Constructed on concrete tetrapods with plywood sheathing, this floating community adapts to rising water levels while providing sustainable living solutions for coastal residents.
5 key facts about this project
01
Constructed using stable concrete tetrapods as a foundation to withstand shifting water levels.
02
Plywood sheathing enables lightweight construction while enhancing durability.
03
Designed to encourage communal living with integrated shared spaces for residents.
04
Flexible modular units allow for adaptation to changing environmental conditions.
05
Strategically positioned to maintain views and connection to the water's edge.

The New Coastline presents a practical approach to the challenges posed by climate change and rising sea levels. It focuses on modular floating homes that can adapt to shifting water levels while providing sustainable living options. The design changes the way residents interact with their surroundings, moving from a focus solely on protection against water to a more harmonious integration with the aquatic environment.

Materials

The structure uses specific materials that are key to its functionality and resilience. Concrete tetrapods act as foundational elements, known as 'tidal breakers,' providing necessary stability for the floating units. This foundation is vital for ensuring the homes can endure the forces of flooding and storm surges.

Plywood sheathing forms the outer layers of the modular units, offering durability along with a lightweight quality that is well-suited for floating buildings. To improve energy efficiency, insulation materials are included to maintain comfortable indoor conditions while reducing energy use. Waterproofing methods protect the structures from moisture, and concrete bonded particle board enhances overall strength and durability.

Community Integration

Each modular unit is designed to foster a sense of community, rather than functioning solely as an individual home. The layout encourages social interaction among residents, with communal spaces that promote shared experiences alongside private areas. Flexibility in the design allows for the arrangement of living spaces to accommodate various public and private activities, leading to stronger neighborhood ties.

Design Outcomes

The architectural approach of The New Coastline addresses a range of social and environmental issues faced by coastal communities. By incorporating elements that support community living, the design enhances the sense of belonging among residents. The arrangement creates opportunities for cooperation while preparing the community for the uncertainties brought about by climate change.

The floating homes provide stunning views and maintain a visual connection with the water, enriching the residents' experience of living close to nature. The combination of architecture and environment invites appreciation of both, making every interaction within these homes a reflection of this careful balance.

`
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.
