Residência Vilanova Artigas II, Modernist residence in Campo Belo District, Brazil.

Residência Vilanova Artigas II is a concrete residential building featuring geometric forms and a butterfly-shaped roof with yellow, red, and blue color accents. The structure sits on a substantial plot of land and stands alongside an earlier residence designed by the same architect.

The residence was designed in 1949 by architect João Batista Vilanova Artigas as his second private home. The project followed his earlier residential work from the 1940s and demonstrates the evolution of his architectural thinking.

The living room, the largest and most important room in the plan, hosted meetings of the Brazilian Communist Party, of which Artigas was a member, and gatherings of the 1960 student movement organised by his children's classmates. The house also has no maid's room and no backyard, a deliberate break with the patriarchal and slaveholding tradition of São Paulo homes.

The house stands on a 1,000 m² lot in Campo Belo, in São Paulo's southern zone, with the 1942 "casinha" still standing beside it. There is no wall along the street, only a hedge of plants marking the boundary, so the butterfly roof and glass panels can be seen from the sidewalk. The grounds are private; arrange any visit in advance.

The house has no service room and no backyard, a deliberate break with the patriarchal and slaveholding tradition of São Paulo homes. Artigas, a Communist Party member, also hosted party meetings in the living room, and his children's friends met there to discuss the 1960s student movement.
