Utilizing charred wooden shingles and laminated timber, this initiative redefines sustainable living in the Kherson region through innovative rainwater harvesting systems and adaptive micro homes that promote community resilience.
5 key facts about this project
01
Charred wooden shingles enhance durability and weather resistance.
02
Cross-laminated timber panels provide structural efficiency and sustainability.
03
Innovative rainwater harvesting systems optimize water usage for residents.
04
The bent A-frame design maximizes interior space and natural light.
05
Wastewater separation promotes recycling and reduces environmental impact.

### Concept Overview
Located in the Kherson region of Ukraine, the project addresses acute water scarcity exacerbated by geopolitical instability and damage to infrastructure. The intent is to develop innovative housing solutions that prioritize sustainable living, communal engagement, and resilience to environmental challenges.

### Spatial Configuration
The layout consists of a cluster of micro homes designed around a central water management feature. This configuration enhances natural water flow and encourages interaction among residents. The homes are strategically positioned to optimize water management techniques while fostering a sense of community.

### Materiality and Sustainability
The design primarily employs biobased materials to ensure minimal environmental impact and facilitate disassembly at the end of their life cycles. Key materials include dowell laminated timber for structural integrity, water-resistant finishes, and recycled rubber for sound absorption. A sustainable roofing system is incorporated to eliminate the need for adhesives, thereby enhancing recyclability. Innovative strategies for water management are integrated into the design, including systems for rainwater collection, a dual sewage system to separate grey and black water, and vacuum toilets that significantly reduce water usage.

Each micro home, measuring 25 square meters, prioritizes comfort through efficient space utilization, functional kitchens, and integrated privacy solutions, all while maximizing natural light through large windows. The approach not only reflects an emphasis on user experience but also integrates the living environment with the surrounding landscape, fostering a harmonious connection between indoors and outdoors.

The Buildner’s Unbuilt Award 2025: Celebrating Architectural Creativity and Visionary Unbuilt Designs with a Total Prize Fund of €100,000

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
