The revitalization of the Navigli Canal in Milan aims to reconnect this historically important waterway with the modern city environment. Located in the heart of Milan, the canal has long played a key role in the city's development. Its design focuses on combining cultural significance, mobility improvements, and sustainable practices. This initiative seeks to create a lively public space that honors the past while accommodating contemporary urban needs.

Historical Context

The Navigli Canal has been a vital part of Milan's history, serving first as a military defense mechanism and later as a significant navigation route during the medieval period. Over the years, it faced various challenges, leading to its decline and eventual burial in the 20th century. Recently, the Lombardy Regional Council approved a plan to reopen the canal, representing a crucial step in restoring an essential aspect of Milan's identity.

Cultural Strategy

The design places importance on preserving the historical character of the canal while making public spaces more accessible and engaging. The goal is to turn the canal into a community focal point where cultural events and social interactions can flourish. Incorporating historical features will create opportunities for diverse experiences within the urban environment, welcoming both residents and visitors.

Mobility Integration

Improving transportation options is a central part of the plan. The design aims to link the canal with nearby neighborhoods through a network that includes subway lines, bicycle paths, and tram routes. This interconnected transport system will make it easier for people to reach the canal and enjoy its surroundings. Emphasizing alternatives to car travel, the project encourages walking, cycling, and public transport, enhancing the area’s accessibility.

Sustainability Initiatives

Sustainability is a key focus in the project. There is a commitment to enhance green infrastructure along the canal, with plans for lush landscapes that promote biodiversity and improve the local environment. By incorporating plants and green spaces, the design works toward creating a healthier ecosystem. This approach aligns with broader urban goals aimed at encouraging low-carbon commuting options, seamlessly integrating nature into daily life.

The design also highlights a careful reorganization of traffic flow to ensure safety for pedestrians and cyclists. This effort will help bring the canal back into everyday life, allowing the public to engage more with the waterway. As the revitalization unfolds, the canal will showcase a blend of ecological and urban elements along its banks, ultimately enhancing the quality of life in the area.

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.
