The Mekong Delta, located in southwestern Vietnam, is characterized by a complex network of rivers and channels that define the area’s landscape and way of life. The project focuses on addressing the challenges posed by the region’s fluctuating water levels through a modular dwelling system. This design incorporates traditional architectural practices of elevating homes above potential flooding, merging them with modern modular approaches to create living spaces that can adapt effectively to the local environment.

Modular Dwelling System

At the heart of the design is a modular structure that allows residents to adjust their homes according to the changing water levels. Using prefabricated light wood frameworks and interchangeable panels, this system enables elevation during floods and allows for a return to ground level when waters recede. Such flexibility is vital in ensuring a functional living environment that can adjust to the dynamic conditions of the Mekong Delta.



Natural Ventilation and Light

The layout of the modular panels is carefully planned to enhance natural ventilation and light inside the homes. Windows and openings in the panels promote airflow and bring natural light into the living spaces. This design consideration helps create comfortable interiors while protecting occupants from harsh weather conditions. The result is an environment that supports well-being and connects residents to their surroundings.



Economic Feasibility

The project aims to serve low-income residents by incorporating affordable design strategies. The choice of inexpensive materials ensures that construction remains financially accessible. This focus on economic viability fits within the social context of the Mekong Delta, where many households experience limited financial resources. By prioritizing cost-effective solutions, the design promotes a sustainable approach that reduces dependence on non-renewable resources.



With its flexible design, the dwelling system establishes an ongoing relationship between the built environment and the natural landscape. Each modular home responds to seasonal water changes, demonstrating a practical solution that respects both traditional practices and modern needs. The project illustrates a commitment to creating living spaces that adjust to their environment while offering a functional and sustainable future for the residents of the Mekong Delta.

`
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.
