With 219 Meters and 39 Floors, the Alto das Nações Tower Will Be the Tallest Building in São Paulo in 2025, Surpassing Platina 220 and Offering a 360º Observation Deck, Panoramic Rooftop, and Structure for 10,000 People

The skyline of São Paulo will change radically in the coming years. Under construction in the multi-use complex Paseo Alto das Nações, in the South Zone of the city, a corporate building promises to become the new symbol of São Paulo’s verticalization by reaching an impressive height of 219 meters and 39 floors.

When inaugurated, expected by the end of 2025, the Alto das Nações tower will surpass all other skyscrapers in the capital and take the title of the tallest building in the metropolis.

A New Era for the São Paulo Skyline

The tower under construction will be located on Avenida Nações Unidas and will be part of a large development by WTorre.

Its height will exceed the 172 meters of Platina 220, inaugurated in 2022 in Tatuapé and currently holding the title of the tallest in the city.

In addition to the corporate building, the complex will house a shopping center with over 40 stores, including a Carrefour hypermarket, a mixed-use tower, a residential tower, and a park spanning 32,000 square meters.

According to Carrefour Property, one of the companies involved in the construction, the first phase of the project was completed in December 2022 with the delivery of the Paseo Alto das Nações shopping center.

The second phase, completed in 2023, included the mixed-use tower with seven corporate floors and 18 residential ones — totaling 161 units at 113 meters tall — as well as a public square and the integration of the complex with the Granja Julieta station of Line 9-Esmeralda of CPTM.

Construction at an Accelerated Pace and Daily Challenges

The corporate tower, which will be the tallest building in São Paulo, is still under construction and is expected to be completed by the end of 2025.

The residential tower, with 38 floors, 216 units, and a height of 133.96 meters, is set to be inaugurated by the end of 2026, completing the entire project.

Walter Genovez, engineering director, highlighted to Estadão the magnitude of the work and the challenges faced daily. “Every day, we are the tallest tower in São Paulo. We started this project, the most iconic in the city, in February 2021, and we are continuing to progress with this large-scale construction. We are finalizing the concrete superstructure, installing glass facades and elevators simultaneously,” he stated.

Genovez also emphasized the importance of safety on the construction site. “The height is a challenge we face every day: wind, rain, logistics. We have to balance safety, quality, and deadlines. If we need to stop, we stop. Safety comes first,” he said.

The construction schedule anticipates an aggressive pace, executing two and a half slabs per month, each with over 2,500 m².

From the First Carrefour to the Urban Project of the Future

The Alto das Nações project carries a special symbolism: it is being built on the same land where the first Carrefour store in Brazil operated.

According to Guilherme Nargara, project director, this historical connection adds to the proposal of transforming the area into a new urban hub. “Here we are exactly at the site of store number one. We built a new store, the mixed-use tower, and the square that connects with Rua Alexandre Dumas. Now we have reached the third phase: the corporate tower, which will be the largest office tower in Brazil and São Paulo,” he explained.

The building is expected to accommodate around 10,000 people and will feature 33 elevators divided into four zones, as well as escalators.

The project includes a private square for public use with 32,000 m², a theater, and various commerce and service options, aiming to keep foot traffic active throughout the day and prevent the area from becoming deserted at night.

Panoramic Observation Deck and Experiences at the Top

One of the differentiators of the Alto das Nações tower will be its rooftop, which will function as an observation deck open to the public. The space will offer a 360º panoramic view of São Paulo, including Avenida Paulista, Marginal Pinheiros, and even Guarapiranga Reservoir.

Additionally, there will be a special attraction: a glass box projected out from the building, allowing visitors to feel as if they are “floating” over the city, similar to experiences offered in iconic buildings in Chicago.

The Race of São Paulo Skyscrapers

The construction of the Alto das Nações tower represents a new chapter in the story of verticalization in São Paulo. In 2022, Platina 220 took the lead by reaching 172 meters, surpassing Mirante do Vale (170 m) and Figueira Altos do Tatuapé (168 m).

The arrival of new giants reflects the trend of replacing houses and small buildings with large towers, especially in traditionally horizontal neighborhoods.

However, this process does not occur without controversies. Urban planner Lucas Chiconi, a resident of Tatuapé, stated to g1 that intense verticalization can erase the memory and identity of neighborhoods.

In 2019, he was part of a group that tried to prevent the demolition of houses from the 1950s belonging to the João Migliari worker village, just one kilometer from Platina 220.

Twenty of the 60 houses were demolished for the construction of a new project, and the remaining ones were destroyed even before being assessed by historical heritage agencies.

Height Has Always Been a Matter of Debate

The quest for height is not a recent phenomenon in São Paulo. Since the 1920s, the city has discussed the limits of verticalization. In 1924, the Sampaio Moreira building, with only 12 stories, caused astonishment by breaking the six-story standard of the time and was called “ugly” by many São Paulo residents.

The title of tallest building was short-lived. In 1929, the Martinelli building was inaugurated next to the Sampaio Moreira, starting a competition for height that would last for decades and cross borders, with rivalries even with Argentine constructions.

A New Icon for the Largest City in the Country

With the completion of the Alto das Nações tower, São Paulo will gain not only a new architectural landmark but also a symbol of its ongoing urban transformation.

The building will not just be the tallest in the city: it will represent the combination of modernity, functionality, and innovation, with communal spaces, an observation deck open to the public, and integration with public transport and commerce.

More than altering the São Paulo skyline, the tower will be part of a broader proposal for urban reconfiguration, where work, leisure, services, and mobility coexist in the same space. In 2025, when the structure is finally inaugurated, the city will witness not just a record-breaking building, but a new chapter in its vertical history.
