5 key facts about this project
01
Utilizes 3D printing technology for efficient construction.
02
Incorporates fiberglass insulation for enhanced energy efficiency.
03
Features a rainwater collection system for sustainable water use.
04
Modular design allows for flexible living configurations.
05
Designed specifically to adapt to rising sea levels in coastal areas.

The design features a modular houseboat concept located in a coastal area facing the challenges of rising sea levels. This approach provides a practical solution to urban living in environments that are vulnerable to water fluctuations. The houseboat integrates sustainability and energy efficiency into its core, offering both passive and active systems for maintaining comfortable living conditions. Community spaces are central to the design, encouraging interactions among residents.

Sustainability Focus

Sustainability is a primary focus, with the design addressing key issues such as energy use, water efficiency, and construction waste. The modular nature of the houseboat allows for varying layouts that adapt to different family sizes and lifestyles. Each component is thoughtful, providing flexibility and practicality. This approach meets the needs of modern living while being mindful of environmental impacts.

Innovative Resource Management

The houseboat incorporates an efficient water management system, prominently featuring rainwater collection for use in bathrooms and kitchens. This reduces the demand for municipal water, demonstrating a commitment to sustainable resource practices. Active heating and cooling systems benefit from solar panels, which help reduce energy consumption. This combination ensures a comfortable environment while promoting eco-friendly living.

Material Utilization

Materials are selected to enhance both design and function. The houseboat uses 3D printed concrete, which allows for accurate construction while minimizing waste. In addition, fiberglass insulation improves thermal performance, working alongside the houseboat's active systems for climate control. Sea-foam is also used, enhancing insulation and energy efficiency to make the space comfortable for all occupants.

Community Engagement

The design includes shared internal and external spaces that encourage social interaction among residents. These communal areas are carefully arranged to promote engagement, reflecting a desire for connection in residential living. The focus on community is significant, as it aligns with a growing recognition of the importance of relationships and shared experiences among neighbors.

Attention to small details benefits the overall functionality of the houseboat. For instance, the solar hatch allows for natural light while also providing ventilation, ensuring that living conditions remain pleasant and connected to the outdoors. This detail highlights the thoughtful design intended to enhance everyday life in a unique living 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.
