The Micro House project addresses the increasing need for affordable housing, focusing on compact living solutions that enhance the quality of life. Set in an urban environment, the design prioritizes efficiency and accessibility for low-income groups. The overall approach combines thoughtful architecture with practicality, showing how well-planned spaces can meet essential living needs.

Spatial Efficiency

The Micro House has a footprint of 24.40 square meters, organized to make the most of every inch. It includes a living area of 7.13 square meters, a kitchen measuring 4.87 square meters, an 8.20 square meter bedroom, and a bathroom with integrated laundry of 4.20 square meters. This open-plan layout supports flexible living, allowing residents to adapt the space to their day-to-day activities. It balances comfort and functionality.

Light and Ventilation

Natural light and fresh air are important features of this design. Jalousie glass windows and sliding doors are strategically placed to encourage airflow and brighten the interior. These elements work together to create a pleasant atmosphere, reducing any feelings of confinement that small homes might have. The design also includes a porch that extends the living area, with a wall planting system that connects the indoors with nature.

Material Selection

The walls of the Micro House use EPS sandwich panel systems, known for their durability and low upkeep. This choice supports sustainability and practicality in construction. Inside, the walls are painted white, which makes the space feel open and airy, contributing to a sense of freedom within the constraint of a smaller footprint.

Utility Integration

Solar panels are installed to provide renewable energy, decreasing the need for traditional energy sources. Additionally, the home has a built-in septic tank for waste management and a rainwater collection system that supplies water for various household needs and irrigation for plants. Together, these features demonstrate a commitment to efficiency and environmental responsibility.

The design effectively blends an open loft concept with defined living spaces, allowing residents to navigate seamlessly through their home. Each element works together to create a functional and inviting environment, catering to the needs of modern urban living.

`
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.
