Basalt and Cross-Laminated Timber Structure Nestled Within Iceland's Volcanic Landscape

Project in-detail

Constructed with locally sourced basalt and cross-laminated timber, the facility harmonizes with Iceland's volcanic landscape to provide a versatile space for communal interaction and reflection.
5 key facts about this project
01
Constructed with locally sourced basalt, the exterior enhances thermal mass and durability.
02
Cross-laminated timber panels provide structural support while promoting sustainability.
03
A turf-covered roof seamlessly integrates the building with the surrounding landscape.
04
Designed to maximize views of the Northern Lights, the layout encourages outdoor engagement.
05
The facility incorporates geothermal energy for efficient heating and climate control.

## Overview
Located near the Krafla Caldera in Iceland, FISSURE is an architectural response to the region's distinctive geographical and cultural characteristics. This project integrates natural elements with traditional Nordic building techniques, addressing community needs while offering spaces for individual reflection. The design promotes a dialogue regarding the interplay between humanity and the environment, particularly in the context of nature's fragility and resilience.

## Material Selection and Performance
The project's material choices are central to its identity, emphasizing sustainability and respect for local traditions. Key materials include locally quarried volcanic basalt for the exterior walls, which enhances the building's integration into the rugged landscape, and cross-laminated timber (CLT) that provides both structural performance and warmth. Mass timber (GLT) is employed for broader structural components, while concrete serves multiple functional purposes throughout the facility. Unique to the design, the use of turf on the roof not only aids insulation but also further connects the structure to its environment. High-performance triple glazing enhances energy efficiency and offers occupants uninterrupted views of the surroundings.

## Spatial Organization
The exterior design reflects the dramatic Icelandic landscape, featuring a stark black basalt façade contrasted by a green insulated roof. This visual composition draws attention to the building's contextual setting and creates inviting outdoor spaces that respond to diverse climatic conditions. Upon entry, visitors are met by a grand staircase that symbolically bridges the geological past and contemporary experience. Inside, the space is segmented to facilitate interaction and privacy, comprised of airlock areas, multi-purpose relaxation zones, and observation lounges that promote engagement with the natural surroundings. Expansive windows optimize natural light, enhancing both the aesthetic quality of the interior and its energy efficiency, ultimately aligning with the project's environmental goals.

Unique characteristics of FISSURE further enhance its role as a communal space, incorporating elements that foster well-being, connection, and social interaction while honoring Icelandic architectural heritage and prioritizing low-impact construction methods.

`
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.
