radical and spherical 'casa bola' to host upcoming sao paulo exhibition ABERTO5
"For ABERTO5, the itinerant exhibition series is set to open next month at Casa Bola, Eduardo Longo's spherical residence in São Paulo, opening the architect's private home to the public as the setting for its fifth edition. From March 7th to May 31st, 2026, ABERTO returns to Brazil after its Paris chapter at Le Corbusier's Maison La Roche (read more here) and shifts its attention to one of the city's most unique dwellings."
"Casa Bola, the sculptural home of the upcoming ABERTO5, seems to float above the roof of Eduardo Longo's home in São Paulo. The spherical structure reads from the street as a pale volume suspended in air. The eight meter diameter 'ball' hovers over a concrete base, its curved shell catching light in soft gradients across plaster and ferrocement. A narrow stair leads upward along the edge, compressing the approach before the interior opens into a single continuous surface."
"For ABERTO5, the organizers treat the geometry of Casa Bola as a working condition. More than sixty new and recent pieces by Brazilian and international artists will be installed across roughly 1,000 square meters that include three levels, the terrace, and the spherical volume itself. Works are conceived in response to the house, placed along ramps, tucked into niches,"
ABERTO5 stages an itinerant exhibition inside Casa Bola, Eduardo Longo's spherical residence in São Paulo, from March 7 to May 31, 2026. The venue is an eight-meter-diameter sphere that appears to hover above a concrete base and reads from the street as a pale suspended volume. Longo built the structure by hand between 1974 and 1979 using ferrocement over a mesh of recycled steel tubes, applying the same material language to walls, furniture, lighting, and sanitary fixtures so corners disappear into continuous surfaces. Organizers commissioned more than sixty new and recent works by Brazilian and international artists, installed across three levels, the terrace, ramps, niches, and the spherical interior in direct response to the home's geometry.
