Geothermal Timber Structure Bridging Tectonic Plates

Project in-detail

Set against the backdrop of Iceland's tectonic landscape, a timber structure, utilizing yakisugi for durability, elegantly connects two divergent continental plates while providing a sustainable space for visitor engagement and exploration.
5 key facts about this project
01
Two narrow bars symbolize the geological drift of tectonic plates.
02
Integrates a rainwater collection system for sustainability.
03
Uses yakisugi for enhanced durability and weather resistance.
04
Elevated pathing modules guide visitors through the landscape.
05
Provides panoramic views from the low-profile observation deck.

The design is set in the dramatic volcanic landscape of Iceland, specifically focusing on the Grjótagjá cave, which represents the division between two continental plates. It explores ideas of separation and connection through its form and interaction with the natural geological features of the area. Primarily intended for visitors, the structures enhance understanding of the surrounding environment while offering spaces for exploration and reflection.

Conceptual Framework

The layout is defined by two narrow bars that run parallel to the geological rift. One structure is tilted slightly to symbolize the drift of the tectonic plates. This design choice presents a clear visual representation of the ongoing geological changes. The architecture functions as an evolving inter-space, embodying the natural movement of the landscape.

Spatial Arrangement

A thoughtful arrangement improves visitor flow, allowing easy movement across the site. Elevated walkways lead people toward the cave entrances and buildings, fostering engagement with the surrounding geological features. By minimizing disruption to the natural setting, the layout enhances the overall visitor experience and encourages interaction with the landscape.

Sustainability Features

The western structure incorporates the technical components necessary for sustainable operation. The design makes use of geothermal energy systems, providing its own heating and power. In addition, a rainwater collection system and an on-site sewage treatment solution contribute to an eco-friendly approach. These features demonstrate a commitment to sustainability, ensuring that the structures operate in harmony with the environment.

Material Considerations

Materials play a significant role in the overall design. Timber flooring and timber battens constructed from spruce/yakisugi are used, along with black corrugated sheet and softwood cladding. The project also includes thermal glazing with wooden windows, which enhances the connection between indoor spaces and the natural surroundings.

An observation deck integrated into the western structure offers visitors expansive views of the unique landscapes. This design invites people to engage with the scenery and appreciate both the geological features and the architectural expression present at the site.

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.
