Corten Structures Amplifying Volcanic Landscapes in Reykjavik

Project in-detail

Corten structures rise from the volcanic landscape in Reykjavik, thoughtfully designed to enhance visitor interaction with the unique geology of the Grjótagjá Caves while providing essential services and observation points.
5 key facts about this project
01
Corten steel exterior mimics the local volcanic rock.
02
Openings direct views to significant landscape features.
03
Pedestrian pathways minimize ecological disturbance.
04
Geothermal heating utilizes the natural landscape.
05
Design allows for phased visitor exploration and engagement.

The ARAGÓNÍT project is located in Reykjavik, near the Grjótagjá Caves along the Mid-Atlantic Ridge. The design seeks to enhance visitor interaction with the unique geology of the area while reflecting the natural characteristics of the landscape. Inspired by tectonic plate separation, the project draws on local geological elements, especially Aragonite, a rust-colored form of calcite. The architecture integrates with the environment, creating a connection between the built structures and the surrounding natural beauty.

Tower Building

The Tower Building features an envelope that hides its structural components. This design gives it a strong presence that fits well with the volcanic landscape. The eastern side has an expansive opening, allowing for unobstructed views and a sense of openness. Large windows on the southern and northwestern sides direct attention to significant landscape features. Inside, the layout invites visitors to ascend via a grand staircase, leading to various observation points. Each floor provides a unique perspective of the surroundings, enhancing the experience as guests move upward.


Service Building

The Service Building showcases a prism-like design, characterized by a solid northern facade and openings on the other three sides. Large glass windows are placed strategically to maximize natural light, creating a bright and inviting interior environment. This building houses essential services for visitors, including an information point and a café. The layout supports interaction and engagement with the geological features of the area, making it a focal point for visitors.


Pathway System

Surrounding both buildings is a network of pedestrian pathways that connect them while protecting the environment. This modular design minimizes ecological disruption, allowing visitors to explore the area without damaging the landscape. The pathways are elevated on a few support points, reducing soil erosion and preserving vegetation. This thoughtful approach encourages exploration while maintaining the integrity of the site.


Energy Efficiency

The project incorporates a focus on energy efficiency, utilizing geothermal heating systems to leverage the natural heat from the volcanic landscape. This approach helps maintain comfortable indoor environments year-round. Furthermore, the potential addition of solar panels on the roofs can enhance the sustainability of the design, minimizing its environmental impact.


Corten steel forms the exterior of the buildings, with its weathered look complementing the rugged terrain. Concrete foundations provide stability, making ARAGÓNÍT a suitable response to the challenges and opportunities posed by its remarkable setting. The overall design encourages visitors to appreciate the landscape while providing essential services and comfort.

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.
