## Architectural Design Overview: Microhome on the Italian West Coast

The microhome is situated along the Italian West Coast, strategically positioned to leverage the Mediterranean climate. The design intent is to merge traditional Mediterranean aesthetics with contemporary building practices, establishing a connection between the structure and its natural surroundings. The project emphasizes sustainable architecture, focusing on climatic responsiveness and user comfort within a minimalist framework.

### Spatial Configuration and Environmental Adaptation

The design draws inspiration from traditional Mediterranean morphology, characterized by compact forms and a strong internal-external relationship that enhances interaction with the landscape. The layout is organized around a central outdoor patio, optimizing both private and communal spaces. By responding effectively to local climatic influences—such as the proximity to the Mediterranean Sea and the surrounding mountains—the building adopts features that facilitate natural ventilation and thermal comfort. This includes a ventilation chimney designed to harness prevailing breezes and ensure effective air circulation.

### Material Selection and Sustainability Initiatives

Materiality plays a critical role in the project's sustainability objectives. The construction employs high-performance materials such as Kingspan Dri design flat panels for insulation and Kingspan Quad Core for enhanced thermal efficiency. Load-bearing walls are built using Poroton-type bricks, while OSB panels provide structural support. The design also integrates ceramic and gravel finishes for durability and water management. A rainwater collection system and photovoltaic modules are incorporated to support self-sufficiency in water and energy. Overall, the material choices reflect a commitment to environmental compatibility while maintaining a connection to traditional aesthetics.

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.
