Senna Tower

History

The Senna Tower is FGi‘s (FG Empreendimentos) tallest bet, the developer that already holds much of Balneário Camboriúi‘s record-breaking towers, and it is born under licence from the Sennai brand — the legacy of racing driver Ayrton Senna turned into a building’s signature. The project was announced as the development that will make the Santa Catarina city home to the tallest exclusively residential building in the world, surpassing benchmarks such as New York’s Central Park Tower in the strictly residential segment.

Construction began in 2025, on Avenida Atlântica, in the Barra Sul vector — the same stretch where FGi and Pasqualotto & GTi have concentrated the new generation of signature towers. It is the latest chapter in a lineage of records the city has accumulated: Millennium Palacei was Brazil’s tallest building from 2014 to 2019, Yachthouse by Pininfarinai took it over in 2023 at 294 metres, and the Senna Tower is born to double that mark.

• Concept: a residential super-skyscraper with sporting-brand pedigree, with few, very large-format units per floor, suspended mansions and penthouses at the top of the greatest residential height on the planet.
• Trivia: the development is often marketed as “the tallest building in the world” within the residential category; the Sennai brand lends the project the same world of performance it licenses to high-end products in Brazil and abroad.

Architecture and aesthetics

The tower is conceived as an isolated vertical landmark on the waterfront, with a glass façade and a leisure programme spread across multiple private floors. The design responds to the same regulatory logic that has shaped the entire skyline of Balneário Camboriúi: the front setback grows with height — the so-called shading cone, calculated by angle from the axis of Avenida Atlântica — which tapers the tower as it rises and produces the slender bow characteristic of the city’s skyscrapers. The rule limiting the maximum number of units per plot share is what pushes the product towards very large flats, with few units per floor.

Balneário Camboriú: the address

Balneário Camboriúi is not a neighbourhood: it is the Santa Catarina city that turned high-rise building into an economic project and produced the most recognisable skyline on the Brazilian coast — a continuous wall of towers facing a crescent-moon beach. Barra Sul, where the Rio Camboriú meets the sea, is the newest and most expensive vector of that race: it concentrates the marinas, nautical access and the new generation of signature towers, and it is where FGi chose to raise the tallest of them all. Density has a price — the wall of towers shades the sand in the late afternoon, and what can be built in front of it is a permanent political issue in the city.
