Fissured Corten Structure Integrating Geothermal Elements Within Icelandic Landscape

Project in-detail

The observation tower employs a fissured design and corten steel to echo the region's geological features while integrating geothermal technology, serving as a visitor center in the Icelandic landscape.
5 key facts about this project
01
The observation tower is designed to mimic natural fissures in the landscape.
02
Corten steel is employed for its weathering properties, enhancing the building's durability.
03
Geothermal energy is utilized for efficient heating and cooling throughout the facility.
04
Paths lead directly to the Kvennagjà cave, linking nature with the visitor experience.
05
The structure is fully accessible, accommodating visitors of all abilities.

The project is located in the unique landscape of Grjótagjà, which is marked by its significant geological features. The goal is to enhance visitor engagement with this natural environment through a design that harmonizes with the setting. The layout includes various functional spaces, such as access areas, a parking facility, service buildings, and a central observation tower. The overall design concept aligns closely with the tectonic characteristics of the landscape, allowing the architecture to work alongside nature rather than compete with it.

Observation Tower

A key element in the design is the observation tower named Rifa, a term that translates to "fissure" in Icelandic. This tower serves as a focal point for visitors, inviting them to experience the landscape from an elevated perspective. The entryway reflects the natural fissures found in the area, creating an immediate connection to the geological history. The tower allows visitors to observe the surrounding beauty, linking the architectural experience to the landscape itself.

Accessibility Framework

Accessibility is an important consideration in the design. The project features facilities such as changing rooms and relaxation areas strategically placed to serve a broad range of visitors. This thoughtful arrangement ensures that everyone can easily access various parts of the site. By focusing on inclusivity, the design encourages individuals and families to explore and enjoy the natural surroundings comfortably.

Pathways and Connectivity

The pathways within the design are both modular and lightweight. They guide visitors to important areas, including the bathing location at Kvennagjà cave. These paths are designed to blend into the landscape while remaining functional. By maintaining clear routes, visitors can easily navigate the space and appreciate the surrounding natural beauty. The design promotes engagement with the site, allowing exploration without unnecessary barriers.

Material Considerations

The materials chosen for the project include reinforced concrete and corten steel. These materials contribute to the structural integrity of the observation tower while maintaining a connection to the geological context. Glass elements are also used to enhance the experience, allowing for expansive views of the outdoors. In addition, energy-efficient solutions, such as heat pumps and vertical geothermal probes, reflect a commitment to environmental considerations in the design.

The observation tower’s entry, characterized by its fissured form, welcomes visitors into a space that echoes the landscape's natural dynamics. It invites exploration and connection, bridging the gap between architecture and the surrounding environment.

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.
