Charred Wooden Shingles and Cross-Laminated Timber Create Modular Retreats in Icelandic Landscapes

Project in-detail

Modular cabins constructed from charred wooden shingles and cross-laminated timber offer a sustainable retreat, seamlessly integrating into the rugged Icelandic landscape while providing essential amenities for outdoor enthusiasts.
5 key facts about this project
01
Modular units enable flexible configurations for diverse user needs.
02
Charred wooden shingles enhance durability while blending with the landscape.
03
Steel columns elevate the cabins, minimizing land impact and frost heave risk.
04
Rainwater harvesting system ensures sustainable water supply for occupants.
05
High-efficiency glass maximizes natural light and outdoor connections.
The TREXAGON project focuses on the design and development of modular trekking cabins tailored for outdoor enthusiasts. Designed with an emphasis on simplicity and adaptability, these cabins offer a sustainable solution for users seeking immersive experiences in nature. The innovative architecture is particularly suited to challenging landscapes, making it relevant for regions such as Iceland, known for its unique geological features and environmental conditions.

The cabins utilize a modular system composed of hexagonal units, allowing for easy assembly and customization based on user needs and site conditions. Each unit connects effortlessly, facilitating a range of configurations from individual cabins to larger collective spaces. This design approach prioritizes both functionality and aesthetic integration with the surrounding environment.

Modularity and Configurability
A defining characteristic of the TREXAGON cabins is their modular design. Comprised of identical hexagonal modules, these structures can adapt based on group size and intended use, providing options from compact one-unit arrangements to more extensive multi-unit complexes. Each unit's flexibility allows for efficient transport and assembly, significantly reducing construction time and labor costs. Diverse layouts enable various living arrangements, including communal areas, private sleeping quarters, and functional spaces for cooking and relaxation.

Sustainable Design Elements
The architectural design of TREXAGON incorporates several sustainable features that address environmental challenges. The cabins are elevated on steel columns to minimize land disruption and manage drainage effectively in areas prone to frost heave. The exterior cladding consists of blackened wood, a traditional material that provides durability while blending seamlessly into Iceland's dramatic landscapes. The design also integrates renewable energy sources, such as solar panels, for powering the cabins and a rainwater harvesting system that ensures a reliable water supply. Additionally, a wood-burning stove offers efficient heating, allowing users to maintain comfort in varying weather conditions.

The thoughtful combination of these sustainable elements not only fulfills practical requirements but also enhances the cabins' overall environmental footprint. Each unit is designed to facilitate easy maintenance while promoting long-term use, making TREXAGON a responsible choice for outdoor accommodation.

For those interested in delving deeper into the architectural plans, sections, and innovative designs of the TREXAGON project, explore the full presentation to gain comprehensive insights into its unique architectural ideas and practical applications in trekking cabin design.

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.
