The Liveable Pontoon is situated in an ecological area where seawater and freshwater meet, creating the Salt Marshes. This location plays a vital role in shaping the design, which aims to create a strong connection between the living space and nature. The overall concept centers around an open layout that encourages interaction with the environment, providing a simple and functional space for its occupants.

Design Concept

At the core of the design is an innovative approach that removes traditional barriers like walls and windows. Instead of isolating spaces, the structure uses vertical elements to define areas while keeping them connected. This openness allows natural light and airflow to flow freely throughout the living spaces. The layout is organized into overlapping volumes, each serving specific functions. This arrangement enhances the flow and usability of the interiors.

Materiality

Material choices are informed by a commitment to sustainability and environmental awareness. The design employs a combination of curtains and recycled wood panels, which function as a flexible facade. This design choice not only facilitates interaction with the surroundings but also helps maintain privacy. The floor is constructed from terracotta brick made from the local marsh soil. This material connects the structure to its landscape while providing thermal mass to enhance indoor comfort.

Sustainability Features

The project integrates various self-sufficient systems that contribute to its sustainability goals. Energy is generated by utilizing the movement of ocean currents, which powers a system for electricity needed for lighting and water filtration. Rainwater is collected from the roof and directed into a reservoir in the canal. This system ensures that the water stays cool while undergoing treatment for drinking.

The structure floats above the marshland, allowing for both passive and active engagement with the surrounding ecosystem. It creates an environment where occupants can interact with nature while experiencing the tranquil beauty of the Salt Marshes.

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.
