ETFE Membrane Structure Merging With Local Timber And Community Engagement

Project in-detail

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 MICROHOME 10 competition invites participants to submit visionary designs for off-grid, modular microhomes that push the limits of sustainable, small-scale living. Organised by Buildner in partnership with Kingspan and Hapi Homes, this tenth edition sets the challenge of designing a dwelling for two people within a maximum floor area of 25 m², encouraging bold solutions adaptable to any urban or rural location. The competition continues Buildner’s mission to foster innovative approaches to compact, energy-efficient housing that can address pressing global challenges.

This year’s edition offers a generous total prize fund of €100,000, including the Kingspan Award for designs that integrate high-performance Kingspan products and the Hapi Homes Award for a project selected for real-world construction. In addition to cash prizes, the winners gain international exposure through Buildner’s media partnerships, publications, and a dedicated MICROHOME magazine, further amplifying their ideas to the wider architectural community.

Key dates for MICROHOME 10 include the closing date for registration on 25 September 2025, the submission deadline on 29 October 2025 (11:59 p.m. London time), and the announcement of winners on 9 December 2025. These milestones ensure participants have clear timelines to develop and present their concepts, with early registration discounts available to support students and emerging designers worldwide.
