The Guarda-Chuva Central is a mixed-use commercial tower located in São Paulo, Brazil. Situated between Praça Armênia and Avenue Tradentes, it addresses key urban issues such as navigation and community interaction. The design aims to create a space that connects various socio-economic groups while incorporating sustainable practices through vertical farming.

Design and Structure

The building has a tapering form that enhances natural light while offering occupants panoramic views of the city. Each level includes diverse programmatic elements, such as food and beverage outlets, retail spaces, and offices. This arrangement encourages movement and interaction among users throughout the interior. Additional amenities on the upper levels contribute to the overall functionality of the tower.

Sustainability Features

Vertical farming is a significant aspect of the Guarda-Chuva Central. The design employs aquaponics to establish a self-sustaining system, allowing for local food production. This method minimizes dependence on external resources and promotes education on sustainable agriculture. Integrating farming into the urban environment not only serves the community but also highlights a commitment to environmental responsibility.

Transportation Connectivity

Located near public transportation options, including bus stations and an underground train station, the building makes it easy for people to access the site. This careful planning aims to reduce traffic congestion and air pollution, contributing to a healthier urban setting. The design considers the existing conditions and cultural significance of the neighborhood, creating a structure that feels connected to its surroundings.

Water Management

Water management strategies involve using the nearby canal as a source for the vertical farming initiatives. By filtering polluted water, the building supports sustainable agricultural practices. Local artisans are also involved in the project, adding craftsmanship and a sense of community to the design.

The interplay of integrated green spaces throughout the structure draws attention and emphasizes the connection between nature and the urban environment.

`
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.
