### Concept Overview
Located in a coastal environment, The LightHouse addresses the pressing issues of rising sea levels and urban density through the design of a microhome that promotes sustainability and functionality. The structure aims to provide residents with a lifestyle that is both practical and reflective of its aquatic surroundings. It is conceived as an adaptable living space that fosters a connection between the occupants and the natural landscape.

### Spatial Organization
The LightHouse features a two-level layout designed to facilitate indoor and outdoor interactions effectively. The ground floor encompasses approximately 16.43 square meters and includes communal areas such as a kitchen, living space, and storage solutions. The design emphasizes versatility, allowing for social gatherings and functional use of space. The upper level comprises a private bedroom, measuring 8.29 square meters, which benefits from extensive glazing, offering expansive views of the surrounding water and landscape.

Key elements of the spatial layout include:
- **Kitchen and Living Area**: The kitchen is strategically designed to encourage communal cooking experiences, while the living area offers flexible seating arrangements conducive to gatherings.
- **Private Bedroom**: This upper-level space prioritizes comfort and tranquility, with operable deck features that enhance the user experience and enable unobstructed engagement with the views.

### Materiality and Environmental Considerations
The construction of The LightHouse employs materials selected for their sustainability and resilience in marine contexts. Notable materials include:
- **Molded Shells (Prefabricated Off-Site)**: This structural key component supports efficient transport and installation while ensuring stability in coastal conditions.
- **Recycled Boat Fiber Reinforced Plastic**: Utilized for durability, it incorporates recycled elements to minimize environmental impact.
- **Solar Panels (25 kW)**: Installed for energy production, these panels support a hydrogen electrolyzer that contributes to sustainable energy use.
- **Detachable Floating Modules**: Designed to accommodate variable user needs, these modules enhance the adaptability of the home.
- **Water Harvesting Systems**: Integrated technology for rainwater collection ensures responsible water management practices.

Through these materials, The LightHouse serves as a model for resource conservation and energy efficiency, fostering an environmentally conscious approach to 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.
