Cross-Laminated Timber Cabin With Green Roof and Rainwater Harvesting System

Project in-detail

Constructed from cross-laminated timber and topped with a verdant green roof, this compact cabin incorporates a rainwater harvesting system to create a self-sufficient living space designed for quarantine use.
5 key facts about this project
01
The cabin features a green roof that enhances insulation and supports local biodiversity.
02
Rainwater harvesting systems are integrated to promote water conservation and self-sufficiency.
03
Cross-laminated timber panels were chosen for their structural integrity and reduced environmental impact.
04
Charred wooden shingles provide natural weather resistance while contributing to the cabin's aesthetic.
05
A multifunctional interior layout maximizes space utility in the compact 12-square meter design.
The Voxel is an architectural project characterized by its compact, self-sufficient structure designed for quarantine living. This 12-square meter cabin exemplifies a contemporary approach to architecture, focusing on sustainability and environmental integration while providing a functional living space. It operates as an autonomous unit, capable of supporting a single occupant in a variety of contexts, making it relevant in today's world, where the need for adaptable living solutions is increasingly recognized.

The design emphasizes the use of cross-laminated timber (CLT), which is not only robust but also offers excellent thermal insulation. This choice of material reflects a commitment to sustainability, as CLT is derived from responsibly harvested wood, contributing to a lower carbon footprint compared to traditional building materials. The incorporation of Aleppo Pine further enhances this ecological focus, showcasing an effort to utilize local resources and minimize environmental impact. The cabin is elevated on supports, which reduces its footprint on the earth and allows for natural drainage, preventing disruption to the surrounding ecosystem.

Integral to the project's function is its innovative use of space. The interior layout is meticulously planned to maximize utility while maintaining a comfortable atmosphere. Multifunctional areas accommodate essential activities such as sleeping, working, and cooking. Large windows are strategically placed to flood the interior with natural light, creating an inviting space that connects the occupant with the outside environment. This thoughtful incorporation of lighting not only enhances comfort but also reinforces the project's sustainability by reducing reliance on artificial lighting.

One of the standout features of The Voxel is its approach to resource management. The design incorporates systems for rainwater collection and filtration, significantly improving water conservation. The cabin collects rainwater and stores it for various uses, demonstrating a practical commitment to self-sufficiency. Additionally, the green roof serves both as an insulating layer and a natural habitat, promoting biodiversity while assisting in managing stormwater runoff. This dual purpose reflects a unique design strategy that aligns with ecological principles.

The energy system of the cabin, featuring solar panels, illustrates a progressive approach in architectural design. By generating renewable energy on-site, The Voxel minimizes its dependence on non-renewable resources. This integration of passive and active design strategies further enhances the building’s efficiency, ensuring that it remains functional throughout various weather conditions.

In terms of aesthetics, The Voxel maintains a modern yet understated design. The façade, composed of repurposed timber slats, presents a visual texture that respects the surrounding landscape while providing privacy for its occupants. This choice of materials not only reinforces the structural integrity but also contributes to a sustainable design narrative by utilizing recycled elements wherever possible. The combination of natural materials and thoughtful design fosters a sense of belonging and comfort, essential for a space intended for prolonged stay.

The Voxel stands out as a prototype for future architectural endeavors focused on environmental sustainability and adaptability. It not only meets immediate needs for quarantine living but also inspires conversations around innovative living solutions that are mindful of ecological footprints. This project transcends mere functionality, positioning itself as a model for contemporary architecture that balances human and environmental considerations. Readers interested in exploring this project in greater detail are encouraged to examine its architectural plans, sections, designs, and ideas to gain deeper insights into the comprehensive approach that defines The Voxel.

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.
