Building Above a Tectonic Fault with Catenary and Truss Systems

Project in-detail

Built above a tectonic fault, this crossing structure utilizes catenary and truss systems to minimize its footprint while creating engaging spaces for community interaction and exploration.
5 key facts about this project
01
The majority of the program is situated above a tectonic fault line.
02
The structure employs a combination of catenary and truss systems for structural integrity.
03
The design features both a central tower and a cave-like programmatic space.
04
Roofing elements are intentionally disconnected from the main tower.
05
Strategic layouts enhance user engagement with the surrounding landscape.

"On the Giant's Shoulders" is located in Iceland and showcases a thoughtful approach to integrating architecture with the natural landscape. The design aims to preserve the existing environment while providing spaces for the community to gather and explore. The concept centers on minimizing architectural impact, allowing the building to coexist harmoniously with its surroundings.

Structural Concept

The design features a “crossing building” framework that employs a catenary and truss system. This system allows for an innovative foundation that partially connects with the ground. As a result, the structure maintains a smaller footprint, which helps lessen its impact on the landscape. Importantly, most of the building's program is positioned above a significant geological fault, linking the architecture to the earth's natural features.

Architectural Elements

Two main components define the design: the “cave” and the “pinnacle.” The cave serves as the heart of the building, accommodating spaces such as an exhibition area, café, storage, and a welcome desk. In contrast, the pinnacle stands as a central tower, adding verticality and creating a visual focal point. Together, these architectural elements form a cohesive structure that balances functionality with an appreciation for the landscape.

Spatial Dynamics

The layout encourages visitors to move through various spaces while experiencing the surrounding environment. Strategic arrangements allow for different perspectives, inviting users to engage with both the architecture and the geological setting. This design choice enhances the overall experience, making the connection between people and nature a significant aspect of the visit.

Material Considerations

While specific materials are not extensively detailed, the presentation indicates that the roofing of the amenities is intentionally separate from the central tower. This design decision suggests a deliberate exploration of contrasts between the different elements of the structure. It aims to reinforce the relationship between the cave and pinnacle, enhancing the building's interaction with the site while aligning with the goal of minimizing environmental impact.

The building's height above the fault line allows for impressive views of the Icelandic landscape, offering visitors a chance to reflect on both the architecture and the natural surroundings. This relationship between the built form and the earth encapsulates the essence of the design.

MICROHOME 10: Celebrating Small-Scale Living with €100,000 Prize Fund and Kingspan’s Innovation

`
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.
