### Overview

The Microhome | Tiny Flying Energy Plant, located in Singapore, is an architectural response to pressing housing and environmental challenges in urban areas. Designed to operate off-grid, this project not only addresses the need for efficient living spaces but also emphasizes sustainability through innovative energy solutions. The integration of modular living concepts allows for adaptability in both urban and rural settings, meeting the demands of contemporary lifestyles while fostering ecological responsibility.

### Spatial Efficiency and Design

The Microhome features a square floor plan that optimizes space utilization while accommodating varying room arrangements. This layout promotes accessibility and facilitates a fluid transition between living and working areas. The elevated structure enhances privacy and mitigates flood risks, while large windows and light tubes ensure ample natural light and ventilation, contributing to a healthier indoor environment. Multi-functional furniture solutions further enhance the flexibility of the internal layout, allowing spaces to transform according to user needs.

### Sustainable Practices

Sustainability is a core principle of this design, which incorporates renewable energy technologies such as photovoltaic panels and wind turbines. A rainwater harvesting system is included to reduce water consumption and promote resource conservation. The use of eco-friendly materials, including insulated façades and sustainable wood frameworks, underlines the project’s commitment to minimizing environmental impact. Collectively, these elements create a minimal-energy footprint, showcasing a holistic approach to sustainable living while serving the needs of a community-oriented space.

`
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.
