Building Over The Waves, Modernist residential building between Pitangueiras and Astúrias beaches, Guarujá, Brazil

Edifício Sobre as Ondas is a residential building between Pitangueiras and Astúrias beaches in Guarujá, Brazil. Its curved plan, signed by Oswaldo Corrêa Gonçalves and Jaime Campello Fonseca Rodrigues, follows the shoreline. It holds 44 one-bedroom, 22 two-bedroom and 22 three-bedroom apartments, plus three rooftop units, one originally a communal hall. Built without foundations, it sits directly on the rock.

The project was approved by the city on 26 October 1945, and construction began the following year on the site of the former Hotel Orlandi, bought by Antônio Roberto Alves Braga. Architects Oswaldo Corrêa Gonçalves and Jaime Campello Fonseca Rodrigues signed the design; Rodrigues died during the works. The official inauguration came only on 17 July 1951. The project was shown at the Milan Triennale and won an award at the IV Pan-American Congress of Architecture in Lima.

The building's name comes from its curved plan, which makes it "embrace" the sea between Pitangueiras and Astúrias beaches. The project was shown at the Milan Triennale and won an award at the IV Pan-American Congress of Architecture in Lima. Writer Geraldo Anhaia Mello requested its listing as heritage.

The building sits between two beaches and is easy to reach on foot from the surrounding area. Access to the exterior is open for viewing, but remember it is a private residential space, so exploring from the outside perimeter is the appropriate way to appreciate the architecture.

The curved ground-floor slab that forms the mezzanine was cited by Oswaldo Corrêa Gonçalves in Arquitextos as an influence of Oscar Niemeyer. The building rests directly on the rock without foundations. The project was shown at the Milan Triennale and won an award at the IV Pan-American Congress of Architecture in Lima.
