating and electricity for sustainable operation.
04
Water collection system efficiently recycles rainwater and snow for reuse throughout the facility.
05
The building’s design emphasizes community engagement and interaction with the natural landscape.

"The Mouth of A Spring" is an architectural design that showcases the relationship between natural features and built environments. Located on the boundary between the Eurasian and North American tectonic plates, it serves as both a landmark and a community hub. The design is inspired by the idea of a hot spring, which influences its form and structure. The project emphasizes a connection to the natural world and seeks to create a vibrant space for visitors.

Conceptual Framework

The design concept revolves around the metaphor of a spring. This is reflected in the building's shape, which suggests movement and emergence from the ground. The structure is divided into east and west sections, characterized by glass facades that provide a clear view and help illuminate the interior. Different colors in the membrane structures symbolize the geographical divide, enriching the visual experience and guiding people through the space.

Spatial Organization

Open social spaces are central to the layout, encouraging interaction among visitors. High ceilings and expansive areas allow natural light to flood these spaces, making them feel bright and welcoming. The use of ETFE membrane technology on the exterior permits light to penetrate while creating a connection with the surrounding landscape. This arrangement fosters a community atmosphere, making it a suitable venue for different gatherings.

Sustainability Initiatives

Sustainability plays a significant role in the building's function. A geothermal energy system is in place to harness underground heat, supplying electricity and hot water. This makes the design not only efficient but also environmentally friendly. The project captures rainwater and melting snow through a water collection system, filtering it for reuse. These practices contribute to minimizing the environmental impact of the building.

Material Selection

Local timber is used for the main and internal structures, supporting sustainability by reducing transportation emissions. This choice also strengthens the building's connection to its natural surroundings. The external ETFE membranes add another layer of functionality, offering both insulation and transparency. They help regulate temperature while allowing visibility to and from the outdoors.

The design culminates in a narrative that reflects the spirit of the natural spring. It fosters engagement between users and the landscape, creating an environment where architecture and nature coexist harmoniously.

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
