### Project Overview
CoCooN Home is a compact dwelling located in an urban context, spanning 25 square meters, designed to address the contemporary challenges of housing and environmental sustainability. The objective is to create an efficient living space for two occupants, emphasizing minimalism and ecological balance. Through its structure, the design reflects the possibilities of small housing solutions in response to climate change and urbanization.

### Spatial Strategy
The layout of CoCooN Home emphasizes versatility and functionality, featuring distinct zones for various activities. The integrated bath-kitchen area is designed for efficient use of space, combining essential amenities within a compact footprint. The sleeping area prioritizes privacy and comfort, incorporating innovative storage solutions such as a hidden bed closet. Additionally, the eating and working zones are dynamically configured to support both leisure and productivity, accommodating modern remote working needs. Acoustic panels enhance the living environment by mitigating noise pollution, thereby improving overall comfort.

### Materiality and Sustainability
Materials selected for CoCooN Home prioritize both functionality and sustainability. The use of Termowood for wall panels provides thermal efficiency and durability, while wood veneer applied to interiors enhances aesthetic appeal. The project also incorporates sustainable systems, such as a rainwater collection system for irrigation and utility needs, and solar panels that support off-grid energy generation. A vermifilter system addresses wastewater management, promoting environmental responsibility. Multi-functional furnishings, including foldable tables and convertible seating, reflect a commitment to maximizing utility in a compact space without compromising comfort.

`
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.
