Modular Concrete Cabin With Integrated Rainwater Systems and Sustainable Steel Framework

Project in-detail

Modular units crafted from concrete and steel seamlessly integrate rainwater systems while providing flexible living spaces that cater to mountaineers in the remote Icelandic highlands.
5 key facts about this project
01
Modular design allows for flexible configurations based on occupancy.
02
Constructed using lightweight materials for helicopter transport to remote sites.
03
Rainwater harvesting and photovoltaic panels enhance sustainability.
04
Charred wooden shingles provide durability and aesthetic appeal.
05
Interior spaces prioritize natural light and thermal insulation efficiency.

### Overview
The Constructed Cabin project is located in the Icelandic highlands, intentionally designed to respond to the demands of modern mountaineering while drawing from traditional cabin forms. By integrating sustainable design principles with innovative construction techniques, the project seeks to provide accessible and adaptable shelter in remote, challenging mountainous regions. The design aligns with the distinctive qualities of Iceland's landscape, promoting a functional yet aesthetically coherent presence within the environment.

### Spatial Organization and Functionality
The spatial strategy employs a modular approach, breaking the traditional cabin form into smaller, independent units that maximize functionality and flexibility. Each module is designated for specific uses, encompassing both living and resting areas. This layout facilitates various configurations, allowing the modules to function autonomously or collaboratively depending on the number of occupants. Strategically placed openings afford expansive views of the surrounding landscape, enhancing the experience of dwelling within the natural setting.

### Materiality and Sustainable Practices
The material selection emphasizes resilience and environmental compatibility. The exterior utilizes concrete for durability against harsh weather, while a steel framework ensures structural integrity without excessive weight. The warm internal spaces feature wooden panels that foster a comforting atmosphere. In line with sustainable practices, the cabins incorporate photovoltaic panels for energy production, rainwater harvesting systems for effective water management, and portable septic systems that minimize ecological footprints. Furthermore, the transportation process employs lightweight materials and aerial delivery methods to limit environmental impact, enabling installation in otherwise inaccessible areas.

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.
