Constructed using turf that insulates effectively against Iceland's extreme weather.
02
Integrates an inflatable structure method for efficient onsite assembly.
03
Features a central communal dome surrounded by five distinct private wings.
04
Utilizes a vertical-axis wind turbine for enhanced energy self-sufficiency.
05
Incorporates a waterless, self-contained toilet system for sustainable living.
The Geodesic Turf House is an architectural project situated in Iceland that aims to bridge traditional construction methods with modern sustainability practices. The design reflects the historical essence of Icelandic turf houses while embracing contemporary architectural techniques to create a functional living space. The project explores the interplay between human habitation and natural elements, providing a resilient structure capable of withstanding the region's harsh weather conditions.

The architecture features a geodesic dome at its core, surrounded by five wings that extend outward in a star-like formation. This layout promotes natural light and offers expansive views of the surrounding landscape. The central dome serves as the heart of the house, facilitating communal activities and interaction among residents. Each wing accommodates private living spaces, ensuring a balance between shared and individual areas.

Sustainable Building Materials and Practices

A key aspect of the Geodesic Turf House is its materiality. The primary construction elements include locally sourced turf, steel tubes, flexible insulation, wood, and water-resistant concrete. Turf acts as a natural insulator and integrates the building into the Icelandic landscape while honoring traditional building methods. Steel tubes provide structural integrity, contributing to the house's lightweight framework. The use of flexible insulation is critical in maintaining optimal temperature levels within the building, ensuring comfort for its occupants.

Another distinctive feature of the design is its water management system, which incorporates rainwater harvesting and greywater recycling. This system enhances the structure's self-sufficiency by minimizing external water dependency. The house is also equipped with renewable energy solutions, including vertical-axis wind turbines and solar panels, promoting energy efficiency and reducing the environmental impact of habitation.

Innovative Structural Design and Functionality

The Geodesic Turf House employs innovative construction techniques that enhance its functionality and adaptability. The use of an inflatable structure during assembly addresses logistical challenges often faced in remote locations, simplifying the construction process. The design includes systems for heating and cooking, utilizing turf and wood as energy sources, further aligning with sustainable practices.

Interior spaces are designed with an open-plan concept, particularly in the central dome, allowing for flexible use and communal interactions. The arrangement of private living quarters in the wings ensures residents' privacy while maintaining the possibility of community engagement. Additionally, the incorporation of a waterless, self-contained toilet system exemplifies the project’s commitment to sustainability.

The Geodesic Turf House serves as an innovative model of eco-friendly architecture that respects cultural heritage while addressing modern living requirements in an environmentally sensitive manner. For those interested in a deeper understanding of the project, we encourage exploration of the architectural plans, architectural sections, and architectural designs to fully appreciate the functionality and unique architectural ideas that define this project.

Design a new small-scale home concept in the 10th edition of MICROHOME — 100,000 € prize + construction

Competition organisers

The 10th edition of the MICROHOME architecture competition invites architects and designers from around the world to explore the possibilities of compact, sustainable living. Hosted by Buildner in collaboration with Kingspan and Hapi Homes, this special edition challenges participants to design an off-grid, modular microhome for a young professional couple, with a maximum floor area of 25 m². Designs should prioritize innovation, efficiency, and real-world feasibility. 

A total prize fund of 100,000 € will be awarded, including three main prizes, the Kingspan Award, and the Hapi Homes Award, which will grant 15,000 € and lead to the construction of the selected design. The final registration deadline is September 25, 2025, and winners will be announced on Decebmer 9, 2025. For full competition details and submission guidelines, visit microhome.info.
