For decades overlooked, the Port Area of Rio de Janeiro is now preparing for a historic transformation. An investment of R$ 5 billion aims to create a groundbreaking urban complex in the country, combining regenerative architecture, massive reforestation, and green technology.
The Mata Maravilha project, combined with the Port Park, is not just an urban project; it is a global statement that it is possible to reconcile cities, the environment, culture, and innovation. There will be 223,000 m² of total area, with more than 40,000 native trees and shrubs, floating squares, open-air museums, hotels, coworking spaces, and residences integrated into urban biomes.

A crushed fossil was forgotten for over 40 years inside a museum drawer — when an undergraduate student reconstructed it in 3D, it revealed a carnivorous dinosaur that should not have existed during that period in Earth’s history.
The proposal goes beyond aesthetics. With carbon-zero infrastructure, water self-sufficiency, and smart climate regulation systems, Rio positions itself to become the first “Nature Positive” city on the planet, placing nature at the center of urban development.
Mata Maravilha: The Project That Promises to Redefine the Porto Maravilha by 2027
The Mata Maravilha is one of the most ambitious urban and environmental projects in the history of Rio de Janeiro. Conceived by AI Moinho Real Estate Enterprises, a partnership between businessman Alexandre Allard and the Autonomy Capital fund, the project was selected in a public tender by the City Hall of Rio and aims to transform 223,000 m² of the Port Area into a true regenerative urban ecosystem.
Almost 50% of the area will be composed of native Atlantic Forest vegetation, creating a green belt with over 40,000 trees and shrubs. The proposal aims to restore the biodiversity that once dominated Guanabara Bay to the center of Rio, in addition to creating a space that unites nature, culture, innovation, and economic development.
The development arises where the Moinho Fluminense once stood, a symbol of the 19th-century industrial era that is now decommissioned. This historic building will be restored and become the heart of a complex that unites heritage preservation, green architecture, and regenerative technologies.
More than just reforestation, the project seeks to make Rio the first “Nature Positive” city on the planet, where urban growth generates net benefits for the environment. The estimate is that the complex will have an impact on local temperature reduction of up to 8°C, in addition to operating in a carbon zero model and being self-sufficient in water and energy.
The project is not limited to green areas. It also includes the construction of hotels, cultural spaces, technological hubs, and residences for up to 2,500 residents, in addition to sand trails measuring 7 km in length, interconnecting spaces within the urban forest.
Port Park: A New Green, Floating, and Cultural Waterfront for Rio de Janeiro
Alongside the Mata Maravilha, the City Hall of Rio is planning the Port Park, a new public space that will transform the waterfront of the Port Area. The project envisions an open waterfront for socializing, leisure, and culture, connecting the city to Guanabara Bay.
Inspired by international projects such as Little Island in New York, the Port Park will feature floating squares, community gardens, sports courts, bicycle paths, open-air museums, and a large suspended path for pedestrians and bicycles, all integrated sustainably with no need for landfills.
The plan also includes the construction of a new pier for cruise ships, which will free up the old port warehouses for cultural, gastronomic, and commercial activities. This transformation will continue the revitalization process that began with the Porto Maravilha.
The project will be developed in two phases. The first phase covers the section from Praça Mauá to Warehouse 7, with construction expected to begin by the end of 2024. The second phase aims to incorporate the Islands of Santa Bárbara and Pompeba, which would be transformed into parks and cultural centers, including a museum of monumental sculptures — a kind of “Carioca Inhotim”.
The goal is to create a new relationship between the city and its waterfront, returning to the population a sustainable, accessible, and integrated space, without compromising port operations, which will continue to function properly.
Green Technology and Regenerative Architecture: The Heart of the Project
At the core of Mata Maravilha is the proposal to create an environment that combines bioarchitecture, artificial intelligence, and green technologies. Every element of the project has been designed to generate positive impacts on the environment and urban quality of life.
The main structures are the Vertical Forest Towers of Atlantic Forest, two 70-story buildings completely covered by native vegetation from base to top. Inspired by the Bosco Verticale in Milan, these towers will function as true urban lungs, capable of capturing up to 30 tons of CO₂ per year, in addition to improving humidity and reducing surrounding temperatures.
The complex will feature systems of natural water filtration, rainwater reuse, passive thermal control, and clean energy production. Furthermore, it will be entirely self-sufficient in water and temperature, operating with zero carbon emissions.
Technology will be present in all operational aspects, with sensors and smart climate control systems, biodiversity monitoring, and energy management. This environment will also host a green technology hub (Hub Aya), with coworking spaces, incubators, research centers, and spaces for green tech and AI startups.
The entire project was designed by the renowned Safdie Architects, known for works like the Jewel Changi Airport in Singapore, a global reference in integrating architecture with nature.
Social, Cultural, and Economic Impact: Inclusion, Jobs, and Historical Memory
One of the fundamental pillars of Mata Maravilha is the social commitment. The project recognizes the historical importance of the Port Area as a territory of resistance, especially for black movements, and is committed to actively including local communities in the development process.
There will be social and cultural committees, formed by representatives from communities, cultural leaders, and anti-racist movements, ensuring that the project respects both the historical heritage and the existing social dynamics of the territory.
In addition, there will be direct support for the local creative economy, with spaces dedicated to organic producers, artists, fashion designers, and local designers, integrated into the six biomes of the project, which include gastronomy, fashion, culture, longevity, hospitality, and regenerative business.
The estimate is that the project will generate thousands of direct and indirect jobs, as well as specialized training in the areas of green technology, bioarchitecture, and urban innovation.
The restoration of historical buildings, such as the Moinho Fluminense, also plays a fundamental role in preserving collective memory, preventing gentrification, and promoting inclusive and sustainable urbanization.
The Future of Rio: How Mata Maravilha Can Make the City a Global Reference in Sustainability
The impact of Mata Maravilha and the Port Park transcends the borders of Rio de Janeiro. If implemented as planned, these projects could position Rio as a global reference in regenerative urbanism and sustainable development.
Compared to Cidade Matarazzo in São Paulo, restored by the same creator, Alexandre Allard, Mata Maravilha represents an evolution in scale, ambition, and impact. While Matarazzo revitalized a city block, the Port Maravilha project aims to reforest 223,000 m² and establish a new model of urban space.
Rio is preparing to welcome up to 15,000 digital nomads, engineers, and professionals from the creative economy, as well as attract startups, research centers, and global companies interested in sustainable development and regenerative technology.
If successful, the project could serve as a blueprint for other metropolises seeking real solutions for the environmental and urban challenges of the 21st century, solidifying Rio as a global capital of green innovation, bioarchitecture, and urban regeneration.
