Built from trapezoidal microhomes designed for relocation, the off-grid dwellings incorporate energy-generating turbines and water collection systems, offering a sustainable living solution for residents facing climate change challenges.
5 key facts about this project
01
Microhomes are constructed from two trapezoidal prisms to optimize space and adaptability.
02
Each unit features an adjustable blind system for enhanced privacy control.
03
Off-grid energy turbines are integrated within the hull to generate renewable power.
04
Water collection tanks are built into the design, ensuring self-sufficiency for residents.
05
Recharge stations are strategically located along migration routes to support mobility.

"Typhoon 2087" focuses on creating sustainable housing solutions in Ho Chi Minh City, Vietnam, where climate change poses significant risks. As sea levels rise and natural disasters become more frequent, the design addresses the urgent need for flexible living spaces. The concept centers on relocatable off-grid boat housing, enabling residents to adapt to environmental changes while maintaining a connection to their community.

Microhome Design

The design features a microhome made of two trapezoidal prisms. These prisms are arranged to provide distinct functional areas. One module contains essential spaces such as the kitchen and bathroom, making them readily accessible. The other module offers a flexible living space that can be reconfigured as needed. An adjustable blind system gives residents control over privacy, creating a comfortable environment that can adapt to various situations.

Sustainability Features

Sustainable living is a key aspect of the design. The microhome incorporates off-grid systems that include water collection tanks and energy-collecting turbines integrated into the boat's hull. This setup allows the dwelling to operate independently from conventional utilities. Such features not only promote self-sufficiency but also minimize the environmental footprint of the housing solution.

Mobility and Infrastructure

The design considers the importance of mobility. Recharge stations are positioned along migration routes in major cities and towns. This infrastructure supports moving residents by providing vital resources, making the living solution practical and accessible. The thoughtful placement of these stations reflects an understanding of community needs in areas affected by climate change.

The project also emphasizes the role of the Mekong River as a migration route. This geographical consideration enhances the practicality of the boat housing and ties the design to broader issues of mobility and adaptation to urban challenges. Residents can navigate their surroundings more easily, allowing for a connection to their environment and community, emphasizing resilience in design.

`
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.
