The model Fuhrerbunker is planned to be opened to the public this summer.
"We're just in the planning stages, the architects are working on it," museum Ingo Mersmann told the Local.
Five rooms of the infamous Berlin bunker will be recreated, including Hitler's rooms and his secretary's office.
However, the bunker will not be in the German capital but in western Germany, near Duisburg.
"We want this to be an educational experience so that families or groups of school kids can see how it really was; to experience the tiny rooms and the dampness of the bunker. We want to recreate it to show people," said Mersmann.
Hitler lived in the bunker from January 1945, married Eva Braun there in April of the same year before committing suicide soon after.
The bunker was stormed by Soviet troops in 1945 as the Nazi regime finally collapsed and was destroyed two years later.
It is now the site of a car park.
