Casa Modernista, Modernist house in Pacaembu, São Paulo, Brazil

Casa Modernista, officially Residência Luiz da Silva Prado, is a 1930 house at Rua Bahia 1126 in Pacaembu, designed by Gregori Warchavchik. Its clean facade juxtaposes cubes, with a tall vertical window in the entrance hall on the south side; bedrooms and social rooms face north. The sloping plot is handled with a terraced garden on reinforced-concrete walls, plus long verandas and windows.

Gregori Warchavchik designed this house in 1930, the last of his three modernist houses in São Paulo after Rua Santa Cruz (1927) and Rua Itápolis (1930). It was built for Marina Medici Misasi, who lived there with her husband Túlio Misasi, and is officially named Residência Luiz da Silva Prado. Because its modernist repertoire covers the whole scale of the building, it is considered his most accomplished work.

The house is officially named Residência Luiz da Silva Prado, though it is known as Casa Modernista da Rua Bahia. It was originally registered to Marina Medici Misasi, who lived there with her husband Túlio Misasi. Today it is a private residence and houses a design office; it is not open for public visits.

The house at Rua Bahia 1126 is a private property in residential use, today occupied by a design office, so there are no public guided tours of the interior. Visitors can see the clean facade and the terraced garden on concrete retaining walls from the street. The sloping Pacaembu lot gives the house its vertical organisation, with the entrance hall and its tall vertical window on the south facade.

The house's stepped garden, laid out on concrete retaining walls, follows the slope of the Pacaembu terrain and forms a geometric pattern that recalls a Cubist garden. The plot measures 765 m², with 20 m of street frontage and a depth of 36.75 m on the left side.
