Constructed with Cor-Ten steel and designed for natural ventilation, this small, semi-floating home adapts to its coastal environment while providing a sustainable living space.
5 key facts about this project
01
Water Yard serves as a dynamic buffer zone between communal and private spaces.
02
Cor-Ten steel cladding enhances durability while blending into the marine environment.
03
Natural ventilation is maximized through a large, open intermediate area.
04
Utilizes marine currents for electricity generation via integrated systems.
05
Design includes a dry toilet system to minimize waste and improve sustainability.

Dock House is located in a temperate oceanic climate, famous for its calm waters and four distinct seasons. The design focuses on creating a close relationship between living spaces and the coastal setting. It is a semi-floating structure that highlights sustainability and flexibility. The layout is organized around two connected pavilions, allowing for both communal and private areas.

Architectural Layout

The design features two pavilions that are linked by a space called the "Water Yard." This area serves as a bridge between public and private functions. In the first pavilion, areas for cooking, sharing, and working come together to encourage social interactions. The second pavilion is dedicated to sleeping, storage, and bathing, providing the necessary privacy for its occupants while maintaining a clear functional separation.

Functional Design Strategies

Dock House uses a thoughtful approach to space by organizing horizontal and vertical planes that do not intersect. This strategy creates visual frames that capture views of the surrounding landscape, enhancing the experience of the interior. Careful attention is given to enclosures, which protect residents from external elements and reduce direct sunlight, ensuring comfort in various weather conditions.

Sustainability Features

Sustainability plays a vital role in the design. Dock House includes systems that harness the energy of natural marine currents for electricity. It utilizes both a horizontal propeller and a vertical float system to generate power. Additionally, a dry toilet is part of the design to lower waste production, and a desalination system processes non-potable water, reducing reliance on outside resources.

Materiality and Construction

The construction includes phenolic plywood flooring and Cor-Ten steel panels. These materials provide strength and contribute to the overall aesthetic of the design. Glass wool insulation helps to maintain a stable temperature within the house, despite high levels of humidity outside. This careful selection of materials enhances both functionality and visual appeal throughout the project.



Natural ventilation is achieved through the large Water Yard, which promotes air circulation within the spaces. This design choice supports a constant renewal of air, improving indoor comfort. Overall, Dock House reflects a strong commitment to sustainability and adaptability, presenting a practical and thoughtful solution for living in a coastal environment.

`
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.
