The land, located at Bogensee - around 15 miles north of Berlin's center - was gifted to Goebbels by Hitler in 1936. There, Goebbels built a sprawling, 70-room complex, complete with a private cinema, bunker and SS barracks.
The construction was co-financed by the German film company UFA, which was a major tool for spreading hateful, fascist and antisemitic Nazi propaganda.
Historians claim the location as the site where Goebbels had several extra-marital affairs with young actresses, including Czech film star Lida Baarova, before moving his family into the house.
Since the reunification of Germany, the complex has fallen to disuse, with the Berlin municipality failing to sell the property due to its troubling history and high maintenance costs, estimated by local media to be around €230,000 every year.
According to a statement by the group, the museum's mission is to deal with the history of the site's "two totalitarian regimes," while also preventing the building from becoming a "historical revisionist pilgrimage site" for neo-Nazis.
While Berlin politicians have considered demolishing the complex in recent years, talks are now underway between the LKC Bogensee group and Berlin authorities to consider the initiative, so long as the project can be completed in a time frame of under ten years, The Art Newspaper reported in February.
The group plans on funding the project through a mix of crowdfunding and private funds.
According a report published on Friday by the UK's Daily Mail, they are already in discussion with a local renewable power company, Barnim Energie, about supporting the plans.
