Gregori Warchavchik designed the house for his own family, intending to challenge the prevailing colonial and eclectic architectural styles of 1920s São Paulo.
The house caused a public scandal during its 1930 opening exhibition because it lacked traditional ornamentation and plaster moldings.
The mansion was built using innovative, rapid construction techniques including brick and reinforced concrete that were unusual for residential projects at the time.
The surrounding gardens were designed to incorporate native Brazilian flora, moving away from the European-style formal landscaping common in the era.
The property was declared a historic heritage site in 1984 to prevent its demolition during urban expansion.
In 2004, the site underwent a major restoration project to stabilize the structure while preserving the marks of time and decay.
Casa Modernista is recognized as the first modernist residence built in Brazil, designed by architect Gregori Warchavchik in 1928. It serves as a precursor to the modernist architectural movement in the country, predating the more famous works of Oscar Niemeyer. The structure is located within a 14,000-square-meter urban park known as the Parque Modernista. The house features a stark, functionalist design that emphasizes geometric shapes and a lack of decorative ornamentation, reflecting the avant-garde aesthetic of the 1920s. Today, the property functions as a house museum operated by the municipal government, showcasing original design concepts and historical renovation layers. Visitors can explore both the interior remains of the mansion and the surrounding public garden. The site is a protected historical landmark, registered by both municipal (CONPRESP) and state (CONDEPHAAT) heritage authorities.

Do not expect a fully furnished historic mansion; the site is preserved as an architectural fragment and historical shell.
Closed on Mondays.
Stay on marked paths in the garden and do not touch the interior architectural surfaces.
