Edifício Itatiaia, Protected residential building in Campinas, Brazil

Edifício Itatiaia is a 15-storey apartment tower by Oscar Niemeyer on Rua Irmã Serafina, 919, in central Campinas. Its straight front faces the street while the rear, facing narrow Rua Coronel Rodovalho, curves like the Copan in São Paulo. Brise-soleils cover both facades, and the ground floor stands on V-shaped pilotis.

The idea came from businessmen Ralpho Fonseca Ribeiro and Ruy Hellmeister Novaes, later twice mayor of Campinas. A 1951 plan for a 15-storey block on pilotis failed because its architect, a Frenchman known as Charles Victor, lacked a professional licence. Oscar Niemeyer took over, and the project was launched in the Correio Popular on 23 November 1952; the habite-se was issued on 11 February 1957. In April 2011 the Conselho de Defesa do Patrimônio Cultural de Campinas listed it as a protected asset.

The name Itatiaia comes from a Tupi-Guarani word meaning "pointed rock". The building was launched in 1952 by the Ribeiro Novaes construction firm with a newspaper advertisement in Correio Popular calling it "the high point of Campinas architecture". One of its promoters, Ruy Hellmeister Novaes, later served two terms as mayor of Campinas (1956-1959 and 1964-1969).

The building stands at Rua Irmã Serafina, 919, with its straight front facing that street and its curved rear facing the narrow Rua Coronel Rodovalho. The plot keeps an 8-metre setback at the front and 15 metres at the back. The ground floor holds 47 parking spaces for the 60 apartments, and interior access is limited to residents.

The Itatiaia's floors use lost-box slabs, with upper and lower tables and an inert filler between them, so no beams cross the 15 storeys; the first-floor slab transfers loads to the ground-floor pilotis. The V-shaped pilotis once let people walk freely between Rua Irmã Serafina and Rua Coronel Rodovalho, until walls and gates closed the passage.
