Cantilevered Lookouts and Carbon-Sequestering Concrete in Icelandic Landscape

Project in-detail

Cantilevered lookouts offer expansive views into a tectonic fissure, while carbon-sequestering concrete integrates sustainability into the design, all serving to enhance visitor engagement with the unique Icelandic landscape.
5 key facts about this project
01
Cantilevered lookouts provide unobstructed views of the fissure formed by tectonic plate separation.
02
Geothermal energy powers the buildings, enhancing sustainability in design and operation.
03
The landscaped grove protects native flora often challenged by volcanic activity.
04
Carbon-sequestering concrete is utilized to reduce the project’s environmental impact.
05
The structures feature walls that disintegrate gradually, allowing for natural light and airflow.

INTERSTICE is an architectural intervention located in the distinctive landscape of Iceland. This area is known for its deep fjords, volcanic deserts, black sand beaches, and snowy mountains. The design aims to enhance visitor access to these natural features while respecting the geological characteristics and cultural significance of the site. The concept emphasizes the connection between the built environment and the surrounding landscape, encouraging exploration and interaction.

Concept and Design Strategy

The design includes two interconnected building halves that guide visitors along separate paths leading to cave entrances and observation points. This arrangement promotes exploration through a network of footpaths that weave throughout the site. The buildings take on organic forms, inspired by the landscape, and as visitors approach, the walls start to open up. This design creates a relationship with the environment by allowing natural light and air to fill the spaces.

Functionality and Visitor Experience

The south structure features an entrance that includes an indoor changeroom and a ticketing area for Kvennagja bathing. The northern building maintains open access to Karlagja at ground level, with a café and staff area positioned above. This layout ensures that essential services are conveniently located near notable natural features. Visitors can easily transition from the structures to cantilevered lookouts that provide expansive views into the fissure, where the American and European tectonic plates meet. This enhances the experience by offering dramatic vistas of the landscape.

Environmental Integration

In the heart of the project is a landscaped grove that acts as a protective area for native plant life. This reflects a commitment to ecological sustainability. By introducing indigenous species, the design acknowledges the challenges presented by volcanic activity and promotes engagement with the landscape. The focus on environmental awareness fosters a deeper understanding of the natural setting’s unique aspects.

Sustainability and Material Use

The project incorporates sustainability principles by utilizing geothermal energy from the surrounding area to meet its operational needs. In support of this commitment, INTERSTICE uses carbon-sequestering concrete and recycled metal for construction. These materials align with modern practices aimed at minimizing the ecological footprint. The design situates itself with sensitivity to the local features, ensuring that the geological character of the site remains intact.

The roof design ripples like the land itself, encouraging rainfall collection, which nourishes the native plants below. This connection reinforces the relationship between architecture and the environment, creating a space that acknowledges and respects the natural world.

`
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.
