From 7 March to 31 May 2026, Brazilian architect Eduardo Longo's Casa Bola will open to the public for the first time. The futuristic ball-shaped house in São Paulo will host one of the two parts of the ABERTO5 exhibition, alongside a project on Faria Lima, a major avenue at the heart of the city featuring landmarks by architects such as Ruy Ohtake and Isay Weinfeld. Founded in 2022, ABERTO is an exhibition platform that promotes the encounter of architecture, art, and design in Brazil and internationally. After its first international exhibition at Maison La Roche in Paris, ABERTO returns to São Paulo for its fifth edition, presenting over 60 art and design pieces by 50 Brazilian and international artists. According to architect and curator Fernando Serapião, Casa Bola represents one of the most radical works of Brazilian architecture, challenging conventional domestic space and reflecting Eduardo Longo's experimental vision for housing.

In Latin America, encounters do not necessarily arise from grand architectural gestures or monumental urban plans. Instead, they emerge from the between, from intermediate spaces: the courtyard, the veranda, the sidewalk, and the shared corridor. These spaces, often considered residual or informal by traditional disciplines, are precisely where daily life builds connections.
This Latin American culture fosters a spatial logic in which daily life is organized in a relational and expansive way. Practices such as sitting at the front door, occupying the sidewalk, and playing in the street produce a lived city that extends far beyond the formal boundaries of design.
Living in residences designed by renowned modern architects is a dream sought after by many. Projects that have become iconic are major attractions for new residents who value both the authorial signature and history of the building, as well as the innovative architectural solutions that have contributed to the prominence of such projects.
As for the work of Oscar Niemeyer, fluidity and flexibility may best express his plans and typologies. These features provide great potential for the architects working on renovations within these buildings. São Paulo’s Copan Building is a prime example: its 1160 units, spread over six blocks, vary from 25m² studio apartments to larger units of over 150m². Niemeyer’s extensive portfolio includes other residential landmarks in São Paulo — like the Montreal, California, and Eiffel buildings — plus others in Belo Horizonte and Brasília, even reaching as far as Berlin with the Interbau Apartment House.
