Off-Grid City Parasite is a project located in Chengdu that addresses the city's escalating housing crisis caused by rapid urban development. As neighborhoods face demolition to clear space for infrastructure, a solution emerges to support those temporarily displaced. The design aims to reclaim gray spaces, particularly beneath the city’s viaducts, transforming them into functional community living areas.

Design Components

The individual housing pods feature two main parts: a solid core and an inflatable shell. The solid core is essential for providing privacy and a strong structure, creating a stable living environment. This focus on privacy is vital as urban areas grow denser and personal space becomes increasingly limited.

On the outside, the inflatable shell serves several adaptive functions. It acts as a buffer against noise and vibrations from the busy urban environment, enhancing the comfort of residents. This design allows the housing pods to connect with their surroundings while maintaining a sense of tranquility for those living inside.

Adaptive Urban Integration

The concept of the housing pod reflects a "parasite" quality, allowing it to attach to underused spaces previously considered uninhabitable. This strategy revitalizes neglected areas and shows how thoughtful design can meet the challenges of modern urban living. By reimagining infrastructure as usable living space, the design encourages a shift in perspectives about how cities function.

Sustainability and Efficiency

Although specific materials are not highlighted, the nature of the inflatable shell indicates a preference for lightweight and flexible options that support easy setup and adaptability. This aligns with the overarching goal of sustainability, maximizing both space and resources effectively. Off-Grid City Parasite illustrates a modern response to housing needs by integrating innovative design with environmental considerations.

The design also creates a balance between individual and communal living. Micro homes provide personal sanctuaries while fostering connections among residents. Each pod embodies the idea of adaptable urban living, forming a cohesive environment where people can thrive amid the complexities of city life.

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.
