But the mass-circulation newspaper Bild, which first reported the choice of base, said coach Joachim Loew was not happy with the hotels being offered and decided on the new camp.
The project is financially supported by a German entrepreneur, the DFB said.
The base location allows relatively short flights to Salvador, Fortaleza and Recife. Germany plays Portugal on June 16 in Salvador, Ghana on June 21 in Fortaleza and the United States on June 26 in Recife.
The German team will fly to Brazil on June 7 and will prepare for the tournament at its base.
Germany is seeking its fourth World Cup title and the first since 1990. The last major title Germany won was the 1996 European Championship.
After a friendly against Poland on May 13, the Germans will train for 10 days at the end of May in Alto Adige, a German-speaking region in northern Italy.
A friendly against an opponent to be still determined is scheduled for Moenchengladbach on June 1, and another in Mainz on June 6, one day before the team flies to Brazil.
Germany also plays Chile on March 5 in Stuttgart.
