COR-TEN Steel and Hemp Insulation in Modular Retreats for Sustainable Living

Project in-detail

Constructed with COR-TEN steel and insulated with hemp panels, this modular living space elevates sustainable design by seamlessly integrating into its forested landscape while providing essential retreats for residents.
5 key facts about this project
01
Constructed with weathering COR-TEN steel for enhanced durability and minimal maintenance.
02
Hemp insulation panels provide superior thermal performance while promoting sustainability.
03
Elevated modular design facilitates water drainage and reduces soil erosion impact.
04
Strategically placed windows optimize natural light and frame views of the surrounding forest.
05
Integrated gray water treatment system supports efficient water recycling on-site.
This architectural project exemplifies a contemporary approach to sustainable living, demonstrating how design can harmonize with nature. The structure is situated in a rocky terrain, surrounded by a forest, which informs its design elements and material choices. The project encapsulates modular living, featuring interconnected sleeping pods that provide privacy while facilitating natural light and ventilation. The minimalist aesthetic supports a balance between functionality and environmental responsibility.

Sustainability in Design

A key aspect of this project is its unwavering commitment to sustainability. The choice of materials plays a significant role in achieving this goal. The project employs COR-TEN steel for its structural elements, providing durability and weather resistance. Oriented Strand Board (OSB) is utilized for walls, offering cost-effectiveness and sustainability. Hemp insulation panels, available in varying thicknesses, enhance thermal and acoustic performance while reducing the building’s carbon footprint. Additionally, untreated wood beams contribute to both structural integrity and aesthetic warmth.

The inclusion of photovoltaic panels for solar energy capture and a gray water treatment system underscores the project's focus on self-sufficiency. Water drainage solutions are implemented thoughtfully through elevated construction, protecting the surrounding landscape from erosion. These features collectively reflect a design philosophy that prioritizes ecological integrity.

Functional Elements and Spatial Organization

The architectural design prioritizes functionality through a modular layout. Each sleeping pod serves as a distinct space, promoting individual privacy while allowing for communal interaction in shared areas. The organization of spaces is straightforward, facilitating ease of movement and adaptability. Windows are strategically placed to optimize natural light while framing views of the natural surroundings. This approach enhances the user experience, allowing residents to connect with nature seamlessly.

Incorporating innovative building systems, the design enables efficient resource management. The gray water system exemplifies responsible water usage, recycling wastewater for non-potable applications. These design strategies reinforce a commitment to sustainability and resource conservation.

For a deeper understanding of the project’s architectural framework, including architectural plans, sections, and designs, readers are encouraged to explore the full project presentation. This analysis highlights the thoughtful integration of sustainable practices within a functional architectural design, presenting a clear picture of its operational and ecological significance.

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.
