Concrete as Legacy

Chu Ming Silveira, Tomie Ohtake, and the Ohtake family lineage define a strand of São Paulo Brutalism that is intimate, expressive, and increasingly at risk of disappearing.

São Paulo Brutalism does not announce itself through scale or civic ambition but through something more intimate; the conviction that a family home, built from exposed concrete and surrounded by tropical greenery, can be as expressive as public sculpture and as personal as a self-portrait. Three houses, two architects, and one family define this tradition. Together, they constitute one of the most significant and most overlooked bodies of residential architecture in Brazilian modernism.

Chu Ming Silveira arrived in São Paulo from Shanghai and built her Morumbi residence in the early 1970s with the same material directness that defined her most famous creation — the orelhão, the ear-shaped public telephone pod she designed in 1966, whose prototype stands outside the house reflected in the swimming pool. She called her approach post-caiçara architecture: a modern rereading of early Brazilian stucco lodgings in raw concrete. Half walls, low ceilings, and unusual angles create what The World of Interiors describes as a groovy brand of Paulista Brutalism — thick concrete in close conversation with tropical greenery, functional and sensual in equal measure.

"Perhaps the public would start reevaluating these houses as a history of architecture in Brazil — and the city, of course." — Filipe Assis, founder of ABERTO

Across the city, in Campo Belo, Tomie Ohtake's 750-square-metre atelier house — designed by her son Ruy Ohtake as one of his first major projects and used as her home and studio until her death in 2015 at the age of 101 — speaks an entirely different formal language. Where Silveira is angular, Ruy is curvilinear: wavy lines, cut-outs, and blocks of primary colour influenced by Le Corbusier and echoing his mother's ribbon-like public sculptures in red, yellow, blue, and green. The architecture is an extension of the art it was built to house.

A third house completes the lineage. A 1978 Ruy Ohtake residence in Alto de Pinheiros — recently renovated by his son Rodrigo — carries the unmistakable Ohtake language: expressive concrete, sculptural geometry, an architectural rhythm shaped by light. The renovation introduced new openings, a glass-covered garden, and updated infrastructure without disturbing the concrete core. Burle Marx's original garden design remains, the jabuticaba trees mature, the pool heated. The building sits comfortably in the present without pretending to be of it.

All three houses are at risk. São Paulo's property boom and the temptation to demolish street-facing homes in desirable neighbourhoods makes unlisted buildings acutely vulnerable. It was this threat that led art advisor Filipe Assis to found ABERTO — a travelling exhibition platform that stages art shows in private architectural spaces, raising awareness of treasures hiding in plain sight. Perhaps, he says, the public would start reevaluating these houses as a history of architecture in Brazil. It is, at minimum, an argument worth making in concrete.

Key takeaways

• Chu Ming Silveira's Morumbi residence and Ruy Ohtake's Campo Belo atelier house for Tomie Ohtake, both built around 1970, share exposed concrete and tropical greenery as common material ground while diverging entirely in form — Silveira angular and functional in her post-caiçara approach, Ohtake curvilinear and chromatic in direct dialogue with his mother's ribbon-like public sculpture.
• The Ohtake family's 1978 Alto de Pinheiros residence, recently renovated by Rodrigo Ohtake, demonstrates how São Paulo Brutalism can be updated without erasure — new openings carved into concrete, a glass garden added, infrastructure modernised, and Burle Marx's original landscape preserved — sitting comfortably in the present without pretending to be of it.
• All three houses are at risk from São Paulo's property boom, which makes unlisted street-facing homes in desirable neighbourhoods vulnerable to demolition — a threat that led art advisor Filipe Assis to found ABERTO, a travelling exhibition platform that stages art in private architectural spaces to raise public awareness of these buildings as an irreplaceable history of Brazilian modernism.
